An engine is arranged in such a way that while the engine is running, cooling fluid flows along a flow path that goes into a cylinder block ( 12 ) from an inlet ( 12 b) at one end side of the engine main body ( 10 ), goes around the first cylinder ( 13 ) to the fourth cylinder ( 16 ) arranged in a row to go by way of the other end side of the engine main body ( 10 ), and then goes to a cylinder head ( 11 ) through a communication channel ( 17 ) and a flow path that goes into the cylinder block ( 12 ) through the inlet ( 12 b) at the one end side of the engine main body ( 10 ) and then directly goes to the cylinder head ( 11 ) through the communication channel ( 17 ). During the preheat process, warm cooling fluid stored in a thermal storage tank ( 20 ) enters into the cylinder block ( 12 ) from an inlet ( 12 a) at the other end side of the engine main body ( 10 ), then flows in the direction from the fourth cylinder ( 16 ) toward the first cylinder ( 13 ) while diverging to both sides of the row of the cylinders, and flows into the cylinder head ( 11 ) through the communication channel ( 17 ).
