The HR16DE engine was designed by representatives of the Nissan-Renault alliance, so it included the developments of K4M from the French side and QG16DE from the Japanese side. The design uses compromise solutions:
- aluminum block and two injectors per cylinder;
- timing chain drive and oil pump;
- DOHC valve timing mechanism and phase regulator on the intake camshaft;
- lack of hydraulic pushers;
- distributed injection and COP ignition circuit with 4 coils without armored wire.

After which, the internal combustion engine is used by the manufacturer of Nissan and Renault cars, and is used in cars from the AvtoVAZ plant in almost the entire line.
Generations of Nissan Qashqai and engines
Nissan Qashqai was launched into mass production in December 2006 and was equipped with:
In 2010, the model underwent modernization; in 2008, a seven-seat modification of the Qashqai +2 (in the NJ10 body) appeared, which was later replaced by the 3rd generation X-Trail SUV.
Production of the first generation Nissan Qashqai was discontinued in 2013; for Russia, the compact crossover was supplied only with 1.6 and 2.0 liter gasoline engines.
The debut of the second generation Qashqai took place in November 2013, and the range of engines for this car was slightly changed:
Since 2017, the Qashqai-2 crossover has been produced in a restyled version; the Russian updated model has been assembled near St. Petersburg since March 2021.
But it should be noted that cars from St. Petersburg are equipped only with the R9M diesel engine, 1.2L and 2.0L petrol engines; the MR16DDT engine is not available for Nissan Qashqai-2 cars assembled in the Russian Federation.
Engine oil for internal combustion engines HR16DE, recommended by the automaker
Brand HR16DE (or H4M) is a widely used 16-valve engine with a timing chain drive, installed on many Renault and Nissan cars, launched into mass production in 2005.
With normal operation and regular maintenance, the engine lasts on average 200-250 thousand km or more before overhaul, and does not have a large oil burn.
The lubricants recommended for use by the developer of this engine are original Nissan motor oils according to API classification SM or SL, belonging to the ILSAC GF-3 or GF-4 categories.
The automaker recommends using SAE 5W30 oils as an all-season oil; if this brand is not available, you can use MM that is suitable for viscosity in a given range of ambient temperatures.
What oil is used
Recommended oil for normal operation of the unit as a whole:
- 0W-30;
- 0W-40;
- 5W-30;
- 5W-40;
- 10W-30;
- 10W-40;
- 10W-60;
- 15W-40.
Oil tolerances according to technical documentation are every 1500 kilometers according to technical documentation. At the same time, the oil volume in the engine is 4.3 liters. Practice shows that it is better to replace it, especially if the car is often used in winter, every 7,500 kilometers.
Please note that if it is consuming oil, then perhaps the reason lies in problems with the oil pump. You can find out the malfunction by conducting diagnostics and measuring the exact flow rate according to the established indicators.
Alternative replacement for original Nissan oils
The use of original Nissan products is not at all a prerequisite; other lubricants that match the characteristics can be used.
To ensure that the engine runs for a long time and smoothly, it is advisable to choose synthetic types of oils; the following brands have received good reviews:
There are still many other options, especially since auto chemical manufacturers do not stand still, new developments of motor oils appear regularly.
Here it is important not to run into a fake, and you also need to know that modern synthetic oils are divided into two categories - PAO synthetics and HC synthetics.
Pennzoil Synthetics is produced by synthesis from natural gas, while HC-Synthetics uses crude oil as a feedstock.
PAO synthetics provide more reliable engine protection at high and low temperatures and have better performance characteristics, although they are more expensive.
Suitable oil according to Nissan Tiida approval
Original oil
Nissan Tiida engine oil is selected based on the temperature outside the car. In winter, lubricants should be thinner than in summer. It is better to purchase original oil from a well-known Japanese company in trusted stores and through specialized websites. Only in this case will the engine service life last longer than the stated warranty period.

For various climatic conditions, MM is selected according to the American SAE classification, where in the alphanumeric designation the first number indicates the pour point of the lubricant, the numbers after the W sign indicate the maximum thermal threshold at which the oil begins to lose its properties and liquefies.
The greater the difference in numerical values, the more versatile the motor oil is; there are also winter and summer grades.
All values are approximate, since a lot still depends on the class and composition of the liquid (synthetic varieties are more stable).
