Does anyone know of a source, on the Internet preferably, for component inertial data for a real IC engine? In particular, what I'd like to obtain (for some real engine, any engine) are these items:
1. Piston weight (including wrist pin)
2. Cylinder bore dimension
3. Connecting rod length (center-to-center)
4. Connecting rod weight
5. Connecting rod center of mass location
6. Connecting rod mass moment of inertia
7. Crank pin diameter
8. Crank throw radius
9. Main bearing diameter
10. Engine type (2/4 stroke), make, and model
The major sticking point is item #6. I'm familiar with the approximation of the con rod as two point masses, but I'm trying to avoid that and use an actual measured value if possible.
If anyone has a source for this sort of data, it would be much appreciated. Thanks.
