Abstract
A turbocharger for an internal combustion engine, particularly suitable for use in a work machine, is provided with a turbine having a low pressure region of minimum static pressure. A compressor has a high pressure region of maximum dynamic pressure. A conduit fluidly interconnects the high pressure region with the low pressure region. A valve is associated with the conduit for opening and closing the conduit. Compressed air or a fuel/air mixture may be bled from the compressor to the turbine over a wider arrange of operating conditions, even at low load operating conditions.
