Disclosed in the present invention are a gas-driven engine intake gas distribution device and an engine constructed therefrom. The structure of the gas-driven engine intake gas distribution device is as follows : an intake pipe (7) is communicated with a gas distribution chamber (8) through a gas inlet control valve (5), the gas distribution chamber (8) is communicated with an engine cylinder (27) through a gas outlet control valve (10); the gas inlet control valve (5) and the gas outlet control valve (10) are driven by a valve drive mechanism; the gas distribution chamber (8) can be provided with one or more of the three devices comprising a fuel nozzle (9), a spark plug (6) and a gas distribution chamber volume regulation piston (11). The gas-driven engine constructed from the intake gas distribution device with the gas distribution chamber volume regulation piston (11) can enable an adjustable expansion ratio. An internal combustion engine constructed from the intake gas distribution device can improve fuel thermal efficiency and can enable an adjustable expansion ratio; the one with the gas distribution chamber volume regulation piston can also enable an adjustable expansion ratio; an engine constructed from the internal combustion engine with the adjustable expansion ratio and a turbocharger device can further improve fuel efficiency, and the exhaust emission is better in environmental protection. |
