Abstract: A valve assembly comprises: a valve housing comprising an interior cavity having upstream side and a downstream side; and a valve member movable within the valve housing between a closed position in which flow between the upstream side and the downstream side is prevented or substantially prevented and one or more open positions in which flow between the upstream side and the downstream side is enabled. The valve assembly further comprises: a sensor mounting flange on an exterior surface of the valve housing; a first bore in the valve housing linking the upstream side of the valve housing and the sensor mounting flange; and a second bore in the valve housing linking the downstream side of the valve housing and the sensor mounting flange; such that a sensor configured to measure a differential between the upstream side and the downstream side is mountable directly on the valve assembly.

Abstract: An aftertreatment assembly for an internal combustion engine is disclosed. The assembly includes an aftertreatment component with an inlet, and a pipe connection fluidly connected to the inlet. The pipe connection includes an adjustable spherical pipe joint that joins two angularly offset pipe sections, and a slip pipe joint that joins two axially aligned pipe sections and that can adjust a combined length of the two axially aligned pipe sections. The assembly allows for compensating the positional and orientational displacements between an exhaust outlet and the inlet of the aftertreatment assembly.

Abstract: A turbocharger housing for an engine includes a specifically designed mounting interface provided at a turbine outlet of a turbine housing. In particular, the mounting interface includes a mounting flange that is inclined with respect to a plane that is orthogonal to the longitudinal direction of the turbocharger. In particular, in case of an arrangement where the turbocharger is arranged such that the shaft of the same extends substantially horizontally, the mounting flange of the turbine outlet is rotated by a predetermined angle of, for example, 20 degrees about the vertical axis,

Abstract: An exhaust mixer provided may be used for mixing an additive, such as urea, in exhaust fluid flow. The exhaust mixer may be useful in reducing or preventing build-up of solid additive deposits by increasing efficiency of mixing of the additive. The exhaust mixer may be located at least partially within a mixing conduit and includes plurality of elongate mixing blades held in spaced configuration by a support. Each mixing blade may have a longitudinal axis extending along a longitudinal axis of the mixing conduit, wherein an injector module may be located upstream of the inlet of the mixing conduit.

Abstract: An exhaust fluid treatment apparatus used to treat exhaust fluid emitted by a combustion engine includes a check of its functionality. A method of monitoring operation of an exhaust fluid treatment apparatus includes comparing a calculated temperature difference with an expected temperature difference associated with combustion of fuel. If the calculated temperature difference is within an acceptable margin of the expected temperature difference, further fuel injection may be permitted. If the calculated temperature difference is outside the acceptable margin of the expected temperature difference, a temperature of the exhaust gas upstream of the exhaust fluid treatment apparatus may be increased.

Abstract: In an engine unit including a combustion unit and an exhaust fluid recirculation apparatus where unburnt fuel is provided to an exhaust flow treatment apparatus for combustion, it may be desirable to prevent unburnt fuel from entering the exhaust fluid recirculation apparatus. A method of controlling operation of an engine unit includes confirming that a valve of the exhaust flow recirculation apparatus is closed, and overriding a control signal for controlling the valve in order to ensure that the valve remains closed before injecting fuel upstream of the valve for combustion in the exhaust fluid treatment apparatus.

Abstract: The present disclosure is directed towards a method of controlling an engine system comprising an exhaust aftertreatment module and a controller. The exhaust aftertreatment module is for receiving exhaust gas from an internal combustion engine and comprises a reductant injector selectively operable to inject a reductant fluid from an injector outlet. The controller is configured to control injection of reductant fluid in one of a plurality of different regimes. A first regime comprises injecting reductant fluid in accordance with a first set of injection parameters for reacting with, and substantially reducing, one or more components of the exhaust gas in the exhaust aftertreatment module. A second regime comprises injecting reductant fluid in accordance with a second set of injection parameters for expelling solid reductant deposits formed over the injector outlet. The method comprises determining which of the plurality of regimes to implement. The first regime is implemented when the exhaust gas temperature is above a threshold temperature and the second regime is implemented when the exhaust gas temperature is below the threshold temperature.
