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.
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 ...
Apart from the very curious, not many people ask why diesel engines, compared to gasoline, run higher compression ratios. The argument is reasonably straightforward and starts with fuel characteristics – diesel is less volatile than gasoline, heavier ...
The MCE-5 engine from MCE-5 Development in Lyon, France (www.mce-5.com), varies its compression ratio and uses a combined gear and rod-crank mechanism. Varying compression from 7:1 to 20:1 makes the engine more efficient than current gas engines.
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 ...
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 ...
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 ...
Nissan's Infiniti division will present its first Variable Compression-Turbocharged (VC-T) engine at the Paris Motor Show next month. This technology took them more than two decades to perfect, and the result is a high performance engine offering that ...
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 ...
