A compressed-air vehicle (CAV) is a transport mechanism fueled by tanks of pressurized atmospheric gas and propelled by the release and expansion of the gas within a pneumatic motor. CAV's have found application in torpedoes, locomotives used in situations where standard locomotives are a hazard, and early prototype submarines.

A compressed-air car is a compressed-air vehicle powered by pressure vessels filled with compressed air. It is propelled by the release and expansion of the air within a motor adapted to compressed air.

壓縮空氣車（英語： compressed-air car ）是一種以壓縮空氣作為動力來源的 壓縮空氣交通工具 （ 英语 ： Compressed-air vehicle ） ，簡稱空氣車。 空氣車可以只透過空氣驅動，也能與 汽油 、 柴油 、 乙醇 等燃料混合驅動，也可搭配 再生制動 技術。

When the air car surpasses that speed, a motor will kick in to operate the in-car air compressor so it can compress more air on the fly and provide extra power to the engine. The air is also heated as it hits the engine, increasing its volume to allow the car to move faster [source: Cornell ].

2022年1月15日 · What makes the Compressed Air Car different is that it does not require any fuel. By compressing air into a tank, the stored air will release which can then move the pistons, driveshaft, and then the wheels. The main benefit of the compressed car is that it produced absolutely no pollution from its tailpipes.

2023年10月30日 · Pneumatic cars, or compressed air cars, are a revolutionary alternative to traditional gasoline or diesel vehicles. Instead of relying solely on fossil fuels, these innovative cars harness the power of compressed air in conjunction with a …

2021年1月1日 · Emission free compressed air powered energy system can be used as the main power source or as an auxiliary power unit in vehicular transportation with advantages of zero carbon emissions and improved the overall energy efficiency of the integrated energy system.

2010年12月1日 · In the face of the climate crisis, petroleum dependence, and volatile gasoline prices, it is imperative to explore possible opportunities in unconventional alternative-fuel vehicles. One such...

2024年5月23日 · What is a Compressed Air Car? The ultimate alternative fuel source in many people's minds would simply be the air we breathe. There would be little to no harmful emissions, a cheap and renewable fuel source, and a relatively simple fuel delivery system.

A compressed-air vehicle is powered by an air engine, using compressed air, which is stored in a tank. Instead of mixing fuel with air and burning it in the engine to drive pistons with hot expanding gases, compressed air vehicles (CAV) use the expansion of compressed air to drive their pistons.
