Weak motor. Weak motor Cylinder head HR16DE

The following cars were equipped with a 1.6 liter HR16DE-Н4М engine with a capacity of 114 horsepower from Renault and Nissan (a partnership between two companies):

Nissan: Beetle, Tiida, Qashqai;

1. Renault: Duster, Megan, Fluence, Kaptur, Arcana;
2. Lada Vesta;
3. Since 2006, another modification of this engine, HR16DE-Н4Мk 1.6 liters, with a reduced power of 110 hp, has entered the market. s., with which Lada Xray is assembled.

Unlike its predecessors - the K4M and QG16DE gasoline engines, it is considered an improved engine that is free from a number of problems.

First of all, instead of a timing belt, it has a chain with a lifespan equal to the engine life and reliable ignition coils. The engine also differs in its aluminum cylinder block, which makes it lighter and QG16DE, which has a cast iron block. The engine no longer has hydraulic compensators, so valve clearances are adjusted in accordance with the operating instructions once every 88-100 thousand km. selecting the appropriate size pushers. Among other things, the engine has economical consumption and increased power, and exhaust gas emissions are environmentally cleaner (Euro 5 class). Otherwise engine everything is as usual. Production in Russia HR16DE-Н4М began on March 15, 2015 at the AvtoVAZ premises. According to reviews from motorists, the engine, with normal care, “runs” more than 250 thousand km.

Characteristics of the HR16DE-Н4М motor

Weaknesses of the HR16DE-H4M motor

• Ignition unit relay;
• Receiving pipe laying.

Ignition unit relay

Module failure is not such a rare malfunction for this motor. The engine constantly stalls. At one time, Nissan carried out a recall campaign to replace a defective unit, but it is not a fact that the work was carried out on all cars. On a car under warranty, a car service center will fix the problem free of charge.

Exhaust pipe gasket

There have been cases of burnout of the exhaust pipe gasket and, as a result, a rough exhaust sound at high speeds. Replacing the burnt gasket with a new one is the only way out of the situation.

Disadvantages of the HR16DE-H4M motor

• The generator belt whistles;
• In winter it is difficult to start;
• The engine vibrates;
• Engine jolts with a CVT variator when changing gears.

Alternator belt whistling

A fairly common problem with Nissan engines. Solved by tightening or replacing.

Hard to start in winter

In winter, at temperatures from minus 15, the engine begins to have problems with starting (it starts with great difficulty and stalls), so it is better to warm up the engine before starting. If this is easy to do in a garage, then not always in an open parking lot. This feature of the motor suggests that it was originally designed for operation in a comfortable climate.

The engine vibrates

The cause, as a rule, is a failed right engine mount. Change it and you will be happy.

Engine jolts with CVT variator during gear changes

On engines equipped with a CVT variator, gear shifting is accompanied by jolts, most likely a consequence of a manufacturing or design defect.

The presence of a small number of weaknesses and shortcomings, as well as good reviews of the engine HR16DE-H4M from car owners, confirms its reliability. It is still better to change the oil more often than recommended in the operating instructions; this will extend the service life and mileage before major repairs. The engine is suitable for partial overhaul after its service life has expired (see table), since the block does not have a sleeve; it will have to be purchased. The cheapest gasoline that can be used is 92nd, but 95th works better.

The H4M K-1 engine (HR16DE) originally belonged to Nissan, but layered policies and combinations of technologies allowed this engine to broaden its horizons. Until recently, this engine was installed on Renault Fluence, Scenic, Nissan Note, Tiida, Qashqai and many other models.
The history of the motor begins in 2006, that’s when it was put into production. It is worth noting that on different models, this engine produces different power: somewhere 114 hp, somewhere 118 hp, on the Xray, as well as on the Vesta, the power is 110 hp.

At the moment, the engine is assembled in Russia.

