Description
Technical Field
The utility model relates to the technical field of internal combustion engines, in particular to a heating type heavy oil and alcohol-based fuel gas auxiliary injection metering valve.
Background
The existing valve for the heavy oil and alcohol-based fuel ignition type internal combustion engine mainly comprises the step of tearing fuel by a Laval effect in a mode of air-clamping injection to atomize the fuel. However, the heavy oil has high viscosity and the energy required for igniting the alcohol-based fuel is high, so that the requirement on the atomization effect of the fuel of the internal combustion engine is extremely high, the improvement on the atomization effect of the fuel is an essential subject for the current research of the internal combustion engine of the heavy oil and the alcohol-based fuel, and however, under the condition that the mechanical structures of the metering valves are similar, how to change the enthalpy and the entropy of the fuel is the current difficulty. The enthalpy and entropy of the fuel can be changed by changing the temperature and the pressure, but the track pressure on the internal combustion engine is generally within a certain interval range, and the atomization effect is not ideal by simply increasing the pressure of the fuel. Therefore, the internal combustion engine mainly comprising heavy oil and alcohol-based fuel is started under the low-temperature condition, the combustion effect is poor, and carbon deposition is serious due to poor atomization effect; secondly, in cold start at low temperature, the cold start time is long and even can not be started because the energy required for ignition of the alcohol-based fuel is too high, and the exhaust emission exceeds the standard because of incomplete combustion of the fuel.
Disclosure of Invention
The utility model aims to provide a heating type heavy oil and alcohol-based fuel gas auxiliary injection metering valve, which utilizes a heating device to heat heavy oil or alcohol-based fuel to be injected and atomized, so that enthalpy and entropy of the heavy oil or alcohol-based fuel are increased, and a better atomization injection effect of the fuel is achieved, so that the fuel is easier to burn, and the conditions that the alcohol-based fuel of an engine is difficult to ignite at normal temperature and cold start and the heavy oil fuel is difficult to cold start are improved.

The heating device is arranged in the inner cavity of the hollow valve rod of the gas-assisted injection metering valve. The hollow valve rod is used as a necessary passage of fuel, is closer to the jet orifice, and can achieve the effects of maximum heating, enthalpy increase and entropy increase with the lowest consumption of heating power.
The heating device is a heating rod, the head end of the heating rod is fixed on a fixing seat, and the fixing seat is arranged at the inlet of the flow passage of the gas-assisted injection metering valve. The heating rod is fixed through the fixing seat, the heating rod is positioned at the center of the cross section of the flow channel, fuel flows through the periphery of the heating rod, and the fuel is heated uniformly, so that the fluidity of the fuel is facilitated.
The heating device is electrically connected with the power controller, and the power controller is arranged outside the gas-assisted injection metering valve. The power controller can automatically control the heating power of the heating device so as to achieve the constant temperature of the fuel and finally achieve the stability of the atomization degree of the fuel.
The outer wall of the fixing seat is provided with a temperature sensor, and the temperature sensor is electrically connected with the power controller. The temperature sensor feeds back the fuel temperature to the power controller, and the power controller adjusts the power in real time so as to achieve the effect of constant heating temperature.
