An internal combustion engine that completes four cycles, intake, compression, expansion and exhaust in one revolution of the crankshaft is disclosed. The combustion chamber is formed with four parallel vanes joined at their ends by shared bearings and pivot pins within two fixed parallel walls. The vanes lozenge across alternate corners of the chamber to change the volume defined by the four moveable vanes and the two fixed parallel walls. The chamber volume changes from a minimum to a maximum to a minimum and back to the original maximum to achieve four cycle operation with one crank shaft revolution. The crankpin may have two side by side connecting rods rotating each of the adjacent driven vanes. The driven vanes may be connected about a common shared pivot pin that extends into the fixed side walls and the other two interconnected follower vanes may be driven in rotation and translation about their shared and common pivot pins.

A variable volume chamber device is disclosed. The chambers may be defined by the space between four pivotally connected vanes contained within a housing. The vanes may be connected so as to create a sealed interior chamber that may be used as a combustion chamber in an internal combustion engine, or as a pumping chamber in a pump or compressor. The four-vane assembly may also form additional variable volume chambers between the vanes and a surrounding structure. The plurality of variable volume chambers may be interconnected to progressively act on a working fluid.

Variable volume chamber devices are disclosed. The chambers may be defined by the space between two complementary rotors. The volume of the chambers may vary as a function of the variation of relative rotational speeds of the two rotors.

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.
