Title:
COOLER OF INTERNAL-COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS60128922
Kind Code:
A
Abstract:
PURPOSE:To prevent knocking and improve both the charging efficiency and fuel consumption by cooling the cylinder-head-side blocks by circulated cooling water and cooling the cylinder-block-side part using the evaporation cooling system. CONSTITUTION:When a cylinder head 1 is cooled, the conventional cooling method is used wherein a water pump 8 is actuated so as to circulate cooling water which is cooled by a radiator 10. When a cylinder block 2 is cooled, liquid in a water jacket 12 and a longitudinal slot 14 is evaporated by heat transmitted from the wall face of a cylinder bore so as to take the heat of the cylinder block 2. Steam which is generated by the evaporation is fed via a passage 16 into a heat exchanger 18 and therein heat-exchanged with cooling water in the cooling system of the cylinder head 1 to be condensed and liquefied. The condensed liquid is then had to be flown into the water jacket 12.
