Abstract: In order to improve a hand-guided appliance with a two-stroke internal combustion engine with direct electronic fuel injection in such a way that the fuel injection is optimised, it is proposed to fit a partition (19) bordering the cylinder (15) which separates the adjacent intake chamber from the cooling air guide and to fit the fuel injection valve (17) above the intake port of the cylinder (15) passing through the partition (19).

Abstract: A compound engine (10) that includes a gas turbine unit (36) and a piston unit (12) wherein the cycle air for the piston unit is diverted through cooling passages (152, 158, 168, 174, 178, 184, 196, 210, 220, 228) to provide impingement cooling of several areas of the piston unit including the upper cylinder area (161), the outer and inner surfaces of the exhaust valve (190, 203) and other selected areas of the cylinder head (173, 222).

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.
