    Abstract: An internal combustion engine includes a cooling system having a coolant delivery matrix, such as for providing a two phase (vapour) cooling system for the engine. The coolant delivery matrix is configured for location in a cylinder block of an engine housing of the internal combustion engine. The coolant delivery matrix includes a manifold and a plurality of pipes extending from the manifold. The coolant delivery matrix is further configured to locate around at least one cylinder in the cylinder block, and each of the plurality of pipes has at least one aperture being directed to spray liquid coolant at a wall of the at least one cylinder.

    Abstract: The present invention relates to a universal powertrain for controlling an effort request and/or a flow request to a powertrain based on a demanded effort or demanded flow for the powertrain. The universal controller includes a configurable powertrain model and a configurable optimiser module. The universal controller is configurable to control a class of generic powertrains comprising J generic power sources, K generic power sinks, and L generic couplings. The universal controller is arranged to receive an input file of a plurality of input parameters to configure the universal controller to control a specific powertrain having a powertrain architecture with N power sources, M power sinks, and X couplings, the configurable powertrain model comprising: (a) a generic powertrain component library configured to provide a model of each of the N power sources, M power sinks and X couplings of the specific powertrain, and (b) a connection parameter module configured to define a model architecture of the N power source models, M power sink models and X coupling models which is representative of the powertrain architecture based on flow weight parameters and effort weight parameters of the input file, the configurable optimiser module comprising: a generic performance objective function library comprising a plurality of configurable performance objective functions from which a cost function is configurable based on input parameters of the input file, wherein the configurable optimiser module is configurable to calculate at least one of an optimised effort request or an optimised flow request for each of the N power sources of the specific powertrain based on: the cost function, the powertrain model of the specific powertrain, the demanded effort request of demanded flow request.

    Abstract: An engine assembly comprises an exhaust gas recirculation circuit, an aftertreatment apparatus and a controller. The controller is configured to determine a desired proportion of exhaust gas to be directed to the exhaust gas recirculation circuit. The controller is further configured to determine, based on the proportion of exhaust gas to be directed to the exhaust gas recirculation circuit, a baseline value for an extent to which to open the exhaust gas recirculation valve for a clean aftertreatment apparatus. The controller is further configured to determine a compensation function based on an inferred aftertreatment flow restriction value. The controller is further configured to control the extent to which the exhaust gas recirculation valve is open based on the baseline value modified by the compensation function in order to maintain the desired proportion of exhaust gas to be directed to the exhaust gas recirculation circuit.

    Abstract: A method of priority management of an electric work vehicle while the electric work vehicle is connected to a charging module. A duration of immobilization, a target temperature, a target state of charge, a minimum rise duration and a minimum charge duration are used to determine a charging start time and a heat exchange start time based on a time priority decision. The time priority decision is made such that the actual temperature of the first fluid is between the threshold temperature and the target temperature at the anticipated fluid usage time; an actual state of charge is between the threshold state of charge and the target state of charge at the anticipated start time; and an actual charge speed is below a threshold charge speed.

    Abstract: A hybrid power unit of a work machine includes an engine and an energy storage device. The engine includes a crankshaft for driving a load and the crankshaft is attached to an energy storage device via a clutch. The energy storage device can be charged by the engine to store energy, that may be used to provide, when required, a boost to engine performance. The clutch may engage/disengage the energy storage device from the engine and/or control a clutch pressure. The clutch protects the crankshaft from shock loading and can slip to prevent over-torqueing of the crankshaft.

    Abstract: Ducting is described. The ducting is for use with: a high pressure turbocharger (HPT) having a HPT exhaust gas outlet, and a low pressure turbocharger (LPT) having an LPT exhaust gas inlet. The ducting comprises first and second ducts (LPT). The first duct has a first duct inlet that is connectable to the HPT exhaust gas outlet and a first duct outlet that is connectable to the LPT exhaust gas inlet. The second duct has a second duct inlet for wastegate gases from a wastegate of the and a second duct outlet located within the first duct. The second duct comprises an elongate second duct portion which is a length of the second duct located within the first duct. The second duct portion comprises the second duct outlet and is arranged such that the second duct outlet is pointed towards the first duct outlet.
