应用微机技术,使汽油机在非爆震区根据发动机的转速和功率由开环控制系统自动寻找点火角度;而在爆震区,则由闭环控制系统对其跟踪调整,至微爆状态。这样,发动机在稳态和瞬态运行都能实现点火系统的最佳控制。本文介绍的正是这种技术在480型汽油机上应用的成果。 Application of microcomputer technology, the gasoline engine in the non-detonation zone according to the engine speed and power by the open-loop control system automatically look for ignition angle; in the detonation zone, the closed-loop control system to track its adjustment to the micro-explosion state. In this way, the engine can achieve optimal control of the ignition system both in steady-state and transient operation. This paper describes the application of this technology on the 480 gasoline engine.
