why is deisel better for hauling

[cschrempf1]

okay so i need good reasons on why diesels are better than gas for hauling (horse trailers) and why for a paper any good reasons?

#1 - Torque, it's All about Torque

Fuel economy.. My old gasser Hemi Dogde got under 10mpg towing anything. Yeah my diesel may get 13-14 towing, some get much better than that. But it's a LOT better than single digits.

Diesels are more durable than a gas engine. Larger bearings, and heavier internals are better suited for the increased engine load when pulling, therefore they last longer than a gas engine.

Diesel has almost THREE more megajoules per litre. That's a lot.
Diesels operate differently than gas motors.
Gasoline motors compress a air/gas mixture. The mix limits how much you can compress the air. Usually 9:1 compression.
Diesels compress ONLY air. Allowing for a much higher ratio. Somewhere around 18:1. That's double the air. Air allows for a more complete burn. Take a fire on the ground. You feel air getting sucked into it because it is using up air to burn the fuel, so other air must replace it. However, you still get smoke and other signs of incomplete combustion. Now, take a forced air forge. You pump air into it at the correct ratio, and it will burn VERY VERY hot with no visible smoke. Basic principle of combustion, no matter the application.
Couple the large amounts of air with the higher energy density of diesel, and that's the basic reason diesel motors are so much more powerful that gasoline motors.
Granted, they are heavier because of the high pressures inside them. So without working them hard, they don't get good mileage just because of the bulk of them. But if you load them up, they will not have a significant MPG drop as gas motors do.
As for the truck, you can buy a one ton, in either gas or diesel. The truck is the same. But the motor is what gives you such an advantage (or disadvantage) pulling anything.

more specifically, you don't have to spin a Diesel very fast to get the torque out of it. i have a 96er, peek torque is at 2000 rpm/65 mph.

U ever see a Peterbilt/Kenworth wit a gas engine...

That is what i was going to say ^^^


Diesels are better then Gas engines:

1 Power. More torque for moving heavy loads.

2 Effeceincy. Better MPG then Gas.

3 Longevity. Diesels are known to easily go for 1 Million miles.

one big advantage of diesel over gas is heat build up. A diesel uses air compression for power as gas uses a spark. I can drive 10 miles and the coolant temp has bearly moved. And we all know heat is an enemy of engines.

If you are happy with the gassers that you have pulled with do not drive a diesel
You will never be able to go back.
