You might have heard about high compression ratios, but what exactly are they, and what kind of effect do they have on an ...

"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 ...

Rod ratio is simple to calculate: Take the length of the piston rod and divide by the length of the crankshaft stroke. Why or how would that make a difference in building an engine? Piston rod length ...

The effects of compression ratio on brake thermal efficiency at full load as well as part load operating conditions typical of those encountered in the CAFE test procedure are important considerations ...

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 ...

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 ...