Motor specifications

Among the features of the motor I would like to note:

• timing chain drive (no more breaking belts)
• lack of hydraulic compensators (you will have to adjust the valves every 80 thousand km)
• Inlet phase shifter
• The engine resource is about 250 thousand km.
• 2 injectors per cylinder are installed

Tuning the H4M engine

Civil tuning for this engine is limited to the release of 4-2-1 or 4-1- without catalysts and other firmware. The maximum you can get from such an engine is around 125 horsepower. In this regard, in my opinion, the 21129 engine has much greater prospects due to the presence of tuning hardware: from pistons and camshafts to the turbo).

Nissan engine malfunctions:

At the moment it’s difficult to say anything about this engine in the VAZ version, because sales began relatively recently and the mileage of these engines is minimal. But the long history of the life of these engines on other cars can tell us something:

• Alternator belt whistling (tighten or replace belt)
• engine knocking during operation (most likely it’s time to adjust the valve clearance)
• hard to start in cold weather

The line of other engines installed on Vesta.

Good day to all! I’m writing a review about the Nissan Qashqai, and before that I drove a Nissan Primera. I agree with many reviewers who do not write about the so-called “pain of choice.” I believe that this is an individual matter and concerns the person personally. I will say one thing - initially I was aiming for a new car with high ground clearance for minimal money. Those. front-wheel drive and manual.

So, what I ended up getting: Nissan Qashqai 2013 (purchased at the end of November 2012), 5 manual transmission, 1600 cc. / 114 hp, front-wheel drive, SE equipment (it turned out that the dealer had discounts and the second equipment fit into the planned budget of 800 thousand rubles), white color.

After the purchase, I bought floor mats, window deflectors and steel protection (I didn’t buy it from a dealer). The dealer installed an alarm system and purchased a set of studded tires. By the way, either the dealer came to his senses, or something else happened, but a set of winter tires cost exactly the same as in the store. Currently the mileage is 22,000 km.

Impression

Exploitation. My thoughts about the carefree ownership of a new car were dashed within the first 500 km. It happened like this: on a frosty (-18 degrees) November evening, I decided to go for a ride. I go out to the car parked near the house. I open it with the alarm key fob. By the way, the alarm system is Sherkan 5. I get into the car. Key to start. And... disappointment!

The starter spins happily, but the engine does not catch. I have thoughts: I filled the candles. Based on the experience of owning previous cars, I do this: gas to the floor and turn the starter. The picture doesn't change. I call the dealer in the morning. He says - bring the car with a tow truck. To my question, at whose expense the serviceman answered me: at his own. If it shows that it is a warranty issue, your money will be returned. To which I tell him: damn you guessed right. We do this: the tow truck is at your expense, and then, if the diagnostics show that it’s my fault (although I sincerely didn’t understand what it was), I’ll pay for the tow truck. They agreed on this. The tow truck was supposed to arrive by lunchtime. And I decided to try to start the car again. And she treacherously wound up with half a kick.

Next, a trip to the dealer for diagnostics, which showed nothing. Literally a week later the situation repeated itself. And again the car did not wait for the tow truck to arrive and started up after an hour and a half. Here my nerves could not stand it (a new car costs 800 grand, and it starts when it wants to).

I came to the dealer, left the car for a day with the words: do what you want, but make sure it starts when I need it! And lo and behold. I don't know what they did there exactly. I was told that the engine compartment was dried for 24 hours with the intake manifold pipes removed. And it helped. At least that didn't happen anymore.

I was very pleased with the high ground clearance and the manual transmission was annoying. Before this, all cars were automatic. All two :)

Now I have become friends with mechanics and, in principle, I don’t notice them.

In the spring of 2013, there was a trip to Nizhnevartovsk (which is 2,500 thousand km one way). There are 4 people in the cabin. We drove calmly, without rushing. We spent the night in a hotel. No accidents or breakdowns. The only disappointment was the dynamics of the 1.6-liter engine with a full load (4 people + a full trunk of things). But, when purchasing, I knew what I was getting into when choosing such an engine. Mostly a car carries one person, or at most two. And in this version there is enough dynamics. Not a bullet, of course, but you can drive both on the highway and in the city.

