Abstract
A turbocharger system having a compressor wheel including blades that define an inducer and an exducer, a compressor housing configured to receive the compressor wheel, and an impeller passage within which air is to be compressed by the blades, wherein the compressor housing forms an intake port configured to provide intake air to the inducer, and a bypass port opening into the impeller passage between the inducer and exducer. The bypass port places the impeller passage in fluid communication with the atmosphere without having a fluid interaction with the intake air. A bypass-air filter is adapted to filter air passing between the bypass port and the atmosphere, and is a portion of the intake-air filter.
