Excess oxygen in various car systems can lead to sad consequences. This is especially true for the engine. It starts to run erratically, consumes too much fuel or starts badly. In the worst case, expensive repairs also threaten. The AvtoVzglyad portal tells how to avoid problems and serious financial costs.
The main difficulty is that the place where the opening is specifically formed and draws in air is not so easy to find. The first thing to pay attention to is the air duct that goes from the air filter housing to the throttle valve. Although the pipe there is corrugated and quite thick, cracks and fractures appear over time due to vibration. Visually they are not always visible.
As a result, the mass airflow sensor (MAF) is confused in the readings and the car’s “brain” overenriches the fuel mixture. Here you have increased fuel consumption and at the same time dirty nozzles with candles. Impurities will enter the engine and leave streaks on the walls of the cylinders. That is, over time, the capital is guaranteed. It is necessary to disassemble and replace the pipe as soon as possible. Fortunately, this is fairly easy to do on most machines.
And also the wrong air-fuel mixture leads to the fact that the engine begins to “struggle”, that is, troit. Such vibrations are detrimental as they reduce the resource of the drive unit and its various components. Let’s say they request replacement of the engine mount and injector sealing rings in advance. By the way, this is one of the most common places for extraction. From time to time the rings “dub”, and then there is vibration.
Next, we recommend inspecting the various vacuum hoses. For example, “Podlyanka” can enclose the hose of the adsorption valve. Then an increased fuel burner may also appear.
But the most unpleasant thing is if there is a gap in the intake pipe of the exhaust manifold. Problems in this system can also lead to serious repairs. After all, the movement of exhaust gases goes in waves, both from the engine and to the engine. A gasket, vibrocorrugation or a crack in the exhaust manifold itself can skip. In these cases, you cannot do without replacing parts, which will be quite expensive anyway.
