Abstract: An engine assembly includes an engine block defining a first cylinder bore, a second cylinder bore directly adjacent to the first cylinder bore and a third cylinder bore directly adjacent to the second cylinder bore. The engine block defines a first distance from a diametrical center of the first cylinder bore to a diametrical center of the second cylinder bore and defines a second distance from the diametrical center of the second cylinder bore to a diametrical center of the third cylinder bore. The first distance is different than the second distance.

Abstract: The horizontally opposed center fired engine improves on the traditional design of the horizontally opposed engines and center fired engines with a better engine geometry. The present invention utilizes four pairs of opposing pistons to compress a larger volume of air-fuel mixture within four different cylinders. The four different cylinders are radially positioned around a center axle in order to achieve a perfectly symmetric engine geometry. The center axle consists of two different shafts spinning in two different directions, which could drastically reduce engine vibrations in the present invention. Engine vibrations are caused by a change in engine speed and result in a loss of energy. Due to the design, the present invention will only experience energy loss in the form of entropy and friction. Thus, the present invention can convert a higher percentage of chemical energy into mechanical energy than any other internal combustion engine.

Abstract: An internal combustion engine having a cylinder crankcase and a v-shaped cylinder configuration and having a lubricant circuit which operates according to the dry sump principle and has a lubricant reservoir, wherein the lubricant reservoir is located within the cylinder crankcase in the space between the cylinders.

Abstract: An efficient novel motor is described which works with hydrogen. The motor has 2 compressible chambers for better control of fuel and oxidant ratios. A turbogenerator is utilized to ventilate interior and exterior parts as well as generate electricity to transform waste water into fuel.

Abstract: An odd-cylinder V-type internal combustion engine including 2n+1 cylinders (n is a natural number) arranged in two banks and pistons fitted in the cylinders has a crankshaft provided with n common crankpins (KC) each connected to the two paired pistons respectively belonging to the two banks, and one odd crankpin (KS) connected to the one unpaired piston. The common crankpins (KC) are disposed at the same phase. Bank angle &thgr; between the two banks meets &thgr;=cos−1(½n). The odd crankpin (KS) is disposed (180−&thgr;)° behind the common crank pins (KC) with respect to the rotating direction of the crankshaft when the unpaired piston belongs to the front bank with respect to the rotating direction of the crankshaft.

Abstract: This invention relates to an internal combustion engine for a motorcycle, with two or more single cylinders arranged in a plane approximately normal to a crankshaft, each cylinder accommodating a reciprocating piston and the pistons acting via connecting rods on the same crank of the crankshaft supported in a crankcase. To reduce manufacturing expense, the engine is to be provided with modular components for universal use with at least two different cylinder arrangements (V-type, W-type).
