The first hot topic of the new Formula 1 rules era has sparked up debate over compression ratios, with teams treading a fine ...

The biggest controversy of the winter break, at least for now, has been settled. A solution developed by Mercedes to increase ...

A gasoline piston engine that can dynamically change its compression ratio —that is, the amount by which the piston squeezes the fuel-air mixture in the cylinder—has long been a holy grail of engine ...

Roadkill's David Freiburger, Roadkill Garage's Steve Dulcich, and Westech Performance's Steve Brul build and test every type of engine and configuration imaginable on Engine Masters.Subscribe to the ...

Teams are continuing to press for clarification from the governing body over a response to rumours that two engine ...

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 ...

Forget variable length intakes and variable valve timing, Infiniti is going all the way and introducing variable cylinder compression ratios. The new VC-T turbo engine automatically adjusts between a ...

Previous studies have shown that increase compression ratio (CR) is an effective way to improve thermal efficiency of gasoline engine without changing the mechanical structure and working cycle, ...

As a concept, the internal combustion engine is as old as dirt. To our luck, the ICE is still relevant nowadays thanks to engineering developments such as direct injection, cylinder deactivation, stop ...

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 ...
