Abstract

The invention relates to a turbocharger. The turbocharger includes a supercharging housing and an air intake housing. One end surface of the supercharging housing is provided with a main air inlet and a secondary air intake assembly. The secondary air intake assembly includes a plurality of ring-shaped secondary Secondary air inlet, multiple secondary air inlets of the secondary air intake assembly are arranged at intervals outside the main air inlet; the air intake housing is set on the end face of one side of the booster housing, There are a main air intake channel and a plurality of openable secondary air intake channels on the top, the main air intake channel communicates with the main air intake port, and a plurality of secondary air intake channels are arranged around the outer side of the main air intake channel at intervals, and the secondary air intake channels Corresponding settings of the air intake passage and the secondary air intake. The invention can take into account the power performance under the low-speed working condition and the high-speed working condition, and avoids affecting the economy and emission performance of the engine.

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...
