Internal combustion engines typically have low efficiency, with modern gasoline engines around 35% and diesel engines ...

The automotive world spent more than two decades chasing a white whale: a gasoline engine that ignites its fuel the way a diesel does — through compression alone, without a spark. Mazda claimed it had ...

Combustion efficiency in internal combustion engines refers to the proportion of chemical energy in the fuel that is converted into useful mechanical work. Attaining high combustion efficiency is ...

LAS VEGAS--(BUSINESS WIRE)--Achates Power, Inc. (API) showcased at ACT Expo what has been demonstrated as the cleanest and most efficient internal combustion engine (ICE) architecture to date.

Researchers have theoretically linked ignition and deflagration in a combustion system, unlocking new configurations for stable, efficient combustion engines due to the possible existence of any ...

BEIJING (Reuters) - Nissan Motor Co, an early mover in the electric vehicle market, will use the Los Angeles auto show next week to send a message about gasoline-fueled engines: They're not dead yet.

In case you missed it, the automotive industry has been on a steady trajectory of internal combustion engine (ICE) downsizing for years. Battery-powered electric vehicles may capture most of the ...

A better mousetrap? Even now, as electrification seems poised to end the internal combustion engine’s long run as the transportation motivator of choice, enterprising tinkerers continue to propose ...

The benefit: a theoretical efficiency boost up to 25% over regular combustion engines. One drawback: they work much less efficiently at atmospheric pressures, so they're much happier at supersonic or ...

Combustion efficiency and emission control in internal combustion engines lie at the heart of efforts to reconcile performance, fuel economy and environmental impact. Optimising the conversion of ...
