Hi guys,
Specifications for engines seem to list kw & nm's - which seem to be achieved at different revs.
It's my understanding that the most efficient way to operate a diesel is to run it around peak torque.
If this is correct - for the CRD 3.0ltre manuals - what rev range should I be working to??
Many thanks
Guido
Peak torque will be close to the lowest revs ie the most load you can place on the engine and hold. Most efficient will depend a lot on you and how you use this power, but normally well above the peak torque range where the engine is more comfortable and not straining.
Drive it to peak power, change gears and it should drop down to peak torque in the next gear my ute has peak power at 3300 rpm and peak torque at 1600rpm.
A lot of power and torque can be felt/noticed when/if you drive by feel or sound of the engine. A diesel does not work the same as petrol, by that I mean don't shove the right boot to the floor to get going or get you over a hill. Start of feeding it what it wants then feed the fuel as it needs it. I drive mine this way with no problems. You'll feel the lack of power when too low in the revs but also run turbo temp up. A bit the same when you reach peak power it'll drop off.Quote:
