Abstract: An exhaust gas sensor assembly for a vehicle includes a sampling tube having a proximal end connectable to a housing and a distal end configured to be suspended with a cavity of the housing. The tube defines a hollow center, an inlet, an outlet, and an exhaust gas flow path extending from the inlet, through the hollow center, and to the outlet. An exhaust gas sensor is disposed in the hollow center at the proximal end and includes a sensing element disposed in the exhaust gas flow path. a flow guide is disposed in the hollow center between the inlet and the sensing element and is configured to redirect the flow path through a passageway defined between the tube and the flow guide.

Abstract: Methods and systems are provided for a convolute-swirl integrated duct (CSID). In one example the CSID may be configured to comply with engine roll and induce swirl in an intake air flow. Engine roll is absorbed as a result of a positioning of the CSID along an intake passage upstream of a compressor inlet and pre-whirl is introduced to intake air prior to delivery of the intake air to a compressor.
