Installing autostart on a carburetor engine. increasing the level of comfort

Autostart is installed on a carburetor engine in order to increase the comfort of the car owner. The device, which has a unique automatic start function, provides a lot of convenience to the car owner when driving a car, especially in winter.

In the summer heat, this function allows you to reduce the temperature inside the cabin; it is enough to activate the car’s climate system using autostart.

By simply pressing a button on a special remote control, you can prepare your car for a trip before arriving at the garage.

Autostart on carburetor.

Greetings to all forum members. I was about to take the car. Here they offer a 1992 Honda Civic Ferio, an engine with two 1.5 liter carburetors. Question: is it possible to use it with automatic start? This is very important for me (automatic start), otherwise they told me that basins have carbs. Autorun is not installed... Thanks in advance.

  They are being placed. And on carbs with an automatic air damper and on the most ordinary carbs with manually controlled “choke”. Naturally, with the addition of automatic air damper control.

• what a lovely car you have! My brother had one like this! also on a stick. this is a damn bullet! By the way, unlike the VAZ carb, NOTHING has NEVER clogged or stuck on the Honda. I didn’t warp or cough. And on the nine-wheeler, once a year I went to clean and adjust this hellish unit.

• It warmed up without any leaks. everything was automatic. It was a funny moment that somewhere from -25 to -28, when starting the car, it started to act up. but below -28 and below, everything became good again.))))

  There was a starletina on the carburetor - the same story, never bothered, did not cause any problems at all. Now my father-in-law rides it - everything is still the same.

  Started in cold weather better than the injector. In principle, I didn’t know about the problem of flooded spark plugs. The only “but” is that you need to press the gas once or twice before starting, otherwise it will take a long time to turn it. Therefore, with autorun things may not be so smooth. Although if you set the period to a couple of hours, everything should be fine.

  – Don’t go to work, there are only inadequate people and morons waiting for you there. - Well, why not go, they’re waiting?

• The only “but” is that you need to press the gas once or twice before starting,
  this is the essence of starting on the carb =)

  there, to start, the damper must be in a slightly open position. When you press the gas before starting, the throttle turns into it (a click is heard). in any case, such a system was used in Japanese women of those years

  without this it is very difficult to start a car

  in principle, an activator for door locks is enough here, which will pull the cable before starting

  There is a crisis in the country. There is barely enough money for luxury and excess.

  And what? The option is very successful. I think partly it's the accelerator pump. The mixture gets richer and starts better when rich.

• Why do you need autostart on a carburetor??? A priori it should start in cold weather... there are no such problems as sensor calibration...

  It’s not difficult to change your mind, but here’s the problem – you can change your face, but never your soul.

  what do you mean why? What if the car were warm? What about warming up according to the temperature during the cold period?

• Why do you need autostart on a carburetor???
  A priori, it should start in cold weather... it doesn’t owe anyone anything. exactly the same problems as in the injector - viscous oil, poor volatility of gasoline, and problems with mixture formation are added

  calibration of sensors is some kind of gag

  something rare :) I went for adjustments every six months, and I also got tired of turning this damn carb myself!

• Our non-Russians simply trained and tuned them well. It was almost enough for a year. But this knot is frankly * amno on zhiguars. One day, after 2 hours of dancing around, in the summer, I healed myself!! **hit it twice with a hammer - and it started and rattled...

Is it possible to install an alarm with auto start on the carburetor?

The carburetor itself is not designed for the installation of additional equipment in the form of autostart, so you have to seriously tinker with this point. Especially when it comes to installing an alarm system on a domestically produced VAZ car.

Let's consider the difficulties that you will encounter when doing the installation yourself:

1. Difficulty in assembling the autostart mechanism.
2. Possible problems with wiring to the carburetor.
3. The fuel supply system remains unchanged, which further complicates the procedure.
4. VAZ cars are extremely capricious and require proper handling when carrying out repair or tuning work.
5. The engine is warmed up using a manual choke, which also needs to be converted into an automatic speed control.
6. The final stage of difficulty will be to combine all this into a single circuit and program autostart from the alarm key fob.

