本文论述了为北京型液力传动內燃机车所设计和制造的12240Z型柴油机(缸径240毫米,行程260毫米,转速1100转/分)并针对样机试验中存在的缺点和问题,进行了研究、改进,使这一柴油机的经济性能、动力性能达到了先进水平。继而又进一步进行了强化,使持续功率由2700马力提高到3000马力,并使2700马力时的燃油消耗率达到149.5克/马力·小时,3000马力时的燃油消耗率达到152克/马力·小时,较强化前均降低了4克/马力·小时左右。本文最后还介绍了这一柴油机的磨耗数据及装车运用情况。
This paper discusses the design and manufacture of 12240Z diesel engine (cylinder diameter 240 mm, stroke 260 mm, rotation speed 1100 rpm) designed and manufactured for the Beijing hydraulic transmission diesel locomotive. The defects and problems existing in the prototype test are studied and improved , So that the economic performance of this diesel engine, power performance has reached the advanced level. This was further enhanced by increasing the continuous power from 2,700 horsepower to 3,000 horsepower and 149.5 g / hh at 2700 hp and 152 g / hh at 3000 hp, Lower than the previous 4 grams / horsepower hours. Finally, this article also introduces the wear data of this diesel engine and the loading and unloading situation.