A little about THAT. The first maintenance took place at 15,000 km, as required by regulations. Change oil and all filters. And for some reason, the dealer also has to replace spark plugs with platinum tips. I refused to replace the spark plugs, arguing that such spark plugs are designed for a longer service life than regular spark plugs. And somehow I didn’t want to pay almost 4,000 rubles for a replacement.

At the time of maintenance, the master still turned out the spark plugs. He showed them to me and said: everything is in order, you can still drive, and installed them in place. As a result, the first maintenance cost me 6 thousand and a few kopecks. It would have been a little cheaper, but they took money to remove the metal protection. They said that at the next TO-30 the spark plugs must be replaced. In principle, I am satisfied with the service from the dealer. Quickly, efficiently, everything was explained, shown, told. They were not particularly indignant at my presence in the rem. zone.

Advantages

What I like: 1. High rise. High ground clearance. 2. I also like all sorts of niceties like a rain sensor, heated seats, a radio with Bluetooth (it immediately found a common language with my phone), cruise control (this is a special delight when driving on the highway), a speed limiter and even the notorious footwell lighting for the driver and front passenger. . 3. Availability of 6 airbags + excellent rating based on crash tests. 4. Adjustment of the steering wheel and seat. I got comfortable behind the wheel. On long trips, your back and neck do not become stiff. This effect could not be achieved on previous machines. 5. Adjustable brightness of instrument lighting. 6. Headlights (headlights + foglights). 7. Suspension. Swallows holes and bumps with a bang. 8. The doors are designed in such a way that the threshold is always clean. Trousers and jeans remain clean when getting in/out of the car. 9. The lower parts of the bumpers, wheel arches and sills are hidden behind rough, unpainted plastic. Which, accordingly, protects them from stones and squeaks flying from under the wheels. And it’s not so scary to rub against the curb.

Flaws

What I don’t like: 1. The engine does not heat up at idle in winter. You sit down in a cold salon. Only heating the fifth point saves. 2. Weak engine. 3. Non-adjustable rear seat backrest tilt. On the trip to Nizhnevartovsk I had to ride in the back seat. With my height of 182 cm, I quickly get tired and every now and then various parts of my body start to feel numb. 4. Small opening angle of the trunk lid. Every now and then I hit my head when I pack something or take it out of the trunk. 5. Not the most comfortable fit on the second row of seats (small door opening angle). But this is not critical. I rarely drive behind.

Bottom line

In conclusion, I would like to say that overall I am satisfied with the car. I definitely like driving a SUV more than driving a sedan. What I expected from the car when I bought it is, in principle, what I got.

I operated the K4M on a Megane 2, and over the course of 3 years it proved itself to be a very reliable engine. Never added oil. From replacement to replacement. And it started in any frost. True, at 70 thousand I changed the phase regulator. And this is a modified engine, I think there should be no problems with it at all.

And here is what the owner of a Nissan Tiida writes about this engine. Thank you very much for the information provided. scorpii. Below is the text and photo of the author of the article:

A couple of lines about the design and service life of the HR16DE engine

The tired phrase: “the engine is the heart of the car” somehow makes you think about the health and longevity of the power unit.
I'll try to start with the design features of the HR16DE.
The prototype of the engine was the famous Renoshny K4M.
The history of the motor begins in 2004 (according to various sources), it was modernized in 2006.

Here's what Nissan writes about its HR-series engines:
“When developing the HR/MR series of engines, we have focused on maximizing efficiency. We have applied a range of technologies to reduce energy losses and increase output parameters to achieve high performance and fuel economy.
Aluminum cylinder block - allows you to speed up engine warm-up, reduce combustion energy losses due to heat, and reduce the weight of the power unit.
Technological integrated measures (structural materials + machining) minimize friction between pistons and cylinders, cams and valves and other moving parts and increase the mechanical efficiency of the engine.
To achieve greater efficiency in the use of combustion energy, we have applied new developments in gas distribution systems, fuel injectors, spark plugs and combustion chamber cooling.
To increase torque at low and medium engine speeds, we have reduced the resistance of the intake and exhaust systems and used our proprietary CVTC in the intake valve timing system."

