Diesel Fuel Quality
The designs of diesel engines striving to increase
performance have made a lot of advancements in engine
fuel delivery to the combustion chamber. The diesel
engines of today are much quieter, smoother, and
also more powerful. The quality of diesel fuel on
the other hand has not advanced at the same rate as
the improvements of engines.

Diesel Vehicles
As you probably already know, diesel engines get
better fuel economy than gas, simply because they
don't need to burn as much fuel as gasoline engines
to get the same amount of power. Diesel engines
are built heavier than gas engines, to help sustain
the added stress of the much higher compression
ratios.

Advantages Of Diesel Engines
If you've owned a diesel powered vehicle in the
past or if you own one now, you no doubt appreciate
the qualities this engine provides you with. More
torque, better fuel economy, and easier maintenance
are but a few of the attributes of owning diesel
powered vehicles.

Gav Diesel Hybrid Comparisons
These days, gasoline prices may be crimping your
your household budget. You may like to reduce
the U.S. dollars that flow to the Middle East for
oil, or perhaps you are motivated by your concern
for the environment, or even the nagging reality
that oil is a depleting resource that shouldn't
be wasted.

Diesel And Gas Prices
Over the years, the prices of both gas and diesel
have experienced some drastic changes which greatly
affects the cars and the driver itself. Many years
ago, the price of gas was around a dollar or a
little more, nothing like it is today. Back then,
gas wasn't high in price although the demand for
vehicles wasn't what it is today either.

Diesel Versus Gasoline
A diesel engine will go much farther on a gallon
of fuel that the standard gasoline engine
because of their designs, and due to the higher
energy density of a gallon of diesel fuel. But,
it also takes a bit more oil to manufacture a
gallon of diesel than a gallon of gas, with
the production and refining processes for
diesel producing more gases that trap heat.

General Information On Diesel Engines
Diesel engines offer the lowest specific fuel usage
of any other large internal combustion engine. The
fact remains, two-stroke diesels with high pressure
forced induction, particularly turbo charging, make
up a large percentage of the largest diesel engines.

How Diesel Engines Work
When gas is compressed, the temperature of it will rise,
with diesel engines using this very property to ignite
the fuel. Air is then drawn into the cylinder and
compressed by the rising piston at a much high
compression ratio than gas engines, up to 25:1, with
the air temperature reaching 700 - 900 degrees C.
