"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 ...

The compression ratio isn’t just a number: it’s one of the greatest determining factors in engine building. Compression ratio determines the type of fuel, how much boost, and has a significant ...

Assuming a properly tuned engine, there are three factors that contribute to poor streetability: long cam duration, high compression ratios, and excessive cruise rpm. Since cam selection is largely ...

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 ...

The MCE-5 engine from MCE-5 Development in Lyon, France varies its compression ratio and uses a combined gear and rod-crank mechanism. The MCE-5 engine from MCE-5 Development in Lyon, France ...

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 ...

Now that Porsche is going deeper than ever into the world of turbocharged engines, the German automaker plans to rewrite the rules a little bit. The German engineers are currently on a quest for what ...

Mazda‘s upcoming SkyActiv-G engines will get a 14:1 compression ratio, the highest in the world for a gasoline engine, according to a report in Autoweek. Most cars run compression ratios of 8.5:1, ...
