What Cause Air Intake Hose Leakage

In the last piece, we learn the bad influence caused by air intake hose broken. From the influence we also learned the importance of air intake hose. This time let’s talk about what cause air intake hose leakage.

Because air intake hose connect the air filter and restrictor, the hose influence the engine greatly. The air intake hose made from plastic or rubber will wear by heating, vibration and moisture for long time. Then the wear cause the leakage. This is a common problem in cars, especially the older cars and the cars without maintenance for long time.

Besides, incorrect installation will cause air intake hose broken or leaked. Thus change the broken or leaked air intake hose is very important to the engine and even the car.

What will the air intake hose leakage cause?

The air charge model of the engine is a very important module in the engine calibration, and the intake air volume determines the fuel injection volume of the engine. One of the parameters in the charging model is the manifold pressure. If the manifold leaks, the most intuitive impact is that the manifold pressure measurement is biased, which in turn affects the calculation of the intake air volume and the amount of fuel injection.

If the leakage pressure on divided manifold is a numeric value, that will be fine. But if the value is higher sometimes or lower sometimes, fuel-injection quantity will be different. Thus the mixed air could be rare or dense. If it’s rare, the oxynitride will be higher in the tail gas. While if it’s dense, the carbon oxide will be more.

Besides, the leakage will cause high idling and shake. Therefore you should check your air intake hose regularly to guarantee it works well.
