<P>PROBLEM TO BE SOLVED: To provide a cooling controller for an engine capable of accelerating warming-up while preventing generation of a piston slap. <P>SOLUTION: The cooling controller includes a head-side inlet 21, a block-side inlet 22, a head-side outlet 23, a block-side outlet 24, a first control valve 11 capable of controlling inflow of a coolant to the head-side inlet 21, a second control valve 12 capable of controlling inflow of the coolant to the block-side inlet 22, a third control valve 13 capable of controlling outflow of the coolant from the head-side outlet 23, a fourth control valve 14 capable of controlling outflow of the coolant from the block-side outlet 24, and a passage section 25 for forming circulating channels P1, P2, P3. The coolant is circulated to the third circulating channel P3 by opening the fourth control valve 14 while the control valves 12, 13 are closed in warming-up of the engine. <P>COPYRIGHT: (C)2013,JPO&INPIT |