Based on the above, oils according to SAE can be divided into categories:
The oil viscosity for your region and time of year should be selected with some reserve, and in order not to make a mistake in your choice, it is better to use a special graphic table.
Modernization
Upgrade prices vary. It is important to consider that tuning can be carried out as firmware for an electronic unit or a physical upgrade of the power plant. Many drivers prefer to install the LPG system as the main one. The engine has economical consumption; in a gas installation it will be even less. Contract engines are supplied upon request without any problems.
The installation has a mass market and often the device is subject to individual upgrades using an intercooler and turbocharging. Also taking part in the upgrade are:
- crankshaft oil seal;
- front-wheel drive;
- firmware of the central control unit;
- power unit cooling system;
- tension roller.
The decorative trim is mounted on top of the main part of the engine. When carrying out repair work it will be necessary to dismantle it. Engines with an increased stroke have, as mentioned above, a significant resource, after which the components are updated or completely replaced with a pre-purchased contract unit. Chip tuning the motor of this version does not provide a significant increase in power.
The resulting increase can be up to a maximum of 5 horsepower. In reality, this will not be noticeable when moving. You should be careful about this type of firmware. Incorrect settings can significantly reduce engine life and accelerate its failure.
Engine oil for 1.6 liter diesel engine
The 1.6 dCi diesel engine (model R9M) is a four-cylinder turbocharged power unit with a maximum power of 130 hp. pp., in the Russian version it is installed on the second generation Nissan Qashqai (pre-styling).
The R9M diesel engine has been produced since 2011 and is considered a fairly reliable power unit; its main drawback is poor starting in frosty weather.
The lubricants recommended here by the manufacturer are original low-ash low SAPS oils with specification ACEA C4 (Renault RN 0720), specially designed for engines with particulate filters and turbocharging.
Description
For Russia, this engine has become attractive and interesting because it is officially installed on new models of the Lada X-Ray car at the AvtoVAZ plant. The base unit has a power of 114 hp. Previously, the device was mounted on such foreign cars as Renault and Nissan. And today it can be found on many car models from sedans to urban crossovers.
When developing the unit, engineers decided to increase the emphasis on the efficiency of the internal combustion engine. A device was introduced that allows the valve timing to be changed automatically. The intake shaft has changed its inclination while rotating.
Such innovations more than 10 years ago, since their release in 2006, have created a technical sensation, placing emphasis on high quality and economical fuel consumption in cars of this class, such as sedans and crossovers.
Emphasis was also placed on reducing the overall weight of the power unit. In this case, the developers replaced the alloy in the cylinder blocks with aluminum. Reducing the total weight of the power plant made it possible to significantly increase the service life of the suspension on the vehicle.
Oil change intervals on Nissan engines
According to factory regulations, regular replacement of the MM and oil filter on Qashqai cars should be done every 15,000 km, if the vehicle is operated in difficult road conditions - after 7,000-8,000 kilometers of travel.
To refuel 1.6-liter Nissan engines, the following oil volume is required:
Also, engine oil can be changed unscheduled or ahead of schedule if:
It is also important not to run into fakes, so you should buy all automotive chemicals only in specialized stores, and check for a certificate for the products you are purchasing.
And finally, I would like to note that shortening the MM replacement intervals does not negatively affect the engine life, but to ensure that the inside of the engine is always clean, instead of frequent maintenance, it is better to use high-quality oil from a manufacturer with a good reputation.
If you are already pouring a certain brand of oil into the Nissan Qashqai engine, then write about it in the comments, for many it will be useful information. Thank you.

Selection by viscosity grade
Every experienced motorist is familiar with indicators such as 5w30, 10w40 and so on. These numbers indicate the temperature index of use of the motor fluid. The most popular markings in the domestic space are: SAE 0w-20°/+35°C.
For countries with cold climates, oils with SAE 5w30 ratings with temperatures from -30° to +35° are most often used. In temperate zones, it is best to fill with SAE 5w fluid at the same temperature. No less relevant is a lubricant with the characteristics of 5w40.
ACEA approval should not be ignored either. This indicator demonstrates compatibility with internal combustion engines. Passenger cars Nissan Qashqai, Primera, Almera, X-Trail, Tiida, Teana, Postfinder, Murano with left-hand drive work perfectly on lubricant with A3/B4 ratings.
