Abstract
As the basic means of transportation for people to travel in modern society, the scientific and technological development level of automobile is also more and more rapid. The level of automotive electronic technology has made greater and greater progress in the development process of recent decades. The design of ignition system is closely related to the driving power of vehicle. Ignition system is an important part of gasoline engine, which has a decisive impact on the performance of the engine. With the continuous development of automobile industry and the continuous improvement of automobile electronization, the automobile ignition system has developed from the traditional battery ignition system to the electronic ignition system widely used at home and abroad. The electronic ignition system is also known as semiconductor ignition system or transistor ignition system. More and more automobile manufacturers have applied electronic technology to automobiles
This paper mainly designs an automobile ignition system. The main contents include the scheme demonstration, principle description and structural design of each part of the automobile ignition system. It also includes the design concept of ignition system, the development trend of ignition system, the principle and analysis of ignition system, etc.
This paper hopes that through the design of automobile ignition system, the designer can master the knowledge of this major, integrate the theoretical knowledge into the design of actual parts system, and master the process and steps of system design.
