    Abstract: The invention relates to a gas-exchanging process for two-stroke internal combustion engines, and a two-stroke internal combustion engine for executing the process, in which two scavenging paths of the gas are provided, namely the known reverse scavenging as the first scavenging path, and a second supply of combustion air effected by precompression serving as the second scavenging path, wherein during the second scavenging an ignitable fuel-air mixture forms in the area of the point of ignition and, by means of the differential pressure established at the intake valve, controls the mixture as well as the quantity itself.

    Abstract: A valve mechanism for a reciprocating piston internal combustion engine having one large poppet valve per cylinder communicating with both inlet and exhaust tracts. A partition between the inlet and exhaust tracts has gas flow ports therethrough moving into and out of alignment with similar gas flow ports in the valve stem. The ports are arranged to permit gas flow from the inlet tract to the outlet tract when the valve is closed.

    Abstract: An intake port pressure control system comprises an intake passage leading to a cylinder in an engine, and a check valve in the intake passage to allow fluid flow toward the cylinder and obstruct fluid back-flow in the reverse direction. A bypass port is located on the intake passage so that the bypass port communicates with a trapped volume defined by the portion of the intake passage between the check valve and intake valve. The intake port pressure control system further comprises a control valve having an outlet passage, a secondary passage, and an actuator enabling communication between the outlet passage and secondary passage. The actuator further enables active adjustment of the flow area of the flowpath between the secondary passage and outlet passage throughout a range of engine operating conditions. The outlet passage is connected to the bypass port, and the secondary passage is connected to a secondary air source. The control valve enables a controlled air flow therein between the secondary air source and the trapped volume when the intake valve is closed.

    Abstract: A four stroke combustion engine and method of operation of use and control is disclosed. The engine includes a combustion chamber with an intake manifold coupled to the combustion chamber. A one-way valve (22) is located within the intake manifold. The engine includes an intake valve (10) for modulating the flow of a fuel-air mixture into and out of the combustion chamber. The engine preferably employs a fixed, late closing intake valve. A plenum chamber (20) is located in the intake manifold. The plenum chamber is located downstream of the one-way valve and upstream of the intake valve. During the compression stroke of the engine, a pressurized charge of fuel-air mixture is stored within the manifold and plenum. The amount of the fuel-air mixture stored within the plenum is controlled by adjusting the volume of the plenum, or, alternatively, a plenum valve (34) is used to regulate the amount of fuel-air mixture entering/exiting a fixed volume plenum.

    Abstract: Internal combustion engine, with cylinders' body (1) being an individual component, separate from the crankshaft base (29), thus enabling it to move and the cylinder head (3) of which features a common induction-exhaust valve (4) per cylinder, driven by a cam (5), and two secondary auxiliary valves (7), (8), or alternatively (19), (20) per cylinder, for the assistance the main valve during the induction and exhaust strokes. Each engine cylinder (1) has a port (26), at a specified height, where a displacement variation valve (25), and alternatively (27), is mounted, through which a controllable amount of air escapes, during compression as well as when a displacement variation is desired. With the common induction-exhaust valve (4), the compression ratio can be increased to high levels, since this valve is sufficiently cooled, thus preventing the occurrence of self-ignition. With the displacement variation valve, the engine's displacement and, consequently, its fuel consumption and emission level can be reduced, when desired. With the upward and downward movement of the cylinders' body, the combustion area is increased and decreased respectively, and therefore, the combustion ratio is altered, regardless of the displacement.
