Embodiment Construction

[0028] Please refer to Figure 1 to Figure 11 , the fuel injection device in the figure includes a liquid infusion pipe 1, a vaporization pipe preheating mechanism, a combustion mechanism, a fan 10, a temperature sensor 11, and a controller 12.

[0029] The delivery pipe 1 guides the liquid fuel from the fuel tank 5 into the drip tray 3 through the first delivery valve 2 under the action of an oil pump. The liquid fuel is liquid alcohol or light hydrocarbon fuel, which fuel to choose depends on the needs, preferably liquid alcohol fuel such as denatured alcohol.

[0030] The vaporization pipe preheating mechanism includes an oil delivery valve 2 , a drip tray 3 and an igniter 4 . The oil delivery valve 2 not only has a switch function, but also has a function of controlling the input flow, which is also called a flow meter or other names. The oil transfer valve 2 has a liquid inlet 21 and a liquid outlet 22, the liquid inlet 21 and the liquid outlet 22 are connected with the...

Abstract

The invention discloses a fuel injection device. The fuel injection device comprises a liquid conveying pipe communicating with a fuel source, a vaporization pipe preheating mechanism, a combustion mechanism and a fan. The vaporization pipe preheating mechanism comprises an oil delivery valve, a drip tray and an igniter. The oil delivery valve communicates with the liquid conveying pipe, the drip tray is fixed to the tail end of the oil conveying pipe, and an ignition head of the igniter is located in the corresponding position above the drip tray. The combustion mechanism comprises a vaporization pipe, a nozzle and a spray pipe. The vaporization pipe is fixed the corresponding position behind the spray pipe in the air supply direction and above the drip tray. The technical problems how to preheat the vaporization pipe through fuel and pressurize gaseous fuel through the spray pipe so as to improve the injection effect of the injection device can be solved through the fuel injection device.

Description

technical field [0001] The invention relates to a fuel injection device belonging to the field of F02M 21 / 00, which uses its own fuel to preheat the vaporization pipe and enhances the combustion effect through the nozzle, so that the liquid fuel in the vaporization pipe is vaporized and sprayed out through the nozzle and then again It is ignited by its own fuel to continuously vaporize the liquid fuel in the vaporization tube. Background technique [0002] The vaporization tube in the fuel injection device is generally spiral and hollow inside. One end of the vaporization tube has a liquid inlet and the other end has a gas outlet. Liquid fuel such as liquid alcohol flows in from the liquid inlet and is heated in the vaporization tube. Vaporization is ejected from the gas outlet. At present, the heating method of the vaporization tube is generally electric heating tube heating. During the working process of the fuel injection device, the electric heater must be additionally c...
