Abstract:
A cooling apparatus for an entire liquid-cooled internal combustion engine using a coolant, comprising:a radiator for cooling the coolant circulating between the entire liquid-cooled internal combustion engine and said radiator; anda pump driven independently from the entire liquid-cooled internal combustion engine for circulating the coolant between the entire liquid-cooled internal combustion engine and said radiator;control means for controlling a discharge flow amount of said pump, whereinsaid control means calculates a target discharge flow amount of said pump for maintaining a predetermined temperature difference between a coolant temperature at a coolant outlet of the entire liquid-cooled internal combustion engine and a coolant temperature at a coolant inlet of the entire liquid-cooled internal combustion engine, andsaid control means controls the discharge flow amount of said pump to be the target discharge flow amount.
