ABSTRACT:
A pump-motor is used to move engine pistons to a position where the exhaust ports of a first cylinder are opened, and later to move the pistons to a position where the inlet ports and exhaust ports of the first cylinder are closed. Fuel is then injected into the first cylinder, and a starting motor is used to compress an air-fuel mixture in the first cylinder sufficiently to produce combustion of that mixture. A drive connection between a starting fluid-motor and the pistons is released. Fuel is injected into the second cylinder. The fuel-air mixture in the second cylinder is compressed sufficiently to produce combustion of that mixture.
