Abstract: A combustion engine has a combustion chamber separated from the compression and expansion chamber(s). Passages are provided between the combustion chamber and the compression chamber(s) and the combustion chamber and the expansion chamber(s) with respective valves in the passages and inlet and exhaust valves provided in the combustion and expansion chamber. The combustion chamber maintains the combustion after passing fuel into the compressed air received from the compression chamber. The valves and piston heads are formed to prevent dead space in the cylinders in order to obtain a good efficiency by full discharge of the compressed air into the combustion chamber. Fuel cleaning means like, for example, a rotary separator and pure gas collecter are provided in the combustion chamber to separate unclean fuel particles, as, for example, ash or sand in coal, from the burned gases and collect the unclean particles in separated collection spaces. The engine can thereby burn unclean fuels, as for example coal powder or coal sludge and the like. The valves can be timed for different styles of combustion cycles if so desired. The engine may use conventional four stroke or two stroke engine arrangements and provide them with combustion chambers, pistons and cylinder heads of the invention to modify them from gasoline combustion to coal combustion or other cheaper and more avialable fuels for the combustion in the compressed air.

Abstract: The present invention relates to a reciprocating internal combustion engine with a high fuel efficiency and a low level of emissions. This is achieved by structural measures that improve the combustion process, including but not limited to the incorporation of an impeller or other fluid mixing device inside the combustion chamber and the use of annular intake and/or exhaust valves.

Abstract: An intake and exhaust valve system (10) for an internal combustion engine having a combustion chamber (19) within a cylinder (13) closed at one end by a cylinder head (17). A cavity (25) is provided in the cylinder head opening onto the combustion chamber through a first port (27). The valve system (10) has first and second valves one of which is an intake valve (31) movable between open and closed conditions for controlling intake fluid flow into the combustion chamber (19) and the other of which is an exhaust valve (33) movable between open and closed conditions for controlling exhaust gas flow from the combustion chamber. The first valve (31) comprises a valve head (35) sealingly engagable with the first port (27) and a skirt structure (37). The skirt structure (37) is in sliding and sealing engagement with a tubular wall structure (49) within the cavity (25) whereby the skirt structure and wall structures cooperate to divide the cavity (25) into an inner cavity section (51) and an outer cavity section (53) surrounding the inner cavity section. A first flow passage (26) communicates with the outer cavity section (53) and a second flow passage (28) communicating with the inner cavity section (51). The second valve (33) is disposed in the first valve (31) for opening and closing a second port (61) in the first valve (31) for controlling fluid flow between the combustion chamber (19) and inner cavity section (51) wherein the skirt structure (37) has a first axial length and the tubular wall structure (49) has a second axial length with the first axial length being less than the second axial length. This arrangement provides a concentric intake and exhaust valve system with reduced reciprocating mass.

Abstract: The one-in-one valve allows more free flowing fluids, air or other gases, because of the one-in-one valve's size within a given circumference. The one-in-one valve is based upon a valve within a valve which can take more or less area within a given circumference as required. With the exhaust spring being of a different strength this enables the one-in-one valve to operate independently. The exhaust slots on the outer valve can be modified to a desired shape, length or width dependent upon the height of the exhaust port.

Abstract: The disclosed turbo-alternating engine exploits the gas generated in the cylinder of the alternating system in order to actuate a system of turbines ahead of the cylinders and at the extremity of the crankshaft in order to transmit the power thus generated to the crankshaft. Such reciprocal assistance of the turbo and alternating system makes possible the use of all the thermodynamic energy resulting from the combustion. As expressed before, the turbo-system does not consume fuel but it does take advantage to a maximum of the product of the combustion of the alternating system.

Abstract: An internal combustion engine, in particular a diesel internal combustion engine, has at least one cylinder chamber (3) with a piston (2). An annular inlet port (5) for the combustion air or the fuel/air mixture and an annular outlet port (6) for evacuating the exhaust gases, arranged concentrically with and inside the former, both open into the cylinder chamber (3). The inlet port (5) and outlet port (6) communicate with coaxial annular spaces (8, 10). The inlet port (5) and the outlet port (6), and the annular spaces (8, 10) with which they communicate, are separated from each other by a wall (23) attached to the housing. The inlet port (5) can be closed by an inlet valve (12) and the outlet port (6) by an outlet valve (13).
