一、概述把微型机技术应用在汽车上,对于汽车产品的更新换代具有重要意义。应用微型机控制发动机的点火提前角是其中的一个重要方面。它可以提高发动机的功率,降低油耗以及减少对环境的污染。发动机的点火提前角对发动机的功率、油耗、排污以及工作平稳性等都有很大的影响,对每一种工况都存在一个最佳的点火提前角。最佳点火提前角与许多因素有关,其中最主要的是发动机的转速和负荷。当发动机负荷 First, an overview of microcomputer technology used in the car, for the replacement of automotive products is of great significance. Application of microcomputer control of the engine ignition timing is one of the important aspects. It can increase the power of the engine, reduce fuel consumption and reduce environmental pollution. The engine ignition advance angle on the engine power, fuel consumption, sewage and work stability have a great impact, there is an optimal ignition advance angle for each case. The best ignition advance angle and many factors, of which the most important thing is the engine speed and load. When the engine load
