Д70柴油机(缸径240毫米,行程270毫米,转速1000转/分)是苏联为铁路牵引而设计的大功率中速柴油机。有关该机的选型、总体布置和主要零部件的结构,在“热力机车译丛”1967年第6期上已作过介绍。为便于广大读者批判地对该机有一系统的了解,现将该机的各系统部分及柴油机总装、调整和其在机车上的布置等逐作介绍。由于篇幅关系,分二期刊登。本期主要介绍Д70柴油机的增压系统、燃油系统、润滑系统、冷却系统和调速器控制系统等。下期将介绍Д70柴油机的组装和调整及Д70柴油机在2TЭ40内燃机车上的安装。
The Д70 diesel engine (bore 240 mm, stroke 270 mm, speed 1000 rpm) is a high-power medium-speed diesel engine designed for traction on the Soviet Union. The selection of the aircraft, the overall layout and the structure of the main components in the “heat locomotive translation Cong” No. 6 in 1967 has been introduced. In order to facilitate the readers to critically have a systematic understanding of the aircraft, the aircraft are now part of the system and the diesel engine assembly, adjustment and arrangement on the locomotive, etc. introduced. Due to the length of the relationship, published in two phases. This issue introduces the Д70 diesel engine supercharging system, fuel system, lubrication system, cooling system and governor control system. The next issue will introduce the assembly and adjustment of the Д70 diesel engine and the installation of the Д70 diesel engine on a 2TЭ40 diesel locomotive.
