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 ...

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 ...

Here you can see basic piston terminology, including major and minor thrust locations. Of particular note is the fact that piston pin offset can be used to counteract combustion pressures on the ...

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 ...

Common "Old Wives' Tales" and the rigid "60/80 rule" for piston aircraft engine compression checks are often incorrect and can lead to unnecessary cylinder removals, as low readings don't ...

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 ...
