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

In a conventional application, there are three rings per piston. The top ring is called the compression ring. Its purpose is to seal the combustion gas pressure, transfer heat from the piston to the ...

In an effort to increase the basic understanding of automobile technology for those new to the hot rod world or those who have been involved for a while but don't have a good foundation of knowledge.

When we turn the key, what happens under the hood and why? How does an automobile engine work? What is that sound we hear and the propulsion we feel when the accelerator is depressed? "External ...

Piston rings are the seals in your cylinders, giving you better compression and power, but what happens if they wear or break? And how can you spot the signs?

The earliest piston engines typically had only one cylinder, and at best, produced horsepower measured in single digits. But once you have a working engine, it’s a relatively short step to adding ...

Free-piston engine generators and linear machines represent an innovative departure from conventional rotary systems, offering high thermal efficiency and operational flexibility by eliminating the ...
