Description

General efficent electronic igniter

The utility model relates to a kind of general efficent electronic igniter of gasoline automobile special use.

The igniter of gasoline automobile use at present; be divided into contact and contactless two big classes are arranged; the non-contact electronic ignition device need not frequent maintenance; there are not the machinery wearing and tearing; the efficient height; but it is higher to conditional requests such as the quality of electronic component, Environmental Conditions; and general ignition all needs the spark coil of configure dedicated, special-purpose distributor or the distributor repacking of former car could be used; otherwise only play the effect of protection circuit breaker; and do not reach the purpose of fuel-economizing, thereby limited applying of ignition.

The purpose of this utility model just provides a kind of reliability height, easy to maintenance, fuel-economizing, cold appearance of vehicle is easily started, and acceleration performance is good, only increases the spark number, do not increase electric current and voltage, thereby need not the special ignition coil, need not the distributor of configure dedicated, all spendable general efficent electronic igniter on the spark coil of traditional three pillar type and two pillars.

Solution of the present utility model is such: by oscillator A, interface circuit B, prime promotes circuit C, back level power switch circuit E forms the utility model, promote to be provided with the interface circuit B that forms by transistor BG and peripheral circuit between the circuit C at oscillator A and prime, circuit breaker Kf is connected on prime and promotes circuit C, and cross-over connection has diode D between the hot junction of the collector electrode of transistor BG and circuit breaker Kf, and the negative pole of diode D is that the collector electrode with transistor BG joins.After being got above-mentioned measure, in case oscillator A gets electric starting of oscillation, the base stage of triode BG in the interface circuit is passed in the pulse of output, and triode BG is then by the frequency conducting of input pulse or end.Prime promotes the control that circuit C then is subjected to circuit breaker Kf, and when circuit breaker Kf make contact, prime promotes circuit C work, and then back level power switch circuit conducting, the energising of igniting ring formation.Open moment fully when circuit breaker Kf contact, spark coil L produces first ignition voltage, delivers on the distributor center sub, for corresponding cylinder firings work done.At this moment, open fully the contact of circuit breaker Kf, and prime promotion circuit C will quit work according to reason, and power switch circuit E ends.But because the unilateral conduction of diode D among the interface circuit B, prime promotes the base current of triode among the circuit C, the collector electrode that then can lead to triode BG by diode D, and the electric current of the current collection level of transistor BG can not lead to prime promotion circuit C and circuit breaker Kf because of the unilateral conduction of diode.With a diode D interface circuit B and prime promotion circuit C and circuit breaker Kf are separated like this, make prime promote the pulse frequency conducting that circuit C and back level power switch circuit E also just export by vibrator circuit A or end, just be formed on the interior piston of corresponding cylinder in the stroke of work done, behind first spark that spark plug is produced by circuit breaker Kf, a plurality of sparks can appear regularly, the number of its spark, then the pulse frequency by oscillator output is determined.

A plurality of sparks can be provided rather than increase electric current and voltage just because of the utility model, make mixture combustion complete, engine power increases, and oil-saving effect is obvious, because burning fully, tail gas discharging pollutant will reduce; When automobile quickened, air throttle was opened fully, and a large amount of cold mixed gass enter cylinder, and under the effect of a plurality of sparks, mixture combustion speed is fast, and speed-raising is fast, and automobile cutoff can not occur when high speed.The starting cold ratio is easier to.And just in case the ignition damage, then can utilize the circuit breaker Kf on the former car to continue to travel.

The utility model has the advantages that the reliability height, easy to maintenance, fuel-economizing, cold appearance of vehicle is easily started, and acceleration performance is good, need not special-purpose spark coil, need not the distributor of configure dedicated, and engine power increases, and tail gas discharging pollutant is few.

Accompanying drawing is embodiment of the present utility model.

Accompanying drawing 1 is an electrical schematic diagram of the present utility model.

The utility model promotes circuit C by oscillator A, interface circuit B, prime and back level power switch circuit E forms.

Interface circuit B contains transistor BG, and cross-over connection has diode D between the hot junction of the collector electrode of transistor BG and circuit breaker Kf, and the negative pole of diode D is that the collector electrode with transistor BG joins; Promoting among circuit C and the back level power switch circuit E in prime, is to adopt the mode of a plurality of transistor parallels to work, and the number of transistor parallel is optionally determined, certainly, also can adopt single transistor.

In the present embodiment, oscillator A, interface circuit B, prime promote circuit C and back level power switch circuit E is installed in the box body, its lead-in wire or leading foot and automobile circuit respective point are joined, be that lighting outlet 1 is to join with ignition switch K, lighting outlet 2 is a ground connection, lighting outlet 3 is to connect circuit breaker Kf hot junction, and lighting outlet 4 is that contact fire coil L is elementary.In addition, also can be made into modular type, draw corresponding 4 pins and the automobile circuit respective point is joined from module.
