两种不同喷油嘴对柴油机排烟影响的机理分析

The Mechanism Analysis for Exhaust Smoke when Two Types of Nozzle are Applied to Diesel Engine

对两种喷油嘴应用在某型柴油机上不同的烟度特性进行了分析,认为不同喷油嘴的头部结构差异使喷油嘴具有不同的喷油规律,从而影响到燃烧过程,导致不同的排烟效果。

The paper analyses the exhaust smoke density when two types of nozzle are applied to one type of diesel engine. It concludes that the difference of configuration of nozzle’s head brings on deferent fuel-injection rule and process of combustion,and results in different exhaust smoke density finally.
