What happens when the rpm's go above the peak power level?
I presume there is no damage to the engine to run rpm's up that high.
But what really occurs?
Is the perfect mix of fuel and air altered, or something?
I remember Marshall commenting that it was counter intuitive, but he read that running at high rpm's would improve fuel and engine efficiency.
Is the peak touque being adjusted downward purposely- for fuel savings and anti pollution reasons?
Is each succeeding diesel engine models - from the 220D to CDI- lowering the peak torque?
Just some wacky ponderings....
