There are many friends of the car appeared as the problem is not due to the car problem, but in many cases is caused by improper operation, such as many cases can cause poor oil filter. Excessive crankshaft sludge. During operation of the engine, high-pressure unburned gases, acid, moisture, sulfur, and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall. The metal powder produced by the wear is mixed together to form sludge.
If the air intake pipeline is dirty, if the vehicle is often driving in a road with a lot of dust and poor air quality, you should pay attention to cleaning the air intake pipe to ensure the smooth flow of the air intake. The intake pipe is very important for the normal operation of the engine. If the intake pipe is dirty, the efficiency will decrease, and the engine will not be able to operate within the normal output power range, which will aggravate engine wear and aging.
A small amount of sludge can be suspended in the oil and when it equates to a large amount, it precipitates out of the oil, clogging the filter and the oil hole, causing the engine to be difficult to lubricate, thereby aggravating engine wear. In addition, when the oil is oxidized at a high temperature, a paint film and coke deposits are formed on the piston, so that the engine oil consumption increases and the power drops. In severe cases, the piston ring is stuck and the cylinder is pulled.
