Abstract

The invention relates to a turbocharger, a regulation method, an engine and a vehicle. One side end surface of the supercharging housing of the turbocharger is provided with a main air intake and a secondary air intake assembly, and a plurality of secondary air intakes of the secondary air intake assembly are arranged at intervals on the main air intake On the outside, the main impeller assembly is set in the booster housing, the secondary impeller shaft of the secondary impeller assembly is movably fitted on the main impeller shaft, the secondary impeller shaft can be optionally connected coaxially with the main impeller shaft, and the intake housing Set on the end face of one side of the pressurized housing, the air intake housing is provided with a main air intake channel and multiple secondary air intake channels that can be opened, the main air intake channel communicates with the main air intake port, and multiple secondary air intake channels The secondary air intake passages are arranged around the outer side of the main air intake passage at intervals, and the secondary air intake passages and the secondary air intake ports are arranged correspondingly. 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, 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...
