Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

Over the past few years, truck and engine makers have generated a lot of buzz around developing zero-emission drivetrains to help meet climate and sustainability goals. Traditional OEMs and tech start ...

Gasoline direct injection (DI) engines have been lurking in the shadows of gasoline-burning, internal combustion engine development for decades but are now becoming mainstream. This is all good, as DI ...

3D printing is a powerful tool for creating all kinds of stuff, but it has its limits. Hobbyist-focused machines that dispense melted plastic through a nozzle can only make parts that are so strong.

Researchers from Skoltech have published a paper in the journal Physica D: Nonlinear Phenomena presenting an analysis of steady propagating combustion waves—from slow flames to supersonic detonation ...

Car and truck makers see hydrogen internal combustion engines as a tool to attack carbon emissions and leverage much of the industry's existing technology, expertise and supply chain. But California's ...
