单缸柴油机排放特点及控制措施

The Characteristic and Control Measures of the Single Cylinder Diesel Engine Emission

单缸柴油机的环保性能(尤其是尾气排放)达不到国家强制标准。造成这一现状的主要原因:一是整机技术水平低,尤以耗油率和排放两项指标差距甚远;二是柴油品质差(如柴油含硫量高)。据悉国家有关部门已规划,单缸柴油机排放值自2005年1月1日起必须达到欧Ⅰ标准。为此,分析了单缸柴油机排放的特点,提出了单缸柴油机排放控制的技术措施和基本原则。

the environmental protection performance of the single cylinder diesel didn`t reach national standard. The main reason is that, first, the technical level of the whole machine is low, especially the requirement gap of oil-consumption and exhaust are big; second, oil quality is bad. As we know national departments concerned had planned thet exhaust limit range of the single cylinder diesel must reach standard I of Europe since Jan.1.2005.This paper analyzed the characteristic of the single cylinder diesel engine emission, and raises the technical measures and the fundamentals of the Single cylinder diesel engine emission control.
