Description

Automitive electronic economizer

The utility model is the automotive electronics fuel economizer that is used for the automobile gasoline machine.Belong to the petrol engine ignition control device.It is applicable to that 2～8 cylinders have all kinds of gasoline automobiles of the negative ground connection in contact.

On March 16th, 1988 disclosed Chinese patent CN86.2.09283U, name is called " automobile igniter ", both adopted transistor switching circuit and energy release circuit are set, control ignition transformer coil discharging energy discharges, to realize that improving ignition voltage improves the engine ignition performance.The present invention has not only adopted more excellent transistor switching circuit of effect and energy release circuit, and is provided with anti-interference, time-delay, indicating circuit, has improved the engine ignition performance and has improved oil-saving effect significantly with further, and realized the benefit of multiple function.

One object of the present invention provides a kind of petrol engine firing circuit of novelty, and with the big raising of former spark coil high-voltage pulse TV university, the mixed gas with in the strong high-voltage spark point gas cylinder makes its sufficient combustion, reaches fuel-economizing and reduces the purpose of discharging.

Another object of the present invention is provided with proper circuit and makes it work as that the driver is stopped or check circuit when not closing ignition switch and this device is cut off the electricity supply automatically, protects this device and ignition transformer coil not to be damaged.Working indicating also is set simultaneously with comprehensive this device of indication working condition, to reach further protection.

Above-mentioned purpose realizes in the following way:

(a) anti-jamming circuit (1) is set: it comprises diode D ₁, D ₂, the inductance L capacitor C ₁, C ₂, resistance R ₁(b) delay switch circuit (3) is set: comprise triode T ₁, T ₂, diode D ₃Capacitor C ₄, resistance R ₂, R ₃(c) transistor switching circuit (4) is set: comprise triode T ₃, T ₄, resistance R ₄, R ₅And diode D ₄(d) working indicating (5) is set: comprise diode D ₅, D ₆(luminous) capacitor C ₅, resistance R ₆, R ₇(D wherein ₅, C ₅, R ₇Constitute simultaneously and discharge widely different road)

Below in conjunction with accompanying drawing the present invention is further described.

Accompanying drawing: automotive electronics fuel economizer principle and circuti diagram.

See accompanying drawing, when this fuel economizer was not installed, original device had: 1. mechanical switching circuit (2): it comprises the distributor point K switch ₂And capacitor C ₃2. ignition transformer D (primary air N ₁(low pressure), secondary winding N ₂(high pressure)) and additional resistance R _D3. petrol engine spark plug LD.If be unkitted fuel economizer, the direct and low voltage side N of mechanical switching circuit (2) ₁The distributor point K switch was connected ₂Frequent alternately make and break makes transformer D high pressure side coil N ₂Produce high-voltage pulse current, with light up plug LD.

See figure, this fuel economizer has been installed after, when motor moves, ignition switch K ₁Closure, contact switch K ₂Alternately make and break is worked as K ₂During disconnection, positive source passes through resistance R ₁, diode D ₃To capacitor C ₄Charging, during to certain voltage, triode T ₁, T ₂Conducting.Work as K ₂When closed, because R ₁R ₂R ₃Bias triode T ₃Conducting is along with making triode T ₄Conducting.Flow through ignition transformer D primary air N thereby produce ₁Exciting current I.Work as K switch ₂During disconnection, triode T ₃Be cut off, along with T ₄Also be cut off, flow through primary air N just thereby cut off ₁Exciting current I.At K ₂Disconnect moment, primary air N ₁The 1/2L of middle storage _DI ²(L _DBe N ₁Self-induction) potential energy is through diode D ₅, capacitor C ₅, resistance R ₇, R ₆, light emitting diode D ₆The widely different road of forming of release (5) discharges rapidly, because in the circuit of the present invention, K switch ₂The exciting current of setting up before the disconnection is bigger, therefore works as K ₂After the disconnection, flow through elementary winding N ₁Electric current sharply descend by a very big electric current, make secondary winding N ₂Generate very high induced electromotive force, thereby formed very high ignition voltage and very big ignition energy.

See figure, this fuel economizer is provided with anti-jamming circuit (1): the High-frequency Interference ripple that produces when circuit imports economizer circuit into by inductance L by positive pole, diode D ₁, D ₂, capacitor C ₂, C ₃Stop, eliminate.

Work as parking of automobile, motor stops operating, and the driver should disconnect the igniting K switch ₁, disconnect K if forget ₁, but because of contact switch K ₂Remain closure after the shutdown, then capacitor C ₄Discharge is by triode T ₁T ₂, resistance R ₂, K switch ₂To zero potential, ground wire, back T has discharged ₁, T ₂Become by conducting and to end, along with T ₃, T ₄End, make T ₁T ₂T ₃T ₄N ₁Automatically cut off the power supply with anti-tamper Deng element.When starting working again after to stall, K switch then ₂Replace make and break thereupon.At K ₂During disconnection, power supply still passes through R ₁D ₃To C ₄Charging, when reaching certain voltage, T ₁, T ₂Conducting, T subsequently ₃, T ₄Conducting and K ₂Synchronous working.

See figure, the working indicating (5) that this fuel economizer is provided with: as previously mentioned, work as K ₂Disconnect moment, N ₁Pass through D ₅, C ₅, R ₇Release energy simultaneously, to capacitor C ₅Charging, the back capacitor C of having charged ₅Pass through resistance R ₆, light emitting diode D ₆, coil N ₁, resistance R _D, straight positive source forms the widely different road of discharge to negative pole, makes light emitting diode D ₆Luminous, working properly with the indication fuel economizer.Otherwise, if internal damage, N are arranged ₁There is not energy to discharge, then C ₅Do not discharge D ₆Not luminous.
