Abstract

The invention relates to a control method of a turbocharger. The control method can selectively control the opening quantity and opening angle of the secondary air intake passage, and control the main impeller assembly and the secondary impeller assembly according to the demand of the supercharging pressure. The rotation level is different to meet different intake air volume requirements, so as to take into account the power performance under low-speed working conditions and high-speed working conditions, and avoid affecting the economic 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 control method of 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 determi...
