It is useful for any fan of the domestic automobile industry to know the reasons why the Priora engine has 16 valves. After all, this problem is quite common. Ask any driver what the reason is, he will immediately give several options for the malfunction. And also ways to solve them. Of course, by interviewing many people you can find out all the reasons. But they still need to be checked. In addition, very often the cause of engine tripping can be several conditions at once. To ensure that the problem is resolved, you need to check all possible options. Only in this case will you get rid of this problem.
Signs of engine tripping
If the Priora’s engine starts to stall, it’s hard not to notice; the car will show the following signs of a malfunction:
- Loss of vehicle traction;
- Gases will come out of the exhaust pipe unevenly, and small pops will be heard;
- On the dashboard, the “CheckEngine” lamp will initially flash, and then remain on. The engine control unit will record an error about misfire in a certain cylinder.
- The engine will take longer to start or you will need to press the gas pedal to start the engine;
If your car shows such signs of malfunction, then most likely one of the cylinders in the car is not working.
Causes
The LADA PRIORA engine has problems with the 16 valve injector for various reasons. To find out the specifics, the motorist needs to know the design features of the power unit, as well as have some vehicle repair skills.
Lada Priora 16 valves.
So, LADA PRIORA has 16 valves and a triple engine, what could be the reasons for the effect:
- Poor quality fuel.
- Malfunction in fuel supply elements.
- Malfunction of air intake units.
- Malfunction in the ignition system.
- The problem lies in the electronic part of the car.
Why does the engine troit?
Engine trouble occurs for several reasons, and sometimes these reasons together can cause the failure of any of the cylinders.
Causes:
- Injectors;
- Spark plug;
- Ignition coils;
- Hydraulic compensators;
- valves;
- Compression;
All of the above details are ways to influence engine tripping. Let's look at each of the reasons in more detail.
Spark plug
Most often, the engine may stall due to worn spark plugs. Since spark plugs are installed in the combustion chamber and are exposed to high temperatures, they often fail, which leads to misfire in the cylinder in which the spark plug failed.
If your car has misfires, the first thing you need to do is check the spark plugs, and it is best to replace them with new ones.
Ignition coil
To provide the engine with a spark, Priora uses individual ignition coils for each cylinder, that is, the ignition coil is installed directly on the spark plug.
Since the ignition coil is made of plastic, exposed to high temperatures over time, its insulation cracks, which leads to breakdown of the insulation and leakage of the spark to the engine body. Also, at high temperatures, the coil winding can melt and short-circuit, which leads to coil failure and, consequently, misfire.
Injectors
Fuel injectors, as well as spark plugs, are installed near the combustion chamber and supply fuel through valves into the chamber. When the injector becomes dirty, the fuel supply to the combustion chamber is not supplied in the required volume or is not supplied at all, this leads to misfire.
Hydraulic compensators
In the Priora, namely the 16-valve engine, instead of shims on the valves, there are hydraulic compensators that adjust the gap between the camshaft and the valve automatically using oil pressure. With high mileage, cars have problems with the operation of this part; the hydraulic valves begin to knock and soon cannot open the valve at all, which leads to misfires in this cylinder.
valves
Sometimes it happens that the valves are to blame for engine throttling, namely, when a valve burns out, a small dimple appears in it, which allows compressed gases to pass through, which does not allow the mixture to ignite normally. For this reason, misfires may occur in the Priora engine.
Compression
With high mileage, the car engine wears out and thereby loses its compression. As in the case of valves, the gases are not compressed enough, thereby not forming a good fuel mixture.
Sensors
Engine friction can be caused by 2 sensors. One of them is the idle speed sensor. If he makes a mistake, the engine will stall when cold. After warming up everything returns to normal. The problem may also be caused by the crankshaft position sensor. Usually the problem with it is visible during diagnosis.
Conclusion
. There are many engine-related malfunctions. At the same time, even seemingly harmless ones can cause a bunch of other problems. Therefore, it is important to know all the reasons why the Priora 16-valve engine triples. This will help you quickly eliminate the problem, which significantly reduces engine life. It also brings closer the need for major repairs.
After the races, such nonsense began: at idle the car was shaking, the exhaust was dark (as if it was overflowing) BUT the check light did not light up. Fuel consumption is probably 30 liters per 100. I unscrewed the spark plugs - the carbon deposits are just crazy - the spark plugs are all black. I changed the spark plugs and installed Bosch platinum - no effect =( The engine doesn’t stall at speed, but when you sharply let off the gas, it almost stalls. The revs drop to 400-500 until you rev it up... I turned off the mass air flow sensor - a slight drop in revs for a split second - then it continues to stall. Who? what can you recommend?
PS I myself understand perfectly well that you need to go for diagnostics =) I just want to listen to advice - you never know who has had such a sore...
Troubles when pressing the gas pedal sharply
When the Priora engine stalls when the throttle is opened sharply, this indicates a breakdown of the insulation of the individual ignition coils. The IKZ has rubber seals that isolate the cap of the coil and spark plugs, thereby preserving the spark from breakdown; when this cap wears out or is damaged, the spark can go to the engine body, thus, when the gas pedal is pressed sharply, it will pierce the body, which is why the internal combustion engine will triple.
Poor quality gasoline
Troubleshooting on all VAZs can primarily occur if low-quality fuel gets into the air-fuel mixture formation system. Thus, most domestic gas stations do not have a very good reputation due to the fact that they sell fuel that does not meet the standards.
Problems with car tripping are often hidden in low-quality fuel.
So, if gasoline has already entered the system, it most likely clogged the gasoline supply system, and possibly left its mark on the spark plugs. In the worst case, what all car enthusiasts fear is burnout of the valves or piston mechanism.
Therefore, it is better to take the choice of a gas station seriously, since major engine repairs will cost more than saving on good gasoline. It is recommended to overpay a little for fuel, to regularly change fuel cells and carry out constant repairs.
Trouble the engine: why is it dangerous?
This is a rather critical phenomenon, especially if the unit begins to vibrate during acceleration.
Considering that the Lada Priora has been manufactured since 2007, there are often instances where the engine knocks like on an old car 20 years ago. This is an engine running on three cylinders. It may have the latest firmware, but if the engine of a Lada Priora car is running rough and the check light is on, then such a car will not have much life left.
Air supply
Normal air supply is the key to the formation of an air-fuel mixture and a normal combustion process. Thus, a malfunction of one or more air supply elements can lead to the engine starting to choke. These include the air filter and throttle valve.
Contamination of air elements is the reason why a car stalls..
The air filter element must be changed every 20,000 km, since after this it becomes clogged and becomes unusable.
But it is necessary to monitor the condition of the throttle valve, since it is unknown when it will become clogged and begin to cause problems. Typically, motorists clean this unit themselves, using special products or a carburetor cleaner.

