摘要： Embodiments of a compact pressure swing reformer are disclosed. Certain embodiments have a construction comprising multiple rotating reformer beds, high temperature rotary valves at the bed ends, and E-seals to seal the beds to the valves. Several possible designs for introducing reactants into the beds also are disclosed. The multiple reformer beds are configured to provide for pressure equalization and ‘steam push’. The compact pressure swing reformer is suitable for use in fuel cell vehicle applications.

摘要： A W6 engine has two W3 engine units disposed juxtaposed on a common crankshaft. Exhaust pipes of the cylinders containing the pistons driving the common crankshaft are guided to an exhaust. Each cylinder has at least one intake valve and at least one exhaust valve. The intake valves for the individual cylinders are disposed in wall portions of the respective cylinders oriented in the same circumferential direction about the crankshaft or lateral portions of their cylinder head. The exhaust valves for the individual cylinders are disposed in opposite circumferential direction. Each exhaust valve closes an exhaust pipe, which is led from the valve seat of the exhaust valve to the outer surface of the W3 engine unit in which the cylinder with the exhaust valve is disposed.

摘要： An internal combustion engine has cylinder wall cavities located near the top dead center stroke end to allow optimizing the compression ratio in first stage compression, as function of fuel octane number used. The volume of the cylinder wall cavities is designed to be adjustable, even when the engine is operating. Using a conventional piston motion, the second stage compression becomes accelerated as soon the upper piston ring seals-off the cylinder wall cavities. This is due to the sudden significant reduction in volume. During the power stroke, after the upper piston ring opens the cylinder wall cavities; their fuel content is ignited by second stage combustion products. Because the torque required during accelerated compression is no greater than during first stage compression, stresses in the crankshaft are no more than in conventional spark ignition engines. This allows small displacement engines to be of light weight and to be hand cranked.