As a rule, all these issues will be faced by a fan of domestic vases who wants to completely remake the car so that the engine can start comfortably even in severe frosts.

What is needed to ensure autorun

To ensure autostart, you will need not only an automatic control system, but also a special alarm system with the above-mentioned function. The car engine must be in good working order and start from the first revolutions of the starter. The fact is that a correctly connected and configured alarm system gives a signal to start the engine for no more than 3 seconds. If during this time the power unit does not start, the key fob will notify you about this.

Since the carburetor is a rather delicate mechanism, it needs to be adjusted every 20 thousand kilometers. It is advisable to have this done by professionals who will perform calibration using a gas analyzer. At the same time, it is necessary to check the settings of the ignition system using a strobe light, and, if necessary, set the required OZ. If the fuel supply and ignition are misregulated, then there can be no talk of any autostart. It’s good if the car can just be started.

Installing autostart on a carburetor engine. Increasing the level of comfort

For many drivers, installing autostart on a carburetor engine is something unrealistic. In fact, this is quite possible. With this device, your car will immediately become more comfortable. It will be possible not to shake in a frozen car, waiting for it to warm up. Just press a button on the remote control and the car will be completely ready for your trip when you leave. Autostart has especially many advantages in winter. By programming it to start at certain hours, you can be sure that in the morning it will easily start in any frost. But this matter is far from so simple. Installing autostart on a carburetor engine is quite complicated. It is not enough to purchase and install an alarm system with this capability. The structure of any carburetor does not in itself provide for the installation of such gadgets. But you can fight this. Installation

. In cars with such carburetors, the on-board computer is completely absent, as unnecessary. The fuel flows independently through the pipeline. It also enters the cylinders on its own, flowing there through the intake manifold. The role of the metering valve is performed by the carburetor. No fancy electronics required here. Therefore, there is no on-board computer on such engines. But you can still set up autostart without replacing the fuel supply system.

Features of installing an autostart system in carburetor power units

Cars with carburetor engines are not equipped with on-board computers, since they are not necessary. This is the main difficulty for equipping such machines with this starting system. Car owners often wonder how to install autostart on a carburetor engine. This possibility exists.

List of necessary equipment for self-installation of automatic start:

• signaling;
• microcontroller in the form of a special chip;
• temperature sensor;
• electric motor;
• cable;
• cables.

I liked SAUVZ-8 more. I've been using it for a long time. There are various settings, the presence of settings for additional outputs, configuration from a smartphone via Bluetooth without leaving home. Three damper control modes, automatic warm-up, self-learning driving mode on a cold engine, and manual mode either using buttons or from a smartphone from home.

I bought this device for myself a long time ago. But I still haven’t put it in... My hands can’t reach it...

I have such a device. Having calibrated correctly, you can forget about the suction. But due to the transition to motorcars I have to say goodbye to it ((

how much does it cost? Where to buy?) How is it configured? via computer?

Google it please! I can’t post a link, they’ll punish me for advertising! I can PM you if you can’t handle Google!))

And for me too, if it’s not difficult) it’s a very interesting thing)))

Google it please! I can’t post a link, they’ll punish me for advertising! I can PM you if you can’t handle Google!))

Write to me too - I wonder what and how much...

how much does it cost? Where to buy?) How is it configured? via computer?

And me too, please. I’ve been looking for such a device for a long time and haven’t found anything suitable.)

Cool, I've never seen such things!

That’s why I posted it... to convey it to the people on a silver platter... I believe that... many people thought about this... but had no idea how to make it a reality. )))

I heard about a similar system, only from a different manufacturer - SAUVZ (automatic air damper control system), they have their own website. I wanted to put it on a six, on a carb, but I never got around to it)

Southes seems to be the same...I read that people say it’s better...but more expensive...fact!

Let’s say I have a car that runs on gas, also carb. Sometimes during hard braking it stalls when the revs are low. At such a moment can it add fuel on its own so that it doesn’t stall?

