摘要： An internal combustion engine is described that includes an expansion cylinder adjacent to a first combustion cylinder (or power cylinder). Combustion gases from the first cylinder are directed to the expansion cylinder to act on the piston in the expansion cylinder. The expansion cylinder has a larger bore (i.e. larger diameter piston) and/or a longer stroke than the first cylinder. The longer stroke also results in a much larger crankshaft arm resulting in a significantly improved mechanical advantage (i.e. torque). In addition, the expansion cylinder includes a check valve that is designed to automatically open the expansion chamber to atmosphere if a negative pressure develops due to the varying amount of exhaust gases at different speeds. In one embodiment, two power cylinders can be connected to one expansion cylinder.
