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 ...
We might be covering ground that's well trampled for many, but the static compression ratio of an engine is simple to understand: it's all the volume of a cylinder above the compression ring at Bottom ...
In a conventional piston engine, the compression ratio defines the relationship between the largest and smallest volume of a cylinder - when its piston is at bottom dead centre and top dead centre ...

Why diesel engines need higher compression than gas engines
Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...
Ever since the first internal combustion engine hit top dead centre, engineers have been locked in an inexorable battle with compression ratios. Too low a compression ratio and the engine's 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 ...
Jonathan loves just about anything with a motor and a steering wheel. As a kid, Jonathan collected any kind of toy car he could lay his hands on, and begged his parents to take him to the monster ...

Why Red Bull Powertrains believe 2026 compression ratio intrigue is 'noise about nothing'
Red Bull Powertrains' Ben Hodgkinson is confident of having a fully legal engine in 2026, amidst speculation regarding ...
While the fashion in high-tech automotive developments might lean towards hybrids and electric vehicles at the moment, there’s still plenty of scope to improve the good old internal combustion engine ...
Infiniti has revealed an engine concept this year, and it is of the variable compression kind. While not the first of its type as a concept, this motor might bring a new line of internal combustion ...
