Technical Development of 2.8L Six Cylinders Supercharge Diesel Engine;

2.8L六缸增压柴油机的技术开发

Combustion gas pressures were tested experimentally both before and after supercharge.

依据实验测得增压前后的燃烧气体压力,采用扩缸前后的不同活塞设计尺寸,根据流体动力润滑与活塞动力学理论建立数学模型,使用Newton-Raphson方法求解动力学模型,使用有限差分法和超松弛迭代法(SOR)求解平均Reynolds方程,研究车用柴油机的活塞运动轨迹和横向运动速度。

The results show that the minimum lubrication oil films at the major and minor thrust sides are all diminished,and the friction force as well as friction power consumption are increased in supercharged engine.
