Torque vs. Horsepower

[Binder]

Het Bobbo not to pick on you but being that you're a ME could you tell us how much torque it took to accelerate a truck say 20,000 lbs from a stop to say 60MPH in a mile?

Where did Newton say torque?



I'm not following you on why the efficiency of different fuels has anything to do with the arrangement of cylinders but OK whatever.

OK whatever ... it's taking better advantage of longer stroke length. Better advantage of the high compression.

So a V8 with a even longer stroke would be even better right?

There isn't one when comparing similar applications.

So if there were one it would be better right?.....Stroke and static compression ratio are not a function of cylinder arrangement. You can compare specific 6's to specific 8's like we attempted to do in the other thread but you can't make a blanket statement like " a inline 6 is better than a inline 8 because a inline 6 has a longer stroke and higher compression".....Also are you sure a longer stroke is always better? Based on what? There's enough room in the engine compartment of a typical pickup to make the engine stroke a couple feet or so. Would this be better?:corn:

Not really for engine bore and stroke you also have to take into account rotational mass which would be insane on a couple foot stroke... For a small truck sized engine

No they aren't a function of cylinder arrangement.

But how else will you obtain the most potential from a diesel engine for a tow rig? A long stroke V8 will have more frictional losses to deal with that are associated with longer stroke engines. So you reduce the number of pistons to 6 and have a longer stroke than the typical V8 arrangement.

Where were we discussing inline 8 engines? :scratchhead:

what's the tire diameter?

The NET FORCE required to accelerate the vehicle is 455.95 lb.

Torque is F x r. Multiply this by the radius of the tire and that will give you the required torque at the wheel.

Pick a diameter it doesn't matter for the sake of our conversation.....

Hi everyone
this is way to deep for me, But good reading:corn:
