摘要： A rotary cylinder machine, designed as a two-cycle internal combustion engine or as a compressor, includes in a housing (1) a cylinder rotor (5) that rotates about a first axis of rotation (7) and has three pairs of cylinders (13), the cylinders of each pair being coaxial and on opposite sides of the first axis of rotation and the pairs being spaced apart circumferentially by 120.degree.. The radially outer ends of the cylinders are closed by cylinder covers (33). Three pairs of pistons (15), rigidly connected together by piston rods (17), are carried on a crankshaft (21) that is rotatable about a second axis of rotation (23) that is parallel to and eccentric to the first axis of rotation (7). The piston rods (17) are seated on three eccentric disks (25), likewise displaced 120.degree. with respect to one another, on the crankshaft (21). Gas exchange takes place through piston-controlled ports (51, 53) of the cylinders (13). In the gas-exchange path of the ports (51, 53) rotary slide valve control arrangements (57), which optionally control gas exchange together with the piston-controlled ports (51, 53), are provided on at least the exhaust side. Gas intake may take place through rotary slide valve controls, or through an intake channel terminating in a crankshaft chamber of the cylinder rotor (5) and connected with the intake ports by overflow channels. In an internal combustion engine, a blower driven by a variable-speed motor may be provided for control of the degree of filling of the combustion chambers (37).

摘要： A two-cycle internal combustion engine is provided which comprises: a cylinder receiving a reciprocative piston and having a top portion provided with a combustion chamber in which a spark plug faces; an exhaust port laterally opening into the cylinder; at least one first scavenging port opening into the cylinder at one side of the exhaust port; and at least one second scavenging port opening into the cylinder at another side of the exhaust port opposite to said one side. Each of the first and second scavenging ports directs scavenging gas away from the exhaust port. The first scavenging port opens into the cylinder with an upward inclination for directing a first portion of the scavenging gas upwardly toward the top portion of the cylinder, whereas the second scavenging port is oriented to direct a second portion of the scavenging gas transversely of the cylinder toward a wall portion of the cylinder where the first scavenging port is formed.

摘要： A two cycle crankcase compression diesel engine having a supplemental exhaust port system that is formed in a straight line perpendicular to the cylinder bores and which intersects the main exhaust ports. An exhaust control valve arrangement is provided for controlling the flow through the supplemental exhaust ports to reduce the compression ratio under high load, high speed running conditions. The supplemental exhaust control valves comprise a plurality of individual valves each contained within a common bore extending through the cylinder and interconnected by connecting members that permit axial and circumferential misalignment so as to accommodate for distortion and avoid sticking of the valves.

摘要： A two stroke engine having an exhaust port formed in the cylinder wall. At the upper portion of the exhaust port, there is provided a rotary type exhaust timing control valve which is adapted to be rotatably actuated to control the exhaust timing in accordance with the engine speed. The control valve is interconnected with the engine starting mechanism so that the control valve is forcedly driven by the starting mechanism to thereby eliminate valve seizure.
