Abstract (en)
[origin: EP1174602A2] The invention provides less expensively a cooling structure for an internal combustion engine which, despite a simple structure, can control the flow of coolant to a cylinder and a cylinder head without allowing the coolant to stay in the cylinder, according to the temperature of the coolant, and which can expect the attainment of both the effect of suppressing a drop in temperature of residual gas and an anti-knocking effect. <??>A cooling structure for an internal combustion, comprising a first coolant circulation system and a second coolant circulation system, the first coolant circulation system having a first thermostat (5) for adjusting the amount of coolant to be circulated between a radiator (10) and the internal combustion engine, the second coolant circulation system having a second thermostat (20), the second thermostat (20) making control so that the coolant circulates in parallel to a cylinder (2) and a cylinder head (3) when the temperature of the coolant is lower than a predetermined coolant temperature, while when the coolant temperature is higher than the predetermined coolant temperature, the coolant circulates in series from the cylinder (2) to the cylinder head (3). <IMAGE>
