The auto industry’s prioritization of electric vehicles is already coming at the expense of internal combustion engines, even at car companies previously resistant to the shift. Behind the scenes, the ...

Hydrogen combustion engines are inefficient, costly to maintain and worse for the environment than fuel cell or battery powertrains. But they're also noisy and fun, so automakers are starting to pitch ...

In a single-cylinder engine, the ability to homogenize and maintain the fuel-air blend prior to and during the burn is a classic combustion-engine problem. Add additional cylinders, and introduce ...

Ford once sketched a road where an engine's pistons never saw oil and engines ran hotter on purpose. In a late‑1980s patent application filed and granted in Europe, the company described an "uncooled ...

The automakers are making it official—they’re phasing out internal combustion and heading, with varying degrees of happiness, into an all-electric future. So at what point does the more than 120-year ...

The short answer is yes: innovative internal combustion engines, especially in combination with batteries, can and will play a crucial role in decarbonizing aviation for small aircraft, urban air ...
