Abstract

A liquid cooled internal combustion engine having a bypass line with a controllable shut off element so that coolant can bypass the cylinder head in certain engine operating conditions. The bypass line branches off from the coolant circuit upstream of the cylinder head and returns to the coolant circuit downstream of the cylinder head.
