An intake gas distribution device for a gas-driven engine and an engine using same, the intake gas distribution device of the gas-driven engine comprises: an intake duct (7) is in communication with a gas distribution chamber (8) via a intake control valve (5), and the gas distribution chamber (8) is in communication with an engine cylinder (27) via a exhaust control valve (10); the intake control valve (5) and the exhaust control valve (10) are driven by a valve actuating mechanism; the intake gas distribution device is provided with one or more devices selected from the following three devices: a fuel nozzle (9), a spark plug (6) or a gas distribution chamber volume adjusting piston (11), and the fuel nozzle (9), the spark plug (6) and the gas distribution chamber volume adjusting piston (11) are all disposed on the gas distribution chamber (8). The gas-driven engine with a gas distribution chamber volume adjusting piston (11) using the intake gas distribution device can achieve adjustable expansion ratio, the internal combustion engine using the intake gas distribution device can improve fuel thermal efficiency and can achieve adjustable compression ratio; and the internal combustion engine with a gas distribution chamber volume adjusting piston can also achieve adjustable expansion ratio. |
