摘要： An engine device 1 includes: a cylinder head 2 provided with a plurality of air-intake passages 36 for taking fresh air into a plurality of air-intake ports and a plurality of exhaust gas passages 37 for emitting exhaust gas from a plurality of exhaust gas ports. An air-intake manifold 3 which aggregates the air-intake passages 36 is formed integrally with one of left and right side portions of the cylinder head 2. An EGR cooler 27 is coupled to a front surface of the cylinder head 2; and EGR gas passages 31, 32 and cooling water passages 37, 38 communicating with the EGR cooler 27 are provided in a coupling portion of the cylinder head 2 with the EGR cooler 27.

摘要： An internal combustion engine (10) having an engine block (12) and one or more cylinder heads (32). The engine block houses a plurality of cylinder liners (14) and includes a cylinder liner coolant jacket (64) below an upper planar surface (30) of the engine block and in fluid communication with the plurality of cylinder liners. The one or more cylinder heads are attached to the upper planar surface of the engine block and each of the one or more cylinder heads including one or more cylinder head coolant jackets (60, 62) and one or more downward coolant passages (66) extending from the one or more cylinder head coolant jackets to the cylinder liner coolant jacket for delivering coolant from the one or more cylinder head coolant jackets to the cylinder liner coolant jacket.

摘要： A water jacket for a cylinder head includes: an upper body disposed at an upper part of the cylinder head inside the cylinder head and through which a coolant flows; a lower body disposed under the upper body inside the cylinder head and through which the coolant flows; and a connector disposed corresponding to a position of an exhaust valve between the upper body and the lower body and integrally connected to the upper body and the lower body. Tt least one penetration hole is formed in the connector along a length direction.

摘要： A cooling structure for an internal combustion engine is such that a bottom surface (51) of a cylinder head (5) is recessed so as to form recessed coolant passage (55B) that communicates with an intake-side water jacket part (22a) formed in a cylinder block, and surround periphery of an injector fixing part (53). An upper edge of a water jacket spacer (3) disposed in a block-side water jacket is provided with projections (34) projecting toward the recessed coolant passage (55B) so as to direct at least part of the coolant flowing through the intake-side water jacket part (22a) toward the recessed coolant passage (55B). With this, it is possible to suppress decrease in flow rate of the coolant due to disturbance caused to the coolant flow flowing along the periphery of the injector fixing part (53), to thereby provide a sufficient cooling performance for an injector.
