The thermal efficiency of diesel engines has typically maxed out at around 46%, while gas engines only effectively use 30-36% of the energy available.

Toyota has now developed a new gasoline engine which it claims has a maximum thermal efficiency of 38 percent--greater than any other mass-produced combustion engine. The new units, 1.0 and 1.3 ...

Some Cyclone Engine Details Unlike IC (Internal combustion – regular gase engines) engines, the Cyclone engine uses an external combustion chamber to heat a separate working fluid, de-ionized water, ...

Right now, the only internal-combustion gas engine we're aware of that has over 50 percent thermal efficiency is the Mercedes-AMG 1.6-liter Formula 1 V-6. But that engine uses tech far too ...

Mazda's upcoming SKYACTIV-Z engine is poised to deliver unprecedented efficiency and thrilling power, proving that next-gen gas technology has a bright future.

SAE International Journal of Engines, Vol. 8, No. 4 (September 2015), pp. 1579-1586 (8 pages) ABSTRACT The goal of this research was to improve thermal efficiency under conditions of stoichiometric ...

A typical production engine has a thermal efficiency of around 40 per cent, meaning 40 per cent of the energy created when its fuel is burned is turned into motion. In 2017, the Mercedes-AMG ...

For comparison, a typical car engine runs at closer to 20% thermal efficiency according to Green Car Reports, meaning 80% of the energy released in combustion is lost as waste heat.

For comparison, Toyota's new 2.5-liter "Dynamic Force" engine allegedly has a thermal efficiency of 40 percent in gas vehicles and 41 percent in hybrids.

The SAE International Journal of Engines is a scholarly, peer-reviewed research journal dedicated to internal combustion engine science and engineering. The Journal spotlights innovative and archival ...

Nissan claims to have made a major efficiency breakthrough in efficiency for an internal-combustion in its e-Power hybrid system. The automaker announced Friday that it had reached 50% thermal ...
