Internal combustion engine fuel heating system

Abstract

The invention provides a fuel heating device for an internal combustion engine. The fuel heating device for the internal combustion engine comprises a first temperature controlled switch, a normally open solenoid valve, a cooling liquid pipeline, a fuel heater A, a fuel coarse filter B and a fuel fine filter C. The fuel heater A, the fuel coarse filter B and the fuel fine filter C form a fuel heating device body. The first temperature controlled switch, the normally open solenoid valve and the fuel heating device body are connected to form a cooling liquid circulation loop through the cooling liquid pipeline. A cooling liquid heater, a micro circulation pump and a second temperature controlled switch are connected to the water inlet pipe end and the water outlet pipe end of the fuel heating device body in parallel after being connected in series. Both an oil return pipeline and an oil supply pipeline are arranged in a cooling liquid circulation pipeline. Fuel in a fuel tank is connected with the oil inlet end of a high pressure oil pump after passing through the fuel heater A, the fuel coarse filter B, a fuel delivery pump joint and the fuel fine filter C. The outlet end of the cooling liquid heater is communicated with a cooling liquid outlet of the internal combustion engine through the normally open solenoid valve, and the water return end of the cooling liquid circulation loop is connected with the cooling liquid water return end of the internal combustion engine. The fuel heating device for the internal combustion engine is safe in structure, reliable in performance, safe, environmentally friendly and capable of bring huge economic benefits and has high readiness value.

Description

technical field [0001] The invention relates to a heating device, in particular to a fuel heating system for an internal combustion engine. Background technique [0002] In order to reduce the fuel consumption cost of the internal combustion engine, low-grade fuel is often used, which will bring huge economic benefits. Diesel. However, due to the low temperature, the fuel cannot be supplied normally, so the internal combustion engine cannot work. In order to solve the above problems, the existing technology usually adopts the method of electric heating, although this method can make the fuel supply normally, but due to the complicated temperature control, there are major safety hazards such as high fuel temperature, gas leakage in the pipeline, or fire. . Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides an internal combustion engine fuel heating system with safe structure, reliable performance, safety and environment...

Problems solved by technology

However, due to the low temperature, the fuel cannot be supplied normally, so there will be a phenomenon that the internal combustion engine cannot work

In order to solve the above problems, the existing technology usually adopts the method of electric heating. Although this method can make the fuel supply normally, but because the temperature control is relatively complicated, there are major safety hazards such as excessive fuel temperature, gas leakage in the pipeline, or fire.
