Abstract: The present invention relates to a V-engine (1) having at least one turbocharger (2) and at least two cylinders (4), which is constructed as a diesel engine and as an outboard motor for aquatic vehicles and wherein an exhaust gas system (6) leading from the minimum of two cylinders (4) to the minimum of one turbocharger (2) is arranged in the interior (8) of a V formed by the cylinders (4). A vertically arranged crankshaft (11), cylinder heads (19) which are designed to fold over, and coolant circuits supplied with sea water may also be provided in the V-engine (1).

Abstract: The present invention relates to a V-engine having a crank shaft 20, two banks of cylinders, each comprising at least one cylinder, having a cylinder head in which at least one camshaft 100,102 is provided, and two auxiliary shafts 30,32 arranged substantially laterally of the crank shaft. Moreover, a force-transmitting endless element 40 is also provided, inter alia, which connects the crankshaft 20 to the auxiliary shafts 30,32 and a water pump 60. Additional endless elements 50,52 connect the auxiliary shafts 30,32 to one of the camshafts 100,102.

Abstract: The invention relates to a pump (2) which is constructed to convey coolant in an engine and wherein a tensioning element (4) designed for tensioning a drive member of the engine is integrated. Also integrated in this pump (2) is a closed pump wheel.

Abstract: Disclosed is a valve arrangement for selectively holding engine oil from leaking into an oil tank vent line. The valve arrangement includes an oil tank and a valve. The oil tank supplies engine oil to the engine lubrication circuit of a vehicle's internal combustion engine. The oil tank includes a vent opening that vents the oil tank. The valve closes the vent opening as a function of the oil pressure in the engine lubrication circuit.

Abstract: The invention pertains to an internal combustion engine with a crankcase, a crankshaft and a camshaft for controlling at least one intake and exhaust valve, as well as an oil pump for delivering lubricating oil to the crankshaft. Downstream on the outlet side of the oil pump is an oil pressure regulating valve for limiting the oil pressure. The valve gate, which is contacted by a spring element in the closing direction, depending on the amount of oil delivered and/or the oil temperature, the valve gate frees an opening that can be connected with the inlet side of the oil pump. It is suggested that the camshaft be seated in longitudinally displaceable fashion within the crankcase and form the valve gate of the oil pressure control valve. An oil pressure-limiting valve for an internal combustion engine is thus implemented in a simple way.

Abstract: Intake manifold for an internal combustion engine with a heat exchanger fastened to the intake manifold. An internal combustion engine characterized by a heat exchanger fastened to the intake manifold.

Abstract: Turbine casing for a turbocharged internal combustion engine for marine applications with an exhaust manifold that is single-piece formed with the turbine casing, and a cooling facility surrounding both the turbine casing as well as the exhaust manifold. The cooling facility is a hollow space, formed by the double wall that can be filled with coolant, whereby the coolant preferably is ocean/lake water. A separate cooling circuit from the cooling facility of the combined turbine casing and exhaust manifold is provided for the cooling of a bearing housing, which is used to support a turbine bearing.

Abstract: An exhaust gas recirculation valve having a valve member that cooperates with a valve seat of a connection neck of an exhaust gas recirculation line. The neck protrudes into a tube of the intake system of an internal combustion engine, and the valve seat points toward the inlet side of the exhaust gas recirculation line. A valve member of the exhaust gas recirculation valve is thus acted upon by the exhaust gas pressure in the closing direction, as a supplement to a compression spring counter to an armature of an electromagnet acting in the opening direction. To compensate for the forces acting in the closing direction, the exhaust gas is carried via a conduit in the valve shaft into a control chamber, which is closed off from the pressure in the tube via a movable wall, having an effective surface area that substantially corresponds to the effective surface area of the valve member.
