Igniter extension fixture discharge time
Technical field
The present invention relates to a kind of discharge control device of motor cycle ignitor, is a kind of igniter extension fixture discharge time concretely.
Background technique
The capacitor discharge type structure is all adopted in the discharge control of motorcycle CDI igniter, charging is charged to capacitor behind diode rectification, trigger signal is carried signal to controller behind rectifying and wave-filtering, controller is according to the length of trigger signal time, the in good time controllable silicon of opening, the discharge of controllable silicon conducting capacitor forms a work cycle.Though it is low that present dc point firearm (DC-CDI) has overcome the charge efficiency of early stage interchange igniter (AC-CDI), transformer in the DC-CDI has overcome the electric capacity charging fully can not saturated fully function, but the velocity of discharge of capacitor is fast, the time short, cause high pressure packet short to the firing time of spark plug, gasoline is difficult for lighting, particularly winter, temperature is low, the spark duration weak point on the spark plug cause difficult start, oil consumption is big.
Summary of the invention
The object of the present invention is to provide a kind of igniter extension fixture discharge time, make when guaranteeing former igniter function, also have the discharge time that prolongs high pressure.
The present invention realizes with following technological scheme: this a kind of igniter extension fixture discharge time structure is made up of first capacitor, first diode, resistance, first controllable silicon, second capacitor.It is characterized in that: the discharge end of first capacitor is connected with the discharge end of the 3rd capacitor, the other end is connected with first diode, first controllable silicon is connected with first diode, second capacitor, one end is connected with the 4th circuit, the other end is connected with resistance, and the resistance the other end is connected with the second silicon controlled trigger end.First circuit is connected with former car igniting charge coil, and second circuit is connected with the elementary line of former car high pressure packet, and tertiary circuit is connected with former car trigger generator, and the 4th circuit is connected with the negative pole or the car load negative line of 12V storage battery.During engine operation, the magnetogenerator rotation, the electric energy of igniting charge coil charges to the 3rd capacitor and first capacitor respectively simultaneously by the 3rd diode in first circuit and first diode, when the start pulse signal of tertiary circuit arrives, controller is opened second controllable silicon according to the time of pulse signal, the trigger signal forfeiture, meanwhile, the signal of controller also arrives the first silicon controlled trigger electrode simultaneously, but under the resistance of resistance, electric current is broken up, and first controllable silicon can't be worked, at buffer memory by second capacitor, voltage progressively raises, when reaching the first silicon controlled turning-on voltage, and the first controllable silicon conducting, the discharge of first capacitor, after having realized the discharge of the 3rd capacitor, first capacitor is discharge then, has reached to continue the function of prolongation more than 20% discharge time, thereby effectively promote engine combustion, save the function of fuel oil.
The invention has the beneficial effects as follows to have the continuous discharge time that significantly improves spark plug, make vehicle start, quicken more steady well, also have the function that reduces oil consumption, reduces exhaust emissions simultaneously.