that is, I changed everything but the 3rd cylinder does not work, it doesn’t happen..
1) CHECK the compression of all cylinders
2). Which spark plugs have a spark leak? If all of them do, that means only the injectors are left.
Do the cords from the injector short to ground?

If there is a misfire at idle, there may be air leaks in the intake manifold; the exhaust valve does not fit tightly, and if you listen, there should be a whistle under the valve cover. if when driving under load, misfire may occur due to a lean air-fuel mixture and the above.

correct, but air leaks affect stable idling, but should not fluctuate when accelerating

compression is everywhere. spark comes too. Here it turns out that the car runs for 10-15 seconds, then blinks. Check starts to rub the car, it rubs, the voltage disappears almost completely on the 3rd injector. if I erase the error code the machine still works for 10-15 seconds

looks like injectors...you can also measure the pressure in the fuel line, or maybe the valve is burnt out

I have already mentioned this more than once, but I think it will not be superfluous. Brother has a Kalina 1.6 8 cl, Troilus both cold and hot, it turned out that there was an air leak through the sealing rubber of the injector, changed it and how the grandmother whispered. The injectors were sweaty, one even had gasoline leaks. Perhaps your case.

I would write it. But everything...is obviously in good order. What I mean is that almost everything has been replaced.
Ignition system
One of the options for why the tripping occurred is a problem with sparking. So, failure of a spark plug or one of the high-voltage wires leads to the fact that the engine begins to stall. Therefore, it is necessary to diagnose these elements for operability.
Electronic problems can also cause tripping.
Another structural element that needs to be checked is the injector, since the problem may be hidden in this element.
Last but not least, the electronics are where faults occur. So, a problem with sensors or the electronic control unit of the power unit can cause tripping.
To carry out repair and diagnostic operations, you will need not only standard tools, but also a diagnostic laptop PC, as well as a cable connecting to the ECU - K-line.
After connection and synchronization, you can determine what errors exist, or perhaps one of the sensors responsible for the normal operation of a particular node has failed. After the repair, it is recommended to reset all accumulated errors.
