Problems solved by technology

[0004] Gasoline (or diesel) is not only a fuel, but also a solvent. When gasoline (or diesel) is extracted from petroleum, a certain amount of colloidal substances are dissolved in the petroleum. The viscosity of the colloidal substances makes gasoline or diesel The fluidity of diesel oil is poor at low temperature, and the atomization effect is not good when it is sprayed from the fuel injector of the engine.

Abstract

The invention discloses a device for preheating fuel oil by circulating and absorbing waste heat of an engine. The heat exchanger is provided with an inner pipe, and the two ends of the inner pipe respectively constitute a circulating water inlet and a circulating water outlet. The common inlet and outlet of the pipe constitute the fuel inlet and the fuel outlet respectively. The fuel inlet and the fuel outlet are respectively arranged at both ends of the inner pipe. The fuel outlet and the circulating water outlet are located on the same side. The circulating water inlet of the heat exchanger and the circulation of the engine cooling system The hot water outlet is connected, the circulating water outlet of the heat exchanger is connected to the circulating water cooling water inlet of the engine cooling system, the fuel oil outlet of the heat exchanger is connected to the fuel oil and gas inlet of the oil-gas separator through a pipeline, and the gas outlet of the oil-gas separator is connected to the suction of the engine The gas inlet and the fuel liquid outlet of the oil-air separator are connected to the fuel injector of the engine. Increase the fuel utilization rate of the engine, save oil, save 5% to 20%, recycle the waste heat generated by the engine, and save energy.

Description

technical field [0001] The invention relates to the technical field of fuel oil preheating of engines, in particular to a device for circulatingly absorbing waste heat of an engine to preheat fuel oil, which is suitable for fuel oil preheating of gasoline and diesel engines. Background technique [0002] The thick black smoke emitted from the back of the street bus and the pungent gasoline smell produced by the car pollute the environment and waste resources. Part of the exhaust gas of the car is gasoline or diesel oil that has not had time to burn, and the other part is incompletely burned fuel oil and other exhaust gases . Therefore, the combustion method of the current engine needs to be improved. [0003] After 1 mass of gasoline (or diesel) is burned, there are about 30% effective work, 10% to overcome mechanical friction, 20% heat loss (discharged through the cooling exhaust pipe of the water tank), and 20% to be directly discharged without burning to produce gasoline...
