Background technique
The enhancing of Along with people's environmental consciousness, the motor vehicle exhaust emission problem is more and more denounced by people.The diesel engine of traditional maximum discharge is faced with the destiny that is eliminated, and the enterprise of the motor of many production diesel engines has to develop low-emission diesel.In addition, domestic diesel-fuel price is progressively soaring, causes cost of transportation to improve constantly.In this case, many enterprises increase some gas combustion apparatus on the basis of original diesel engine, succeeded in developing gas engine.Gas engine is won the market against low emission, low price.But, to compare with DENG, the gas engine compression ratio reduces, and winter, fuel gas temperature was low, made the gas engine cold start-up become a difficult problem.In addition, under the situation of existing market, the quantity of Vehicle Fueling Station is also few, in case the combustion gas in the automobile uses up, interim aerating is difficulty very.
Summary of the invention
The technical problem that the utility model will solve is to overcome above-mentioned defective, and a kind of convenience, dual-purpose dual-fuel diesel engine of fuel-firing gas-firing of starting is provided.
For addressing the above problem, the technological scheme that the utility model adopted is:
A kind of dual-fuel diesel engine; Comprise diesel-engine body, cowl hood and cylinder cap; Cylinder cap is provided with intake manifold and high pressure oil rail; Intake manifold comprises main suction tude that connects air-strainer and some air intake branches that are connected with main suction tude; Be provided with high pressure fuel control valve nozzle between high pressure oil rail and the diesel-engine body, high pressure fuel control valve nozzle is connected with the diesel oil electronic management system through signal transmssion line, and it is characterized in that: said diesel-engine body is provided with gas combustion apparatus and dual-fuel control system; Gas combustion apparatus comprises combustion gas spray rail, is arranged on the gas control valve nozzle on the air intake branch, and combustion gas spray rail is communicated with the gas control valve nozzle, and gas control valve nozzle and air intake branch are one to one; Dual-fuel control system comprises double fuel EFI control centre and diesel oil/control automatically selector switch; Double fuel EFI control centre is connected through signal transmssion line with high pressure fuel control valve nozzle, gas control valve nozzle, and double fuel control centre and diesel oil electronic management system are respectively through signal transmssion line and diesel oil/control selector switch automatically to be connected.
Owing to adopted technique scheme, compared with prior art, can use two kinds of fuel of combustion gas and diesel oil in the utility model, reach the mutual conversion of fuel-firing gas-firing through the control of double fuel EFI control centre.Automobile under steam with rock gas as main fuel, a small amount of diesel oil is only as igniting or emergency.After combustion gas is used up midway, can be transformed into diesel oil, guaranteed that the utility model can not quit work because of lacking combustion gas.Utilize this complementary relationship, the cost of transportation of automobile greatly reduces, and exhaust emission reduces greatly, and is easy to use.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
