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 ...
“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 ...
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 ...
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 ...
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 ...

Why diesel engines need higher compression than gas engines
Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...
We may receive a commission on purchases made from links. While browsing auto repair and maintenance tools at your local parts store, you've likely come across compression testers like the Orion Motor ...
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 ...
Want to know how healthy or unhealthy your engine really is? Get yourself a compression tester and find out. Despite how complex many modern vehicles are, you can do many common repair and maintenance ...
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 ...
As a concept, the internal combustion engine is as old as dirt. To our luck, the ICE is still relevant nowadays thanks to engineering developments such as direct injection, cylinder deactivation, stop ...
Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...
