The phrase "air engine" is correct and usable in written English.
It can be used to refer to an engine that operates using air, such as in the context of air-powered vehicles or machinery.
Example: "The new prototype features an innovative air engine that significantly reduces emissions compared to traditional fuel engines."
Alternatives: "air-powered engine" or "compressed air engine".
The Competition The new Kia Picanto (almost mechanically-identical) is the obvious and cheaper rival with it's unrivalled seven year warranty but the Fiat 500 with the excellent Twin Air engine is more fun to drive and looks great if you are willing to spend a little more.
The air engine, in contrast, is made of aluminum and weighs in at a featherlight 80 pounds.
Micro CAES can use turbine components of the micro gas turbine, reciprocating expansion engine, or screw type air engine.
It is compatible with design and research needs of the modern closed-cycle regenerative air engine.
The torque output, airflow rate, and cylinder pressure were recorded; these values reflected the fluid characteristics of the compressed air engine during operation.
A conventional 100-cm3 four-stroke internal combustion engine was modified to a two-stroke compressed air engine and its output power and fluid properties at various intake pressures and rotational speeds were examined.
By the time he left office in 1974, Heath had nationalised or provided state support for air engines, the British motorcycle industry and Upper Clyde Shipbuilders.
This study investigated a modified intake and exhaust system for piston-type compressed air engines.
Air Engines (AE) are commonly designed to work in combination with internal combustion engines (ICE) due to low energy density.
There is no evidence that the performance of air engines yet owes much to detailed attention to regenerator design.
Hot air engines (Stirling and Ericsson engines) are well suited for micro-cogeneration applications because they are noiseless, and they require very low maintenance.
