Abstract: Side surfaces of an end cam cap and a pair of side surfaces of a recess for cam cap form two cross-sectional area gradually changing gaps therebetween. A gasket is filled between an inner surface of the recess for cam cap and an outer surface of the end cam cap. The inner surface includes the side surfaces of the recess for cam cap and the outer surface includes the side surfaces of the end cam cap.

Abstract: A cooling device for an internal combustion engine includes a HT cooling system, a LT cooling system, and an electronic control unit. The electronic control unit is configured to, if a HT temperature has reached a HT determination value, control an operation state of the HT cooling system to start cooling for maintaining the HT temperature at a HT target temperature. The electronic control unit is configured to, if a LT temperature being a temperature of a LT cooling medium has reached a LT determination value, start a LT cooling control for maintaining the LT temperature at a LT target temperature under a specific condition where an early warm-up of the internal combustion engine is not required. The electronic control unit is configured to start the LT cooling control if the HT temperature has reached the HT determination value under a condition where the early warm-up is required.

Abstract: A cooling water channel core that is used for casting of the cylinder head includes a core body for obtaining a channel that passes through the periphery of a plurality of intake valve insertion holes, and a core print that is integrally formed with the core body at a location that is between an adjacent two combustion chambers of the core body and that comes in contact with an outer casting mold in a casting mold manufacturing step. When the cooling water channel core is arranged inside the outer casting mold and casting is performed, a cylinder head is manufactured that has an opening portion that opens in an outer face from the cooling water channel. The opening portion is sealed by a sealing plug after being utilized for sand extraction and inspection.

Abstract: A cylinder block including two different systems of cooling water channels. The cooling water at a relatively low temperature is made to flow through a first cooling water channel, while the cooling water at a relatively high temperature is made to flow through a second cooling water channel. The first cooling water channel includes an exhaust-side water jacket that is located on an exhaust side with respect to a plurality of cylinders juxtaposed in a longitudinal direction of the cylinder block and is provided in the longitudinal direction along the plurality of cylinders. The second cooling water channel includes an intake-side water jacket that is located on an intake side with respect to the plurality of cylinders and is provided in the longitudinal direction along the plurality of cylinders.