The timing drive system uses a chain; in the HR16DE it is quite reliable (like many Nissan chain engines) and there is no need to worry about its early stretching. A constant crackling sound when the engine is running may indicate the need to replace the chain drive. Before 150-200 thousand km, symptoms of chain stretching are unlikely to appear.

There is a variable valve timing system; the phase regulator is installed on the intake camshaft. The valve clearances on the HR16DE will have to be adjusted; we don’t have hydraulic compensators. Adjustment is made once every 100 thousand km (according to some sources) by selecting pushers. High-frequency engine knocking that does not disappear when the engine warms up is the main sign of the need for such adjustment.
The phase regulator, judging by its reliable design, is designed to serve for a long time and without problems. Signs of a malfunction may include a crackling sound when starting or the impossibility of it (it starts with a bang and immediately stalls), lack of pickup when accelerating at 3500 rpm.
The aluminum cylinder block requires, first of all, compliance with the manufacturer's recommendations for servicing the cooling system: timely replacements, use of fluids according to the Nissan standard.

The design and principle of operation of the phase regulator on the HR16DE can be viewed here:

For me personally, the important point was the design of the fluid coupling itself; as we know, unsuccessful phase regulators on Renault engines often cause problems for their owners. In our case, there is no need to worry, the design is well thought out (look at the sealing inserts along both the inner and outer diameters of the coupling rotor).

So what is the engine life? Some sources on the Internet indicate a figure of 250 thousand km, based on information from the manufacturer. On various forums and clubs, there are people with about 300 thousand km on this engine without any problems. There is probably too little statistical information to draw any meaningful conclusions from these few examples.
I can assume that with timely and correct maintenance, the engine can operate for 400-500 thousand km.
1) Use recommended motor oils, taking into account, among other things, its hydraulic characteristics (durability of the chain drive and phase regulator clutch), ability to cool CPG parts (high-viscosity oils dissipate heat worse), and resistance to deposits. And remember that oil loses its properties over time, i.e. it needs to be changed in time for it to work as intended. For severe operating conditions (city), Nissan recommends 7.5 thousand km
2) Use certified antifreeze, observe replacement periods (every 60 thousand km), monitor the general condition of the cooling system.
3) Use fuel recommended by the manufacturer (95 octane), monitor the condition of the engine power system (prevention, cleaning)
4) Maintain the ignition system in good condition: do not delay replacing spark plugs, install the recommended ones.
5) Use oil filters suitable for HR16DE (do not select a filter based only on the thread size). As a preventative measure, check/change the CVTC valve filter, preventing the fluid coupling from starving (I think such a check once every 100 thousand km would not hurt). Do not forget about the role of the engine air filter and change it in a timely manner.

Maybe I forgot something, please correct me. And share your runs and recommendations.

The 2015 Renault Duster continues to gain popularity among those who prefer to purchase a passable and stylish crossover for a minimum of money. The car offers a wide range of engines, transmissions and trim levels. Today we will talk about the Renault Duster version with a 1.6-liter engine with a capacity of 114 horsepower, its features, characteristics and reviews from owners.

A little history

The 1.6 engine for Renault Duster has always been offered. But only in 2015 it found a new life and reached an unprecedented power of 114 hp. Before that, it was also a four-cylinder “aspirated” engine, which had a modest 102 horsepower and could offer low dynamic performance for such a heavy and large car.

The engine had truly high reliability and service life with a modest “appetite”, so it was very popular among Renault Duster fans. Those who did not have enough power from such an engine resorted to chip tuning and, for a lot of money, increased the power rating of the Renault Duster to 112 horsepower, to the detriment of service life and fuel consumption. By the way, gasoline with octane 95 was used, but if desired, it was possible to fill in fuel with grade 92 or even switch the Renault Duster 2015 to gas, which also added power to the engine.

The new 114 hp engine for the 2015 Renault Duster was obtained by seriously modifying the existing naturally aspirated 1.6. Moreover, not only the existing mechanisms were improved, including the piston group and the injection system, but also the software, which made it possible to “squeeze” more out of the engine without compromising its service life and fuel consumption.

