Multicylinder catalytic engine
A multicylinder catalyst engine is described comprising, a first cylinder and a first piston reciprocating therein, a second cylinder and a second piston reciprocating therein, the first cylinder including an intake port, an intake valve in the intake port admitting all of the air and fuel for the engine, air/fuel mixing means connected to the intake port, the intake valve being opened as the first piston draws an air/fuel mixture into the first cylinder, and the intake valve being closed as the first piston moves to compress the mixture, a transfer passageway in communication between the first and second cylinders, a transfer valve in the passageway adjacent the first cylinder closing while the air/fuel mixture is drawn into the first cylinder and opening when the mixture in the first cylinder is compressed for transferring the compressed mixture from the first cylinder toward the second cylinder, a catalyst positioned in the passageway downstream of the transfer valve for igniting the compressed mixture when the transfer valve is closed thereby powering the second piston, an exhaust port connected to the second cylinder, and an exhaust valve positioned in the exhaust port for exhausting gas from the second cylinder.
