an oil return converter

Abstract

The invention discloses a return oil converter applied to a motor vehicle using a diesel engine. The return oil converter structurally comprises an installation base, an oil control pipe, a floating device and an oil drainage pipe. The installation base is fixed to the motor vehicle and arranged on the oil drainage pipe. Ports of the installation base are connected with an oil return port, an oil inlet and an oil tank of the engine correspondingly. Return oil with heat in the engine is directly returned to the oil inlet of the engine through the return oil converter, fuel oil with the sufficient heat is provided for the engine and is directly combusted by the engine, and therefore the defects that when an existing diesel vehicle using low-grade fuel oil travels at the low temperature, the viscosity and density of diesel oil are increased, flowability is poor, an engine is unsmooth in oil supply and large in abrasion, the vehicle is likely to fire off, and fuel economy is poor are overcome. The return oil converter is simple in structure, high in practicability and capable of being cooperated with an electric heater for use. By means of research for many years of the inventor, the diesel vehicle in which low-grade fuel oil is added can normally travel even at -25 DEG C.

Description

technical field [0001] The invention relates to an engine oil and gas device, in particular to an oil return converter. Background technique [0002] At present, diesel engines are widely used in trucks, buses, buses, agricultural machinery, construction machinery, ships, electric power and other fields. In actual use, low-grade diesel is cheaper and more fuel-efficient than high-grade diesel. According to the fuel consumption per 100 kilometers of large trucks, the fuel consumption of No. 0 diesel is 30 liters per 100 kilometers, and the fuel consumption of No. The price difference with -10 diesel is about 0.5 yuan. Low-grade diesel has good economy, but low-grade diesel has a high cold filter point. When a diesel vehicle runs with low-grade fuel at low temperature, the viscosity and density of diesel will increase, and the surface tension will increase, making the fluidity of diesel worse. , and diesel oil will precipitate crystals at low temperatures, and the crystals w...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an oil return converter, the purpose of which is to solve the problems that the density of diesel oil increases and the viscosity is high when diesel vehicles are running on low-temperature low-grade oil, and diesel vehicles are prone to engine wear and flameout. ; and for the disadvantages of complex structure, cumbersome installation and high cost of water circulation heating devices in the current market; there are also disadvantages such as the temperature of the electric heating system can not meet the combustion demand after the temperature of the electric heating system is reduced to -15°C; , the problem of not being able to directly pass the return oil to the engine due to gas accumulation
