现代运输车辆用高速柴油机发展燃烧系统的目的,就是首先要满足下列三个基本要求:由低耗油量所表征的高的运用经济性,尽可能低的排气中的烟度,最后但不是最不重要的,由示功图上的低dp/da值所表征的无噪音的运行品质。为了达到这些目的,本文对实现每个目的的可能性作了一般性的考察,并且指出各种不同措施往往对耗油量、冒烟、运行品质和起动性能部分地起着互相克制的效果,因而在实践中必须兼顾不同要求的重要性而谋取一个折衷的解决方案。
The purpose of developing combustion systems for high-speed diesel engines used in modern transport vehicles is to first meet the following three basic requirements: high operational economy characterized by low fuel consumption, as low smoke smoke as possible, and last but not Most unimportant, noise-free run quality characterized by low dp / da values on the dynamometer. In order to achieve these goals, this article makes a general survey of the possibilities for achieving each of these objectives and points out that various measures often play a part in restraint of fuel consumption, smoking, operational quality and starting performance, Therefore, in practice, it is necessary to take into account the importance of different requirements and seek a compromise solution.
