Every car engine has quite a few details, ranging from cylinder count to compression ratios. How does changing the ...

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 ...

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 ...

At first glance, the concept of engine compression is simple enough:It's the ratio of the volume of the combustion chamber and bore when thepiston is at bottom dead center (BDC) versus when it is at ...

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 ...

Nissan’s variable-compression turbo (VC-Turbo) is a unique engine capable of variable compression adjustment. Unlike traditional engines, which have a fixed compression ratio, the VC-Turbo engine ...

Didn't expect you'd be looking up articles online about engine compression a few months ago, did you? That's what new F1 regulations can do to you. Luckily, we're here to help. Before we dive into the ...

You might have heard about high compression ratios, but what exactly are they, and what kind of effect do they have on an engine's fuel efficiency?

“Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...

Compression: An automotive term used by everybody, forever. Let's get into some detail and maybe develop a better understanding. Pressure, and more pressure: It's a must-have to produce power within ...

Formula 1's governing body, the FIA, has announced a resolution to the sport's regulatory row over engine compression ratios, with a tweak to the regulations set for June 1 and a further change in ...

While significant attention is being paid to battery-electric and hydrogen fuel-cell powertrains, carmakers are still trying to wring more efficiency out of internal-combustion engines. Now, Infiniti ...
