Abstract:
A turbocharged internal combustion engine assembly with exhaust gas recirculation comprisingan internal combustion engine having an air intake and an exhaust gas outlet; an exhaust gas turbine having a turbine inlet and a turbine outlet; an air compressor driven by said exhaust gas turbine; an air intake line extending from said compressor to said engine intake; an exhaust line extending from said exhaust gas outlet to said turbine inlet; an exhaust gas recirculation line extending from a first point on said exhaust line downstream of said engine to a second point on said air intake line upstream of said engine; a combustion bypass line extending directly from a third point on said air intake line upstream of said exhaust gas recirculation line to a fourth point on said exhaust line downstream of said exhaust gas recirculation line; and a pressure adjusting feature disposed along at least one of said air intake line and said exhaust gas line to maintain the pressure at said fourth point below the pressure at said third point and above the pressure at said second point.
