本文介绍了6ЧН21/21型柴油机的气缸切断系统控制原理;指出更换配气推杆、在高压油泵喷油口上安装供油切断机构,便可构成切断指定气缸的控制系统,从而可根据柴油机的工作工况选择最佳的工作缸数。并得出结论,用切断气缸的方法可改善6ЧН21/21型内燃机车柴油机的运用经济性。
This paper introduces the control principle of the cylinder cut-off system of 6ЧН21 / 21 diesel engine. It is pointed out that the replacement of the gas distribution pushrod and the installation of fuel cut-off mechanism on the injection port of high pressure oil pump can constitute the control system for cutting off the designated cylinder, Working conditions choose the best number of work cylinder. And concluded that the method can be used to cut off the cylinder 6ЧН21 / 21 diesel locomotive economy of use.
