Abstract: A reciprocating compressor. A hollow cylinder tube contains a piston assembly having two pistons connected by a piston rod. At each end of the cylinder tube is an outer chamber between an end plate and an outer end of the proximate piston. These two outer chambers and the outer ends of the pistons define a power cylinder at each end of the cylinder tube. In the mid-portion of the cylinder tube, a center divider is situated between the pistons and has an aperture that allows the piston rod to reciprocate through it. The two inner chambers formed thereby and the inner ends of the pistons define two compression cylinders in the mid-portion of the cylinder tube. The two compression chambers share a suction manifold and a discharge manifold, but have independently operating suction and discharge valves.

Abstract: A split-cycle engine with disc valve includes a crankshaft, a power cylinder and a compression cylinder. A gas crossover passage interconnects the compression cylinder and the power cylinder. An air intake port circumscribes a periphery of the compression cylinder and defines an outer valve seat. An annular ring having a generally central opening is disposed between the compression cylinder and the air intake port and forms a washer valve for opening and closing the air intake port. A disc valve member is concentrically mounted over the central opening of the annular ring. The disc valve member includes a piston portion having a sidewall biased into engagement with the outer valve seat for controlling flow between the compression cylinder and the gas crossover passage.

Abstract: A method for decelerating an expansion piston of an engine is presented. The engine includes an expansion piston slidably received within an expansion cylinder and operatively connected to a crankshaft such that the expansion piston reciprocates through an expansion stroke and an exhaust stroke of a four stroke cycle during a single rotation of the crankshaft. A compression piston is slidably received within a compression cylinder and operatively connected to the crankshaft such that the compression piston reciprocates through an intake stroke and a compression stroke of the same four stroke cycle during the same rotation of the crankshaft. The method includes accelerating the expansion piston during the expansion stroke from the expansion piston's top dead center position, and decelerating the expansion piston during at least a portion of the expansion stroke crank angle interval between 0 degrees and 60 degrees after top dead center.

Abstract: A diesel internal combustion engine in which during the starting and partial load operation, a number of the cylinders are operated as compressor cylinders and a number as engine cylinders. The supplied charging air of one compressor cylinder (26) is used as actuating medium for the valves (35 to 42) which are to be controlled corresponding to the operating condition of the internal combustion engine, in the connecting lines (27 to 34) between the compressor cylinders (19 to 26) and the engine cylinders (11 to 18) in the absence of a compressed air network. As a result thereof, auxiliary energy of the internal combustion engine (10) is needed only for the initiating control and a rapid shifting of the operating conditions is attained with minimum expenditures.

Abstract: A two-stroke engine possesses a cylinder, in the cylinder bore of which a combustion chamber is formed. The combustion chamber is bounded by a reciprocating piston, which drives a crankshaft rotatably mounted in a crankcase. A crankcase interior is fluidically connected to the combustion chamber across at least one transfer channel in at least one position of the piston. The at least one transfer channel emerges with a discharge opening in the crankcase interior and with at least one transfer window on the cylinder bore. It is proposed that all transfer channels have an average length as measured from the discharge opening to the transfer window, the average length being at least 1.5 in relation to the stroke, and that the volume of the crankcase interior including all transfer channels is at most 3.1 in relation to the piston displacement.