These are standard types from the manufacturer Nissan, marked 5w40. If it is not possible to use original products, experienced specialists recommend using oils from the company:
First of all, you should pay attention to tolerances, the company’s reputation and the final cost. However, if we talk about the price aspect, then for Nissan 5w40 oil you will have to pay around 2000-2300 rubles for a 5 liter canister. This is significantly cheaper than foreign analogues.
For passenger vehicles with a particulate filter, C4 - ACEA fluid is allowed. In this case, you can use an alternative lubricant from Liqui Moly.
Nissan sports cars require the use of oil with special characteristics. Typically, sports cars use compounds with a high level of viscosity - 10w50, 15w50. Owners of models such as Skyline or 350Z prefer to trust the opinions of service station professionals.
On such models, original products from Mobil, LM, Motul are most often used. Viscosity is selected according to the manufacturer's recommendations and engine technical parameters. Climatic conditions also play an important role in choosing effective products.

Features of the HR16DE/H4M engine
The cylinder block has two camshafts and four valves per cylinder. The camshafts are driven by a silent chain with an automatic tensioner, which is designed for the entire service life of the engine.
Thermal clearances in the valve drive are regulated by selecting pushers (there are no hydraulic compensators). The oil pump is located at the top of the engine sump and is driven by a chain. The main and additional catalytic converters are located in the exhaust pipe.
The HR16DE/H4M engine is equipped with an automatic variable valve timing system, which improves the filling of the engine cylinders in all operating modes. To do this, phase regulators rotate the sprockets of the intake camshafts relative to the shafts themselves. The phase regulators are controlled by a hydraulic drive, which uses the oil pressure of the engine lubrication system. The flow of oil is controlled by a phase change solenoid valve, which in turn controls the ECU (electronic engine control unit).
Auxiliary units (generator and cooling system pump, air conditioning compressor) are driven by a serpentine belt. Two injectors are installed on each cylinder, fuel economy has increased, power has increased slightly, and idle speed has decreased.
Thus, we can highlight the main advantages and disadvantages of this power unit:
The HR16DE/H4M engine is also installed on foreign cars: Nissan Note, Nissan Tiida, Nissan Qashqai, Nissan Sentra, Nissan Juke, etc. It has proven itself well among the owners of these cars and is an average engine.
What reviews can you leave about the HR16DE/H4M engine? Is it worth considering this power unit from Renault-Nissan instead of VAZ models? Let us remind you that on the dynamometer stand this engine confirmed the power declared by the manufacturer. You can get acquainted with domestic engines in more detail from these articles (VAZ 21129 1.6 l and 106 hp, VAZ 21179 1.8 l and 122 hp).

Design Features
The HR16DE engine developed by the Renault-Nissan Alliance received the following design features:
Cylinder block Gas distribution mechanism Phase adjustment diagram with hydraulic coupling
Since different Nissan models do not use the same ECU firmware versions, it is necessary to study the description of the parameters before using the power drive. But independent boosting and overhauls are possible as needed.
Intake manifold
During the release of the HR16DE engine, Nissan management did not use naturally aspirated or turbocharged modifications, since the basic version completely satisfied the developers. If it is necessary to increase power or reduce this characteristic for a specific market, the factory settings are changed, which the user can restore independently by flashing the version of the on-board computer software.
List of car models in which it was installed
The HR16DE naturally aspirated in-line engine was developed by the designers of the Renault-Nissan alliance for the following Nissan models:
- Juke – mini-crossover;
- Sentra – export version of the Sunny sedan;
- Qashqai – urban crossover;
- Tiida – sedan and hatchback;
- Note – subcompact van;
- NV200 – LCV-class van and minivan;
- Versa – hatchback and sedan for North America;
- Grand Livina – compact MPV for Malaysia;
- Latio – B-class sedan for Malaysia;
- Bluebird Sylphy – front-wheel drive and all-wheel drive C-class sedan for China and Thailand;
- Cube – subcompact van for Europe;
- Wingroad – utility vehicle;
- Micra is a hatchback made in England.
The French partner of the Renault-Nissan alliance owns shares in AvtoVAZ, so the HR16DE internal combustion engine device was assessed by the owners of the domestic automobile industry:
- Renault Logan – compact sedan, pickup, station wagon and minivan;
- Lada X-Ray – hatchback crossover;
- Lada Vesta is a five-door station wagon and a four-door sedan.
