Many Owners of the VAZ 2112 are faced with the fact that there are sixteen of them valve motor started to tremble. The causes of this effect are typical for all injection-type engines. The fault is to be found in three places: air or fuel supply, as well as a spark generation unit. But, it also happens that electronics affect the operation of the engine.
Causes
General view of the engine 21124 16V.
Troit engine VAZ 2112 injector 16 valves according to different reasons. To find out the specifics, the motorist needs to know design features power unit, as well as have some vehicle repair skills.
So, VAZ 2112 16 valves troit the engine, what could be the reasons for the effect:
- Poor quality fuel.
- Malfunction in the fuel supply elements.
- Violation of the air intake units.
- Malfunction in the ignition system.
- The problem lies in the electronic part of the car.
Solution Methods
Before starting the process of analyzing the causes in more detail, as well as troubleshooting methods, it is worth understanding that if the motorist is not sure that he can fix the breakdown or does not correctly diagnose, then it is better not to climb yourself. IN this case it is recommended to contact a professional car service.
Poor quality gasoline
Poor quality fuel everywhere.
Tripping on a VAZ can primarily occur if the education system air-fuel mixture poor quality fuel. So, most domestic gas stations do not have quite good reputation due to the fact that they sell fuel that does not meet the standards.
So, if gasoline has already entered the system, then, most likely, it clogged the gasoline supply system, and possibly left its mark on the spark plugs. In the worst case, what all motorists fear is the burning of valves or a piston mechanism.
Therefore, to choose filling station better to be taken seriously overhaul engine will cost more than the savings on good gasoline. It is recommended to overpay a little for fuel, which should be changed regularly fuel cells and make ongoing repairs.
fuel cells
The process of replacing clogged fuel filter.
The first place to look for a problem is the fuel supply to the fuel mixture formation system. Thus, contamination of elements can cause not enough fuel that enters the combustion chambers.
First you need to check the functionality fuel pump, or rather such an element as a mesh filter. It is located on the pump itself and often becomes clogged due to the use low-quality fuel. But, it is worth changing it, and the operation of the power unit returns to normal.
It is recommended to replace the fuel filter together with the filter screen of the gasoline pump, since in this case it becomes clogged and the fuel cannot fully pass through the fuel lines. The part is located under the rear right wheel from the bottom side. The element is changed within 30 minutes.
Do-it-yourself injector cleaning process.
The third element, which is responsible for supplying the fuel mixture, are the injectors. Their clogging and leads to the fact that the motor begins to troit. In order to check their performance, it is necessary to dismantle the elements from the engine. Diagnostic operations are carried out on a special washing stand. If during the check it was found that there are faulty injectors, then they should be replaced. You should not install faulty parts in the power unit, as this will lead back to tripling and more big faults than the existing ones.
air supply
Troit engine may due to problems with the air filter.
Normal air supply is the key to the formation of an air-fuel mixture and a normal combustion process. So, a malfunction of one or more elements of the air supply can cause the engine to start to choke. These include air filter and throttle valve.
The air filter element must be changed every 20,000 km, because after that it becomes clogged and becomes unusable. But for the state throttle valve must be monitored, because it is not known when it will clog and begin to bring problems. Usually, motorists clean this unit on their own, with the help of special means or carburetor cleaners.
Ignition system
One of the options for why tripling occurred is a problem with sparking. So, the failure of a spark plug or one of high voltage wires causes the engine to stall. Therefore, it is necessary to diagnose these elements for performance.
Soot on candles means a malfunction of the motor and the causes of tripling.
Another structural element that needs to be checked is the injector, since the problem may be hiding in this element.
Electronics problem
Last but not least, the source of faults is electronics. So, the problem is with the sensors or the electronic control unit power unit may cause tripping.
To carry out repair and diagnostic operations, you will need not only standard tools, but also a diagnostic portable PC, as well as a cable for connecting to the computer - K-line. After connecting and synchronizing, you can determine what errors exist, and perhaps one of the sensors responsible for normal work one node or another. After the repair, it is recommended to reset all accumulated errors.
Conclusion
The causes and methods for eliminating the malfunction of tripling on the VAZ 2112 16 valves are considered. If the problem still cannot be removed, then it is recommended to contact a car service so that professionals can figure it out. Maybe it's time to replace the valves or rebuild the engine.
