Abstract: The two-stroke engine has a plurality of intake passages extending from the external air inlet port through the crankcase, separating the intake air charge from the air and oil vapor within the crankcase. The piston has one or more corresponding inlet tubes depending therefrom that telescope within the crankcase intake passages as the piston reciprocates. All intake air travels through these passages and is separated from the remainder of the crankcase volume. The incoming air charge passes through a concentric poppet valve in the piston crown to enter the combustion chamber. Fuel is provided by conventional direct or port injection and ignition is provided by one or more conventional spark plugs. Diesel operation is achievable when the engine is configured appropriately. Exhaust exits the combustion chamber through a poppet valve in the cylinder head, the poppet valve being actuated by a rocker arm and pushrod from a crankshaft driven cam.

Abstract: In an attempt to regenerate energy of exhaust gas by using a pressure regenerator secured to an exhaust port of a displacement type engine so as to realize the Atkinson's cycle, if the engine is a four-cycle engine, raising regenerative pressure may cause abnormal fuel combustion or melting damage of an exhaust valve. The present invention has successfully solved this problem by using a six-cycle engine. The six-cycle engine with a regenerator according to the present invention is capable of varying proportion of the power output that is generated by the six-cycle engine itself and that is generated by the regenerator. Using this principle enables the six-cycle engine with a generator to be used as an engine that is capable of generating two kinds of output power or as a six-cycle gas turbine with high controllability. The invented internal combustion engine is excellent and valuable in the fuel cost economy when it is used as a motor for a power station and a small generator as well as a motor for a movable body such as a ship or a vehicle. The invented internal combustion engine is especially suitable for a movable body such as a hybrid-system vehicle. Incidentally, the inventor is ready for granting the rights for practicing the present invention.

Abstract: A six-cycle engine has the advantage for the capability of internal cooling with scavenging air. This advantage enables the compressive ratio to rise, thereby achieving lower fuel consumption. However, there has been a critical problem due to lowered temperature of the exhaust catalyst and excessive volume of oxygen contained therein caused by the mixing of the scavenging air with exhaust gas. To solve the problem of lowered temperature, the invention has thermally insulated the fuel combustion chamber and the exhausting system, and controlled the aperture degree of the scavenging port valve relatively to the suction valve to adjust the scavenging air volume against the suction air, thereby controlling temperature of the exhaust gas. Further, to solve the problem of excessive volume of oxygen, the invention has introduced an EGR (Exhaust Gas Recirculation) system to fully substitute the scavenging air with circulating exhaust gas and a self EGR system to open the exhaust valve during the scavenging air introduction stroke. The present invention has successfully made a naturally good fuel-efficient six-cycle internal combustion engine be suited one for practical use such as conventional vehicles.

Abstract: A two-stroke engine has a piston, mounted to be displaced in a cylinder, connected by means of a connecting rod to a crankshaft mounted to rotate about an axis in a crankcase that defines a crankcase chamber. The crankshaft includes a crankshaft duct that opens into the crankcase chamber which is, depending on the angle of rotation of the crankshaft, connected by way of an inlet opening in the crankshaft to an inlet manifold for an air/fuel mixture. The cylinder includes a transfer port, by way of which, the air/fuel mixture flows from the crankcase chamber past the piston into the working chamber based on the position of the piston in the cylinder. An increase in engine power is achieved by a gas mixing duct, a slot or a deflecting element arranged within the crankcase which improve(s) the filling of the crankcase chamber with the air/fuel mixture.

Abstract: This invention relates to novel reciprocating shuttle inlet valves, effective with every type of two-cycle engine, from small high-speed single cylinder model engines, to large low-speed multiple cylinder engines, employing spark or compression ignition. Also permitting the elimination of out-of-phase piston arrangements to control scavenging and supercharging of opposed-piston engines. The reciprocating shuttle inlet valve (32) and its operating mechanism (34) is constructed as a single and simple uncomplicated member, in combination with the lost-motion abutments, (46) and (48), formed in a piston skirt, obviating the need for any complex mechanisms or auxiliary drives, unaffected by heat, friction, wear or inertial forces. The reciprocating shuttle inlet valve retains the simplicity and advantages of two-cycle engines, while permitting an increase in volumetric efficiency and performance, thereby increasing the range of usefulness of two-cycle engines into many areas that are now dominated by the four-cycle engine.
