    Abstract: A method of connecting aluminium or aluminium alloy to another metal material in which the other metal material (13) is connected first to a porous metal material (12). This may be by brazing or welding. This assembly is then placed in a die and the aluminium or aluminium alloy (10) is fed under gravity to the die and then solidified under pressure in a squeeze casting technique. The aluminium or aluminium alloy (10) penetrates the porous metal material (12) so that, on solidification, the aluminium or aluminium alloy (10) is firmly connected to the other material (13). This can find particular application in the manufacture of pistons for internal combustion engines where the piston body is of aluminium of aluminium alloy and a wear of heat-resistant insert is of ferous material. The insert may form a crown of the piston or an expansion control insert or a piston ring groove or an entrance to a combustion bowl or a combination of these features.

    Abstract: An internal combustion engine (10) comprising an engine frame (12) having a drive shaft (20) rotatably mounted therein and extending outwardly therefrom. A pair of cylinder sleeves (40, 40') are mounted on the engine frame (12) and have their inner ends positioned within the interior of the frame and their outer ends positioned outwardly thereof. A cylinder head (60, 60') is secured to the outer end of each of the sleeves and is separated thereby by means of a heat insulative gasket (70). Each of the cylinder heads (60, 60') has a dome-shaped chamber (62, 62') formed therein which is in communication with a source of combustible fuel. An air inlet conduit (94) is mounted on one end of the engine frame and is in communication with a source of air under pressure such as a blower, super-charger or the like. The air inlet conduit is in communication with an air passageway (100) formed in the engine frame (16) which is in communication with air inlet openings (52, 52') formed in the cylinder sleeves (40, 40'). The cylinder sleeves (40, 40') are provided with exhaust openings (54, 54') formed therein which communicate with an air exhaust passageway (102) formed in the engine frame (16). The exhaust passageway (102) is connected to exhaust conduit (106) or pipe extending from the engine frame (16). A piston (72, 72') is slidably mounted in each of the sleeves (40, 40') and has a dome-shaped head portion (76, 76') which is adapted to be received by the dome-shaped chamber (62, 62') in the cylinder head (60, 60') when the piston is in its top position. In the top position, the small "air space" (118) is present between the walls or sides (78, 78') of the piston head (76, 76') and the walls or sides of the sleeves (64, 64'). The "air space" (118) serves as a means for retarding the absorption of heat into the sides of the piston head (76, 76') and the sides of the cylinder sleeve (40, 40'). In the down position, the "air space" (118) also serves to spread the cooling air into a thin, wide sheet for more efficient cooling of the cylinder head (60, 60') and sleeves (40, 40'). Optional air deflecting fins (84, 86, 84', 86') may be employed on the piston head (76, 76'). The rings (82, 82') of the piston (72, 72') are conventionally lubricated and slide upon the interior wall (52, 52') of the cylinder sleeve (40, 40'). Each of the pistons (72, 72') has a roller (88, 88') mounted on the skin portion (74, 74') thereof which rolls upon a cam (32) mounted on a rotor plate (30) which is secured to the drive shaft (20) for rotation therewith. A return roller (92, 92') is also operatively mounted on the skin portion (74, 74') of the piston (72, 72') for engagement with a return cam (36) which is mounted on the drive shaft (30) for rotation therewith.
