Car tuning knowledge of the automotive ignition system

1, the ignition system functions

    (1) the battery voltage is 12V, converted into ignition system requires a very high voltage, and allocated to each cylinder.

    (2) in a timely manner to ignite the mixed gas of air and fuel inside the engine cylinder.

    2, the ignition system to the requirements of

    Engine to the effective operation of the following conditions must be met:

    Enough compression ratio, and a suitable mixing ratio, accurate and powerful ignition.

    Ignition of the basic functions of the system:

    The powerful spark (1) (2) accurate ignition timing (3) durable

    3, the ignition of the basic structure of the system

    Spark plug high-voltage distributor ignition coil controller in advance device

    4, the development of the ignition system

    Traditional ignition system: platinum contacts + cam

    Electronic ignition system: + ignition signal generator

    Computer ignition system: computer control

    The structure and principles of computer ignition system

    First, the computer the ignition system has the advantage

    1, the computer ignition system according to the various engine load situation, control the optimum ignition timing, so that the engine output power, and economy, the acceleration and exhaust emissions and so reach the ideal state;

    2, but the voltage induced as the speed increases will not decrease;

    3 does not use mechanical components, there is no mechanical error generation.
