Toyota's most efficient Corolla hybrid represents the hi-tech state of the industry. However, it still features technology ...

Researchers from the Southwest Research Institute (SwRI) have successfully developed an optimized spark-ignited hydrogen ...

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 ...

The rise to power of electrified powertrains had some believe, for a short while, that internal combustion engines (ICE) were done. To some extent, meaning the medium-term evolution of the automotive ...

MV Agusta revives a dual-crank engine design with a radical five-cylinder square concept, proving that internal combustion innovation is alive and well. The square engine layout uses dual crankshafts ...

A 2026 F1 internal combustion engine is a 1.6-litre V6 turbo capped at 400kW, or 536hp, revving to 15,000rpm and burning 100% sustainable fuel.

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 ...

This video initiates an exciting DIY engineering project focused on upgrading a small internal combustion engine with a ...

Effective management of the ratio between air and fuel in internal combustion engines underpins both performance optimisation and emissions reduction. The air–fuel ratio (AFR) determines combustion ...

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 ...

Internal combustion engines are literally the engines of the modern world. Without the invention of these genius mechanical creations, our world would be markedly different and the pace of life would ...

Rotary engines have an aura of cool. In games of Top Trumps, the V12 might have been king, but a rotary was a joker, a wild card. A lack of mainstream success no doubt contributes; there are reasons ...
