摘要： A nozzle of a piston cooling system includes a flow path defined by a structure of the nozzle and configured to receive a cooling fluid, a first flow opening fluidly coupled with the flow path and extending through the structure of the nozzle, and a second flow opening fluidly coupled with the flow path and extending through the structure of the nozzle. The first flow opening and the second flow opening are sized to enable laminar flow of corresponding first and second jets of the cooling fluid discharged through the first and second flow openings, respectively.

摘要： A piston for diesel engines includes a piston body having a closed oil gallery and a pair of pin bosses with axially aligned pin bores. The inner faces of the pin bosses are separated from one another by an intervening space between the pin bosses for receiving the upper end of a connecting rod, which has associated outer faces adjacent the inner faces of the pin bosses. Oil passages extend from the gallery and open to the inner faces of the pin bosses for providing direct lubrication to the inner faces.

摘要： A piston cooling structure includes a cylinder block (1) and a cooling medium supplying device (20). The cylinder block (1) includes a cylinder bore (1a) and an inter-bore wall (2) at least partially forming the cylinder bore (1a). The cooling medium supplying device (20) is mounted to the inter-bore wall (2) to supply a cooling medium into the cylinder bore (1a). The inter-bore wall (2) has a bearing support portion (2b), a through opening (15) and an internal passageway (16). The through opening (15) communicates with the cylinder bore (1a) and extending in a direction parallel a rotational axis of the crankshaft (6). The internal passageway (16) extends from the bearing support portion (2b) to the through opening (15) in a direction parallel to a center reciprocation axis of the cylinder bore (1a). The cooling medium supplying device (20) is fluidly connected to the internal passageway (16) with an injection part (20a and 20b) being arranged with respect to the through opening (15) to supply the cooling medium from the injection part (20a and 20b) to the cylinder bore (1a).

摘要： The invention relates to a device for cooling the pistons of an internal combustion engine, by means of a lubricating oil pump supplying oil to each piston, at least on the bottom face thereof, from the lubricating oil circuit, by means of a supply line comprising an outlet opening, whereby oil supply is achieved through at least one valve. According to the invention, the at least one valve is a non-return valve, which permits a supply of oil only when a defined pressure in the lubricating oil circuit is achieved, provided with a controller, which guarantees that the lubricating oil pump is controlled such as to provided a variable pressure in the lubricating oil circuit, under differing operating conditions for the internal combustion engine depending on load.

摘要： A piston assembly includes a piston head having an open bottom cooling gallery and a pair of pin bosses depending from the head and supporting a wrist pin of a connecting rod. A skirt (14) is coupled to the pin bosses for reciprocation with the piston head. A stationary oil spray nozzle (38) extends into the piston skirt (14) from below and cooperates with an oil splash deflector (58) which, at a lowered position of the piston head, directs the flow of oil (L) onto the pin bosses for direct cooling, and at raised position of the piston head, moves out of the way to allow the cooking oil (L) to enter the cooling gallery and cool the piston head.

摘要： Object: In a piston cooling structure for a multicylinder engine having oil jets for ejecting oil toward pistons, mounted in those of a plurality of journal walls except one journal wall, by which a crankshaft is rotatably supported, to be able to supply oil to a cylinder head in a position closer to a central region along the axis of the crankshaft while avoiding a complex oil passage shape.
Solving Means: An oil passage (65) for guiding oil to a cylinder head is defined in one of journal walls (22B, 22C, and 22D) disposed between pairs of adjacent ones of the cylinder bores (20), of all journal walls (22A through 22E), and oil jets (64) are mounted in the journal walls except the journal wall with the oil passage (65) defined therein.

摘要： A duct (35; 135; 235) from near the top of the skirt (30) of a two-piece piston (10) carries lubricant to the skirt pin bore (34), on each side of the skirt, and lubricates the pin joint (70). The skirt (30) is provided with a lubricant passage (35; 135; 235), such as from a shaker tray (33; 133; 233), to the pin bore (34, 134; 234) on each side of the pin joint of the skirt (30), piston crown struts (27), and wrist pin (40) on which a piston connecting rod (50) is joined. Fluid sprayed against the crown (20) descends onto the skirt (30) and some passes through the above-mentioned lubricant ducts or passages (35; 135; 235) for direct, continuous lubrication of the pin joint (70).
