摘要
介绍了天然气发动机的总体设计原则;对WD615增压柴油机进气系统及燃烧系统进行了改进;确定了采用缸外预混合稀薄混合气燃烧模式以及前馈控制与闭环反馈控制相结合的控制方式;设计了电控多点顺序喷射燃料供给系统。
In this paper, the designing principle of a CNG engine is introduced. The inlet system and the combustion system of WD615 turbocharged engine are improved. A lean-burning mode in which gas is mixed outside of the cylinder and a close-loop control mode combined with open-loop are confirmed. In addition, the electronic controlled, sequence port injection system is designed.
