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 ...

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 ...

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 ...

Ignition coils last far longer than spark plugs and only need replacement when symptoms appear. Here’s how to tell if coils ...

Mazda’s new range of Skyactiv-X engines under development are set to replace the current Skyactiv-G range in 2019. They use compression ignition technology that has previously only been used in diesel ...

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 ...

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

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 ...
