    摘要: A cylinder head (2, 2A, 2B, 2C) includes a water jacket (6, 6A, 6B, 6C). The water jacket includes multiple coolant spaces between combustion chambers (4, 4a, 4b, 4c, 4d) adjacent. The multiple coolant spaces include a high-pressure space (30, 32, 34, 70, 72, 74, 100, 102, 104, 130, 132, 134) having relatively high internal pressures and a low-pressure space (31, 33, 71, 73, 101, 103, 131, 133) having relatively low internal pressures. The high-pressure space and the low-pressure space are alternately arranged with each other. The water jacket includes a first lateral passage (41, 42, 43, 44, 81, 82, 111, 112, 141, 142) passing through the low-pressure space and extending in the lateral direction of the cylinder head, and a communication passage (36, 37, 38, 39, 76, 77, 78, 79, 106, 107, 108, 109, 136, 137, 138, 139) passing between an intake valve hole (11, 12) and an exhaust valve hole (13, 14), and allowing the high-pressure space and the low-pressure space to communicate with each other. A coolant outlet (51, 88, 118, 148) is connected to the first lateral passage. The coolant inlet (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 90, 92, 94, 120, 121, 122, 123, 150, 151, 152, 153) is connected to the communication passage or the high-pressure space.

    摘要: A pre-combustion chamber unit (57) that has a hollow shape elongated along a longitudinal axis (53) for providing a pre-combustion chamber (59) comprises a pre-combustion chamber wall (67) delimiting the pre-combustion chamber (59). The pre-combustion chamber wall (67) comprises a main section (67A) at least partly surrounding an ignition portion (59A) of the pre-combustion chamber (59), a tip section (67B) forming a pre-combustion chamber tip section (63) of the pre-combustion chamber assembly (50), and a seal section (67C) in-between the tip section (67B) and the main section (67A) for providing a seal region (73) in the mounted state. The main section (67A) comprises an external fluid guiding surface (81A) circumferentially extending around the longitudinal axis (53) and being curved along and towards the longitudinal axis (53) for smoothly redirecting a cooling fluid. Thereby the cooling may be improved.

    摘要: A water jacket for a cylinder head of an internal combustion engine includes a coolant chamber arranged to permit the flow of coolant within the water jacket and a coolant conduit positioned to permit the flow of coolant proximate to a recess for receiving an exhaust valve mounted to the cylinder head. The coolant conduit is in fluid communication with the coolant chamber, and the coolant conduit is shaped as a complex curve. A water jacket includes a pair of apertures arranged to receive a spark plug and a fuel injector. The apertures are separated by a separating member, and a coolant chamber is arranged to permit the flow of coolant about the apertures. The separating member includes a coolant channel in fluid communication with the coolant chamber so as to permit the flow of coolant between the apertures.
