Abstract

The utility model relates to an electronic wind sparking plug with three-core discharge, belonging to an igniting device for an internal combustion engine. The purpose of the utility model is to pose a sparking plug which has energy saving and high efficiency and an igniting transformer, and the sparking plug has electronic-wind flame leading. The sparking plug uses a three-discharge plug core to replace the original single plug core, using a third electronic-wind leading pole to replacing the original single flame leading pole; the three high-voltage primary and secondary stages of a transformer to replace the original single high-voltage primary and secondary stages. The sparking plug has simple structure, low cost, high efficiency, energy saving and fast starting; the utility model can normally work under the situations of cold weather or mouth flooding due to excess oil absorption.

Description

Three cores discharge electron wind spark plug

The utility model belongs to ignition device for internal combustion.

At present, ignition device for internal combustion is by ignition switch, ignition coil, circuit breaker, compositions such as spark plug.Ignition coil becomes 1～20,000 volt of above igniting high pressure to 12 volts low-voltage, makes spark plug produce strong spark, with the gaseous mixture in the ignition engine cylinder.And existing spark plug list core (see figure 1) discharges cranking internal combustion engine by the single high voltage secondary of transformer, and is cold as the sky, spark excessively a little less than, starting difficulty; When the gasoline soakage is big, mouth fire extinguishing phenomenon also appears flooding, and starting is difficult for, and because of the excessive over-emitting black exhaust of insufficient oil consumption that burns.Therefore the spark plug utmost point is waited to improve.

The utility model purpose is to propose energy-conservation, that efficent electronic wind is led flame spark plug and ignition transformer thereof.

The utility model purpose is achieved in that

A kind of three cores discharge electron wind spark plug by discharge plug core, draw the flame utmost point, insulation porcelain knob and cock body and forms, is characterized in that filling in cores 1, electron wind by three discharges guides the step-up transformer B of the utmost point 2, cavity cap 5 and three high voltage secondary into and form; Three discharge plug cores 1 with porcelain tube or plastic or other material mutual insulating, pack into the insulation porcelain knob 3 in, insulation porcelain knob 3 is outer to be installed three electron wind of standing far apart facing each other with three discharge plug cores and bending on the top in and guides the utmost point 2 into, the spark cock body 4 of guiding the utmost point 2 and metal into is integral, and same material, three discharge plug cores, 1 other end links to each other with three high voltage secondary of step-up transformer B respectively with three sockets and exterior insulation cavity cap 4 are arranged.

In conjunction with the accompanying drawings, further specify the utility model content.

Spark plug configuration figure before Fig. 1, the utility model;

Fig. 2, the utility model structure chart.

Identifier is as follows among the figure:

1, three discharge plug cores 2, electron wind are guided the utmost point 3, insulation porcelain knob 4, spark cock body into

5, cavity cap 6, draw flame utmost point B, step-up transformer LF, ignition coil LD, trigger winding SCR, controllable silicon C1-C3, electric capacity D1-D3, diode

Fig. 2 is the utility model structure chart.Three straight dotted lines among the figure in the spark cock body are represented three discharge plug cores, and dashed rectangle is an electronic circuit.

Three core discharge electronic air sparking plugs are guided the utmost point 2, insulation porcelain knob 3, height into by three discharge plug cores 1, electron wind The step-up transformer B of pressure cap 5 and three high voltage secondary forms; Three discharges with porcelain tube or plastic or other material mutual insulating The plug core 1 pack into the insulation porcelain knob 3 in, replace former single plug core; Insulation porcelain knob 3 outer installations and three discharge plug cores are far away Three curved electron wind are guided the utmost point 2 into relatively and on the top in, and the spark cock body 4 of guiding the utmost point 2 and metal into is integral, and Same material. The three discharge plug core other ends are with three sockets and exterior insulation cavity cap 4, respectively with the transformation of boosting Three high voltage secondary of device B link to each other.

Operation principle:

LF provides charging current by ignition coil, charges simultaneously for after diode D1 rectification capacitor C 1, C2, C3; When charging voltage reaches the controllable silicon SCR conducting, if trigger winding LD has signal, then make the SCR admittance, electric capacity C1, C2, C3 discharge simultaneously, and three high voltage secondary of step-up transformer are exported respectively 1-2 ten thousand above high pressure, make three Discharge plug core 1 electrion; And the top electron wind of standing far apart facing each other to guide the utmost point 2 into fond of gossip along spark with discharge spark Plug axially forward; So combustible gas is accurately lighted. No matter a day cold or oily suction is too much flooded mouth, can both be normal Operation. Because electron wind is guided three of the utmost point 1 symmetries into, and most advanced and sophisticated footpath is inwardly curved, forms electric field forward, can With the discharge spark electron wind that forms forward vertically fond of gossip.

The utility model advantage:

1, igniting long flame vectored injection, igniting are accurately started fast, energy-conservation.

2, being fit to internal combustion engine such as all motor vehicles uses.

Embodiment

Capacitor C 1, C2, C3 select for use under 0.8 μ, three elementary 50 circles that are of transformer B, and three secondary 2000 circles that are are packaged as a whole transformer and other components and parts by dashed rectangle.Three discharge plug cores 1 are φ 1mm, and insulation porcelain knob 3 internal diameters are φ 2.5mm, and electron wind is drawn the utmost point with high 9mm, stand like the legs of a tripod, and most advanced and sophisticated footpath are inwardly curved.

Claims

1, a kind of three cores discharge electron wind spark plug by discharge plug core, draw the flame utmost point, insulation porcelain knob and cock body and forms, is characterized in that filling in cores 1, electron wind by three discharges guides the step-up transformer B of the utmost point 2, cavity cap 5 and three high voltage secondary into and form; Three discharge plug cores 1 with porcelain tube or plastic or other material mutual insulating, pack into the insulation porcelain knob 3 in, insulation porcelain knob 3 is outer to be installed three electron wind of standing far apart facing each other with three discharge plug cores and bending on the top in and guides the utmost point 2 into, the spark cock body 4 of guiding the utmost point 2 and metal into is integral, and same material, three discharge plug cores, 1 other end links to each other with three high voltage secondary of step-up transformer B respectively with three sockets and exterior insulation cavity cap 4 are arranged.
