Abstract: An internal combustion engine has an oil cooler arranged in a water tank of a cylinder crankcase, with cooling water from a cooling water circuit flowing through the water tank. To improve the cold start properties of an internal combustion engine, without increasing the installation space, while also permitting subsequent retrofitting, an electric heating element is arranged in the water tank.

Abstract: In an accessory unit drive arrangement of an internal combustion engine the accessory unit is mounted on the engine such that its drive shaft is arranged in axial alignment with an engine-operated shaft. The drive shaft is coupled to the engine-operated shaft by a coupling structure which includes a pin which projects axially eccentrically from the end face of the engine-operated shaft and engages a carrier mounted on the drive shaft of the accessory unit. The engine-operated shaft is supported by a friction bearing and a lubricant collecting space is in communication with the friction bearing so as to collect lubricant leaking from the bearing for the lubrication of the coupling structure.
