Abstract
The invention discloses a contactless electronic ignition system and relates to the automatic electronic technical field, which comprises a power supply, an ignition controller, an ignition coil, a distributor, a spark plug and an ignition switch, and is characterized in that the contactless electronic ignition system comprises an ignition signal generator with the distributor, wherein the corresponding functions of the distributor are integrated on the ignition signal generator with the distributor, the ignition signal generator with the distributor is directly connected with the spark plug and the secondary winding of the ignition coil through leads, and the ignition signal generator with the distributor and the primary winding of the ignition coil are connected and controlled through the ignition controller. The contactless electronic ignition system disclosed by the invention has the advantages that the integration degree is higher, the installation is more convenient, and the ignition property of an engine at high speed is improved.
Description
Technical field
The present invention relates to technical field of automotive electronics, be specifically related to a kind of contact-less electronic ignition system.
Background technique
In recent years, motor car engine develops towards the direction of multi-cylinder, high rotating speed, high compression ratio, and people also try hard to through improving the combustion position of mixed gas, and use weak mixture, reduces exhaust pollution and fuel-efficient purpose to reach.These all require the ignition system of automobile can provide sufficiently high secondary voltage, spark energy and optimum igniting constantly.Conventional igniton system can not satisfy these requirements.
Summary of the invention
The objective of the invention is to, can not receive the restriction of contact, increase primary current, improve secondary voltage, the ignition performance when improving high engine speeds.The low-tension current of general conventional igniton system is no more than 5A, and electronic ignitin system can be brought up to 7～8A, and secondary voltage can reach 30kV.
In order to solve the problems of the technologies described above, the present invention adopts following technological scheme:
A kind of contact-less electronic ignition system; Comprise power supply, ignition controler, signal generator for ignition, spark coil, spark plug and ignition switch; It is characterized in that: be integrated with the distributor circuit on the circuit board of said signal generator for ignition; Signal generator for ignition is connected through the secondary windings of lead with spark plug, spark coil, connects control by ignition controler between the elementary winding of signal generator for ignition and spark coil; The signal generator for ignition of said band distributor receives the piston position signal of non electrical quantity and is converted into to pulse electrical signal and is transported to ignition controler.
Beneficial effect of the present invention shows:
One, because of the function with distributor is integrated into signal generator, so install the higher more aspect of level of integration;
Two, can not receive the restriction of contact, increase primary current, improve secondary voltage, improve the motor height
Ignition performance during speed, the low-tension current of generic point ignition system is no more than 5A, and electronic ignitin system can be brought up to 7～8A, secondary voltage can reach 30kV;
Three, cancelled the contact, thereby can overcome all shortcomings relevant, improved ignition performance with the contact.
Description of drawings
Fig. 1 working principle circuit diagram of the present invention.
Embodiment
To combine accompanying drawing and embodiment that the present invention is done further description below.
A kind of contact-less electronic ignition system; Comprise power supply, ignition controler, signal generator for ignition, spark coil, spark plug and ignition switch; It is characterized in that: be integrated with the distributor circuit on the circuit board of said signal generator for ignition; Signal generator for ignition is connected through the secondary windings of lead with spark plug, spark coil, connects control by ignition controler between the elementary winding of signal generator for ignition and spark coil; The signal generator for ignition of said band distributor receives the piston position signal of non electrical quantity and is converted into to pulse electrical signal and is transported to ignition controler.
In conjunction with Fig. 1, connect ignition switch, when the signal generator for ignition of being with distributor sends fire signal, when output has the positive pulse of certain amplitude, will trigger ignition controler, make pliotron conducting wherein, so the primary circuit of spark coil is connected.Primary current is by " " utmost point of the " " wiring terminal → ignition controler → bonding → power supply of elementary winding L 1 spark coil of "+" wiring terminal → spark coil of "+" utmost point → ignition switch → spark coil of power supply.Owing to have electric current to pass through in the elementary winding of spark coil,, change electric energy into magnetic field energy and store so just form magnetic field in the spark coil.The signal generator for ignition of band distributor has replaced the cam in the conventional igniton system circuit breaker; Be used for judging piston residing position in cylinder; And the piston position signal of non electrical quantity is transformed into pulse electrical signal is transported to ignition controler, thereby guarantee that spark plug is in appropriate moment igniting.So signal generator for ignition is actual is exactly a kind of perception engine working conditions, sends the sensor of fire signal.
