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 ...

With every passing day the Mule provides opportunities beyond our original expectations. Since the 467ci engine belongs to HPP editor Tom DeMauro, it is at our beck and call. This affords HPP the ...

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 computer generated power stroke of an internal combustion engine, following ignition - Pathompong Thongsan/Getty Images When comparing engine specs for nearly any combustion engine automobile, we ...

We all know the age-old maxim, "There's no replacement for displacement." It's the truth. That's why so many sanctioning bodies use displacement and compression rules to limit engine power. Of course, ...

Let’s clarify the numbers: the current Formula 1 regulations allow an internal combustion engine compression ratio of 16:1 measured at ambient temperature. All power units checked in Australia were ...

On paper, Nissan's variable-compression turbocharged engine should have been pretty awesome. Since it could change its compression ratio on the fly, it promised the power of a bigger engine when you ...

Modern compression ignition engines convert fuel energy into mechanical work by auto-igniting a compressed air–fuel mixture. Accurate modelling of in-cylinder processes is vital for both performance ...
