摘要： The invention relates to a piston (1) for an internal combustion engine, configured as a gallery-cooled piston of two-piece construction which comprises a main body (2) and a ring element (3). The ring element (2) which has a ring zone (18) and a fire land (17) encloses a cooling gallery (15) on the outside, which cooling gallery (15) is delimited on the inside by an intermediate wall (16) which separates the cooling gallery (15) from a combustion-chamber recess (12) which is made in a piston head (10) of the main body (2). The main body (2) and the ring element (3) together form two circumferential dividing planes (4a, 5a) which are offset with respect to one another, to which end in each case two interacting joining webs (6a, 6b; 7a, 7b) of the ring element (3) and of the main body (2) are connected with a material-to-material bond.

摘要： A body (2) of an oil jet (100) is provided with: an oil supply port (6) which opens into an oil passage (62) in a cylinder block (60) of an internal combustion engine; a cylinder (4) one end of which is communicated with the oil supply port (6) and the other end of which is closed; and an oil injection port (10) which opens on a side surface of the cylinder (4). A piston valve (20) is accommodated in the cylinder (4). The piston valve (20) forms in the cylinder (4) a differential pressure room (8) which is a closed compartment. Moreover, an orifice (22) which makes the differential pressure room (8) being communicated with a side of the oil supply port (6) is formed in the piston valve (20). The piston valve (20) is biased toward a position at which the oil injection port (10) is closed by a spring (14). Furthermore, a leak hole (42) which allows oil to be leaked outside of the body (2) from the differential pressure room (8) is formed in the body (2).

摘要： A two-cycle, opposed piston engine with side-mounted crankshafts and cylinders isolated from mechanical stresses of the engine includes tailored cooling of cylinders and symmetrical cooling of the interior surfaces of piston crowns. Each opposed piston includes a compliant member that permits movement of an axially-centered rod mounted in the piston in order to maintain axial alignment with the bore of a cylinder in which the piston is disposed during engine operation. A single wristpin is disposed externally of the piston to connect the piston with connecting rods that run between the piston and the crankshafts.
