Abstract

The utility model relates to an ignition puncher for vehicles. The utility model is applied to ignition systems of motor vehicles, such as a gasoline automobile, a natural gas automobile, etc. The utility model can cause the energy of the puncture and the ignition to be increased, the ignition spark to be reinforced, and the starting performance of the vehicles to be improved. The utility model comprises an insulating casing, and a metal fixed bottom board, wherein, the inner part of the insulating casing is provided with a high voltage capacitor; a high voltage connecting wire is arranged on the high voltage capacitor; insulating fixed fillers are arranged between the insulating casing and the capacitor.

Description

Vehicle ignition punctures device

The utility model relates to a kind of vehicle ignition that is used for motor vehicle ignition systems such as gasoline, gas-fueled vehicles and punctures device.

In the background technique, existing automotive ignition system especially in the gas-fueled vehicles ignition system perforation ignition energy less, be generally 1～2 millijoule, corresponding plug ignition spark a little less than, influence the starting of gas-fueled vehicles, sometimes need start repeatedly just can make vehicle starting, even fail to start, not only bother but also waste energy.

The purpose of this utility model has been to overcome the deficiency in the above-mentioned background technology, provides a kind of vehicle ignition to puncture device, and it can increase the perforation ignition energy, strengthens ignition spark.

For achieving the above object, the technical solution that the utility model adopts is as follows:

A kind of vehicle ignition punctures device, and its special way is: comprise insulation crust and metal fixing bottom-plate, be provided with capacitor in the insulation crust, capacitor is provided with connecting line, is the fixedly packing that insulate between insulation crust and the capacitor.

Above-mentioned condenser capacity is between 100～350 picofarads, and voltage proof can be more than 20KV.

Above-mentioned connecting line voltage proof can be more than 10KV.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the connection diagram of the utility model in automotive ignition system;

Fig. 3 is a working procedure schematic diagram of the present utility model.

Number in the figure is described as follows:

The 1-capacitor, 2-insulation crust, 3-high-pressure connection line, 4-metal fixing bottom-plate, the 5-insulation is packing fixedly, the 6-set screw, and the 7-igniting punctures device, 8-bonding, the high gland of 9-distributor, 10-distributor high pressure jack, 11-high-pressure connection line, 12-additional resistance, the 13-spark coil, 14-platinum breaker, 15-bonding, 16-spark coil high pressure jack, 17-split fire head, 18-divide the cylinder high voltage wire, the 19-spark plug, 20-bonding, 21-spark plug gap.

Below in conjunction with accompanying drawing the utility model is described in further detail: comprise insulation crust 2 and metal bonding fixing bottom-plate 4, connect with set screw 6 between insulation crust 2 and the metal bonding fixing bottom-plate 4, be provided with capacitor 1 in the insulation crust, capacitor 1 is a high-voltage capacitor, its capacity is between 100～350 picofarads, and voltage proof is more than 20KV, and capacitor 1 is provided with high-pressure connection line 3, its voltage proof is the fixedly packing 5 that insulate between insulation crust 2 and capacitor 1 more than 10KV.Referring to Fig. 2, Fig. 3, Figure 2 shows that igniting punctures the annexation of device 7 in automotive ignition system.The high-pressure connection line 3 that igniting punctures in the device 7 inserts in the distributor high pressure jack of being located on the high gland 9 of distributor 10, high-pressure connection line 11 in the distributor high pressure jack 10 is connected with spark coil 13 by spark coil high pressure jack 16, and the metal fixing bottom-plate 4 that igniting punctures device 7 places on the bonding 8.Referring to Fig. 3, spark coil 13 1 ends are connected with high-pressure connection line 11, the other end links to each other with platinum breaker 14, platinum breaker 14 places on the bonding 15, be connected with split fire head 17 on the distributor high pressure jack 10, with dividing a cylinder high voltage wire 18 to be connected, spark plug 19 places on the bonding 20 between split fire head 17 and the spark plug 19.Between spark coil 13 and power supply, be provided with additional resistance 12.During real work, when vehicle launch or the normal operation in starting back, platinum breaker 14 ceaselessly closure makes spark coil 13 energisings, disconnection makes spark coil 13 outages and produces high voltage, by high-pressure connection line 11 and high-pressure connection line 3, igniting punctures device 7 and at first part high voltage energy storage is got up, in addition, high voltage is by split fire head 17 and divide cylinder high voltage wire 18 to add high voltage on spark plug 19, when spark coil 13 voltages raise the also moment in disruptive spark plug gap 21, igniting puncture high-pressure energy that device 7 stores by high-pressure connection line 3 and split fire head 17 and divide cylinder high voltage wire 18 in the spark plug gap 15 moments emit, light mixed gas, reach the enhancing spark, increase the purpose of perforation ignition energy.

Compared with prior art, the advantage and the effect that the utlity model has are as follows:

1, the utility model makes the perforation ignition energy expand 20～40 millijoules to from existing 1～2 millijoule, Can effectively strengthen spark, increase the perforation ignition energy;

When 2, gasoline car changes gas-firing into, need with the oil starting, startability can not started with gas directly Can be good, can save natural gas during operation more than 13%, increase power more than 2.3%, have obvious society Benefit and economic benefit;

3, the utility model is simple in structure, and production cost and use cost are all lower.
