The invention relates to a turbocharger, an adjusting method, an engine and a vehicle. A main air inlet and a secondary air inlet assembly are arranged on the end face of one side of a supercharging shell of the turbocharger, a plurality of secondary air inlets of the secondary air inlet assembly are formed in the outer side of the main air inlet at intervals, a main impeller assembly is arrangedin the supercharging shell, and a secondary impeller shaft of the secondary impeller assembly is movably arranged on a primary impeller shaft in a sleeving manner. The secondary impeller shaft is selectively and coaxially connected with the primary impeller shaft, the end face of one side of the supercharging shell is sleeved with the air inlet shell, the air inlet shell is provided with a main air inlet channel and a plurality of openable secondary air inlet channels, the main air inlet channel communicates with the main air inlet, and the secondary air inlet channels are arranged on the outer side of the main air inlet channel at intervals in a surrounding manner. The secondary air inlet channels and the secondary air inlets are correspondingly arranged. According to the turbocharger, the adjusting method, the engine and the vehicle, the power performance on a low-speed working condition and the power performance on a high-speed working condition can be balanced, so that the economicperformance and the emission performance of the engine are prevented from being affected.
Description
technical field [0001] The invention belongs to the technical field of engine power, and in particular relates to a turbocharger, an adjustment method, an engine and a vehicle. Background technique [0002] With the rapid development of the automobile industry, the country and the market have increasingly strict requirements on fuel consumption and exhaust emissions. Since the exhaust gas turbocharger can increase the intake pressure of the engine, improve the air-fuel ratio, and make the engine burn more completely, it can improve fuel consumption while saving fuel. Engine power, reduce exhaust emissions, achieve the purpose of energy saving and emission reduction, so it is more and more widely used. [0003] In the prior art, since there is no mechanical power transmission between the turbocharger and the gasoline engine, but they are connected together in an aerodynamic way, the turbocharger is the key mechanism of the turbocharged engine, and its design is rational and i...
