Lubrication System Structural Optimization and Improvement for a Certain Engine
The lubrication system is responsible for lubrication,cooling,force transmission,cleaning,seal-ing and other functions.The working state of the lubrication system is closely related to the performance and reliability of the engine.Pressure lubrication is to transport the oil through the oil channel at a suitable flow to the parts in need,to meet the oil demand of each friction pair.Taking a 4-cylinder engine as an example,the effects of oil channel structure optimization on the oil pump displacement reduction,further on the oil pump driving power reduction,thus on the improvement of the fuel economy and NVH performance of the engine are introduced.
