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.

Gasoline

Deciding on gas and diesel can be tough, although

there are several reasons why you should 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.

4. Diesel engines will last 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 be ran on

vegetable oil.
