Abstract: A coolant tank for a battery module is disclosed, wherein the coolant tank is configured to accommodate coolant in an inner volume delimited by a number of wall segments of the coolant tank, wherein one wall segment of the number of wall segments forms a number of recessed formations each comprising an outer surface delimiting the inner volume of the coolant tank and an inner surface delimiting a cell compartment for accommodating a battery cell. The present disclosure further relates to a battery module, a battery pack, and a vehicle.

Abstract: A method of controlling an internal combustion engine is disclosed, the internal combustion engine comprising at least two cylinders, wherein each cylinder comprises at least one fuel injector configured to inject fuel into the cylinder, wherein the method comprises controlling the fuel injection performed by the fuel injectors into the cylinders based on an estimate of a residual gas imbalance between the at least two cylinders. The present disclosure further relates to a computer program product, a control arrangement, an internal combustion engine, and a vehicle.

Abstract: Provided is an electric battery junction arrangement for connecting an electric battery arrangement to one or more electrical loads. The electric battery arrangement comprising two or more electric battery cells and a control circuit comprising: (i) a first control circuit branch connectable to a positive side of the battery arrangement and a positive side of an electrical load; (ii) a second control circuit branch connectable to a negative side of the battery arrangement and a negative side of an electrical load; (iii) at least one semiconductor apparatus provided between and configured to control electric current between the battery arrangement and the loads; and (iv) a switching apparatus comprising at least one mechanical switch arranged in an electrical circuit connection between the first and the second control circuit branch for electrically connecting and disconnecting the first and the second control circuit branch to and from each other.

Abstract: Disclosed is a four-stroke direct injection engine comprising a camshaft, and exhaust valve, and a control system. The control system is configured to change the timing of the camshaft to advance a closing of the exhaust valve, control a first fuel injection step during a compression stroke of the piston, control a second fuel injection step during a power stroke of the piston, and control a third fuel injection step, after the second fuel injection step, during the power stroke of the piston.

Abstract: A four stroke internal combustion engine is disclosed comprising at least one cylinder arrangement, an exhaust conduit, and at least one turbine. The cylinder arrangement comprises an exhaust port arrangement configured to open and close an exhaust flow area, ACYL. The cylinder arrangement has a maximum volume, VMAX. The exhaust conduit extends between the exhaust flow area, ACYL, and a turbine wheel inlet area, ATIN, of the turbine and has an exhaust conduit volume, VEXH that is ?0.5 times the maximum volume, VMAX. The exhaust port arrangement is configured to expose the exhaust flow area, ACYL, at a size of at least 0.22 times the maximum volume, VMAX, when a piston of the cylinder arrangement is at the bottom dead centre, BDC.

Abstract: A four-stroke internal combustion engine is disclosed comprising an exhaust valve control arrangement with an exhaust valve phase-shifting device configured to phase-shift control of the at least one exhaust valve to a state where the at least one exhaust valve is controlled in such a way that it is opened during the expansion stroke of the engine and closed during the exhaust stroke of the engine, in order to achieve engine-braking via compression in the cylinders during the exhaust stroke. An inlet valve control arrangement comprises an inlet valve phase-shifting device configured to regulate the amount of air pumped through the engine during the engine braking by regulating the phase-shift of the at least one inlet valve. The present disclosure also relates to a vehicle comprising an engine and method of controlling an engine, a computer program and a computer program for performing a method of controlling an engine.
