高压共轨柴油机二次预喷射的应用

Application of Two Pilots Injection in High-pressure Common-rail Diesel Engine

提出了在高压柴油共轨系统上应用二次预喷的手段,在不牺牲动力及油耗的前提下,达到比应用一次预喷方案更低的噪声、排放及更好的低温冷起动能力,高原冷起动能力。

This paper presents application of 2 pilots injection in high-pressure commonrail diesel engine. Without sacrificing power and fuel consumption, lower noise and emissions and better cold-start in low temperature and in plateau will be reached to than that in one pilot injection.
