Abstract
A cooling structure of an internal combustion engine includes a cylinder block, an inner-block coolant passage, a cylinder head, and an inner-head coolant passage. In the cylinder block, cylinders are provided in a row in a cylinder row direction. The inner-head coolant passage is provided in the cylinder head and includes a main coolant passage, an upper exhaust side coolant passage, and a lower exhaust side coolant passage. The main coolant passage is provided above combustion chambers and extends in the cylinder row direction so that a coolant flows into the main coolant passage from the inner-block coolant passage at a first end side of the cylinder head in the cylinder row direction and so that the coolant flows out from the main coolant passage at a second end side of the cylinder head opposite to the first end side in the cylinder row direction.
