What is the carbon deposit in Volkswagen Ling Du engine?

The carbon deposit in Volkswagen Ling Du engine of Pacific Auto Network is mainly caused by poor fuel quality, aging of valve oil seals and front and rear crankshaft oil seals, clogged air filters and oil filters, and unclean throttle. Causes of engine jitter in Ling Du: It may be that the engine has serious carbon deposition; Ignition system failure; Aging of engine parts; Jitter caused by unstable oil pressure, etc.

The engine oil combustion of Volkswagen Ling Du is mainly caused by poor fuel quality, aging of valve oil seals and front and rear crankshaft oil seals, clogged air filters and oil filters, and unclean throttle.

First, the most fundamental reason is that the quality of the fuel we usually add is not good, and it is easy to form a large amount of carbon deposits in the combustion chamber. Carbon deposition will accelerate the wear between the piston and the cylinder wall, resulting in excessive clearance and oil flowing into the combustion chamber.

Second, the valve oil seal and the front and rear crankshaft oil seals are aging, and the seal is not strict, resulting in oil leakage.

Third, the air filter and oil filter are blocked. If the air filter is blocked, the air inlet will be blocked, the pressure will drop, and the oil will be sucked into the combustion chamber.

Fourth, the throttle is dirty. There are many and complicated reasons why the engine burns engine oil, but it is not the automobile that burns engine oil, so the engine has an "incurable disease". Now many auto repair shops can solve this problem, provided that the situation is found and will be repaired immediately. If the engine burning oil has not been repaired for a long time, it is likely to be an engine overhaul.
