Embodiment Construction
[0017] Such as figure 1 As shown, the compressed air fuel tank oil supply system described in the embodiment of the present invention includes a fuel tank 1 and an air pump 2, the air pump 2 communicates with the air inlet 3 provided on the fuel tank 1, and the fuel tank 1 is charged by the air pump 2, And then promote fuel oil output in the fuel tank 1, the oil outlet pipe 4 is connected in the fuel tank 1, and a pressure switch electromagnetic valve 5 is arranged on the oil outlet pipe 4, and the pressure switch electromagnetic valve 5 is connected with the control circuit of the air pump 2, so that When the pressure in the fuel tank 1 is lower than the lower limit value A1, the air pump 2 is started, and when the pressure in the fuel tank 1 is higher than the upper limit value A2, the air pump 2 is turned off, A2>A1>1 atmosphere.
[0018] During implementation, the pressure switch solenoid valve 5 may also be arranged on the oil tank 1 (not shown in the figure).

The invention provides a compressed-air oil tank oil supply system, which includes an oil tank and an air pump, wherein air inlets arranged in the air pump and the oil tank are communicated; the oil tank is pressurized through the air pump, so as to push the fuel oil in the oil tank to output; an oil outlet pipe is connected into the oil tank; a pressure switch electromagnetic valve is arranged on the oil outlet pipe or the oil tank; the pressure switch electromagnetic valve is connected with the control circuit of the air pump, so that when the pressure in the oil tank is lower than the lower limit value A1, the air pump is started, when the pressure in the oil tank is higher than the upper limit value A2, the air pump is closed, and the A2 is greater than A1, and A1 is greater than 1 barometric pressure. By utilizing the designed oil supply system, the problem that the fuel oil supply is not smooth as the negative pressure is easily produced by adopting the fuel pump to pump the fuel oil can be satisfactorily solved, and the problems that the engine is difficult to start and operate as the fuel oil has high viscosity during the low temperature condition of the northern winter. Due to the high pressure existing inside the oil tank, the fuel oil can be more smoothly transferred.
Description
technical field [0001] The invention relates to an oil supply system of an automobile fuel tank, especially suitable for a methanol fuel tank. Background technique [0002] The fuel supply of existing automobile engines mostly uses fuel pumps to pump fuel into the oil circuit of the engine. Since the fuel tank itself is a closed structure, when there is less fuel left in the fuel tank, a negative pressure will be generated inside the fuel tank, so that it will not It is beneficial to the smooth oil supply of the oil circuit. [0003] In winter in the north, the temperature is low and the viscosity of the fuel is high, so the requirements for the fuel pump are higher. Once the power of the fuel pump is not enough to pump the high-viscosity fuel into the engine oil circuit, the entire engine will be damaged. Difficult to start or run. Contents of the invention [0004] The purpose of the present invention is to solve the problem that negative pressure is easy to be generat...
