Abstract

A liquid-cooled internal combustion engine has cylinder banks that tilt toward one another, to for a V engine. A coolant, which is fed to the exhaust gas-sided cooling jackets in the cylinder banks, is fed over cylinder heads with cross flow to cooling jackets. The coolant drains over break-throughs in the cylinder bank boundaries into an outflow line in the V-space. The outflow line and the inflow line are connected to a coolant pump. The coolant is fed from the inflow line over distribution channels at a housing end to the exhaust gas-sided cooling jackets.
