Last month we began a new series on the basic operation of the internal combustion engine. We realize that many of our readers may be new to the high-performance scene and do not fully understand the ...

High-output engines live in a world of brutal cylinder pressures, extreme temperatures and razor-thin safety margins, and the humble piston sits at the center of that storm. When power levels climb, ...

Pistons are an engine-building element we like to brag about, but you won't catch many of us boasting about having cast pistons. Cast pistons are for wimps. Many of us like to talk up hypereutectic ...

The team at Garage 54 replace aluminum pistons inside of an engine with custom-made plastic pistons. The engine, surprisingly, runs for longer than it has any right to run. Garage 54 specializes in ...

At the heart of an internal combustion engine lies a series of cylinders, cylindrical chambers that house the fiery combustion process. These cylinders, arranged in various configurations such as ...

The continuous drive for enhanced efficiency and reliability in modern diesel engines has prompted extensive research into the thermal management of critical components such as pistons. The ...
