For how basic it is, a car engine's four cycles of combustion are truly fascinating. A perfectly timed valvetrain ensures that the air/fuel mixture enters, compresses, and then exits without piston-to ...

There's no need to sugarcoat what bad piston rings can do to your engine. Those rather thin cast-iron or steel rings may look small and irrelevant to untrained eyes, but they play a vital part in ...

When I first started working for HOT ROD magazine more than 30 years ago, nearly all American domestic production cars used a thick, 5/64-5/64-3/16-inch piston-ring package. The top, usually ...

The folks at TRW have come up with a revolutionary idea for reducing the piston ring drag of the top compression ring. It is called the Pressure Balance Ring (PBR). Essentially, the PBR design amounts ...

Piston rings are used for sealing cylinders. They can work at higher temperatures than elastomeric, fabric, or polymer seals. Piston ring seals are very important for the efficient performance of ...

If asked what you wanted for piston rings in your engine build, would you know how to answer? Piston rings have the most important job in your engine. We will get arguments on this one because there ...

Piston ring grooves serve a larger purpose than simply supporting the rings. They impact combustion sealing, oil control, friction, and many more engine attributes. Wiseco is a world leader in piston ...

Solid elastomeric rings are compression seals that are used to prevent the leakage of fluid or air. They are made of flexible, elastomeric materials and are capable of repeated contraction and ...

Madison Square Garden Entertainment Co. construction crews used a Demag CC-8800 crane, the world’s fourth-largest crawler crane (according to Las Vegas Review-Journal), to lift a 170-ton steel ...
