一、概述现在,国外使用微处理机控制内燃机的技术,发展非常迅速,并且收到显著的效益。这项技术,或者叫做发动机电子控制技术,其根本出发点在于实现内燃机的全面优化运行。现有内燃机的工作系统,由于其本身的结构和性能的限制,只有在设计规定的特定工况运行时性能良好。如果工况改变,工作条件及环境不同,或者长期运行发动机磨损,其工作状况将明显地变差。
I. Overview Nowadays, the technology of using microprocessors to control internal combustion engines abroad has developed very rapidly and has received significant benefits. The fundamental starting point for this technology, or engine electronic control technology, is to achieve fully optimized operation of the internal combustion engine. Existing engine operating systems, due to their inherent structural and performance limitations, perform well only in the specific operating conditions specified in the design. If the conditions change, different working conditions and the environment, or long-running engine wear and tear, its working conditions will be significantly worsened.
