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.
