Schematic of the proposed pneumatic propulsion with multi-option for connectivity, be it grid and/or renewable energy connectivity. Scientists say they have created a methodology that could replace ...

Motorcycle engines live and die by how well they shed heat, and the choice between liquid and air cooling shapes everything from performance to maintenance. Riders weighing a new purchase or planning ...

In its purest form, an engine is nothing more than an air pump; it takes in air and then returns it, although in a slightly modified form. Maximizing an engine's ability to process air will also ...

There's an old saying in engine tuning that when adjusting the mixture of your engine you can be too rich a bunch of times, but only too lean once. With that in mind, determining the air-fuel ratio ...

Researchers say they've developed a method that could replace the two diesel engines currently powering a ferry boat with pneumatic propellers - offering a potentially cleaner, quieter, and more ...

Diesel engines typically have beefier, more robust cooling components to keep the motor cool in varying conditions. Modern diesels operate at a higher compression ratio, which makes their combustion ...
