Read on as we list ways to figure and measure your compression ratio, total piston volume, and choosing the best pistons. Read on for more details along with photos only in Mopar Muscle Magazine ...

Before you can determine an engine's compression ratio, several factors must first be nailed down. These include piston volume, deck clearance, gasket thickness, and combustion chamber volume.

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 ...

“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 ...

Around 2001, Saab Automobile introduced a bold new engine concept that used a hinged, two-part engine block to vary the compression ratio automatically.

Too low a compression ratio and the engine's efficiency and performance would suffer, too high a compression ratio and catastrophic self-disassembly could occur.

Every engine has a specific compression ratio. The air-fuel mixture is compressed in the cylinder to create an ignition, the force of which depends on the compression ratio: the volume of the ...

Static compression is what engineers, engine builders, and even do-it-yourselfers dial in to an engine build. Basically, it's the exact compression ratio formulated into engine construction in a ...

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 ...

Infiniti's taught the internal combustion engine a new trick to raise its versatility a bit -- variable compression ratios.

It is the first variable compression engine to reach full production. The company spent 20 years developing the variable-compression-ratio technology and filed more than 300 patents on the design.

The next-generation Infiniti QX50 crossover will be powered by a turbocharged four-cylinder engine introducing a technology never seen before in a regular production vehicle: variable compression.
