Description

Overhead type high-energy high voltage package for natural gas engine

Technical field

A kind of high voltage package of automobile engine electric injection system is the utility model is related to, is especially applicable the vapour of gas fuel Car engine.

Background technology

Diesel oil is played very important with the main traffic means of transport that lorry is today's society in people's daily life Effect.Domestic production diesel oil is still engine using diesel oil as single-fuel with lorry at present, continuous with crude oil price Go up, the exhaust emissions of automobile requires more and more higher.The whole world constantly replaces gasoline using natural aerodynamic force more and more Single-fuel is applied to automobile power fuel.With the continuous expansion in market, urgent need wants one kind to can be used in natural aerodynamic force The high-energy high voltage package of igniting.Because the burning of natural gas needs bigger energy to can be only achieved stable igniting.Original use It can not meet the igniting requirement that diesel oil changes natural gas engine in the high voltage package of gasoline single-fuel.Therefore one kind is needed to meet The lorry of natural gas fired high-performance high voltage package.

Traditional dry-type high-voltage pack arrangement is as shown in figure 1, its drawback is：1. needing the connection of high-voltage line 5 could realize Igniting, energy pass through the transmission of high-voltage line 5 so that energy loss is big, and larger electromagnetic interference be present, causes igniting unstable It is fixed；Mutual inductance effect is produced 2. traditional dry-type high-voltage bag is made up of multiple windings, between them, influence each other its surrounding space magnetic The change of field, increases its magnetic resistance, reduces ignition energy；3. traditional dry-type high-voltage bag is responsible for lighting a fire to several cylinders, as long as Wherein 1 coil damage will result in whole high voltage package and scrap；4. the packing colloid of traditional dry-type high-voltage bag, enamel covered wire consume Amount is big, increases the replacement cost of user, causes the wasting of resources.

Utility model content

In order to solve above-mentioned drawback, technical problem to be solved in the utility model is to provide one kind and is exclusively used in natural gas The automobile engine high pressure bag of igniting, it is low to reduce energy loss, rational in infrastructure, good pressure-resistant performance, cost.In order to solve above-mentioned skill Art problem, the technical solution adopted in the utility model are, for the overhead type high-energy high voltage package of natural gas engine, its feature It is, using split type mechanism, each cylinder of engine sets an independent high voltage package, and each high voltage package exists including device The Low-voltage socket and mounting hole of high-low pressure winding and iron core, device outside shell in shell；High-low pressure winding input connects Low-voltage socket, high-low pressure winding output end connection high-head；The high-head device is defeated in one end of rubber sleeve inner chamber, spark plug Enter the other end that end set is inserted in rubber sleeve inner chamber, high-head connects spark plug input by power spring.

The beneficial effects of the utility model are：1. not using high-voltage line, the spark plug being connected in cylinder body is inserted directly into On, direct-fire, reduce energy loss；2. it is compact-sized, will be small than conventional coil volume, raw material can be saved, are such as painted Copper-clad line and packing colloid, cost is small, reduces the waste of resource；3. the overhead type high voltage package of single winding, can be efficiently reduced Magnetic resistance, ignition energy is improved, reduce engine interior carbon distribution；4. due to being overhead type high voltage package that single winding is formed, coil The resistance to pressure born is stronger.And traditional dry-type high-voltage bag is often because high voltage, coil are easily breakdown；5. high pressure winding is set (top-type) is put on engine top, can prevent high voltage package high voltage package caused by the overheat that works from damaging；6. day can be met by having The high voltage of right gas igniting, the overhead type high voltage package of high-energy.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
