自从石油危机以来,人们对降低油耗和使用重油的要求日益强烈。这种要求甚至对小型柴油机亦不例外。本文叙述了为满足上述要求而在一台缸径为255mm、行程为270mm的新型中迷机上所进行的包括燃用双燃料的开发工作。文中详细讨论了该系列发动机的设计特点以及为获得低油耗而在试验室中所进行的各种试验。文中亦给出了各种试验结果以及所获得的包括双燃料发动机在内的各种性能。 Since the oil crisis, there has been an increasing demand for reducing fuel consumption and using heavy oil. This requirement is no exception even for small diesel engines. This paper describes the development of a dual-fuel system that includes dual-fuel combustion on a new fan with a bore of 255 mm and a travel of 270 mm to meet the above requirements. The article discusses in detail the design features of this series of engines and the various tests carried out in the laboratory to achieve low fuel consumption. The text also presents various test results and the various properties obtained, including dual-fuel engines.
