Sorry y'all... no tasty dinner tonight. It's leftover night.
That... and I bought Final Fantasy XIII yesterday, and have been playing the SHIT out of it. It's pissing the wife off something horrible, I can guarantee you that.
So... since there is no dinner, how about I give y'all some math instead...
Hooray for math!... LOL!!!
As many of you may or may not know, the rpms of the motor are measured off of the camshaft, and not the crank.
In a normal 4 stroke motor (90% of motors in cars today are 4 stroke), the crank spins 2 times for every 1 revolution on the camshaft.
So...
A normal rpm at idle is about 900rpm, that's 900 revolutions per minutes, or 15 revolutions per second, for the camshaft. It's 30 revolutions per second for the crankshaft.
That means that the pistons move up, and down, 30 times a second. At idle.
Now get this, F1 race cars have spun over 20,000 rpm during races. That is TWENTY THOUSAND revolutions per minute, or 333 revolutions per second, for the camshaft.
That is 666 (LOL) revolutions per second for the crank.
Six hundred and sixty six. The pistons move up and down, SIX HUNDRED AND SIXTY SIX TIMES PER SECOND at max rpm.
Sure, the F1 engine only has a stroke of 1.563 inches, but at 666 rpm, that equates out to... 86.7465 feet, per second. That's 29 yards, per second. That's a football field in just over 3 seconds.
86.7465 foot per second is 59 miles per hour. The piston is moving up and down, at 59 miles per hour.
Just think of all the other little shit that is going on inside that motor, that fast. The valves opening, and closing, 333 times per second.
Each spark plug firing 333 times per second.
Each fuel injector squirting fuel, 333 time per second.
Isn't math fun?
Maybe later I'll scare the shit out of all of you by telling you how many single bolts on a car there are that if they break, you die, or at least get seriously injured. Makes you wonder how a mechanic has the nerve to get in their car to drive home.

I totally didn't read about the engine math...sorry..add
