Abstract

The invention provides an oil supply system and control method of a turbocharger, and a car, and relates to the technical field of cars. The problem that the working state of turbochargers is poor due to the fact that the lubricating and cooling effects of bearing systems of the turbochargers are poor is solved. The oil supply system of the turbocharger comprises an oil accumulator which communicates with an oil supply system of an engine through an oil inlet pipe, and a middle shell which communicates with the oil accumulator through a first conveying pipe and a second conveying pipe, wherein a first control valve is arranged on the first conveying pipe, and a second control valve is arranged on the second conveying pipe. According to the oil supply system of the turbocharger, the supply pressure and supply amount of lubricating oil entering a bearing system of the turbocharger can be reasonably adjusted according to the actual working conditions of the engine and the turbocharger, so that the lubricating and cooling effects of the bearing system are effectively improved, and the turbocharger reaches the good working state. The oil supply system of the turbocharger is mainly applied to cars.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an oil supply system of a turbocharger, a control method and an automobile. Background technique [0002] A turbocharger is a device that can improve the power and fuel economy of the engine and reduce its exhaust emissions without changing the volume and weight of the engine. Wherein, the turbocharger is mainly composed of a compressor housing, an intermediate housing, a turbine housing, and a compressor impeller located inside the compressor housing, a turbine located inside the turbine housing, and a turbine located inside the intermediate housing. The bearing system used to connect the compressor wheel and turbine constitutes. When the turbocharger is working, the turbine can rotate under the impetus of the engine exhaust gas, and drive the coaxially connected compressor impeller to rotate, so that fresh air can pass through the high-speed rotating compressor impeller an...
