Every car engine has quite a few details, ranging from cylinder count to compression ratios. How does changing the ...

Additive manufacturing has enabled targeted thermal expansion to boost effective compression beyond the limit set for the ...

Cylinder head milling has long been known as one of the shortest and easiest routes to increased performance. A few thousandths of an inch carefully machined from the surface of the head will increase ...

With the combustion chamber being the root of all horsepower, it only makes sense that you start spec'ing an engine build there. One of the key variables in engine building is compression ratio, or ...

“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 ...

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 ...

From June 1, the FIA will impose tougher tests on F1 power units in an attempt to clamp down on the compression ratio saga, but what tolerances will be permitted under the new tests?

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, ...
