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 ...

One of the easiest ways to test an engine's health is by checking its compression. Testing compression isn't something the average muscle car owner would do every year, but it is a useful tool to ...

You know what variable valve timing is. You're quite familiar with Honda's VTEC system. Now Infiniti has something new for you dive into, and it's all about changing an engine's compression ratio. The ...

You might talk about it often, but do you really know what compression is all about? Every engine has to make it and those that don't are hurtin' for sure. But, here's the confusing part, for this ...

While we like to think of 2002 as being part of a high-tech age, our beloved internal combustion engine hasn't really changed much in the last 50 years. We're still using pushrods and overhead valves, ...

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 ...

THIS PAPER PRESENTS a theoretical analysis of the ideal adiabatic Otto cycle engine. The analysis was made to examine the influence of compression ratio and dissociation on engine thermal efficiency ...

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 ...

The Porsche-Hilite technology is comparatively simple, and could be offered to every automaker if and when VCR comes to market. Share on Facebook (opens in a new window) Share on X (opens in a new ...
