某款柴油机降低下排气的改进设计和应用研究

Study on Improved Design and Application of a Diesel Engine with Lower Exhaust

为降低柴油机工作时的下排气,改善产品性能并满足环保法规要求,在不改变缸径和缸心距的前提下,通过对某款柴油机采用无缸套机体设计、活塞环匹配升级、合理优化配缸间隙,实现同等条件下排气明显降低。

In order to reduce the exhaust of diesel engine,improve the product performance and meet the requirements of environmental laws and regulations,under the premise of not changing the cylinder diameter and cylinder center distance,a diesel engine is designed without cylinder liner,piston ring matching upgrade,optimize cylinder clearance reasonably,the exhaust significantly reduced under the same conditions.
