    摘要： This two-stroke cycle is applicable at classical internal combustion engines (piston-rod-crankshaft) as well as at engines with two-sided piston. The very systems has at least one pair of cylinders (1, 2) of which one (1) is compresor (pump) and other (2) is engine. The compressor and the engine pistons (3, 4) have such phase delay to each other that when one piston is in the midpoint between two 'dead points' of the engine, other is in one of 'dead points'. At the moment when the compressor piston (3) has passed half the way from LDP to UDP, it also has precompressed the sucked air, while the engine piston (4) is at LDP and has opened the exhausting channel (15), which leaves out the combustion gas. Because of the higher pressure in the compressing pipe relating to the pressure in engine cylinder (2), the inlet valve (7) of the engine opens and fresh air enters the engine. When the compressor piston (3) comes at UDP, it delivers all the air to the engine and spring force closes the inlet valve (7) of the engine. In the meantime the engine piston (4) has closed the exhausting channel (15) and the injector (11) has injected the fuel into the engine cylinder (2). The engine piston (4) keeps on compressing the air-fuel compound until the UDP has reached. The sparking plug (13) starts the ignition, while the compressor piston (3) goes towards LDP sucking the air. The cycle is repeating.

    摘要： A two stroke combustion engine comprising at least one combustion cylinder (13) having a cylinder center axis (19), a combustion piston (12) movable within the combustion cylinder (13), the combustion piston (12) having a first compression direction (CD) along the cylinder center axis (19). The two stroke combustion engine further comprising at least one separate piston pump (3a) having a piston pump cylinder (3b) with a piston pump center axis (20b) and a pump piston (25) movable within the piston pump cylinder (3b). The separate piston pump (3a) is in movable mechanical connection (18) with the combustion piston (12). The two stroke combustion engine further comprising an air inlet (10) having an air inlet center axis (20a). The separate piston pump (3a), the air inlet (10) and the combustion cylinder (13) are in fluid connection with each other by a transfer channel (11), and the piston pump center axis (20b) intersects a cylinder plane (X-19) extending from the cylinder center axis (19), and the intersection defines a ray (19') extending from the intersection in the first compression direction (CD). A normal axis (N) extends perpendicularly from the cylinder plane (X-19), the normal axis (N) intersects the piston pump center axis (20b). An angle, measured from the intersection between the ray (19') and a point on the piston pump center axis (20b), located in the piston pump cylinder (3b), is between 30° and 160°.

    摘要： A two-stroke engine includes a crankcase (34). A power cylinder (14) extends from the crankcase (34). The power cylinder (14) selectively fluidly communicates with the crankcase (34) to scavenge the power cylinder (14). A power piston (22) is reciprocably disposed in the power cylinder (14). A compressor cylinder (18) extends from the crankcase (34). The compressor cylinder (18) selectively fluidly communicates with the power cylinder (14) to introduce a pressurized air/fuel mixture into the power cylinder (14). A compressor piston (24) is reciprocably disposed in the compressor cylinder (18).
