cool paper on BMW F1 engines

Thought some people might get a kick out of reading this, it was written by Super Mario several years ago. I came across it last night. It's an interesting read for F1 fans that geek out on the technical side of things.

Thanks for this! I can't imagine designing things to run for a certain number of *hours*; it's a fine line between long engine life and catastrophic failure.

Thanks, will take a read of this.

I did used to work for a manufacturer that made things to a certain life span, certainly was difficult to get the fine line

You can see one of these engines on display in the BMW museum in Munich.

Really intereresting, it's way smaller than you'd expect (than I expected at least).
All the connectors, barb fittings etc are also really small, way smaller than normal automotive connectors etc. Obviously to save weight, but it gives a bit the impression that it's a model scale engine
The clutch is also pretty interesting.

Yes, so the rods can stay on the centerline of the piston / cylinder bore, with the big end of the rods on a shared-journal crankshaft. So essentially bank offset also gives you width of the big ends of the rods.

Not to be confused with the so-called DeSaxe layout, where the bore centerlines are slightly offset (they don't point directly to the crankshaft axis).

At least that is my understanding.
