There are many car faults, because of which the further operation of the vehicle becomes problematic. Such errors include error of the vehicle with the number or P0171 0171. These numbers indicate peresoedinenie mixture. Reasons lean to the injector is quite diverse. First, you need to look at the state of the machine during use lean.

Signs of a poor blend

An Error is displayed on the screen of the BC. This suggests that the amount of fuel in the air / fuel mixture is much less than air. reasons to lean on the injectorThe Presence of lean manifests itself as a misfire or a delay on the sharp pressing on the gas pedal. In other cases, the engine may triple or completely stop working at idle. In addition, at the time of acceleration, vehicle jerks, and the engine sound is quite different and distinct from the sound of the motor during normal operation. The work of the power unit when using a poor mixture is not stable.

Code index of the mixture and the possible consequences

For vehicles with standard "Euro-2" or higher on the engines began to install a sensor - lambda probe. It controls the quality of the mixture. The standard established that one of the fuel have 14 parts of air. If the minimum deviation of 0.25, the onboard computer will issue an error about lean. When you receive peresoedinenie mixture to the engine there are not only the failures but also the possibility of the engine overheating. Speed set rpm is quite low. In addition, if not to the quality of diagnosis and does not eliminate the cause of education-lean, the consequences will be much worse:

  • Overheating of the power unit;
  • Burnt piston rings;
  • Burnt valves;
  • Low engine thrust;
  • Burnout pistons;
  • Increased consumption of fuel and coolant.

Causes and how to identify them

The causes of poor air-fuel mixture (injector) is quite simple and lie in the car. To define them by using the diagnostic engine. First one seen by the deposits on the plugs. lean on the injector causesAlso causes poor mixture at the injector associated with the faults in the fuel injection system. She is responsible not only for the supply of fuel to the power unit, but also for the correct preparation of the air-fuel mixture. In this case, it may be a problem with the fuel setting, or air. Because of this, and there is peresoedinenie mixture. To solve the car owner should seek professional advice, as the failure of the injection system may include faulty sensors, incorrect adjustment of the angles of the throttle. Also, it is a gathering of the firmware in the electronic control unit of the internal combustion engine. It is worth remembering that the composition of the mixture may change to some values only minimum a short time. Otherwise, you need to find the problem and fix it.

What to do in case of error

Reasons for a poor mix on the injector (2110 in particular) if they are detected, you can resolve independently, but the best solution is to drive the vehicle to a specialized workshop where mechanics will conduct a thorough diagnosis and to detect other defects in the work vehicle. To call the service station is because most drivers simply do not know how to control and configure the future air-fuel mixture. Usually on fuel injected engines and carburetor this opportunity at the car owner has. As an example, should allow the adjustment of the opening angle of the throttle. It is enough to change the position of the retaining ring, alternately moving it in the special grooves of the throttle.lean fuel mixture at the injector causes

Self-regulation

Most drivers are very happy that you know how to adjust the angle of the throttle position, as they are fully confident that with the help of this happens adjustment of fuel consumption. In addition, some resort to the firmware of the electronic control unit of the vehicle. To disable certain units or the ECU, you should seek the assistance of qualified masters who can with the help of special programs without affecting the quality of the mixture to improve some performance of the car. Otherwise, increasing the risk of “kill” the engine of your vehicle. Thus is formed a lean mixture on the injector, causes (2114 no exception) which lie in independent corner adjustment or the intervention of an inexperienced car owner in the operation of the engine.

Fuel system

Other causes of poor mixture at the injector lies in the improper operation of the fuel system of the vehicle. As a rule, disorders in the occur due to low quality fuel that is poured on a little-known gas stations. One of the options to instability and formation of lean is attributed clogged fuel elements of the car. In such cases, there is a skip in the engine. Inthe car can twitch. To avoid this, you need to purchase fuel only with the checked up gas stations. Also should be timely replacement of both fuel cells. Remember that one filter on the injector in the form of mesh and mounted directly to the fuel pump. The second element is most often near the tank on the bottom of the car, at least - in the engine compartment. To avoid peresoedinenie mixture, it is necessary to change them at intervals no less frequently than every 40 000 km. Sometimes this figure may be lower as everything depends on the quality of gasoline.

Clogged injector

If not spending time changing fuel cell vehicle systems can lead to poor blend on the injector, the reasons for which will be covered in malfunction of the injectors. That is, the fuel supplied, but served in a fairly low number. The injector is a special device belonging to the injection system of the car. There are many elements: electromagnetic, electrohydraulic or piezoceramics. On cars with petrol engines uses electromagnetic detail. reasons to lean on the injector VAZThe problem is as follows. Not on time replaced fuel filters over time, begin to miss the fuel with foreign substances, not conducting high-quality cleaning. Since the needle and nozzle of the injector holes is small enough, the incoming fuel with outsiders polluting elements form on the walls of the deposits, and so small in diameter pass fuel decreases even more. In the end, the engine is not receiving the fuel it needs and there are problems with lean.

To solve the problem, you can restore the previous injection by atomizer, which is only possible with the use of special equipment.

By the Way, to avoid contamination of fuel filters and injectors should be cleaned fuel tank with a small periodicity, as there is a large accumulation of dirt, sand or other substances.

Other causes and solutions

In the system forms a lean fuel mixture at the injector. The reasons may be different. For example, it can be formed due to the presence of air leak with a foreign objects, so you should inspect the pipes and hoses that go from the air filter for a tight seal. VAZ 2107 injector on the lean of reasonsAnother cause could be a cracked intake manifold. Eventually have to replace. The cost of this items is quite high. In addition, the air is drawn and from the sensor of the twentieth. Worth to check o-rings at the installation location.

Indeterminate reasons

In other situations, what is the car VAZ 2107 injector on the lean, the reasons for this are unknown. Carried out diagnostics indicates a failure of lean, but does not identify the cause that led to its formation. In this case, you will have to search at random - view all of the system. causes of poor air-fuel mixture injectorFirst, causes poor mixture in the injector can be caused by deposits of dirt on the connecting plugs, which prevents the quality work of the engine. Also a search should be made of suitable nozzles on the subject of pass of air. It is also necessary to rinse the injector, because due to poor gasoline on the walls inside gives a strong Nagar. lean on the injector causes 2114This article was reviewed by all the main causes that affect the education of the poor of the mixture, whereby the driver will expand your horizons and be able in some cases to make repair on their own. If you are a novice motorist, not worth it without the experience to repair, better to send the car for diagnosis to a HUNDRED. And most importantly - remember that the timely resolution of problems will increase the lifespan of your unit.
