Abstract
An internal combustion engine, in particular for a vehicle, is provided. The internal combustion engine has a crankcase, a cylinder head, a coolant feed line, a cooling channel branching line, a first coolant channel which runs at least partly through the cylinder head, and a second coolant channel which runs at least partly through the crankcase. The coolant feed line is connected to the cooling channel branching line to supply coolant. The first and second coolant channels are each connected to the cooling channel branching line to be supplied with coolant from the cooling channel branching line. The cooling channel branching line is equipped with a temperature-sensitive current regulating device which is configured to variably adjust the ratio of the coolant volumetric flow rates that are from the cooling channel branching line into the first and second coolant channels over a range on the basis of the temperature.
