Electronic control and multi-turn ignition system of automobile engine (internal combustion engine)

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an electronic control and multi-cycle ignition device of an automobile engine (internal combustion engine).;The ignition device of an automobile engine which is generally used adjusts the ignition position according to the speed and temperature of the engine so that only one ignition is performed. In the case of incomplete ignition, the ignition device is incompletely combusted, It causes vibration, noise, and exhaust of sulfur dioxide in the vehicle.;For the purpose of solving such a problem, a multi-spark ignition device is known from Patent Publication No. 92-5735,_hSince the time is short and the time for the current to flow in the primary coil is short, it affects the secondary discharge voltage and t_hAnd there is a problem that the pulse generator has a minimum spark interval of 0.15 ms when 15,000 pulses are applied for 1 minute, and the function of the coefficient can be performed from 1 to 10 times, but the excessive spark count is rather limited to the ignition delay There is a drawback that the energy of dance after time is increased, and there is also a problem in controlling the variable resistance of the pulse generating circuit.;The present invention has been made to solve the above problems,_hThe limit for the time is that the ignition device with the fast response speed is adopted, so that the current flowing through the primary coil_hSo that the secondary discharge voltage is not affected even in a short period of time of 10 microseconds and the pulse of 15,000 pulses for one minute becomes 250 pulses for 1 second and the period of the pulses becomes 4 ms so that the spark interval becomes 4 ms, , It is possible to generate a pulse of 500 Hz to 100,000 Hz for 1 second in consideration of the difficulty in operation when it is high and to increase the energy of dance after the ignition delay time rather than the excessive spark frequency, And an ignition period is extracted using a value inputted from the sensor so that the energy can be controlled by varying the ignition period and the ignition period. Apparatus, with its ignition period in the range of 0.1 ms to 26.67 ms, and the multiple-count ignition frequency in the range of 1 Hz to 100 Hz And one will be available to the ignition time, the number of output signals of the two lighting frequencies individually or by multiplying the output of one of these two signals.
