Am I the only one that just HATES inaccurate computer animations? I mean, yes, it gets all the points across... but really. Cam lobes on the CRANKSHAFT?!?!? And a fuel being injected through a spark plug!
Its as bad as an oil company commercial that ran during NASCAR races a year or so ago that appeared to show two pistons attached to counter-rotating crankshafts, and had both the intake and exhaust valves move at the same time.
