The device holistically demonstrates the structure and operation of the engine ignition system based on real
components of six ignition systems, including the contact-controlled ignition system, Hall electronic ignition system,
magnetic induction ignition system, photoelectric sensing ignition system, distributorless MPI ignition system, and
distributorless independent ignition system. 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.
