Abstract
An engine has a crankshaft. A power piston is slidably received within a first cylinder and operatively connected to the crankshaft such that the power piston reciprocates through a power stroke and an exhaust stroke. A compression piston is slidably received within a second cylinder and operatively connected to the crankshaft such that the compression piston reciprocates through an intake stroke and a compression stroke. A gas passage interconnects the first and second cylinders. The gas passage includes an inlet valve and an outlet valve defining a pressure chamber therebetween. Combustion is initiated in the first cylinder between 5 degrees and 40 degrees of rotation of the crankshaft after the power piston has reached its top dead center position.
