大、中型柴油机车辆在低排放、节油、舒适性及载重能力等方面的要求日益严格。与这些要求相适应,近年来的车用柴油机在小型,轻量、大功率和低油耗等方面取得了引人注目的进展,其技术背景主要是采用电子计算机技术研制了各种可变机构。其中包括进气系统、燃烧系统以及其他的可变机构。本文将介绍目前各国所采用的车用柴油机的各种可变机构及其发展动向。
Large and medium-sized diesel vehicles have become increasingly stringent in terms of low emissions, fuel efficiency, comfort and load capacity. In line with these requirements, in recent years, diesel engines for automobiles have made remarkable progress in terms of small size, light weight, high power consumption, and low fuel consumption. The technical background is mainly the development of a variety of variable mechanisms using electronic computer technology. These include intake systems, combustion systems and other variable mechanisms. This article will introduce the current various countries using a variety of automotive diesel engine variable mechanism and its development trend.
