									Why People Use Diesel

With diesel engines, the compression ratio is higher and there is more
power. From a technical point, the compression ratio of an engine is the
comparison of the total volume of the cylinder at the bottom of the
piston's stroke divided by the volume of the cylinder remaining at the
top of the stroke.

Gasoline ratios

Serious damage to gas engines can occur if you attempt to run a high
compression ratio with a low octane type of fuel. Detonation is the
ignition of the fuel due to the high temperature caused by a high
compression ratio that is developed by design. The fuel is ignited prior
to the spark of the plugs that result in a rapid, yet uncontrolled
burning.

Diesel ratios

Keep in mind, the diesel is a heat engine, using heat developed from the
compression of air. High compression ratios are possible since the air
is compressed. The hot compressed air is sufficient to ignite the diesel
fuel when it's finally injected near the top of the compression stroke.

Diesel engines

Fuel and air in the design of diesel engines are not premixed outside of
the cylinder. Air is taken into the cylinder through the intake valve
and then compressed to make heat. The diesel fuel is injected near the
top of the piston's stroke in an amount or ratio that corresponds to the
load on the engine.

Heavy duty

The higher compression ratio causes engineers to design, and test the
block, heads, head bolts, crackshaft, connecting rods, rod bolts,
pistons, piston pins, etc., with a greater range of structural capacity.
To put it in other terms, diesels are heavier than gasoline engines.

Deciding between gas and diesel can be tough, although   there are several
reasons why you might want to use diesel.

1. Diesel engines produce twice the power per gallon of fuel than
gasoline.

2.   A gallon of diesel is normally cheaper than a gallon of gas.

3. Diesel fuel doesn't blow up. The fact is, its hard to get diesel to
burn at all. That makes it a lot safer in auto accidents.

4. Diesel engines can last up to four times longer than gasoline
engines.
5. Diesel fuel that is untreated will last longer in storage than
untreated gasoline.

6. Treated diesel fuel will last longer in storage than treated
gasoline.

7.   Diesel fuel treatment will cost less than gas treatment.

8. Spoiled diesel can be reconditioned to refinery specifications, as
spoiled gas can't.

9. Unmodified diesel engines can theoretically be run on vegetable oil
(but don't try this at home!)
