Description

Automobile high energy igniter

The utility model is a kind of high-energy igniter of automobile engine starting igniting usefulness.

Traditional automotive ignition system is that the Ka Telin ignition system is to use an inductor coil, breaker point in parallel with the objective device of electricity and suitable power supply (storage battery) to form in the prior art.Each igniting only produces a spark, and ignition energy is little.As east wind car design energy 45 millijoules.Ubiquity following defective: the platinum of distributor is ablated easily, and working life is short, the easy carbon deposit of spark plug.Platinum time of closing contact weak point when high engine speeds turns round.The spark coil secondary output voltage descends, and is easy to generate at a high speed to catch fire.Some industrially developed country adopt microcomputer control to automotive ignition system, and ignition energy and working efficiency are increased substantially.But adopt microcomputer control to change to the parts in addition of whole ignition system, complex manufacturing, difficulty is big." electronic circuit complete works " volume 1 day is with the electronics electricity firearm of having reported the assembling of a kind of discrete component in the circuit, and domestic also have on probationly, but circuit is complicated, and element is many, and volume is big, and the error of each element directly affects using effect.

The purpose of this utility model is to realize high-energy ignition under the situation of the part in addition that does not change igniting system.

The utility model adds an electronic controller and realizes on original ignition system.Controller circuitry has designed transistor switching circuit and DXZD thick film integrated package.Switching circuit is made up of BG1, BG2, D1～D4, C1～C4, R1～R3, and it is big to have an output energy, and (inductance) negative cutting had the time of rising apace and descending.The DZXD integrated package is formed multi-vibrator by Q1, Q2, Rb1, Rb2, Rc1, Rc2 and R, and the base stage from the collector electrode of Q1 to Q2 is inserted emitter follower Q3, makes its output waveform more near rectangle.Small product size is little, is convenient to produce and use.

The utility model forms continuous many sparkover in the moment that platinum disconnects, and produces the multiple-spark burning.When engine speed was 3000 rev/mins, between each burn period, promptly each platinum opened moment and can form spark more than two, and each flower is suitable with traditional single spark ignition flower energy, should and improve ignition energy more than one times.After the advantage that multiple-spark is lighted is high tension spark disruptive spark plug gap, formed initial fire nuclear is its induction period when departing from the sparking-plug electrode place along with the disturbance of mixed gas, and then second, third spark is lighted and is padded on the unburned mixture at sparking-plug electrode place again, play the effect that enlarges fire nuclear and promote flame combustion, velocity of combustion is accelerated, and fuel oil fully burns.In addition, when making first spark fail to light mixed gas when the mixed gas composition variation or owing to other reason, when just catching fire, then second, third spark all can be lighted in working lipe, this makes the fire loss ratio that usually occurs on the automobile greatly reduce good reliability.This igniter can keep the secondary high pressure of equal amplitude in quite broad speed range, thereby can form and have the strong flame kernel of transmission capacity, and has overcome and sacrificed the inductive discharge time after frequency improves, and the weak phenomenon of spark can occur.This igniter ignition timing, acceleration is good, need not maintain, and the life-span is long, and oil-saving effect is remarkable, and comprehensive fuel saving ratio is stabilized in 6%, and the harmful gas that has effectively reduced HC, CO and NOX is most discharged, thereby, remarkable economic efficiency and social benefit are arranged.The utility model can be good severe cold winter starting domestic animal, is suitable for extremely frigid zones and uses.Owing to need not do any change to traditional ignition system, so controller of the present utility model can be produced separately, be installed on the single spark ignition device of existing various vehicles, also can install, for automobile industry development provides advanced technology in the unit that produces new car.
