Interesting thing, - the torque.
From Gripen:
"Well, it's the output (hp, kW or what ever) which matters regardless what ever rpm torque combination is needed to produce that output."
Torque is measured in Nm/time. A horsepower is also a force in time, - if my memory is right, the force to lift 75 kg's up one meter in one second.
Torque has been explained to me as toughness, - i.e. Hp relative to RPM and the swiftness to get to the hp between various RPM's.
You would think it would be rather similar numbers, - but no. I remember 2 engines that were "in my service" at the same time.
One was a petrol engine, 1.6 l., Torque 90 nm, Hp 86, rpm probably 5000 at the time.
The other was a diesel, 3.86l., Torque 356 nm, Hp 90 at 2300 rpm. I belive the max torque was achieved at a lower rpm, but not sure. BTW, that was a turbo engine.
Any comments on that? There's got to be someone on the board that knows this from one end to another.
BTW, as a sidenote, the Diesel powered big things, while the petrol engine powered smaller, - the Diesel used quite a bit less fuel, - peaking out at 10L on the hour with full power.
