Low- And High-Compression Fuel Economy Engines: The Techniques Are About The Same, But The Approach To Each Is Somewhat Different. A.Most stock cylinder heads have factory-cut undercuts of the type ...

The crux of the matter lies in that the Formula 1 compression ratio is not measured by sensors during engine operation, but statically. The FIA simply compares the ratio in volume in the cylinder ...

As we face the end of the internal-combustion era, the straight-six has made an unlikely comeback. Well, unlikely might not be the right word for an engine configuration of such fundamental rightness.

Engine compression ratios have become a hot topic ...

Increasing an engine’s compression ratio is a proven way of unlocking extra horsepower, but there’s a point of diminishing returns. The team at Garage 54, the Russian mechanics who built a V16 using ...

A.Here you can see locations of sharp-edged material left from factory machining operations. Material removal should be kept to a minimum, since we are dealing with low engine rpm for which enlarged ...
