The device holistically demonstrates the structure and operation of the engine ignition system based on real components of six ignition systems, including the mechanically timed ignition system, hall effect electronic ignition system, magnetic trigger electronic ignition system, optical trigger electronic ignition system, distributorless ignition system(Each ignition coil servers two spark plug),distributorless ignition system(Coil-On-Plug). The device applies to theoretical teaching and maintenance training of the ignition system in secondary and senior vocational skill schools, normal education and training institutions.
