The newly formed organization will host a series of meetings of its members to exchange research results, insights and ideas regarding opposed-piston engines with hydrogen combustion. Several ...

When the pistons reach their respective bottoms, fresh air flows in from ports at the bottom, while exhaust is rejected through ports at the top. That fresh air is squeezed into a small pocket in the ...

Gasoline and diesel engines feature many differences aside from fuel type. Compared to gasoline engines, a diesel is typically a lower-revving, torquier design, hence why it's often preferred over ...

Some of the world’s most complicated engines were created to achieve a specific objective. These engines were built to satisfy monster power requirements or to hit a high level of performance within ...

The rotary engine is unique in its success and failure and its ability to make an impact with a completely different way of thinking. As it is, every production car for the last 130 years, aside from ...

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 ...

You've heard that pistons have rings, but have you ever wondered why there are three? Here's how piston rings work together ...

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 ...

Heat is a byproduct of combustion. Both air-cooled and water-cooled engines need to dissipate that heat to keep the engine from running too hot. Can piston rings play a role in managing that heat?
