Abstract

The utility model discloses the electric controller of a gasoline engine non distributor ignition. The special connection socket 2 of the ignition signal transducer, a 12 V power source, the special wire socket 4 of the ignition coil and a high power semiconductor switch component 6 are installed inside the aluminum alloy shell 1. A radiator 3 is installed on the aluminum shell 1. The utility model realizes small structure, low cost and convenient maintenance by matching with a special non distributor ignition signal generator. Except an ignition transducer, the utility model does not need the control of special micro computer or various transducers. Under the premises of maintaining the structure of traditional ignition device, the utility model gets rid of the distributor rotor arm and the distributor cover to realize non distributor ignition. The utility model reduces the inter sectors and energy loss in the process of the transmission of the high tension current, improves the operating reliability of the whole ignition system and can meet the requirements of performance and tail gas exhaust of the gasoline engine.

Description

Petrol engine distributorless ignition electronic controller

Technical field: the utility model relates to petrol engine igniting electronic controller, particularly a kind of petrol engine distributorless ignition electronic controller.

Background technique: the petrol engine that uses at home in the prior art, except there being the minority vehicle to begin to use successively the micro-processor controlled distributorless ignition device in recent years, most still use traditional distributor ignition device that has, in this ignition mechanism, owing to need to use split fire head and distributor cap, thereby the medium tache and the energy loss of the transmission of igniting high-tension current have been increased, reduced the functional reliability of ignition mechanism, the performance of motor and the exhaust emissions of automobile have all been had certain negative effect.Use micro-processor controlled distributorless ignition device, though can overcome the above-mentioned defective of traditional ignition mechanism, the whole system complex structure, the cost costliness, the maintenance and inspection difficulty needs to use special device and instrument.

Summary of the invention: the purpose of this utility model is to provide a kind of petrol engine distributorless ignition electronic controller, it is under the constant substantially prerequisite of original traditional ignition device structure, by with the distributorless ignition signal generator auxiliary work of special use, remove split fire head and distributor cap, realize the electronic igniting controllor of distributorless ignition fully.

Formation of the present utility model: it comprises the Al-alloy casing (1) of band radiating fin (3), the special-purpose connector socket (4) of 12V power supply and spark coil group, the special-purpose connector socket (2) of fire signal sensor groups, the quantity of high-power semiconductor switch element (6) is more than one, and ignition system does not re-use split fire head and distributor cap.The quantity of the high-power semiconductor switch element (6) of inner encapsulation depends on the cylinder number of motor and the firing mode of employing, and every cylinder separated ignition of two cylinder machine and per two cylinders of four-cylinder are lighted a fire simultaneously, use two high-power semiconductor switch elements; Every cylinder separated ignition of three cylinder machines and per two cylinders of six cylinder machines are lighted a fire simultaneously, use three high-power semiconductor switch elements; Every cylinder separated ignition of four-cylinder and per two cylinders of eight cylinder machines are lighted a fire simultaneously, use four high-power semiconductor switch elements.

Compared with the prior art, the utility model is according to the cylinder number of motor and the firing mode of employing, determine required high-power semiconductor switch number of elements, the redesign peripheral circuit, cooperate by distributorless ignition signal generator with special use, just can implementation structure simple, with low cost, maintenance and inspection are convenient, except the special ignition signal generator, it does not need special computer control device and various sensor, under the constant substantially prerequisite of traditional ignition device structure, remove split fire head and distributor cap, realized distributorless ignition, reduced medium tache and energy loss in the igniting high-tension current transmission course, improved the functional reliability of whole ignition system, can satisfy the requirement of petrol engine better at aspects such as performance and exhaust emissionss.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is the plan view of Fig. 1.

Among the figure 1, Al-alloy casing, 2, the special-purpose connector socket of fire signal sensor groups, 3, radiating fin, 4, the special-purpose connector socket of 12V power supply and spark coil group, 5, mounting hole, 6, the high-power semiconductor switch element.

Embodiment: as shown in Figure 1 and Figure 2, the special-purpose connector socket (4) and the high-power semiconductor switch element (6) of special-purpose connector socket (2), 12V power supply and the spark coil group of igniting signal emitter group are installed in the following cavity of Al-alloy casing (1), radiating fin (3) is arranged on Al-alloy casing (1), and the right and left has mounting hole (5).

What high-power semiconductor switch elements (6) it determines to use according to the cylinder number of motor and the firing mode of employing (every cylinder separated ignition or two cylinders are lighted a fire simultaneously), cooperate by distributorless ignition signal generator with special use, every cylinder separated ignition of two cylinder machine and per two cylinders of four-cylinder are lighted a fire simultaneously, use two power semiconductor switch elements; Every cylinder separated ignition of three cylinder machines and per two cylinders of six cylinders are lighted a fire simultaneously, use three high-power semiconductor switch elements; Every cylinder separated ignition of four-cylinder and per two cylinders of eight cylinder machines are lighted a fire simultaneously, use four high-power semiconductor switch elements.
