Combustion engines, the engines in gas-powered cars, only use a quarter of the fuel's potential energy while the rest is lost as heat through exhaust. Now, a study demonstrates how to convert exhaust ...

Something unexpected is happening on American roads right now. People who once proudly drove electric vehicles are quietly returning to gas stations. S. EV owners want to switch back to ICE vehicles ...

Forbes contributors publish independent expert analyses and insights. I am a professor at Cal State LA and the technical director for the Hydrogen Research and Fueling Facility. We go for better ...

Any certified gearhead knows that diesel engines do not use spark plugs. But why not? If power in an engine is created by combustion or explosion of flammable liquids, won't a spark plug in a diesel ...

Scientists are exploring a surprisingly simple way to clean up diesel engines: adding tiny droplets of water to the fuel. During combustion, the water rapidly vaporizes, triggering micro-explosions ...

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 ...

When comparing engine specs for nearly any combustion engine automobile, we see a number of variations available with differing outputs of horsepower and torque. We often have a choice of gasoline or ...

We're not going to get into the whole "who made the first car" argument today. But there's not much doubt that the overall history of self-propelled vehicles goes back well beyond the Mercedes Patent ...
