<p>A compressed gas engine (18) and a motor vehicle using the same are provided. The compressed gas engine (18) includes a shell, an impeller (74) and a main power output shaft (120). The impeller (74) is fixed on the main power output shaft (120) and arranged within the shell. An injection inlet (620) is disposed on the shell to inject gas into the impeller (74) within the shell. Pluralities of working chambers (69) are formed on the impeller's circumference jointing to the inner surface of the shell. The working chambers (69) are enclosed by the inner surface of the shell, so that the gas injected from the injecting inlet (620) into the working chambers (69) can not only rotate the impeller (74), but also stay in the working chambers (69) temporarily. Also, a gas jet outlet (640) is so disposed on the shell that when going to the gas jet outlet (640), the compressed air staying in the working chambers (69) temporarily can expand and jet outwards to do work and then rotate the impeller (74) in turn. Therefore, the gas can do work when entering into the compressed gas engine (18) as well as being exhausted therefrom.</p> |