No! The device monitors all units in warm-up mode! When it warms up... It opens the throttle completely and is inactive... until the engine cools down!

What about in winter? the oil in the box is still thickening

I’ve always wondered how Silych’s reliability was. Plus, as described below, the design is not thought out for the forced closure of the valve if the Solex is produced.

For this, push-button control is additionally displayed. ))

What's the point of the button? Well, if you press it, the damper will close completely. This number will not work on a Solex. If there is a blockage, it is not a fact that it will work on a warm engine with the throttle closed.

What's the point of the button? everything works the same as with a cable! You need to open it a little... you press and open it... you need to open it a little... halfway... completely. )))

Oh, I drove in, there’s a stepper motor there. Well then - yes. Do they make this exit on a button or do they farm it themselves?

There is a connector on the gearmotor...a button is connected to it...

On the manufacturer’s website, all components are sold separately...))) In order...to reduce the cost of the product...what if you don’t need a button...or a fastener...etc. Why overpay. )))

I have a Silechevsky fan control, an excellent thing. And his own auto-corrector.

Normal topic...the price is too high, it seems to me. )))

This is) A boiling engine will cost more, and a corrector was needed to legitimize the lenses)

I'll come and read about the lenses. )))

Pressed the button in the cabin! I opened the damper and forcibly turned off the gear motor from the passenger compartment! Everything is completely the same as mechanically... pull the cable! + another device with brains for autostart. ))

The standard cable is removed! The device is controlled from the interior using buttons. )))

Great gadget! Now we need to introduce a clutch drive and a servo drive on the gearshift lever and the basin can drive itself for beer)))))

Krasava))) And on what parameters is the control of the suction gearbox based?

Thank you! Based on: temperature, time, engine speed. )))

Cool solution! Geared motor from stove 10, very similar?

where can I get it? Interesting device)

Friend, google it please! I can’t, they’ll punish me for advertising! I can PM you if anything happens. ))

Yes, I already found it, it’s a good thing, but the kit is a little expensive

It's worth it! In my region, it’s not a varik without autostart... It’s cold. )))

In the first photo, the sticker on the bottom really says KAMAZ :), very interesting, after all, what kind of model is in the first photo.

And the embryo of KAMAZ, then it’s clear, by the way, such similar regulators have been produced in Ukraine for a long time, only they were used mainly in Tavria and Slavuta, and those who installed the mpsz on their cars, there the adjustment bolt is built into the mpsz and it is not necessary to adjust if the mpsz is installed. There is one problem with them, this is the cleanliness of the carburetor during the operation of the car, you need to make sure that there is no dirt and other things there, since over time even such a machine may simply not pull the valve or return it to its original position, there is already experience using a similar headset on another auto.

We install autostart with our own hands

Before you begin the installation work of the autostart on the VAZ, you need to prepare everything required for this. Installing one alarm will not be enough; it will require long and painstaking work. To bring your plan into reality, you will need to prepare the following:

Scheme for installing autostart on a carburetor
You can begin assembly by turning off the manual choke, which is installed on any VAZ carburetor engine. In this case, you don’t have to pull out the cable, but secure it securely under the hood. There is a high probability that it will be useful for something in the future. If you have an auto choke on your car, then it will have to be completely disassembled. The carburetor is completely disassembled and all sensors are removed from it. The last step before assembly is to switch the feed drive to external.

Stages of installing a do-it-yourself autostart on a carburetor

To install a start-up signal on a carburetor engine, the following series of actions must be performed sequentially:

1. First of all, all the components of the structure are placed in their places. The electric drive can be installed on the engine wall. The temperature sensor is mounted on the engine. You should not use an old sensor, as there is a high probability of making a mistake. The microcontroller will need to be placed next to the electric motor, although in some situations it is better to attach it to the carburetor.
2. Using a previously prepared cable, the engine is connected to the damper.
3. All parts of the suction pump should be connected to a microcontroller, which in turn has a direct connection to the signaling system.
4. Next comes a test test, if the system gives a response, then you can move on to the next stage, if there is no feedback in the carb, then you have to recheck the entire connection again.
5. The entire system is tested and brought to perfection. The microcontroller will have to change several operating modes taking into account the temperature sensor readings. You should also adjust the length of the cable as much as possible. Once the system has been tested, the first test run can be performed.

