A flow management device comprises an outer chamber with an inlet arranged to receive a flow in a first flow direction and an outlet arranged to provide the flow in a second flow direction different from the first direction, and a duct arranged within the chamber, the duct having a first end configured to receive the flow from the inlet and a second end configured to release the flow towards the outlet, wherein a cross-sectional area of the duct increases towards each of the first and second ends of the duct.

Flow management device

Methods and systems are provided for an EGR valve diagnostic. In one example, a method may include actuating an EGR valve between first and second positions. The method may further includes determining one or more characteristics of the EGR valve during the diagnostic to determine if an EGR valve cleaning is desired.

Methods and systems for EGR valve diagnostics

A method of cleaning an EGR valve operatively connected to an exhaust flow from an engine includes determining when cleaning is required, and when cleaning is required, operating the engine in a high temperature mode in which the temperature of exhaust gas exiting the engine is increased while producing a flow of exhaust gas having a low unburnt hydrocarbon content. The method further includes opening the EGR valve to allow hot exhaust gas to flow therethrough so as to remove combustion by-products that are fouling the EGR valve. Furthermore, the method includes producing an estimate of accumulated combustion by-product fouling of the EGR valve. The estimate is then used to determine whether and when to clean the EGR valve.

Method of cleaning an exhaust gas recirculation valve

An engine is provided herein. The engine includes a crankshaft, an engine casing, an oil pump, and an accessory drive, the oil pump having an input member which is driven from the crankshaft at a location on the opposite side of the accessory drive to the engine casing.
