The utility model is characterized in that an electric igniter is arranged between the distributor and the ignition coil; the electric igniter is composed of a pulse generator which is composed of a triode and a diode and a power amplifier which is composed of a triode and a diode. Having the advantages of energy saving and good starting performance, the utility model can reduce air pollution, increase power performance, etc.
Description
The utility model belongs to the petrol engine electronic ignition device.
Automotive electronic igniter all adopts single igniting mechanism at present.Be that a firing pulse is only supplied with in every cylinder combustion gas, so can not guarantee fully to light combustion gas; When starting, the temperature difference is big especially, and thermal capacitance is big, and the single igniting is difficult to start vehicle, and burning is also insufficient, so starting performance is not good enough, oil consumption and pollutant emission index are all higher.
The purpose of this utility model provides a kind of orderly multiple pulse at the problems referred to above exactly, and quasi-continuous state igniting realizes the multiple spot combustion mechanism on time domain, light thereby reach easily, and fully burning reduces oil consumption, improves power, reduces the effect of blowdown.
The purpose of this utility model is to realize like this.Promptly between former automobile distributor controlled and spark coil, set up an ignition.The correct timed ignition signal that ignition provides distributor, through the controlled orderly pulse oscillator of forming by triode and diode, export orderly high-frequency ignition pulse, the power amplifier of forming via triode and diode is amplified again, and boost by spark coil, combustion gas is lighted in the spark plug discharge.
Like this, light intensity for combustion gas and average energy obviously increases.And high tension ignition pulse loss of voltage in transmission obviously reduces, thereby combustion gas is very easily lighted, and it is very abundant to burn.To realize above-mentioned purpose of the present utility model.
Advantage of the present utility model:
1. the saving energy:
Owing to adopt multiple pulse, igniting continuously, on time domain, realize a kind of so new igniting mechanism of multiple spot burning, thereby raising ignition energy, and prolong and put discharge time, not only can guarantee reliably catching fire under high compression ratio and the starting cold situation, and can make the mixed gas burning fully, burning is fully utilized; Thereby reach the purpose of saving the energy.
2. starting performance is good:
Owing to adopt multiple pulse, igniting continuously realizes the multiple spot burning on time domain, a kind of so new igniting mechanism, thus improve ignition energy, and prolong discharge time, can guarantee reliably catching fire under high compression ratio and the starting cold situation.
3. reduce pollution of atmosphere:
Owing to adopt multiple pulse, igniting continuously realizes a kind of so new igniting mechanism of multiple spot burning on time domain, make combustion gas be able to abundant burning, and the exhaust emissions index reduces, and wherein hydrocarbons content descends about 30%, reduces air environmental pollution like this.
4. power performance increases
Owing to adopt multiple pulse, igniting continuously realizes a kind of so new igniting mechanism of multiple spot burning on time domain, combustion gas is fully burnt, and fuel is fully utilized, and can make automobile dynamic quality increase about 20%.
