I wanted to share something I did related to piston speeds. As you know Formula 1 is near the pinnacle of technology in engine development. Back in 2003, I read an article about how the BMW Racing team developed their engine. The article stated they were very proud that for the 2003 season, their engine was a 3 liter V10 design which had a maximum racing RPM of 19200 and the piston sustained a maximum piston speed of 40 meters per second (which equals 7872 feet per minute maximum). The article further stated their piston sustained a maximum acceleration of 10,000 times the force of gravity at maximum revolutions per minute.
I was always curious about the bore vs stroke for such a small displacement, high revving engine, but they always kept that secret. I grabbed my old Dynamics book and realized I could solve for bore and stroke by two methods, using angular velocity and again by piston acceleration.
Please note, I found a typo on Page 1. It says VA and VB are parallel, when clearly it should be written VB and VC are parallel.
Enjoy and discuss!