Important. Every car enthusiast can install an autostart with his own hands, but not everyone has the patience to cope with setting up and bringing the work to perfection.

The final stage of installing autorun

It is possible to fully start the engine using the key fob only after installing the air damper servomotor. The device, as a rule, is placed on the wall of the engine compartment, while others, on the contrary, try to mount the element directly on the carburetor. By installing this element, you can forget about the position of the air barrier. This device is produced under the Sadko brand. The model is produced in two types:

1. Standard equipment, which includes a microcontroller, control unit, cable, electric drive and temperature sensor.
2. The maximum configuration, which contains all the previously listed devices, as well as some additions.

The maximum configuration of "Sadko" is distinguished by the following indicators:

• Having received a signal from the alarm key fob, the damper automatically opens slightly;
• Next comes fuel injection;
• after which, due to the control unit, a spark is supplied, which starts the engine for warming up.

If you decide to give preference to the standard set, then you will have to manually configure the entire system, since there may be a problem due to inaccurate calculations and installation, namely:

• The ignition is turned on first and the damper is closed manually;
• after the engine is running normally, you have to close the damper again with your own hands;
• after waiting for some time, you have to completely open the fuel supply;
• the machine should run for some time at idle speed without outside intervention;
• At the end the engine stops and cools down completely.

Upon completion of everything, all that remains is to test start the car with a button from a certain distance, which is accessible for the alarm.

Important. If everything was done correctly during manual setup, the device will automatically repeat your actions, thereby starting the engine for operation and warming up.

Installation and connection of additional elements

Many cars do not have hood, trunk, or fuel filler door sensors. You can purchase limit switches, connect them in parallel and connect them to the control input. This is how, for example, they install the hood button:

One subtlety must be taken into account - the “open” position must correspond to a closed state. Installation is carried out in the following sequence:

1. Secure the switch body;
2. Additional wires are passed through the seal where the hydraulic corrector tubes pass;
3. Connect the sensor, and at the same time the siren.

Now let’s add movement control to the car, that is, the alarm will “know” whether the car is actually moving.

Connecting to the speed sensor

Let's talk about the "Seven" with an injection engine. Then the speed sensor is installed and connected from the factory. It will be easy to find the contact of this sensor:

As you can see, you need to make a tap connected to one ECU terminal (1/59). Here we are talking about the control unit, that is, the standard engine controller.

Not every alarm system has a separate input connected to the speed sensor. But if the connection is still made, take care of good contact with ground. Under the “dashboard” there are two copper studs connected to the body. One of them is located near the ECU, and it is better to connect to it (see figure).

It would seem that the speed sensor is a fairly simple additional device. And if this element is missing, you can buy it and install it yourself:

The sensor housing must cover the hole in the gearbox housing. Everything looks simple, and you can do the installation yourself, but the tightness of the assembly will then be broken. In general, it's better not to take risks.

Advantages and disadvantages of a carburetor engine autostart system

The autostart system has the following advantages:

1. Comfortable temperature in the cabin at any time of the year, both summer and winter.
2. Significant savings in time spent starting the engine.
3. Possibility of programming to turn on the engine at a certain time.

A device built into the system, called a turbo timer, allows you to gradually stop the turbine of the power unit, significantly increasing its resource.

The disadvantages of automatic start include the following system features:

• increased fuel consumption;
• accumulation of condensate in the exhaust pipe with subsequent icing;
• freezing of the parking brake and brake pad cables when the vehicle is fixed in neutral gear;
• there is a danger of car theft, because when the autostart is turned on, the security system is turned off.

Frozen brake pads and discs are restored using a special defrosting fluid or hot water. By rocking the car back and forth in order to break the ice shackles, the brakes are brought into working condition.

