Description
Technical field
It the utility model is related to automobile technical field, specifically gasoline natural gas double fuel engine electric-control system.
Background technology
When considering convenient supply and two aspects of energy-conserving and environment-protective, many engines wish to be operated in two kinds of fuel modes
Under：A kind of pattern is can conveniently to obtain fuel supplement, such as gasoline；Another pattern is desirable to province that can be as far as possible
Money either environmental protection, therefore, dual-purpose fuel is optimal selection.Combustion gas is used in the case of source of the gas abundance, it is nervous in source of the gas
When met an urgent need using fuel oil.It is translation formula that dual fuel system is now most popular, i.e., on the basis of engine original single-fuel
Adding a translating controller, the translating controller reads the fuel injection amount of former (gasoline) controller, then by the emitted dose (vapour
Oil) carry out the emitted dose that calculating becomes second of fuel (CNG/LNG), by second of fuel (CNG/LNG) according to calculating after
Emitted dose sprays into engine combustion acting.The system of this translation formula have ignored the difference of different fuel burning, inevitably
Task performance of the engine under second of fuel (CNG/LNG) pattern is reduced, and this structure can not support OBD
(On-BoardDiagnostics, OBD), with the continuous upgrading of national environmental protection regulation, it will be eliminated.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, there is provided reduction waste of fuel, the gasoline of disposal of pollutants are natural
Gas electric control system of dual-fuel engine.
To achieve the above object, the utility model provides following technical scheme：Gasoline natural gas double fuel engine is automatically controlled
System, including main frame ECU, fuel gas supply module, gas pressure regulator, stepping motor gas valve and engine block, fuel gas supply
Module includes source of the gas and pressure sensor, and fuel gas supply module is connected with main frame ECU, fuel gas supply module and engine block it
Between be connected with gas pressure regulator and stepping motor gas valve in turn, stepping motor gas valve and engine block with main frame ECU
It is connected, engine block includes lambda sensor, TPS, vehicle speed sensor and air flow sensor, main frame
Quantity control valve is additionally provided between ECU and engine block.
The utility model has an advantageous effect in that compared with prior art：The utility model main frame ECU passes through various biographies
Sensor gathers different pieces of information, and the gas quantity or amount of gasoline into engine are accurately controlled by stepping motor gas valve, reduces combustion
Material wastes, disposal of pollutants.

Block 2, gas pressure regulator 3, stepping motor gas valve 4 and engine block 5, fuel gas supply module 2 include source of the gas 6 and pressure sensing
Device 7, fuel gas supply module 2 are connected with main frame ECU1, and combustion gas is connected with turn between fuel gas supply module 2 and engine block 5
Voltage-stablizer 3 and stepping motor gas valve 4, stepping motor gas valve 4 and engine block 5 are connected with main frame ECU1, engine
Module 5 includes lambda sensor 8, TPS 9, vehicle speed sensor 10 and air flow sensor 11, main frame ECU1
Quantity control valve 12 is additionally provided between engine block 5.
Operation principle of the present utility model：Source of the gas 6 may include multiple fuel gas bottles, and gas pressure is detected by pressure sensor 7
Power, and real-time delivery gives main frame ECU1, main frame ECU1 to remind user's aerating in good time, lambda sensor 8, TPS 9,
Vehicle speed sensor 10 and air flow sensor 11 transmit data to main frame ECU1 in real time, and main frame ECU1 calculates according to these data
Required gas quantity, and controlled by the control of stepping motor gas valve 4 into the gas quantity of engine or by quantity control valve 12
Into the amount of gasoline of engine.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
