Abstract
The utility model discloses a distributor control type transistor automobile igniter which relates to an igniter for automobile is suitable for the bonding of a battery terminal negative pole and the ignition of an oil engine of an automobile with platinum contacts. The automobile igniter is composed by an igniting signal generator and a power amplifier with a protection circuit, wherein, the igniting signal generator comprises the platinum contact point arranged on the edge of a distributor cam and a transistor switching circuit, and an ignition coil as the load of a high power transistor is also connected with the transistor switching circuit. The utility model has the advantages of simple structure, fuel saving, long service life, etc. The average fuel consumption can be reduced about 15%-20% by the utility model.
Description
The utility model relates to a kind of ignition device for internal combustion except that ignition by compression, relates to a kind of igniter that utilizes the transistor vehicle fuel motor of distributor control or rather.
At present, vehicle fuel engine ignition device has two kinds of mechanical type and electronic types, and the mechanical type igniter mainly is made of distributor, spark coil, capacitor, ballast resistor, spark plug.The greatest drawback that this igniter exists is: in the course of the work, the low even no-spark generation of spark energy is easily ablated, easily pollutes, caused in distributor platinum contact, and rate of fault height and fuel combustion are insufficient, and energy consumption is big; Pure electronic type igniter is the non-contact electronic ignition device, the rate of lighting a fire height, but complex structure mostly, and the high and easy-maintaining not of price, spark energy is low.
The purpose of this utility model is to design a kind of contact automobile electronic igniter that has, it is a kind of transistor switching circuit device that utilizes distributor cam to rotate the control pair of contact, have simple in structure, characteristics such as cost is low, good startup, fuel-economizing, power is strong, reliable and stable, the life-span is long, be applicable to that operating voltage is 12V, the igniting of all motor vehicle fuel motors of battery terminal negative bonding, use platinum contact igniter, needn't change the former ignition system of Motor Vehicle, simple installation.
The utility model is made up of power amplifier two-part functional part of signal generator for ignition and band protective circuit.Signal generator for ignition comprises a pair of platinum contact on former distributor cam limit and the transistor switching circuit that is made of transistor, resistance etc.This contact is serially connected in the transistor base loop, and distributor cam rotates a week, make contact once, transistor turns is exported a break-make pulse signal; Power amplifier comprises switching circuit and the protective circuit thereof that is connected into by high power transistor (GTR) and resistance; spark coil is as the load of High-power Semiconductor Triode; the conducting of break-make pulse signal driving power pipe; the electric current of spark coil is undergone mutation; secondary winding induces very high voltage, by spark plug discharge sparking.
Describe technology of the present utility model in detail below in conjunction with embodiment's accompanying drawing.
Accompanying drawing 1 is a distributor controlling type transistor igniter for automobile circuit structure diagram.
Accompanying drawing 2 is a distributor controlling type transistor igniter for automobile wiring schematic diagram.
Referring to accompanying drawing 1, K is a pair of platinum contact on distributor cam limit among the figure, and L is a spark coil, and K and L are original parts of car accumulator ignition system, and A, B, C are that igniter is drawn line end, and D draws line end for the igniter ground wire.K, PNP transistor T1, resistance R 1-R3, diode D1-D3 form signal generator for ignition, control triode T1 by the break-make of distributor point K and are in conducting respectively and end two states, and this circuit adopts Current Negative Three-Point Capacitance, with stable operating point.Power supply just provides steady current for T1 to three of T1 base stage serial connection diode D1-D3.Form the power amplifier of being with protective circuit by NPN transistor T2, diode D4-D6; pulse signal to signal generator for ignition output carries out power amplification; make spark coil at secondary acquisition high pressure; the electrical spark that produces makes full combustion of fuel to quick-fried; promote engine piston motion and work, finish igniting process.The T2 base stage over the ground between the effect of diode D4 be protection triode T2 emitter junction, prevent its reverse breakdown, the effect of triode T2 emitter, collector electrode diode D5, the D6 between over the ground is that protection T2 can not punctured by instantaneous pressure.Take above protective measure, can guarantee that circuit works reliably and with long-term.Among the figure T1 base stage over the ground between the effect of reference diode DW be: one and supply voltage raise, the DW conducting, T1, T2 are in dark saturation state, do not have alternating current among the spark coil L, igniter is in flameout state automatically.R4 is the voltage-stabiliser tube current-limiting resistance.
Because the movement speed of igniter electronic switch is than the quick action of mechanical switch K, thereby the amplitude height that boosts, fast, the spark quality height of igniting response, save fuel oil, improved ignition effectiveness, make the inflammable mixture burning more abundant, improve engine output and low-temperature startup performance, also reduced exhaust emissions concentration.During work, platinum contact K only need just can trigger igniting by minimum electric current, platinum contact thereby ablation phenomenon can not occur.This igniter is through testing in various vehicles, and average consumprion descends 15%～20%, and is more obvious to the oil-saving effect of high revolution motor.
Referring to accompanying drawing 2,10 is igniter among the figure, has four to draw line end A, B, C, D, and igniter 10 is installed and fixed in position.Because this igniter is applicable to the igniting of the fuel engine of all battery terminal negative bonding vehicles, only need during installation former ignition system and lead of igniter transposing, being about to lead on the former distributor takes and removes electric capacity, this lead is connected with igniter C line end, wiring terminal on the igniter A lead-in wire termination distributor, igniter B lead end is connected on spark coil to be had on the wiring terminal of (+) mark, and D lead end bonding installs and fixes very easy.
