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 influence on an engine's power and torque potential ...

The FIA will reportedly hold a second early-week meeting with technical experts, with the engine compression ratio debate set to be put on the table ahead of PUAC. According to The Race, the meeting is scheduled for Monday — following an initial one held on January 22 that was less about the current interpretation and more about might need to be amended for the future — with the focus now shifting to establishing a clear methodology for

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 design. It looks like Nissan is the Indiana Jones of ...

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 things that make up the total volume above the piston at ...

As always, let’s take a look at the two main headlines from today, Sunday 1 February, in Formula 1. The FIA and engine manufacturers are set for a decisive week of talks, with two separate meetings lined up to address the long-running debate over the engine compression ratio.

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 high-powered 8:1 and a hugely efficient 14:1 ratio as ...

One of the key variables for an internal combustion engine is its compression ratio. This is the ratio of the maximum volume within the cylinder (when the piston is at bottom dead center) and the minimum volume within the cylinder (when the piston is at ...
