[Vwdiesel] Genset RPM and Diesels

[James Hansen]

I am still a DO NOT USE  TORQUE  -----use RPMs on these diesels.   They are
designed
as high speed diesels -----and as such they do not like high cylinder
pressures. ----AND read my lips  ----Gensets are notorious for opening the
throttle full
power on a load being applied.----------

yes.
I can't see the vw diesel lasting better at 1800rpm .  That's out of it's
peak efficiency range.  All you are saving with a vw-D by going low rpm is
the friction generated by the bearings, the difference between what it would
be at 3500 and what it is at 1800.  A fiddling amount really. It was
mentioned that at low rpm, the coolant was not very warm.  If that's the
case, that will kill an engine.  Restrict coolant flow or something to get
the engine warmer.
Hagar's right about the volks being a high speed engine. Speed and useable
torque is a function of displacement and cam profile, one of which the volks
doesn't have, and the other is the lobes are set up so the torque is
optimized around 2500
