Abstract
Description
technical field
[0001] The invention relates to the field of automotive electronics, in particular to a contact type electronic ignition system. Background technique
[0002] In recent years, automobile engines are developing toward multi-cylinder, high speed, and high compression ratio. People also try to reduce exhaust pollution and save fuel by improving the combustion condition of the mixture and burning the lean mixture. All of these require that the ignition system of the car can provide sufficiently high secondary voltage, spark energy and optimal ignition time. Traditional ignition systems can no longer meet these requirements. the Contents of the invention
[0003] In view of the above-mentioned prior art, the purpose of the present invention is to enable the ignition system to provide sufficiently high secondary voltage and spark energy, while avoiding the thermal run phenomenon of the device.
[0004] In order to solve the above technical problems, the presen...

Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0015] A contact-type electronic ignition system, including a power supply, an ignition switch, a distributor, an ignition coil primary coil, an ignition coil secondary coil, and a spark plug, is characterized in that it also includes a ballast resistor connected between the ignition switch and the ignition coil primary coil In the primary coil circuit of the ignition coil, an ignition control circuit composed of a triode VT, a resistor and a capacitor is added, and the contacts of the breaker are connected in series in the base circuit of the triode to control the conduction and cut-off of the triode.
[0016] When the ignition switch SW is turned on, when the breaker contact is closed, the base circuit of the triode is connected, making the triode saturated and conducting, and the primary circuit of the ignition coil is connected. The current...
