作者在分析国内外有关科技文献的基础上指出：切断气缸的最有前途的方法是同时停止气缸的供油和供气。停止气缸供油系统已有许多成品，并已用在批量生产的内燃机车发动机上，但切断供气的装置目前还处在开发和试验阶段。文内介绍了内燃机车用16чн26／26和6чн21／21型发动机用的切断供气机构，并附有该机构的结构图。
Based on the analysis of domestic and international scientific and technological literature, the author points out that the most promising way to shut off a cylinder is to stop the fuel supply and gas supply to the cylinder at the same time. There are a number of products that have been used to stop the cylinder fueling system and are already being used in mass-produced diesel locomotive engines, but the cut-off of gas supply is still under development and testing. This paper introduces the cut-off gas supply mechanism for diesel engine 16-sep26 / 26 and 6-sep21 / 21 type diesel engine with the structure of the mechanism.
