日本重负荷柴油机油规格的建立与发展

The Establishment and Development of Japanese Heavy-duty Diesel Engine Oil Specifications

为适应发动机技术、环保法规和燃油经济性法规的不断发展,日本建立了JASO柴油机油规格并进行了不断升级。文章主要介绍了日本重负荷柴油机油规格的建立背景和发展历程,以及JASO DH-1、JASO DH-2、JASO DH-2F重负荷柴油机油规格的性能要求与特点,并解析了日本建立的柴油机油性能评定台架试验方法。同时,对建立符合我国汽车工业特点的柴油机油规格提出了建议。

In order to adapt the development of engine technology,environmental regulations and fuel economy regulations,JASO diesel engine oil specifications have been established and upgraded continually in Japan. In this paper,the establishment background and development process of Japanese heavy-duty diesel engine oil specifications,and performance demands and characteristics of JASO DH-1,JASO DH-2 and JASO DH-2 F heavy-duty diesel engine oil specifications are mainly introduced. Performance evaluation and bench test methods of diesel engine oil set by Japan are also analyzed. In the meantime,the suggestions to establish the diesel engine oil specifications in line with the features of domestic automobile industry are put forward.
