The utility model solves the problems that the electric injection vehicle directly injects the gas fuel and the 'ECU' of the original vehicle is utilized to carry out the injection control to the gas fuel, thus reaching the purpose of reducing the energy loss, reducing the tail gas pollution and improving the benefits.
Description
Technical field:
The utility model relates to the gaseous fuel electrospray of fuel gas electric spray car (single fuel) and gasoline-fuel gas electric spray car (dual-purpose fuel) and supplies with and automatic control tegulatingdevice.
Background technique:
In recent years, automobile just with unprecedented speed, enters among the human society in a large number.Therefore, the development clean fuel automobile is preserved the ecological environment, and regulates energy resource structure, the problem that has become the whole society and paid close attention to.At present, one of effective measures are to adopt rock gas or liquefied petroleum gas (LPG) clean fuels such as (general designation combustion gas) as automotive fuel, substitute gasoline and diesel oil.But majority is to adopt the natural aspiration mode that adds the Venturi tube mixer at intake duct in present existing technology and the product, this mode energy consumption height, waste of fuel is many, and exhaust emissions does not satisfy the exhaust index of increasingly stringent, and what have also exists tempering to blow out and blow up the problem of parts such as empty filter lid.Other has minority to adopt the spray regime air feed, but what adopt is mechanical dispensers or nozzle, its complex structure, and each cylinder tolerance is assigned error, and the rate of fault height, and tolerance is regulated and also will be joined one " ECU " again, cost is very high.
Summary of the invention:
The purpose of this utility model, provide a kind of employing electromechanical integration technology and provide gaseous fuel to motor car engine, thereby make motor in the overall process of operation, can both reach optimum Working, reduce energy consumption, the EFI car gaseous fuel electrospray of increasing the benefit is supplied with and automatic control tegulatingdevice.
The utility model is by the following technical solutions:
A kind of fuel gas electric spray car gaseous fuel electrospray is supplied with and automatic control tegulatingdevice, comprise air cylinder, pressure reducing regulator, electronic gas nozzle, electronic controller, connecting line and electric wire, air cylinder (1) is installed in the back case of automobile, pressure reducing regulator (3) is installed in the cabin of automobile, and electronic gas nozzle (4) is installed on each cylinder intake manifold of motor and links together by pneumatic tube (7) and pressure reducing regulator (3) and air cylinder (1); Electronic controller (5) is installed in the cabin of automobile and " ECU " (8) by electric wire and electronic gas nozzle (4) and former car link together.
" ECU " by former car sprays control to gaseous fuel.
Described combustion gas comprises rock gas, liquefied petroleum gas (LPG), biogas, coal gas.
The utility model has solved EFI car direct injection gaseous fuel, and utilizes " ECU " of former car that gaseous fuel is sprayed the problem of control, thereby has reached the minimizing energy consumption, reduces tail gas pollution, the purpose of increasing the benefit.
Description of drawings:
Fig. 1 is the structural representation of supply of the utility model EFI car gaseous fuel electrospray and automatic control tegulatingdevice.
Among the figure: 1 air cylinder, 2 stop valves, 3 pressure reducing regulators, 4 electronic gas nozzles, 5 electronic controllers, 6 oil-gas change-over switchs, 7 pneumatic tubes, 8 " ECU ", 9 switching controllers, 10 petrol jets.
Embodiment:
The utility model comprises parts such as air cylinder, pressure reducing regulator, electronic gas nozzle, electronic controller, connecting line, air cylinder (1) is installed in the back case of automobile, pressure reducing regulator (3) is installed in the cabin of automobile, and electronic gas nozzle (4) is installed on each cylinder intake manifold of motor and links together by pneumatic tube (7) and pressure reducing regulator (3) and air cylinder (1); Electronic controller (5) is installed in the cabin of automobile and " ECU " (8) by electric wire and electronic gas nozzle (4) and former car link together.
Combustion gas enters pressure reducing regulator (3) by air cylinder (1) by pneumatic tube (7), after reducing pressure by electronic gas nozzle (4) spray into intake manifold and and air mixing, be inhaled into engine cylinder then, burning back is outputting power externally.
The information that " ECU " (8) of former car are passed back according to each sensor of motor is determined the time for spraying and the time of fuel, and the difference of electronic controller (5) based on fuel is regulated tolerance.
During automobilism, open key, connect full car power supply, the combustion gas of air cylinder (1) the inside enters pressure reducing regulator (3) by pneumatic tube (7), the information that " ECU " (8) of automobile are passed back according to each sensor of motor, determine the time for spraying of fuel and after the time, drive electronic gas nozzle (4) work, through post-decompression combustion gas by electronic gas nozzle (4) spray into intake manifold and and air mixing, be inhaled into engine cylinder then, ignition after compression, and outputting power drives automobile running, meanwhile each sensor is with the combustion case of motor, rotating speed, the change information of load and temperature etc. feeds back to " ECU " (8) of motor, " ECU " (8) are in time adjusted the time for spraying and the time of fuel again according to these information, thereby realize dynamically control, make it in the overall process of operation, can both reach optimum Working.
Because different regions, different types of combustion gas component are variant, the amount of being supplied with during burning is different, so adopt electronic controller (5) to regulate tolerance.
This model utility also can be installed on the existing gasoline electric injection car, become gasoline-gas two-purpose fuel EFI car, with single fuel gas EFI car different is many oil-gas change-over switchs (6) and switching controller (9), oil-gas change-over switch (6) is installed in the operator cabin and links together with electric wire and switching controller (9) and electronic gas nozzle (4) and petrol jet (10), be characterized in promptly can using gas again with oil.Oil-gas change-over switch is pulled to using oily direction, oil supply system work, air supply system is closed, and automobile uses the gasoline operation, oil-gas change-over switch pulled to use the gas direction, air supply system work, oil supply system is closed, and automobile uses combustion gas to move.So just strengthened the adaptability of automobile.
