Engine lubricant oil cooling, lubrication, cleaning, sealing has four big functions, its to ensure the normal work of engine play a crucial role.With the increase of engine working time, engine oil due to the high temperature oxidation and wear of mechanical parts, fuel steam corrosion and the influence of such factors as contamination.In addition, the engine oil also has certain consumption in normal use.
So we are going to have to periodically check the oil level and the degree of polluted, that is why we want to change oil regularly.
If the oil is lower than the specified value and influence to the engine work, then the fatal damage the engine.Below we specific to discuss the reason of the oil consumption and how to avoid the terrible consequences.Under normal operation of the oil will be consumed, from sense absolutely no oil consumption of engine doesn't exist.The reasons are as follows:
1, oil for lubrication of piston, piston ring and cylinder, when the piston moves downward, will leave a layer of oil film in the cylinder wall. Vehicle deceleration, generate high negative pressure will be some of the oil suction chamber, the engine oil and oil film part in the cylinder wall, by high temperature combustion gas combustion in the process of combustion.
2, oil for lubrication is also into the valve stem, drawn into the combustion chamber.High temperature of waste gas will also be burning oil for lubricating the exhaust valve.
The following are factors that affect oil consumption:
1, oil viscosity, the oil viscosity is lower, the sealing effect is poorer, the more the amount drawn into the combustion chamber.
2, vehicle driving conditions: high speed and frequent acceleration and deceleration, will increase the consumption of oil.
3, in the process of high speed, dilute the composition will evaporate, so will find excessive oil consumption after high speed.
4, due to the new engine without running in, so will consume more oil.
Finally recommends the longest once every 1000 km to check the oil level, if the conditions allow the best in every time they go for inspection.
