特种车用柴油机降低散热量的对策

The Strategy of Reducing Heat Rejection for Special Vehicle Diesel Engine

本文指出低散热发动机对于特种车辆的重大意义．介绍了国内外研究低散热发动机的概况，剖析了V903-60O柴油机实现低散热的途径．指出降低散热量的两大对策是提高效率和对燃烧室零件隔热．文章还对一台功率883kW柴油机降低散热量做了一些设想和估算，并建议重视对高温摩擦问题的研究．

This paper describes that it is very important to reducc heat rejection for the special vehiclediesel engine and the research works over the world. Analyzing how to realize the target about V903-600 type diesel engine,the author shows two paths for reducing heat rejection: improving engineefficency and isulating heat from components around combustion chamber. The paper also presents some ideas to get low heat rejection for a 883 kW diesel engine, and suggeststo pay attention for research work about friction under the high temperature operating condition.