Nissan Cube
The engine was created for heavy loads and difficult operating conditions, including the urban cycle and off-road.

If you make any changes to the HR16DE engine mechanically, you will need to reinstall the on-board computer software version. Regular chip tuning can add about 5% power, but by itself does not solve problems.
Atmospheric tuning includes the following operations:
- reducing back pressure inside the exhaust tract - direct-flow exhaust with a cross-section of 61 mm, a spider instead of an exhaust manifold, dismantling oxygen sensors, installing one or two resonators in series;
- increasing the intake air volumes - a separate throttle for each cylinder or a zero-resistance filter with grinding of the intake manifold channels;
- modification of the cylinder head and timing belt - grinding the head, installing wide-phase camshafts.
Supercharged tuning can increase power to 160 hp. pp., but the pressure should be limited to 0.5 bar. When installing a turbine, high-performance injectors, modifications to the exhaust tract, and pistons with recesses will be required to reduce the compression ratio.
Thus, the HR16DE engine developed by the Renault-Nissan Alliance has the additional marking H4M, the combustion chamber volume is 1.6 liters and the power is 110 hp. With. The engine is considered a reliable, economical and lubrication/fuel-friendly power drive for SUVs.

Specifications
It is not the timing belt that is installed on the engine, but a chain. This increases the range and in the early stages there is no need to worry about it being stretched. The engine installed on Nissan and other brands has an average volume of 1.6 liters.
The engine model underwent factory modernization. So, 2 injectors were installed on each of the cylinders. This made it possible to significantly reduce fuel consumption. Additionally, the cylinder block increased the power of the device. Also, thanks to the modernized system, the idle speed in the cylinder head has decreased.

It is worth considering that the engine is installed on different vehicle models. As a result, there may be different volumes and capacities with consumption. Manufacturers do not have exact indicators of power gain, as well as real fuel consumption. The only thing that is indicated in dealership centers in this regard is modernized engine components, which allow significant savings in fuel consumption in different driving modes.
The engine abbreviation is given as follows:
An important point is the thermal conductivity of the aluminum alloy. Thanks to these properties, engineers were able to significantly reduce the warm-up time of the car. This had a positive effect on overall fuel consumption when operating the car.
What models are installed on?
What cars have internal combustion engines? There are many equipment manufacturers. At the same time, auto concerns have been using the engine for more than 10 years. Today the list of cars where h4m/hr16de is installed is as follows:
| car brand | Model |
| Nissan | Note |
| Nissan | Tiida |
| Nissan | Qashqai |
| Nissan | Sentra |
| Nissan | Juke |
| Nissan | Micra |
| Nissan | Wingroad |
| Nissan | Cube |
| Nissan | Bluebird Sylphy |
| Nissan | Latio |
| Nissan | Grand Livina |
| Nissan | Versa |
| Nissan | NV200 |
| Renault | Kaptur |
| Renault | Logan |
| Lada | X-Ray |
The engine is predominantly installed on Nissan cars. They can most often be found on the domestic car market. Car enthusiasts note that the engine operates well even in bad weather, frost and humid climates. The main thing to maintain normal condition is to undergo scheduled maintenance and change consumables. The h4m/hr16de type engine has its own quality standard. All engines produced from the factory have a warranty period and comply with environmental safety according to European protocols 4 and 5.
The oil pressure in the engine is controlled by a magnetic valve. It is controlled electronically in the vehicle's system.
The engine also introduced such innovations as:
Measuring the pressure in the rail will avoid the problem associated with the rapid failure of the fuel pump. The main bearings on the crankshaft journals can also be damaged due to improper operation or the use of the wrong brand of oil.
