Abstract (en)

[origin: EP2644860A1] A cooling device 1A includes an engine 50A provided with W/Js 501, 502, and 503A, and a first control valve 31. The W/J 501 is provided at an intake side in a cylinder block 51A. The W/J 502 is provided at an exhaust side in the cylinder block 51A. The W/J 503A diverges from a given position of the W/J 501. Also, the W/J 503A is provided toward the exhaust side through the intake side of the cylinder head 52A. The first control valve 31 makes the coolant flowing state changeable between a state where the coolant is caused to flow in the W/J 501 and a state where the coolant is caused to flow in the W/Js 501 and 503A.
