Calculating overall Car life

Oke the distance per revolution of the engine. It is really complicated to calculate the real mileage.

But what does rev mean? The mileage of the engine, distance in no load?

When you design an engine, the engine designer calculates the engine lifetime in Million Revolutions (MRev) of the crankshaft. I don't know the algorithm behind it, but it depends on many things (materials used, flywheel weight, air intake, cam profiles, max. revs etc.).

What I've created is a very simple way to get a rough estimation, which mileage your drivetrain (engine, gearbox, differential) can reach.

Maybe the character of of the countryside should be considered, too. Mountains (e.g. Switzerland, Austria) and dust (Africa?) will definitley shorten the livetime of several parts.
For Example, we could develop a table with values that reduce lifetime for every country (or region)
Flat, dry but dustfree (only as reference) would be 0
Mountains, wet (with salt in the wintermonths), dustfree could be 0.8
Flat, dry, dusty cpuld be 0.9
and so on.
These values are completely random, but I think it shows what I'm trying to do.

Oke that's complicated. But thanks for your information, Zephyroth!

Good thoughts everyone, keep at it and we'll be refering back to this thread when we do more design work on car life

Ah, something about my table:
it would be better if we took 1 for the reference
then all other values <1 and we got a value that could be multiplied with the carlifetime.
Rough example:

overallcarlife = Zeph's value * countryrating *(other factors we decided to consider)

Very good idea is excellent and precise!