Review of faults and methods for repairing them
When the timing chain links break or jump, the HR16DE motor bends the valve with pistons without counterbores on the end surface. Other malfunctions are usually extraneous sounds:
| Noise inside the timing belt | 1) valve clearances are knocked down 2) camshaft cams are worn 3) development of valve stems/bushings 4) valve spring is broken 5) reduced oil pressure in the system | 1) adjusting valve clearances 2) replacing the camshaft 3) replacement of valves and bushings 4) installation of a new spring 5) repair or replacement of the oil pump |
| Muffled knocking noise under load at low speeds | 1) scuff marks on the cylinder bore 2) stuck oil scraper rings | 1) honing cylinders 2) replacing rings |
| Sharp knocking noise at idle when accelerating | 1) wear of connecting rod bearings 2) reduced pressure in the lubrication system | 1) replacement of liners 2) diagnostics, cleaning, oil pump replacement |
| Clunking noise when revving at idle | 1) wear of the main bearings 2) weakening of the flywheel | 1) replacing the liners 2) tightening the fastening bolts |
| Whistling | The alternator belt is loose or overtightened | adjusting tension or replacing the belt |
Repair HR16DE
Manufacturer Nissan has recalled a sold batch of cars due to a defective ignition unit relay. Otherwise, the power drive does not cause any complaints.
Common Problems
When operating a car such as a Nissan Beetle or Lada Vesta, a knocking noise may appear after a short period of use when it is cold. This may be due to the timing belt stretching. In order to check this fact, you need to make sure that the timing marks are in place. Weak compression can also be the reason why knocking occurs. The engine also has the following weak points:
- Untimely replacement of spark plugs forms carbon deposits on the contacts;
- The oil filter may cause an oil leak;
- Failure of the right engine mount.
In the last point, if the engine starts to shake strongly, this is a consequence of a breakdown. You just need to change the pillow and the knocking will go away. Another common problem during long-term use is the operation of the motor. At medium and low speeds it may suddenly stall. This type of problem can be solved by ordering a new relay for the ignition unit. For service you will need:
- Change oil and spark plugs in a timely manner;
- The valves must be adjusted manually;
- If the alternator belt becomes loose in tension, it must be replaced immediately.
Such actions will avoid more serious damage to the engine system. According to the maintenance map, all these actions are carried out according to plans. If knocking or whistling noises are noticed, you should immediately contact the diagnostics department.
Not all vehicle models face these types of problems. But as practice shows, such problems can arise during prolonged use in unfavorable conditions.
Engine 1.6 HR16DE
This Tiida engine began to be assembled in 2006 in Yokohama (Japan), and then it began to be produced in China, India and Russia (AvtoVAZ plant). In the past it was also installed on compact, inexpensive, and now completely budget cars. This unit, in addition to Tiida, is installed on other Nissan models, as well as Renault, Mitsubishi and Lada. Main parameters of HR16DE:
Engine design features
There is a chain in the timing belt. The engine has a valve timing adjustment system. The intake shaft is equipped with a phase shifter. An electronically controlled throttle valve is used. There are no hydraulic compensators, so valve adjustment may be required after 100 thousand kilometers. However, Nissan engines are famous for the fact that even at high mileage they rarely show signs of the need for adjustment; rarely does anyone pay attention to the “chirping” when cold, so the valves are adjusted closer to 200 thousand kilometers, when the oil scraper rings need to be replaced.
This motor has been modernized several times. The camshafts, cylinders, and attachments were changed. Gasoline economy has increased, power has increased slightly, idle speed has decreased, without losing its stability. The Nissan Tiida 1.6 engine now meets Euro 5 standards. Other, not very significant, transformations also took place.
The most common failures
On this engine, at high mileage, the oil scraper rings are stuck, if you get carried away at low speeds when driving, which leads to an increase in oil waste. Consumption of 500 ml per 1000 km, even on a new engine, is considered quite acceptable.
Whistle during operation, as on most Nissan engines, is associated with a loose alternator belt. The problem can be solved by tightening it, but if there is nowhere to pull it, then all that remains is to replace the belt. When acceleration in motion is accompanied by an unusually loud sound, this indicates that the ring gasket in the exhaust pipe of the muffler has burned out. The defect can be easily eliminated by replacing the gasket. A relay burnout in the ignition unit leads to the engine turning off directly while driving, without the possibility of starting. It is necessary to order a new ignition unit relay and replace it. Perceptible vibration from the engine compartment may be caused by wear on the engine mount. And first of all - the rear support, and only then - the right one. With the help of replacement, this problem can be easily solved.
Engine Nissan hr16de
The universal h4m/hr16de engine was the prototype of the model, which was an internal combustion engine from Renault.
The unit has proven itself to be economical and suitable for Euro 95 fuel . The standards used in the development of the device allow not only its long-term operation even in the most difficult and changeable climatic zones, but also modernization.
