A summary (in no more than 50 words) in idiot's inglish please...

Also see the same site for an alternative com system.

Gert, it is already in "idiot's English"....

....does that mean I'm an idiot 'cos I unnerstand it

Hi,

Basically what the oke wants to say is that your motor wears out faster if you run it with a lot of torque. Put it into motor car terms, if you drive up a hill with 70 km/h in 4th gear, your motor will wear more than if you drive up the same hill at 70 km/h in third gear. By driving up the hill in 4th gear the revs are low, and the stresses on the crankshaft, big end bearings, conrod and small ends are higher, than by using a lower gear, and revving the motor faster, and driving at the same speed. Generally internal combustion engines don't mind higher revs, obviously within their design parameters, but do mind loading, ie torque. So it is all a trade off between engine wear, fuel costs, reliability, operating temperature etc.

Incidentally, running the motor against compression, ie the throttle closed, but motor revving high, in car example braking downhill with the engine, or gliding the aerrie with throttle closed, also causes lot of wear in the engine.

P.s. Will I have now marks subtracted because it was more than 50 words?

Duck, then you must one clever idiot. Arnulf's inglish is more on my level.
thanks
