とを特徴とする、エンジン冷却装置。 Cooling of the combustion chamber of the engine, which is formed by the cylinder head, the cylinder block that overlaps with the cylinder head, and the piston that slides inside the engine cylinder of the cylinder block, is separated into the cylinder head side and the cylinder block side. In order to achieve this, an upper oil circulation system that lubricates the cylinder head side and a lower oil circulation system that lubricates the cylinder block side are provided separately. The oil jacket is provided with an oil jacket for holding cooling oil, and the oil jacket is formed with a top surface inclined along the longitudinal direction of the engine in order to collect and discharge air bubbles accumulated in the oil jacket in one place. At the same time, a bubble discharge passage for discharging the bubbles guided along the inclined top surface to the oil pan connected to the lower part of the cylinder block communicates with the upper part of the oil jacket and the oil pan. An engine cooling device characterized in that the engine cooling device is interposed between the engine cooling device and the engine cooling device.
