Abstract: A gas feeding arrangement for feeding gas from an internal combustion engine cylinder chamber to a gas tank includes a feeding conduit assembly and a dedicated feeding valve. The feeding valve is adapted to assume an open condition in which it provides for gas transport in a direction from the cylinder chamber towards the gas tank, via the feeding conduit assembly. The gas feeding arrangement includes a one-way valve adapted to prevent gas transport from the gas tank to the cylinder chamber, via the feeding conduit assembly.

Abstract: Internal combustion engines having multi-stage telescoping poppet valves in lieu of conventional poppet valves are disclosed. The engines may have pistons with a skirt with a field of pockets that provide a ringless, non-lubricated, seal equivalent. The piston heads may include one or more depressions and may be domed to facilitate the movement of air/charge in the cylinder. The engines may also have non-circular, preferably rectangular, cross-section pistons and cylinders. The engines also may include a split crankshaft. The engines may use the pumping motion of the engine piston to supercharge the cylinder with air/charge. The engines also may operate in an inverted orientation in which the piston is closer to the local gravitationally dominant terrestrial body's center of gravity at top dead center position than at bottom dead center position.

Abstract: A valve arrangement for supplying air to a combustion chamber of an internal combustion engine includes a first valve, the first valve including a first valve head, a first valve stem assembly and an internal cavity, which is at least partly located in the first valve stem assembly, and a second valve partly arranged within the internal cavity of the first valve, the second valve including a second valve head and a second valve stem assembly, and being movable within the internal cavity between an upper, closed position and a lower, open position, wherein a junction seal extends over a junction between the first valve stem assembly and the second valve stem assembly when the second valve is in the closed position. A leakage preventing arrangement is arranged to hinder leakage of liquid from the outside of the junction seal from reaching in between the first valve stem assembly and the second salve stem assembly.

Abstract: A cylinder head assembly for an internal combustion engine having an intake cycle and an exhaust cycle is provided. The cylinder head assembly includes a single valve, a cylinder head body, and a venturi tube. The cylinder head body has an intake port, an exhaust port, and a combustion chamber port configured to intermittently seat the single valve. The venturi tube is disposed within the cylinder head body and has a high pressure portion operably coupled to the cylinder head body proximate the intake port and a distal end spaced apart from the combustion chamber port. The venturi tube permits the intake port to remain in fluid communication with the exhaust port during both the intake cycle and the exhaust cycle of the internal combustion engine.
