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

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.
