Abstract: An intake system mounted to a vehicle controls an opening angle of a variable flap according to an RPM of an engine, an intake pressure, and an opening angle of a variable flap to optimize performance in various operation regions by detecting engine RPM and an intake air pressure, and determining an operation region based on the RPM of the engine; applying the intake pressure to determine a target amount of air and an opening angle of a variable flap for an operation region; driving an actuator to adjust an opening angle of the variable flap to a target opening angle; and analyzing an operation position of the actuator to detect an opening angle of the variable flap, and, when the target opening angle is not followed, correcting a drive of the actuator such that an opening angle of the variable flap follows the target opening angle.

Abstract: A combustion chamber of an internal combustion engine has primary intake ports located a first distance from the crankshaft and primary intake ports located a second distance from the crankshaft. One or more unidirectional valves, such as reed valves, are place in an intake duct upstream of the primary intake ports. The valves prevent backflow from the cylinder into the intake when the pressure in the cylinder exceeds that of the intake. The backflow into the intake is reduced by having valves in the intake; therefore scavenging efficiency is improved. Furthermore, the asymmetry between the intake and exhaust port timing may be reduced by providing such valves. Additionally, the total intake port area can be increased with two sets of intake ports and valves disposed in the primary ports, thereby improving the volumetric efficiency in spite of the pressure drop presented by the valves.

Abstract: A two-stroke engine includes a crankshaft that is rotatable about an axis, and an engine block that includes a combustion cylinder and a compression cylinder. A first piston is slidably disposed within the combustion cylinder and is operatively coupled to the crankshaft for reciprocating movement within the combustion cylinder through a power stroke during each rotation of the crankshaft about the axis. A second piston is slidably disposed within the compression cylinder and is operatively coupled to the crankshaft for reciprocating movement within the compression cylinder such that fresh air is received and compressed in the compression cylinder during each rotation of the crankshaft about the axis. A conduit provides fluid communication between the combustion cylinder and the compression cylinder, and a fuel injector is in communication with the combustion cylinder for admitting fuel into the combustion cylinder.

Abstract: A device that injects hydrogen gas into an engine's air intake or intake manifold that is demand controlled by the vehicle's throttle linkage in an approximately linear manner. When the throttle is depressed, hydrogen generation can start or increase, and when the throttle is released, hydrogen generation can stop of decrease. The device of the present invention uses the vehicle's own vacuum to control the production of hydrogen by forcing a liquid to rise in a chamber and into contact with metal in response to increasing vacuum thus producing an increasing amount of hydrogen gas with increasing throttle depression.

Abstract: The hybrid multi-power stroke engine is an improved internal combustion engine that includes a steam engine integrated into the design, which derives power from heat generated at the combustion chamber as well as exhaust manifold of the internal combustion engine. The steam engine injects and exhausts superheated steam directly into the cylinder on a 5th and 6th stroke thereby alternating the engine from internal combustion to steam. A water tank is in fluid communication with a water pump and piping that passes across the cylinder block whereby heat is removed therefrom. The piping is in fluid communication with an exhaust manifold that transfers superheated steam to an electronic steam intake valve that injects the superheated steam on a 5th stroke. An auxiliary camshaft opens an exhaust steam valve on a 6th stroke in order to exhaust the expanded steam from the cylinder.
