Abstract: PROBLEM TO BE SOLVED: To provide a cooling device capable of efficiently collecting air in a cooling circuit to an air bleeding part in air bleeding of the cooling circuit. SOLUTION: In this cooling device, a mode is changed over between a normal mode driving an electric pump 3 as normal and an air bleeding mode driving the electric motor for air bleeding. The electric motor 3 is driven and controlled to provide change of delivery quantity of the electric pump 3 in a change pattern to make air accumulated at each section of the cooling circuit in the air bleeding mode. When the delivery quantity of the electric pump 3 is reduced according to the change pattern through the control, air accumulated at a section where air easily flows in the cooling circuit 2 is made flow toward a reservoir tank 9. When the delivery quantity of the electric pump 3 is increased according to the change pattern, air accumulated at the section where air easily flows in the cooling circuit 2 is effectively made flow toward the reservoir tank 9 and is collected in the tank 9.

Abstract: PROBLEM TO BE SOLVED: To determine whether a valve and a thermostat provided in an exhaust port function normally or not. SOLUTION: An ECU executes a program comprising the following steps. During warming-up of an engine (YES in S104), if an absolute value of deviation of water temperature TR detected by a water-temperature sensor from an estimated water-temperature TE is greater than a specified deviation T(0) (YES in S106), then in the step (S108) the state of the valve placed so as to change the gas-flow distribution in an exhaust port is brought in a closed state during the warming-up. If the valve is in open state (YES in S108), the valve is determined to be abnormal in the step (S110). If the valve is in a closed state (NO in S108), the valve is determined to function normally in the step (S112), and the thermostat is determined to function improperly in the step (S114).

Abstract: PROBLEM TO BE SOLVED: To suppress occurrence of unevenness in warming-up property among a plurality of suction ports due to worsening of warming-up property of suction ports close to a flow-in passage and a flow-out passage in cylinders closest to the passages and suppress reduction of improvement effect of emission and fuel economy.
SOLUTION: In the cylinder closest to the flow-out passage 8, a flow-out position of cooling water to a water jacket 5 in a supply passage 15 is eccentric by predetermined amount a1 onto a suction port 22b side remote from the flow-out passage 8. For this reason, cooling water entering the water jacket 5 fom the supply passage 15 remains easily around the suction port 22a close to the flow-out passage 8 in No.1 cylinder. In No.7 cylinder closest to the flow-in passage 7, the flow-out position is eccentric by predetermined amount a7 onto a suction port 22a side remote from the flow-in passage 7. For this reason, cooling water entering the water jacket 5 from the supply passage 15 remains easily around the suction port 22b close to the flow-in passage 7 in No.7 cylinder.
