It is called the distributorless ignition system, or direct ignition system. This system provides a high voltage spark at the spark plug without many of the secondary system parts. The system can provide higher voltages and does so with fewer parts to wear out. With the rapid development of computer technology and developed countries to limit emissions from vehicles and other performance requirements for the improvement of computer applications in the car - with computer control of ignition timing to form a microcomputer-controlled ignition system, as the computer has a fast response, control high precision, Take this ignition as foundation to design ,Plus a traditional ignition system and electronic ignition system, and make ignition system experiment table. When teacher use this experiment table in teaching, the students comprehends more easily, remember much deeper and the study efficiency will be significantly improved. The design specification explain the mechanical structure of ignition system and analysis the working principle and the drive route in detail. It is the main contents that the design
