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 recycling absorbing waste heat of an engine for fuel preheating. A heat exchanger is provided with an inner pipe and two ends of the inner pipe form a circulating water inlet and a circulating water outlet respectively. The inner pipe is provided with shunt tubes and each shunt pipe shares the inlet and the outlet and forms a fuel oil inlet and a fuel oil outlet respectively. The fuel oil inlet and the fuel oil outlet are arranged at two ends of the inner pipe respectively and the fuel oil outlet and the circulating water outlet are located at the same side. The circulating water inlet of the heat exchanger is connected with a circulating hot water outlet of an engine cooling system and the circulating water outlet of the heat exchanger is connected with a circulating cold water inlet of the engine cooling system. The fuel oil outlet of the heat exchanger is connected with a fuel oil and gas inlet of an oil-gas separator through pipelines, wherein a gas outlet of the oil-gas separator is connected with a gas absorbing inlet of the engine and a fuel oil and liquid outlet of the oil-gas separator is connected with a fuel spray nozzle of the engine. The device for recycling absorbing waste heat of the engine for fuel preheating has he advantages that fuel utilization rate of the engine can be increased, fuel saving can reach 5% to 20%, waste heat generated by the engine can be recycled and energy can be saved.

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...
