Abstract

The present disclosure provides a turbocharger that reduces noise generated by a wastegate. A turbocharger includes a turbocharger housing, a rotating assembly, and a wastegate. The turbocharger housing defines a wastegate opening, a resonator proximate the wastegate opening, a compressor inlet, a compressor outlet, a turbine inlet, and a turbine outlet. The rotating assembly includes a turbine and a compressor attached to each other by a shaft, where the rotating assembly is placed in the turbocharger housing. A wastegate may be movably secured to the turbocharger housing.

Description

technical field [0001] The present disclosure relates to a turbocharger system in which noise generated by a turbocharger wastegate is reduced. Background technique [0002] Engine components may incorporate a turbocharger to compress air flowing into the engine to provide a greater amount of air to each cylinder. To compress the flow of air into the engine, a turbocharger uses the exhaust flow from the engine to spin a turbine, which in turn spins an air pump (or compressor). Many turbochargers are provided with a wastegate, which acts as a valve in a turbocharged engine system to divert exhaust gases away from the turbine wheel in order to regulate turbine speed. The wastegate is usually controlled by an actuator. The wastegate is normally closed and held closed by an actuator. When the preset pressure limit is exceeded, the actuator will gradually open the wastegate to allow exhaust flow to bypass the turbine, thus regulating manifold boost pressure. Turbocharger wast...
