Ah perfection! You answered the question I didn't know how to ask. I knew there was some other reason to use the engines that they do in semi's other than just to keep a low RPM for wear and tear purposes, just didn't know what it was. That explains it. Very good thank you.
Yeah so
SO I'll give a whole new scenario I think might be better. Take those same 2 engines. Hook them directly up to water pumps that circulate water through identical pools and pipes to get to the pools. Now have both of them pumping their maximum amount of gallons of water per minute that...
Ok, yeah in that imaginary scenario for me there were no differences in power reduction to the wheels due to the amount of gear teeth meshing per minute between the two or anything else like that, i was just wondering if horsepower truly is simply horsepower regardless of what the combination of...
Oh dang. I appreciate the quick math, that's honestly impressive. But what you're saying then is the answer is that they would slow down at the same rate?
Ok I'll try to be more specific while simplifying. If you had 2 identical semi's, and both were carrying a 30 ton load. But one had a regular 400hp diesel engine you'd see in a semi with it's standard transmission, the other had a 5.7 liter 400hp engine with only 350 lb-ft torque and a...
So basically I'm wondering if there's any benefit to having that much torque from a semi engine (vs say the relatively low torque you'd get from a 5.7 hemi with the same horse power) other than durability.
*it seems slightly odd that they would want to produce that much torque for such a relatively low amount of horsepower just for the sake of saving on wear and tear.
I think it would be exactly the same if the power band on a graph was the same shape on its way to reaching peak horsepower even though the stretch of rpm would be a lot higher on the gas engine. I think that because horsepower is power applied over time which makes it seem simple that it would...
If you took a 400 horsepower gasoline pickup engine and a 400 horse power semi engine and hook them up to a transmission so that they had the same output rpm while each engine is at their peak horsepower rpm would they be able to pull the same load fairly similar?
