Abstract
An internal combustion engine including a block, a head coupled to the block to at least partially define a cylinder therebetween, and a compressor assembly having an inlet and an outlet in fluid communication with the cylinder. Where the compressor is operable in a first mode, in which a first portion of the gasses exiting the outlet are directed to the cylinder and a second portion of the gasses exiting the outlet is recirculated back to the inlet.
Claims10
An intake system for use with an internal combustion engine having at least one cylinder, the intake system comprising:
- a compressor assembly having a compressor housing and a compressor wheel movable with respect to the compressor housing, wherein the compressor housing includes a compressor inlet and a compressor outlet, and wherein the compressor assembly is operable in an activated configuration in which the compressor wheel is driven relative to the compressor housing, and a deactivated configuration in which the compressor wheel is not driven relative to the compressor housing;
- a passageway having a first end open to and in fluid communication with the inlet of the compressor assembly and a second end open to and in fluid communication with the outlet of the compressor assembly;
- a valve at least partially positioned within the passageway and adjustable between an open configuration, in which the first end is in fluid communication with the second end via the passageway, and a closed configuration, in which the first end is not in fluid communication with the second end via the passageway;
- and
- a controller in operable communication with the compressor assembly and the valve, wherein the controller is operable in:
- a first mode in which the compressor assembly is in the activated configuration and the valve is in the open configuration,
- a second mode in which the compressor assembly is in the activated configuration and the valve is in the closed configuration, and
- a third mode in which the compressor assembly is in the deactivated configuration and the valve is in the open configuration.
