Automakers like Toyota, Mercedes, and Mazda are ditching V6 engines in favor of more efficient and cost-effective powertrains.

Engineers have a lot to think about when designing new engines, and one of the biggest considerations is the shape of the pistons in the cylinders.

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

Pratt & Whitney thinks the aerospace industry might need a bit more time to achieve a broad goal of squeezing at least 20% more efficiency out of the next generation of narrowbody aircraft engines.

As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, higher-compression engines tend to make more power while offering better fuel ...
