Abstract
The utility model discloses a natural gas-automobile oil gas transforming device, which comprises a gas automobile electronic control unit (ECU) and a fuel oil pump, wherein the water temperature signal output end and the fuel gas temperature signal output end of the gas automobile ECU are connected with the signal input end of an automatic oil cutoff controller respectively; the control output end of the automatic oil cutoff controller is connected with the control input end of the gas automobile ECU; the power supply input end of the automatic oil cutoff controller is connected with the working gear of an ignition switch K; the power supply output end of the automatic oil cutoff controller is connected with a coil of an oil pump control relay Z; and the power supply input end of a vehicle-mounted oil pump D is connected with a normally-closed contact J of the relay Z and a power supply. The natural gas-automobile oil gas transforming device has the advantages that: control over an oil path of an entire automobile and fuel gas use is realized by acquiring an ECU oil ejection signal, a rotating speed signal, an oxygen sensor signal, an oil pump control signal, a petroleum ejection signal and an ignition switch signal of the entire automobile by using the gas automobile ECU.
Description
Technical field
The utility model relates to gas-fueled vehicles, especially relates to gas-fueled vehicles oil gas conversion equipment.
Background technique
Gas-fueled vehicles more clean with respect to the fuel-engined vehicle discharging, and environmental pollution is littler, and fuel cost is low, are merely the half the of fuel vehicle.At present; Gas-fueled vehicles are oil, the free running mode switching of gas; Promptly freely switch between oil, the gas in the process of moving, power operation mode is: be the fuel oil pattern during startup, automatically switch for fuel oil, combustion gas pattern in going; Therefore, this pattern can't make the driver use combustion gas to export as power in the process of moving fully.
Summary of the invention
The utility model purpose be to provide a kind of reduction go expense, reduce the gas-fueled vehicles oil gas conversion equipment of environmental pollution.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The described gas-fueled vehicles oil gas of the utility model conversion equipment comprises gas combustion automobile computer controller and fuel pump; The water temperature signal output terminal of said gas combustion automobile computer controller is connected with the signal input part of automatic fuel cut-off during controller respectively with the fuel gas temperature signal output part; The control output end of said automatic fuel cut-off during controller is connected with the control input end of gas combustion automobile computer controller; The power input of automatic fuel cut-off during controller is connected with the work shelves of ignition switch K; The power output end of automatic fuel cut-off during controller is connected with the coil of oil pump control relay Z; Vehicle-mounted oil pump D power input is connected with power supply through the normally-closed contact J of said oil pump control relay Z.
The normally-closed contact J of said oil pump control relay Z is that the contact is opened in normally closed time-delay.
The utility model advantage is to take said gas combustion automobile computer controller (ECU) through intercepting car load ECU fuel injection signal, tach signal, oxygen sensor signal, oil pump control signal, and gasoline injection signal and ignition switch signal are realized car load oil circuit and combustion gas are used control.Combustion gas ECU converts the injection control to combustion gas to through the emulation to fuel oil ECU fuel injection quantity and injection time.Realize of the unidirectional conversion of fuel oil pattern through said automatic fuel cut-off during device simultaneously, overcome the defective that traditional natural gas automobile oil gas can freely switch to the combustion gas pattern.Gas-fueled vehicles can only use rock gas as power fuel in the process of moving, reduce operating cost.
Description of drawings
Fig. 1 is the circuit theory diagrams of the utility model.
Embodiment
As shown in Figure 1, the described gas-fueled vehicles oil gas of the utility model conversion equipment comprises gas combustion automobile computer controller 1 and fuel pump D; The water temperature signal output terminal of said gas combustion automobile computer controller 1 is connected with the signal input part of automatic fuel cut-off during controller 2 respectively with the fuel gas temperature signal output part; The control output end of said automatic fuel cut-off during controller 2 is connected with the control input end of gas combustion automobile computer controller 1; The power input of automatic fuel cut-off during controller 2 is connected with the work shelves of ignition switch K; The power output end of automatic fuel cut-off during controller 2 is connected with the coil of oil pump control relay Z; Vehicle-mounted oil pump D power input is opened contact J through the normally closed time-delay of said oil pump control relay Z and is connected with power supply.
The utility model working principle is following:
After ignition switch K got to work shelves (ON), the normally closed time-delay of said oil pump control relay Z was opened contact J and is in closed state, the oil pump proper functioning; When ignition switch is got to start; Engine start; When rotating speed surpasses 1000 rev/mins, water temperature surpasses 40 ℃, and motor is the combustion gas pattern by the fuel oil mode switching; The normally closed time-delay of oil pump control relay Z is simultaneously opened contact J and under the combustion gas pattern, is broken off, and can not switch under the oily pattern of strile-bacing through automatic fuel cut-off during device control car load and work.
Claims (2)
