为了改进柴油机低温起动性能(起动、热车、冒白烟、排臭味等),本文介绍一种新的二次排气式工作过程。 在影响着火性的一些重要的因素中,最重要的是压缩温度,但是,压缩温度主要决定于压缩前的温度和压缩比。如图1所示,使压缩前的温度稍稍上升,就能使着火性得到显著改进。 In order to improve the starting performance of low-temperature diesel engine (starting, hot car, white smoke, odor emissions, etc.), this article describes a new secondary exhaust type of work process. Among the important factors that affect ignitability, the most important is the compression temperature, however, the compression temperature depends mainly on the temperature and the compression ratio before compression. As shown in Fig. 1, a slight improvement in ignitability can be achieved by slightly increasing the temperature before compression.