What could be the reasons?
Hello! My engine has recently started shaking. At the same time, he Troit just constantly. I do not know where to look, what to repair! Please tell me.
There may be several reasons for the fact that interruptions occur during engine operation. And the case when the engine runs on three instead of four cylinders cannot be confused with anything. And his "rattling" soon makes car owners think about speedy repairs.
The following two tabs change content below.
All my life I was surrounded by cars! First, in the village, already in the first class, I was running around on a tractor through the fields, then there was JAVA, after a penny. Now I am a third-year student at the "Polytechnic" at the Faculty of Automobiles. I work part-time as a car mechanic, helping to repair cars to all my friends.
The video below shows in detail the symptoms when the engine troit:
What threatens "triple"?
When the engine is running on three of the four cylinders, not only does it decrease, there is excessive fuel consumption, from exhaust system it turns out, the trembling and trembling of the engine just makes it difficult to feel comfortable inside the car. However, the troubles don't end there.
When one cylinder is not functioning, non-burning fuel accumulates in it, which flows down into the crankcase with oil, which in turn liquefies, becomes less viscous. As a result, all its lubricating properties can be lost, which can lead to piston and ring wear, creating scuffing on the cylinder walls. It is not difficult to guess that engine tripping can lead to its overhaul.
Possible reasons
In most cases, when the cylinder does not work, the culprit is one of the elements of the ignition system, which is responsible for igniting the fuel, or the injectors responsible for supplying fuel.
Check the ignition system in the following order:
If there is “smoky” or strong soot on the candle, this prevents it from stable work, . Few, it is necessary to find the cause of this phenomenon. Check if is correct for .
Dirty candle, with an oily trail.
It is best to check the candle for a spark on a special stand, or on your own.
For self check put the high-voltage wire on the spark plug, and put its body on the engine (the electrode should not touch it - approx.), then, with an assistant, scroll the starter. So a spark should appear on the candle.
Also pay attention
If a spark does not appear when checking the candle, or it is very weak, it may indicate the following problems:
- The high voltage wiring needs to be replaced.
- Need diagnostics for electronic block management.
- The timing belt has shifted a few teeth due to. How .
Remember that for the best and most thorough check and the cause of engine tripping, you can find out by doing engine diagnostics.
For experienced and novice motorists, any breakdown or malfunction in the car causes extremely negative emotions. Especially when you need to go to work early in the morning and the car does not start well and starts troiting.
There are a lot of reasons for such engine operation, so we will try to reveal the most frequent malfunctions when the VAZ 2112 engine starts to triple.
Ignition module failure:
The module creates switching directly for each cylinder and then transfers voltage to high voltage wires according to the operating cycle of the engine. The failure of this element can lead someone to what the machine will build. On average, the resource of this node rarely exceeds 200 thousand kilometers, so if the car is not new, it is better to change it in advance.
High spark plug wear
Spark plugs must be changed in accordance with the regulations Maintenance. (Nickel candles run an average of 20-45 thousand km, iridium and platinum 50-100 thousand km.)
Breaking high voltage wire
High-voltage wires or as they are also called "armored wires" transmit electricity to the spark plugs from the ignition module. Working in conditions high voltage and the strength of the current disables the conductor, and sometimes the outer sheath of the wire, which creates a voltage drop or the complete absence of it. Apart from this in engine compartment going on constant differential temperatures, fuel and lubricants getting on the wire sheath, which can lead to its delamination and scorching.
valve burnout
Modern gasoline engines are highly accelerated power plants. Remember 20-30 years ago, 100 hp was hardly removed from a 3-5 liter engine, this had to be achieved with great difficulty. Including installation of an injector and an increase in the number of valves per cylinder. As a result high temperatures, and sometimes Low quality fuel, the valve may burn out. It breaks down and stops functioning, eventually fuel mixture ceases to fully flow into the cylinder, and the exhaust does not come out back.
Litter and dirt in fuel injectors
Cars of the VAZ 2110 family are equipped with a distributed injection system. injection injection includes 4 injectors per cylinder. A clogged one of them can lead to the fact that the engine will not run smoothly, the dynamics will drop and the speed will be difficult to gain. With such a malfunction, the engine often overheats. In advanced cases, the catalyst may burn out.
