A sensor probe having a first sensing element and a second sensing element. The first sensing element generates current changes in response to changes in a relative amount of a target element present in reference air versus a first exhaust gas chamber of the sensor probe. A second sensing element generates current changes in response to changes in a relative amount of the target element present in the first exhaust gas chamber and either a second exhaust gas chamber of the sensor probe or reference air.

Multi-element sensors

A valve assembly for an exhaust gas recirculation system of an engine. The valve assembly includes a three-way flow path housing defining an inlet, a first outlet, and a second outlet. A valve actuator is spaced apart from the three-way flow path housing and connected to the three-way flow path housing by a linkage. Actuation of the linkage by the valve actuator simultaneously opens the first outlet and closes the second outlet, and simultaneously closes the first outlet and opens the second outlet.

Exhaust gas distribution valve

An EGR device includes a housing having an outer pipe and an inner pipe. The inner pipe is accommodated in the outer pipe to define an annular passage externally with the outer pipe. The inner pipe defines an inner passage internally. The inner pipe has pipe through holes. A rotary valve is accommodated in the inner pipe. The rotary valve has valve through holes. The rotary valve is rotatable to communicate the annular passage with the inner passage through the valve through holes and the pipe through holes. The rotary valve is rotatable to block the inner passage from the annular passage.

EGR device having rotary valve

An EGR device includes a housing and a valve. The housing has an outer pipe and an inner structure. The inner structure is located inside the outer pipe to define an annular passage externally with the outer pipe. The inner structure defines an inner passage internally. The inner structure has apertures. The valve is in a tubular shape and is located inside the inner structure. The valve is slidable in an axial direction to communicate the annular passage with the inner passage through the apertures and to block the inner passage from the annular passage.

EGR device having slidable valve

A method and system for increasing regenerative energy available during deceleration by reducing engine pumping losses. The method includes a controller that reduces fuel delivery to the engine and closes an engine throttle during deceleration. The controller identifies the maximum kinetic energy available during deceleration and opens an exhaust gas recirculation (EGR) valve and engine throttle as necessary to reduce a vacuum in an engine intake manifold, thus minimizing engine pumping losses and increasing regenerative energy available during deceleration while ensuring that a catalyst temperature is above a catalyst temperature threshold.
