SAE International Journal of Engines, Vol. 14, No. 3 (2021), pp. 335-344 (10 pages) The addition of a spark plug in place of the original fuel injector and fumigating natural gas (NG) inside the ...

What many consider the Holy Grail of combustion technology is one step closer to prime time. In the race to field energy-efficient vehicles, don’t count out internal combustion technology just yet. GM ...

A few years ago sparkless ignition or homogeneous charge compression ignition (HCCI) in gasoline engines was all the rage, with a number of major automakers including General Motors, Daimler and ...

Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...

All combustion type engines require two variables to make power-air and fuel (gas, alcohol, methanol, etc). More air and fuel in the combustion chamber means more power potential. However, in reality ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

Car manufacturers are delving deep into their boxes of tricks to make internal combustion engines more efficient. Infiniti unveiled a variable compression ratio engine last year, and hybrid technology ...

We're always looking for ways to make more power without spending too much money. We bolt on carburetors and intake manifolds. We also perform cam swaps in our quest for power. When that doesn't meet ...

Mazda has detailed the next-generation of its SkyActiv engine family, which will feature innovative compression ignition technology. While the new SkyActiv engine is still under development, Mazda ...
