摘要： A cylinder housing (1) is cast with a cylinder wall (2) in the making of a cylinder for an internal combustion engine. The cylinder wall delimits an interior space (3) for accommodating a reciprocating piston and, thereafter, a control window (5) is machined into the cylinder wall (2) as an opening of a transfer channel (4) into the interior space (3). A two-stage machining for forming the control window (5) is provided in order to make possible a rapid and cost effective manufacture of the cylinder. In a first step with a work tool (7) having a rotating primary movement (11), a breakthrough (10) is machined into the cylinder wall (2) and, in a second step with a work tool, the breakthrough (10) is widened to the wanted dimensions of the control window (5).

摘要： A cylinder block has a number of cylinder bores and a water jacket at least partially surrounding the bores. When casting a cylinder block the water jacket is formed by a slender wall of a sand core. To enable the wall to be removed from the core box the wall must taper over its entire height. Prior art water jackets therefore taper from a minimum sand core wall width at the base to a large width at the top. The cylinder block of the invention has a water jacket which, when viewed in transverse section, is wider in an intermediate portion than at either its top or base. In providing a water jacket which is narrower at the top, there is more room for the addition of machined features on the top deck. Furthermore, a water jacket which is narrower at the base can have a greater depth than conventional water jackets.

摘要： A precision cooling system directs the flow of coolant to optimize coolant flow around the cylinders of an internal combustion engine. This results in lower temperatures in the upper portion of the cylinders, more uniform temperatures throughout the engine, and a lower average temperature. The precision cooling system is integrated into the construction of the water jacket distributing coolant throughout the engine and particularly around the combustion cylinders.

摘要： An outboard motor includes a housing unit adapted to be mounted on an associated watercraft. An engine is mounted on the housing unit. The housing unit defines a water delivery passage and a water discharge passage. Both the passages communicate with each other through a lower opening. The water delivery passage is arranged to deliver cooling water to the engine. The water discharge passage is arranged to discharge the cooling water from the engine. The discharge passage communicates with a location out of the housing unit through an upper opening. A pressure relief valve unit extends through the lower and upper openings. The pressure relief valve unit allows the cooling water in the delivery passage to move to the discharge passage when a pressure of the delivery passage becomes greater than a preset pressure.

摘要： The present invention relates to multiple integrated fluid passages for a internal combustion engine which allow for economical and convenient means for routing fluids in relation to an engine block. For example, the molded passages of the present invention allow coolant to be applied directly to areas needing heat transfer, without requiring the provision of large areas in the engine block to accommodate such cooling fluid. Also, the molded passages of the present invention do not require circular internal passages, so that space-critical items can receive proper distribution of fluid. Also, the molded passages of the present invention allow for economical velocity control of fluids by controlling the sizes of the fluid passage. In a preferred embodiment, the molded passages are formed in a clam shell configuration having an open side and are attached to an exterior surface of the cylinder block, thereby forming an enclosed pathway for fluid flow.

摘要： A method of manufacturing a cylinder for an internal combustion engine, which is manufactured by a process wherein a raw cylinder body having an insert core left remained therein is obtained using an insert core comprising a cylindrical body having almost the same outer diameter as the diameter of bore of the cylinder, and a scavenging port-forming portion projecting radially outward from the cylindrical body and having almost the same cross-sectional configuration as that of the scavenging port, the cylinder bore of the raw cylinder body thus obtained is then subjected to a boring to remove the cylindrical portion of the insert core, and the scavenging port-forming portion of the insert core which is left remained in the raw cylinder body is removed by making use of a press.

摘要： A cylinder block for a water-cooled internal combustion engine has a top deck, a cylinder wall structure defining a row of cylinder bores, and a water jacket wall structure defining a water jacket around the cylinder bores. The jacket wall structure has a plurality of cylinder head bolt bosses each formed with a bolt hole for a cylinder head bolt for fastening a cylinder head on the top deck of the cylinder block. At least one of the head bolt bosses is a terminal head bolt boss which is formed at an end portion of the cylinder block, and which is connected, by a rib, with the cylinder wall structure and the top deck to prevent stress concentration and cracks.
