There are some special diesel engines that will run
many fuels and will run on gas. But as a rule gas
will ignite way too early in the compression cycle
and explodes way to quickly to be used in a diesel.
Diesel fuel burns slower which allows it to push a
longer stroked piston down with a longer burn time.
This results in it pushing down on the piston for a
greater number of degrees resulting in higher torque.
A modern diesel of 300 HP will likely have a torque
rating of 1050 FP compared to a gas engine of 300 HP
which will have torque fairly equal to the HP numbers,
give or take a few. However a gas engine will now
turn up to 10,000 RPM and a diesel will usually run
up to around 3,000. This allows the gas engine to
develop large numbers of HP at the wheels through the
transmission and differential. While the diesel will
not have the advantage of that large gear reduction
they will be able to multiply the torque to the wheels
through large differentials, this pulls large loads.
Since the diesel fuel is oily and they turn less RPM
and are built heavy to maintain spinning torque and
centrifical force, diesels tend to last many times the
life of a gas engine. And while gas engines are great
for light work needing speed and don't tend to like to
be loaded a large percent of their life, diesels love
loads and infact are happiest in a loaded usage.
