Abstract:
A head-side jacket through which coolant flows is formed in a cylinder head. A main circulation path and a sub circulation path through which coolant fed from a coolant pump respectively circulates are formed. The head-side jacket is separated into an exhaust-port side jacket formed around an exhaust port, and a combustion-chamber-side jacket closer to a combustion chamber than the exhaust-port-side jacket. A heat exchanger is not formed in the main circulation path including the combustion-chamber-side jacket, but is formed in the sub circulation path excluding the combustion-chamber-side jacket and including the exhaust-port-side jacket.

Claim (Index 1):
A cooling device for an engine including an engine body having a cylinder block and a cylinder head for defining a combustion chamber, and an exhaust port formed in the cylinder head, and a heat exchanger disposed outside the engine body, the cooling device comprising:\n a coolant pump for feeding coolant into the engine body; a head-side jacket formed in the cylinder head, and through which coolant flows; and a circulation path through which coolant discharged from the coolant pump and returning to the coolant pump flows, wherein the head-side jacket includes an exhaust-port-side jacket formed around the exhaust port in the cylinder head, and a combustion-chamber-side jacket formed at a position closer to the combustion chamber than the exhaust-port-side jacket, the circulation path includes a main circulation path through which coolant passing through the combustion-chamber-side jacket circulates, and a sub circulation path through which coolant passing through the exhaust-port-side jacket circulates, and the heat exchanger is disposed at a downstream position of the sub circulation path with respect to the coolant pump, and at an upstream position of the sub circulation path with respect to the exhaust-port-side jacket.
