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 ...

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

"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 ...

The compression ratio isn't just a number: it's one of the greatest determining factors in engine building. Compression ratio determines the type of fuel, how much boost, and has a significant ...

Today's low-octane unleaded gas mandates a compression ratio reduction for '60s supercars. The easiest way to lower compression is usually to swap on late-model heads; not only do their larger ...

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 ...
