Abstract
An internal combustion engine includes a cylinder block with cooling fins cast integral therewith, and a cylinder head bolted on top of the cylinder block, first coolant passages being provided in the area of at least one cylinder contained in the cylinder block, which passages are connected to second coolant passages located in the cylinder head. Cooling efficiency is increased by providing heat exchange passages in an outer region of the cooling fins, which together with the first coolant passages and the second coolant passages, form a closed loop system within the engine.
