Abstract
A gasoline engine ignition system solves contradiction of the prior art existed between the ignition voltage and electric spark duration. The existing capacitance energy storage and discharge ignition system and the existing induction energy storage and discharge ignition system are respectively connected in series with a reverse high-voltage diode, and then connected in parallel to for a novel ignition system. The utility model is especially suited for igniting thin mixed gas, which meets the requirements of an energy-saving engine and has the advantages of simple structure, stability and reliability.
Description
Affiliated technical field
The utility model relates to a kind of electric ignition device of the inflammable mixture that ignites, and especially ignition energy is strong, and long-term igniting is.
Background technique
At present, petrolic igniting system, a class is a capacitance energy storage discharge type igniting system, a class is an inductive energy storage discharge type igniting system.Last class igniting mooring points ignition voltage rises fast, and voltage is higher but the arc duration is shorter; Back one class igniting mooring points ignition voltage rises slow, and it is lower that voltage is compared last class, needs system is done some technical finesses if will improve voltage, and needing increases added burden, but the arc duration is longer relatively.This two classes igniting system is strong to the needs spark energy, and the energy-saving motor of lasting long period, is difficult to finish igniting of inflammable mixture.
Summary of the invention
In order to overcome the deficiency that existing igniting is, the utility model provides a kind of igniting to be, the ignition voltage of this igniting system reaches the level of capacitance energy storage discharge type, and the electrical spark endurance surpasses the level of inductive energy storage discharge type igniting system, and need not other system on the auto electric equipment is done big technical finesse, be suitable for lighting weak mixture, satisfied the requirement of energy-saving motor.
The technological scheme that the utility model adopted is: existing capacitance energy storage discharge type igniting system and inductive energy storage discharge type igniting system are connected behind the high back voltage diode separately, be connected in parallel and form new igniting and be.When trigger signal arrived, capacitance energy storage discharge type igniting subsystem generation ignition voltage formerly, because voltage is higher, had punctured the mixed gas between sparking-plug electrode on the time, makes its ionization, and the resistance value between the ionization rear electrode is very little; Inductive energy storage discharge type igniting subsystem produces ignition voltage and slightly lags behind, and its spark coil secondary windings and sparking-plug electrode and shunt capacitance constitute underdamping RLC oscillating circuit.
The beneficial effects of the utility model are: owing to be underdamping RLC oscillating circuit, duration of oscillation is longer, and ignition arc can be kept for a long time, very easily lights mixed gas, the weak mixture that has solved energy-saving motor is difficult for lighting, or has just lighted the phenomenon of promptly being blown out by eddy current.The setting of high-voltage diode makes two igniting subsystems relatively independent, and when a certain thrashing wherein, another system still can work alone, so whole system igniting reliability height.The utility model is simple in structure, and the insulation measures of electric equipment need not extra reinforcement.
