Diesel vs gas......................
OK folks, there have been a few to many diesel vs gas threads that have shall we say gone to "Hell and a hand basket"! So if all of you would put in you BEST, no flaming reasons for going gas vs diese...

Roadfrog - I can only imagine that you are trollling here.(sic)
BertP,
This was un-called for and completely off base. I have learned more from people like PSDExcursion, TinTipi and Roadfrog (to mention a few) than from you. I spent a day reading through the results of a google search on this phrase "diesel vs gas" and have come to a better basic understanding of the issues that you seem to have, from reading your posts. Seems to me like you are the better troll candidate, except I believe that in you mind you are presenting what you honestly believe to be the case.
Your comparison to turbine engines in tanks is just silly and useless when we are talking about diesel engines in PUs or SUVs used for towing trailers. Engines are designed for different purposes you can't go willy-nilly comparing different engines designed for different applications.
The major item which put you on my ignore list for this topic is a post I read where you claim torque is "nothing" and HP is everything. You have that completely backwards, anyone informed knows that engines supply torque; HP is just a figure indicating how that torque is being applied (to a load) over time. Without torque there is no HP.
Anyway, HP is just a power measurement in terms of the power of a horse. If we just want the power of an engine (not in terms of HP) It is simply: power = torque * RPM. Again, for engines, HP is nothing in and of itself, we don't need it to characterize power. But if we want to see how much power the engine is generating compared to the power supplied by the average horse (550 ft-lbs/sec) you must multiply the above by the conversion factor of 1/5252.
Plain and simple, for engines:
- Torque is the force supplied by an engine (This is what allows loads to be moved)
- HP is a measue (relative to the power supplied by a horse!) of how that torque is applied over time.
What the specs say is this: Gas engines supply their available torque faster than a diesel (they are designed that way) but a diesel can supply more torque.
