On the computer-controlled auto Electronic-Ignition System
Abstract
Automotive ignition system, through the traditional platinum contacts of the opening and closing to produce high-voltage spark, due to corrosion of platinum contacts easily, and the ignition timing on distributor centrifugal advance within the agencies and institutions to control the vacuum advance, this mechanical structure exists in the course of wear and tear problems, so that ignition timing deviation occurs, can not be achieved with the best characteristics of the engine matches the requirements, thus affecting the engine performance.
As technology advances, the human right vehicle energy saving, environmental protection, safety, comfort, convenience, and power performance have higher update requirements. Automotive ignition system also experienced a revolutionary change, from the early mechanical ignition system with contact to the non-contact transistor ignition system to the electronic control ignition system has now been developed into an advanced micro-computer controlled ignition system.
Based on the U.S. INTEL's MCS-51 series MCU micro computer-controlled ignition system that can be unofficially in a variety of speed range values to provide the necessary ignition voltage and ignition duration; at different load and speed conditions, to provide the best ignition advance angle; be able to advance to the gasoline engine ignition timing is exactly the scope of knock does not occur. Electronic ignition system is more than the average fuel savings, less air pollution. Focuses on the micro-computer controlled ignition system, operation principle, work characteristics and experimental research.
First of all, this article constitutes an overview of computer-controlled ignition system.
Secondly, this article will detail the basic computer-controlled ignition system works.
Again, this article describes the work characteristics of computer-controlled ignition system.
Finally, the paper will describe the computer-controlled ignition system of the experimental findings.
Key words: The engine ignition system, micro-computers, ignition timing, control
