NPR (Nippon Piston Ring) Piston Rings.

2019-1-24 · Steel piston rings allow for a reduction in the radial wall thickness. This (thinner) and lighter design seals more completely against the ring groove. Also, NPR''s steel ring designs with greater material strength, reduced width and radial wall dimensions conform better to less than perfect cylinder bores. These two advantages can

Piston Ring and Groove Side Wear Analysis for ...

2015-11-1 · Piston ring wear is a major factor determining a diesel engine''s life. A ring is subjected to wear between its front face and the cylinder wall as well as at the interfaces between the ring and groove top and bottom flanks. In many modern engines, ring and groove wear are becoming more of a limiting factor for ring durability than face wear.

High Performance Piston Rings and Cylinder Finishes ...

2006-1-1 · Today''s performance ring sets are thinner, lighter and more conformable than ever before. Thinner, low-tension rings reduce friction for more usable horsepower. Less weight reduces ring groove pound out. Narrower rings also allow tighter tolerances and less blowby. All very good things when you''re building a performance engine. But they also require rounder, straighter cylinder […]

Installing Piston Rings.

 · Take a piston with no rings on it, turn it upside down in the bore and use it to square the ring in the bore. Push the piston down just enough so that the ring is positioned at the top of its normal travel. This is especially important if you''re working with a block that hasn''t been freshly bored and may have a little taper in the cylinders.

Ring Groove

Ring fluttering can sometimes take place during increased revolution speeds and this increases blow-by. This is due to ''floating'' of the ring. Floating occurs when an inertial force lifts the ring in the piston ring groove, which in turn spoils the airtight seal between the lower face of the ring and the ring groove.
