Abstract

The invention relates to a turbocharger. The turbocharger comprises a supercharging shell and an air inlet shell. A main air inlet and a secondary air inlet assembly are arranged on the end face of one side of the supercharging shell. The secondary air inlet assembly comprises a plurality of annular secondary air inlets, wherein the secondary air inlets of the secondary air inlet assembly are formed in the outer side of the main air inlet at intervals. 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 inletchannel and a plurality of secondary air inlet channels. The main air inlet channel communicates with the main air inlet, 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, and a one-way valve is correspondingly arranged in each secondary air inlet channel. The turbocharger can balance the power performance on a low-speed working condition and on a high-speed working condition, so that the economic performance and the emission performance of an 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. 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 innovative Directly determine the power, econom...
