新型 2 2、2 8、34系列柴油机是日本新铁工所为适应目前高性能、低公害等需求而开发的新型中速柴油机。本文介绍了这些柴油机的开发方针 ,主要技术参数 ,以及曲轴、主轴承、气缸体、气缸套、气缸盖、活塞、连杆、进排气门等主要零部件的结构特点。文中还以 2 8HLX型柴油机为例 ,介绍了对其所进行的各种确认试验及试验结果。
The new 2 2,2 8,34 series diesel engine is the new Japanese high-speed iron to adapt to the current high-performance, low-pollution and other needs of the development of a new medium-speed diesel engine. This paper describes the development of these diesel engines, the main technical parameters, as well as the crankshaft, main bearing, cylinder block, cylinder liner, cylinder head, piston, connecting rod, intake and exhaust valve and other major components of the structural characteristics. In this paper, we also take the 2 8HLX diesel engine as an example to introduce the various confirmation tests and test results.
