Annular Cylinder - Barrel and Piston Clearance
2009-09-08 19:29:00 I am designing a special pneumatic annular cylinder with bore OD ~10.25 and bore ID ~8.25 with about 1" stroke. I was wondering if I could get some recommendation for clearances between piston and cylinder walls and perhaps tolerances for those diameters. I am using Standard AS568A Buna N o-rings. I

BMW May Use 4-Cylinder Engines to Meet U.S. Fuel-Economy Rules
2009-07-18 19:53:00 Bloomberg tells us that BMW 4-cylinders are coming to North America: http://www.bloomberg.com/apps/n-ews?pid=20601103&sid=ahNp0h-dZXILY The big question is what will happen to the brand image of BMW with a 4-cylinder product? BusinessWeek takes us thru that question: http://www.businessweek.com/mag-azine/content/08_42/b4104074245-498.htm You can see from the specs below that BMW has not yet produced a 4-cylinder engine which would be of interest to the North Americna market. 170 HP from 2 liters is not even close to leading the market, much less demonstrating BMW technology prosess. Several manufacturers including Ford and Nissan beat that number handily in their economy cars. The long-term answer is more technology, combined with turbocharging. The engine below is a direct-injected 4-cylinder gas engine from Europe. Click on it for a super high-res image (2319x2043 pixels, 300 pixels per inch). > Specs for the BMW 320i in Britain with an in-line 4...
