Description
The utility model relates to diesel oil/combustion gas dual-fuel automobile air feed and control gear.
Along with the surge of automobile quantity, the atmospheric pollution that vehicle exhaust causes is serious day by day, administers the automobile tail and pollutes extremely urgent.One of effective measures are to adopt rock gas or liquefied petroleum gas (LPG) clean fuels such as (general designation combustion gas) to substitute gasoline or diesel oil.Yet, because the generally foundation of gas supply site needs time, extensively adopt original car is transformed, but make its both oil firing, can burn combustion gas again, i.e. the dual-purpose fuel car.But present existing technology and product only are applicable to the gasoline car transformation, for diesel-oil vehicle, also there are some problems in the transformation that substitutes diesel oil with combustion gas, as the at present natural aspiration mode that adds closure and Venturi tube mixed gas at intake duct, this mode complex structures of adopting of plenum system more, oil/gas shift is not steady, when using diesel oil, reduced the performance of former motor, when using combustion gas, because of the burning-point height of combustion gas, burning is difficult for fully again.
The purpose of this utility model is to adopt electromechanical integration technology, on former diesel-oil vehicle, increase by a cover electrospray air feed and a control system, keep oil supply system, thereby diesel-oil vehicle is transformed into the automotive electronics injection air feed and the control gear of diesel oil/combustion gas double fuel two-purpose car.
The utility model is by the following technical solutions:
Diesel oil/combustion gas dual-fuel automobile electrospray air feed and control gear, by air cylinder, pressure reducing regulator, fuel gas injection valve, electronic controller, the oil-gas ratin regulator, speed probe, throttle position switch, lambda sensor, tolerance shows sensor, intake manifold pressure sensor, the port timing sensor, detonation sensor, temperature transducer, oil-gas change-over switch and connecting line and electric wire are formed, air cylinder (1) is installed in the appropriate location below the diesel-oil vehicle chassis, pressure reducing regulator (3) is installed in the cabin, and fuel gas injection valve (5) is installed in suction tude (6) and upward and with pneumatic tube (4) and pressure reducing regulator (3) and air cylinder (1) links together; On QUADRANT, install oil-gas ratin regulator (10) additional, oil-gas change-over switch (16) is installed in the operator cabin, its power line is connected on the power supply key (17), output terminal is connected with electronic controller (15), the tolerance display end shows that with tolerance sensor (18) is connected, and throttle position switch (12), speed probe (13), lambda sensor (14), intake manifold pressure sensor (20), port timing sensor (21), detonation sensor (22) and the input end of temperature transducer (23) with electronic controller (15) are connected; The output terminal of electronic controller (15) is connected with pressure reducing regulator (3), fuel gas injection valve (5) and oil-gas ratin regulator (10).
The combustion gas of air cylinder (1) lining enters pressure reducing regulator (3) by pneumatic tube (4), sprays into suction tude (6) and and air mixing by fuel gas injection valve (5) after reducing pressure.Form inflammable mixture after combustion gas and the air mixing and be inhaled into cylinder, the inflammable mixture that enters cylinder provides a small amount of diesel oil (accounting for the 10-40% of former rated fuel delivery) by high-pressure service pump (9) after Piston Compression, after oil pump (8) sprays into burning, it is ignited, make its burning expansion, thereby promote the piston work done.
The information that electronic controller (15) comes according to running state and throttle position switch (12), speed probe (13), lambda sensor (14), intake manifold pressure sensor (20), port timing sensor (21), detonation sensor (22) and the temperature transducer sensor feedback such as (23) of motor is adjusted the jet amount of fuel gas injection valve (5).
Oil-gas ratin regulator (10) is regulated oil-gas ratin according to throttle position and engine operating state.
The oil-gas change-over switch (16) that is installed in the operator cabin is changed in order to realization oil gas.
Further specify the utility model below in conjunction with drawings and Examples.
Accompanying drawing is dual-fuel automobile electrospray air feed and control gear schematic representation.
Among the figure: 1 air cylinder, 2 stop valves, 3 pressure reducing regulators, 4 pneumatic tubes, 5 fuel gas injection valves, 6 suction tude, 7 air-strainer, 8 Injection Pumps, 9 high pressure oil pumps, 10 oil-gas ratin regulators, 11 gas pedals, 12 throttle position switchs, 13 speed probes, 14 lambda sensors, 15 electronic controllers, 16 oil-gas change-over switchs, 17 power supply keys, 18 tolerance show sensor, 19 motors, 20 intake manifold pressure sensors, 21 port timing sensors, 22 detonation sensor, 23 temperature transducers.
When automobile need move with pure diesel oil, oil-gas change-over switch 16 is pulled to using oily direction, air supply system quits work.
When automobile need move with double fuel, oil-gas change-over switch 16 is pulled to using the gas direction, at this moment, the combustion gas that air cylinder is 1 li enters pressure reducing regulator 3 by pneumatic tube 4, after decompression, sprays into suction tude 6 by fuel gas injection valve 5, and and air mixing.Form inflammable mixture after combustion gas and the air mixing and be inhaled into cylinder, the inflammable mixture that enters cylinder provides a small amount of diesel oil (accounting for the 10-40% of former rated fuel delivery) by high-pressure service pump 9 after Piston Compression, after oil pump 8 sprays into burning, it is ignited, make its burning expansion, thereby promote the piston work done.The information that electronic controller 15 comes according to the running state and the sensor feedback such as throttle position switch 12, speed probe 13, lambda sensor 14, intake manifold pressure sensor 20, port timing sensor 21, detonation sensor 22 and temperature transducer 23 of motor is adjusted the jet amount of fuel gas injection valve 5.Oil-gas ratin regulator 10 is regulated the fuel delivery of high pressure oil pump 9 and the jet amount of fuel gas injection valve 5 according to throttle position and engine operating state, with the adjusting oil-gas ratin, thereby satisfies the service condition of motor under various states.
