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 ...

More power typically hurts fuel economy, but higher compression breaks the rule. Here's how modern engine design squeezes out ...

When comparing engine specs for nearly any combustion engine automobile, we see a number of variations available with differing outputs of horsepower and torque. We often have a choice of gasoline or ...

Almost all gasoline engines, whether they're efficient-yet-less-refined four-cylinders, high-horsepower V6s, or growly and torque-rich V8s, use much the same process to create power. The "Otto cycle" ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

Turbocharging a naturally aspirated engine raises big questions about compression, tuning, and heat. Here's what every project car owner should know.

Most engines generate power from an internal combustion system. On the basic level, these engines work by compressing fuel and air into a tight space. Within the cylinders of an engine, pistons pump ...
