  • One cycle internal combustion engine
    Patent number: 6796127
    Abstract: A one cycle internal combustion engine (10) configured for powering a vehicle (V) is disclosed. The engine (10) broadly includes an engine block (12) defining three cylinders (14, 16, and 18), three double-acting pistons (20,22, and 24) slidably received in the corresponding cylinders (14,16,18), respectively, a fuel delivery system (26) for delivering fuel to the cylinders (14,16,18) to drive the pistons (20,22,24), a steam delivery system (28) for delivering steam to the cylinders (14,16,18) to additionally drive the pistons (20,22,24), a crankshaft (30) rotatably supported by the block (12) and drivingly rotated by the pistons (20,22,24), and a temperature regulation assembly (32) for regulating the temperature within the engine (10). The double-acting pistons (20,22,24) are powered on every stroke. The fuel delivery system (26) delivers diesel fuel to the cylinders (14,16,18) for combustion therein to drive the pistons (20,22,24).
