Formula 1 Engine calculations

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!

    Crap! That can be confusing

  2. The information which you have provided about calculation of average speed of racing car is very helpful.As I knew just the basic formula of average speed,doesn’t know about its real life application.

Let me hear from you!!! Drop a note!!
