What is the abnormal noise of the engine of LaVida Navigation Edition?

The reasons for the abnormal sound of Volkswagen LaVida engine in Pacific Auto Network are as follows: 1, the foot glue is aging or loose, and the foot glue is the glue block between the engine and the frame. 2. The abnormal sound caused by the lack of cylinders of the engine is mainly due to the abnormal operation of one or more cylinders of the engine. 3. Abnormal noise caused by "cylinder knocking". Due to poor lubrication conditions, the piston and cylinder wall are excessively worn, which leads to the clearance fit tolerance between piston and cylinder wall beyond the normal range.

The reasons for the abnormal sound of Volkswagen LaVida engine are as follows.

1, the machine foot glue is aging or loose, and the machine foot glue is a rubber block between the engine and the frame. The function is to reduce the vibration and buffer when the engine works and fix the engine. Once these feet are aged or loose, the engine will shake and produce abnormal noise;

2. Abnormal noise caused by engine cylinder deficiency refers to the abnormal operation of one or more cylinders of the engine, which is generally characterized by obvious intermittence of exhaust gas flow discharged by the automobile, severe jitter of the exhaust pipe, and the "chug" sound or plop, plop sound of the engine can be clearly heard. This phenomenon is closely related to the failure of ignition coil;

3. "Knocking on the cylinder" is not normal. Due to poor lubrication conditions and excessive wear of piston and cylinder wall, the clearance fit tolerance between piston and cylinder wall is beyond the normal range. When the engine is running, the piston skirt collides with the cylinder wall, producing a crisp sound, which is generally obvious at idle speed or low speed.

Insufficient engine oil affects serious internal wear and abnormal noise.