When the parking brake mechanism is weakened, special wheel chocks are installed under the wheels.

Car owners are increasingly coming to the conclusion that in harsh winters and hot summers, installing modules for automatically starting the power motor is a reasonable action.

Only after carefully studying all the pros and cons inherent in this system, you need to make the right decision about the advisability of equipping your car with an additional function.

What is SAUVZ?

What is it and where is it used

SAUVZ stands for automatic air damper control system. Used on carburetor engines, installed to facilitate starting at any time of the year, mainly popular on cars with automatic start, since a person, being away from the vehicle, is unable to control the air intake damper. If you start a car without an automatic control system using the key fob in the cold season, the engine is unlikely to start.

What cars can it be installed on?

Can be installed on any carburetor car. Most often, the system can be found on VAZ 2101, 2102, 2103, 2104, 2105, 2106, 2107, 2108, 2109, 2110, 21213. It is also found on Volga, Moskvich and other Russian automobile industry of the last century. The system is easily installed on carbs such as Ozone and Solex.

Installation is also possible on a variety of foreign cars equipped with a carburetor without automatic choke. Yes, many Japanese and European cars had such a mechanism installed from the factory, however, few engines have survived to this day in which the SAUVZ works correctly. Therefore, when purchasing a system, you should make sure that the carburetor of your car does not have an automatic choke control system. If it is present, then the best solution would be its restoration.

Device and principle of operation

It works extremely simply. This is an electronically controlled gearmotor: the microcircuit sends signals to the choke damper control element, in turn, the “brain” takes readings from the coolant temperature sensor and the hall sensor. The control unit has a graph of the dependence of the required amount of air on the engine temperature, and the step reducer, based on the signals, closes the suction to the required amount.

Price

Prices for auto choke kits are quite high: for a good kit you will have to pay about 4,500 rubles. For this money you will receive a gear motor, a control unit and a set of wires, as well as a cable and a program for setting up the system.

Everything would be fine if it were not for the injector, which is gradually replacing the old fuel supply mechanism. For example, a kit for installing a fully electronic fuel supply for a front-wheel drive VAZ will cost 6-7 thousand rubles. Naturally, this will be a used device, but there is practically nothing to break there. But you will get a fully automated injection system that does not require adjustments. Fuel consumption will decrease and power will increase. In any case, it's up to you to decide.

The process of installing autostart on a carburetor car

Carburetor cars are still in great demand in the secondary market today. Therefore, installing autostart on a carburetor is a fairly pressing topic. With carburetor cars, serious problems often arise when starting from cold, especially at extremely low temperatures below -25°C. In this article, we will look in more detail at how autostart is installed on a carburetor using the example of a domestic VAZ 2107 car.

LED scales “Photon-2” and “Photon-4” for visualizing the work of “Sadko2”

“Foton-2” has one scale, displays only the position of the air damper

“Foton-4” has two scales, displays the position of the air damper and the engine temperature using the “Sadko-2” temperature sensor

The LED scale is designed to visualize the position of the air damper by connecting to the rotary resistor on the gearmotor. The damper position is indicated by a lit “column” of LEDs. The second scale (on Photon-4) is made of colored LEDs and displays the engine temperature, units and tens of degrees, there is an overheating warning mode. The LED scale is made in the form of a waterproof module in transparent heat shrinkage measuring 30mm x 10mm. The module can be secured in a convenient place with double-sided tape or in any other way.

Visualization of the controlled parameter is possible as a column of variable height or a “running” point.

Fasteners

Let's start assembling the fasteners. It is ordered as a separate line on the order form. It is also included in both sets (first and second line in the order form). The minimum Sadko kit in the order form consists of an electronics unit with wires, a gear motor, an internal combustion engine temperature sensor and fasteners.

The fasteners include: a plate, bolts and washers, a traction lever for the cable, a cable clamp on the plate. The fastener is designed for a cable drive to control the carburetor air damper. The cable is not included in the kit and must be purchased by the buyer independently. From 2021, the plate can be used from standard industrial fasteners to maintain cost.
