Tech Spec: 100 Years of Changing Internal Combustion Technology
It would be interesting to hear what Nicolaus Otto, credited as the father of the first functional four-stroke IC engine, would say after seeing some of the advanced powerplants dropped into vehicles today. More
Tech Feature: The Variables of Valve Timing
Today's cylinder deactivation designs are used to reduce the fuel consumption and emissions of an internal combustion engine during light load operation. More
Tech Feature: Northstar Supernova
Introduced in 1993, GM's 4.6L 32-valve dual overhead cam all-aluminum V8 engine - housed in the Cadillac Allante, Eldorado and Seville STS - was considered a quantum leap forward for U.S. automakers.

That's becoming more and more of a challenge in recent years because good cores for popular domestic... More
Tech Tip: Piston Ring Installation in Smaller Bores
The event of engine downsizing has caused many changes in almost every engine component. Piston rings are no exception. They have been reduced in diameter as cylinder bores have become smaller, with corresponding width and wall reductions. Compression rings 1.5 mm wide (.0575") are becoming more common then rings which are 2.0 mm (.0775") or wider .... More
