Steady state experiments on a single cylinder spark ignition engine were performed to investigate the effects of compression ratio on nitric oxide and hydrocarbon emissions using natural gas as the ...

SAE International Journal of Engines, Vol. 11, No. 6 (2018), pp. 643-656 (14 pages) In this work, various techniques are numerically investigated to assess and quantify their relative effectiveness in ...

Red Bull Powertrains' Ben Hodgkinson is confident of having a fully legal engine in 2026, amidst speculation regarding ...

Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why that is and what it means.

Increasing an engine’s compression ratio is a proven way of unlocking extra horsepower, but there’s a point of diminishing returns. The team at Garage 54, the Russian mechanics who built a V16 using ...

There’s still another couple of months before the 2026 crop of F1 cars takes to the track for the first preseason test. It’s a year of big change for the sport, which is adopting new power unit rules ...

"Making horsepower is all about building adequate cylinder pressure," proclaimed Mike Dezotell of Dez Racing, as we embarked on our latest adventure into the world of compression ratios for boosted ...

Strictly defined, compression ratio is the total volume above the piston at bottom dead center (BDC), divided by the total volume above the piston at top dead center (TDC). First, let's look at the ...