The new Renault Duster engine promises even better dynamics and performance during sharp acceleration. Is this so and what numbers does the manufacturer claim?

Dry numbers

Judging by the figures provided by the manufacturer, for the new engine with 114 horsepower, compared to the old engine, almost everything has changed. On the topic of comparing the two engines, videos were posted online, detailing the difference in their design on the Duster.

As already mentioned, power increased by 12 hp, from 102 “horses” to 114. Torque also increased: if previously it was 145 Newton meters, it has now increased to a significant 156, which means that now the car will be significantly It is better to behave on sharp accelerations and uphill climbs. At the same time, as before, the 1.6 liter engine of 2015 will reach this torque value only at 4000 rpm.

Acceleration of the new Duster to “hundreds” when using high-quality gasoline, as well as when driving on dry, smooth asphalt, is 12.8 seconds.

By the way, this value has not changed compared to the old engine: the presence of 114 hp with rapid acceleration did not help matters. On the other hand, the top speed has also remained unchanged and remains a modest 160 km/h. Such a car cannot be called fast, although for a crossover this speed value is quite acceptable.

A separate conversation concerns the value of fuel consumption in various driving modes. As you would expect, the most economical for the new Renault Duster is the extra-urban cycle. Here the manufacturer promises consumption not exceeding 7.4 liters per 100 kilometers. True, as practice shows, when reaching high speeds and constantly maintaining high engine speeds, a unit with 114 hp can increase its appetite by 1-2 liters.

In a city traffic jam in a Duster, this value almost doubles and amounts to 9.3 liters per “hundred”. Moreover, in cold weather and when the air conditioner is running, this figure can also change upward. In the combined cycle, the Renault Duster 2015 promises to consume 7.4 liters per 100 kilometers, this value corresponds to driving in a small city or driving through small settlements.

Owners' opinion

Judging by the reviews, the owners recognize the new Renault Duster 2015 with a 114 hp engine as a fairly dynamic, but at the same time, economical car, perfect for transporting a large amount of luggage and traveling on light off-road terrain.

« Yaroslav. Ownership period - 6 months. I only need a car to get to the dacha and back. The main part of the route is a highway, but at the end the path lies through a bumpy road, which is replete with all sorts of bumps, slides and ruts. After watching the video and carefully studying the contents of the Renault Duster 2015, it was decided to give preference to the 114 hp engine with front-wheel drive and “mechanics”. I'm happy with the car: it drives the way it should. Consumption on average is 8 liters, but that’s because I don’t drive slowly. No damage was noticed."

Some in their reviews, on the contrary, complain about insufficient dynamics and try to solve the problem by chip tuning the Duster. " Oksana. Ownership experience - 1 year. Last 2015, I decided to replace my old Niva with a new car, more powerful and spacious. The choice fell in favor of the most modest engine in the line - 114 hp with a manual transmission. My joy knew no bounds, but that was until I was lucky enough to get on the track. When overtaking, the Renault Duster is categorically lacking in power: even in manual mode, trying to squeeze out all the juice, in half the cases it is not possible to overtake. I decided to get chip tuning: I hope this will help solve the problem.”

Also, reviews often contain recommendations that will help avoid possible mistakes during operation and save on engine repairs. " Oleg Andreevich. Ownership experience - 8 months. For me, the 1.6 engine is, if not the standard of practicality, then something close to it. Since the Duster is a work car, the mileage is quite long and alternates, either in city traffic jams or on a highway that is not of the highest quality. I can say one thing: if you change the oil according to the regulations, the engine will quickly become unusable. Based on experience, I have reduced the replacement interval to 10 thousand. But now you won’t have to drive a Duster for services, like going to work, and constantly invest money and time into the car.”

Summary

The new Renault Duster 2015 with a 1.6 engine exhibits excellent dynamics with modest fuel consumption and a long trouble-free operation life. If you change the engine oil in a timely manner, repairs will not be required soon, and the car will only be a pleasure to drive.
