The consumption of oil is to reduce the wear of various moving parts inside the engine. One of the main functions of the oil is lubrication. It is the main medium for engine lubrication. The poor lubrication will accelerate the wear of the relatively moving parts inside the engine. The consumption of oil is also necessary. Too low oil consumption can reduce the service life of the engine. However, excessive oil consumption should pay attention to whether the engine-related lubricating parts are excessively worn and accelerate the consumption of oil. The consumption of oil is not a measure of the engine. Whether the advanced parameters, the engine oil consumption of each brand engine has roughly a detection value to determine whether the oil consumption is within the normal range.

The turbocharger's floating bearing is a bearing that supports a turbine shaft that rotates at a speed of 10,000-15000 RPM (rev/min). Lubrication without lubricating oil will sinter quickly, resulting in reduced engine function until loss of function due to exhaust gas turbine increase. The pressure device is sealed by the balance pressure of the intake and exhaust. Therefore, when starting and shutting down the machine, there is always a small amount of engine oil leakage, which is also characteristic of all engines using exhaust gas turbochargers.
Engine valves and valve guides are the main components that make up the engine's gas distribution. Its working quality directly affects the performance of the engine. Its service life also directly determines the service life of the engine. The valve and valve guide are also a pair of large thermal loads. The movement pair is also lubricated by the engine oil splashing, and the lubricating oil flows into the combustion chamber to cause loss. It is a component that adjusts the amount of lubricating oil. It is not possible to seal all the lubricating oil. Otherwise, the valve and valve guide will be sintered quickly to cause damage. The effective consumption of the oil can effectively extend the life of the valve and the valve guide.
Third, cylinder liner and piston
The piston and the piston ring and the cylinder liner have the function of sealing the high-temperature gas and transmitting the combustion power of the engine, so it is necessary to have good lubrication. The main way to achieve the lubrication is the splash lubrication of the crankshaft, and secondly, the oil sprayed from the cooling nozzle is forced. Cooling and lubrication.
The piston ring of the engine has the function of "pumping oil" (the common feature of the reciprocating piston engine): the oil adhering to the cylinder wall when the piston descends is scraped off; when the piston is ascended, the oil is pumped into the combustion chamber and burned.
Fourth, the crankcase vent
In order to enable the engine to continuously output power, the crankcase must be connected to the atmosphere, so there must be a pipe to connect the crankcase and the atmosphere. Commonly known as the lower exhaust pipe, a small amount of high-temperature gas leaking through the piston ring is introduced into the atmosphere through the lower exhaust pipe. At the same time, the oil mist caused by the high-speed rotation of the crankshaft is discharged into the atmosphere, resulting in a small amount of oil loss. The position of the lower exhaust pipe is different, and the oil consumption is not uniform, but the difference is very small and can be ignored. worry. 
The engine is normally worn out under normal maintenance conditions, and improper maintenance can cause excessive engine wear. In general, the engine should be inspected and maintained. The engine should not be turned off immediately before the flameout, to prevent the supercharger from sintering, and to clean the air filter frequently.
