Gasoline Engines

Gas engines are known as internal combustion engines
and are divided into two general classes, specifically
two cycle and four cycle engines. A cycle of an
engine represents one stroke of the piston or one
half revolution of the crank shaft, as a complete
revolution represents two cycles. With a two cycle
engine, the power impulse occurs at each revolution,
while with four cycle engines it occurs at every
other revolution, hence the terms two and four cycle
engines.

Both classes have their own specific advantages and
uses. For autombiles, the four cycle engines is
most used. For motor boats on the other hand, the
two cycle engine is most often used.

The horse power of gas engines is designated as HP
and also brake test HP. The IHP is the theoretical
HP, which is found by figuring different formulas,
in which the diameter of the bore, length of the
stroke in inches, and number of revolutions per
minute form the basis for calculation. The results
are found by the use of such formulas.

The BTHP on the other hand, is the power the engine
actually develops in service, and is considerably
less than the IHP. Keep in mind, this depends upon
the degree of the mechanical perfection attained in
the construction of the same. If both the compression
and construction are good, the engine may actually
reach 80 – 88% of the intended IHP.

With gasoline engines, high HP and high RPM ranges
are what makes them popular. Gas engines have always
been more popular than diesel vehicles, for the simple
fact that they can achieve more speed. If speed
is what you are after, gasoline vehicles are what
you should be looking for. Although they may lack
in torque and raw power, they make up for it with
speed and tuning options.

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.

As soon as it is produced, diesel fuel begins to
deteriorate. Less than 30 days of refining, all
diesel fuel, regardless of the brand, goes through a
natural process called oxidation. This process forms
varnishes and gums in the fuel by causing the
molecules of the fuel to lengthen and start bonding
together.

Now, these components will drop to the bottom of the
fuel tank and form diesel sludge. The fuel will
begin to turn very dark in color, smell bad, and
cause the engine to smoke. The engine starts to
smoke as some of these clusters are small enough to
pass through the engine filtration and on to the
combustion chamber.

As the clusters begin to increase in size, only a
small amount of the molecules will get burned, as
the rest will go out the exhaust as unburned fuel
and smoke.

Its estimated that eight out of every ten diesel
engine failures are directly related to poor quality
and contaminated fuel. The build up of contamination
in the fuel systems and storage tanks can clog
filters, thereby causing the engine to shut down,
and damage to the engine to occur.

The number one reason for bad fuel is due to the
increasing popularity of diesel power and the
accompanying increased demand for more diesel fuel.
Long ago, diesel fuel remained in the refinery
storage tanks long enough to naturally seperate and
begin to settle, allowing the clean fuel to be
drawn apart. Now, with the demand getting higher
than ever, the fuel is never stationary long enough
to settle, and the suspended water and solids are
passed on to the person buying the fuel – you.

The changes in refinery techniques is also a
problem. In order to get more products, diesel
fuel is being refined for more marginal portions of
the crude barrel. This results in a lower grade
product that is thicker and also contains a lot
more contamination.

As time continues to pass and technology gets better
and better, one can only hope that the quality of
diesel fuel improves. As it stands now, the quality
isn’t good at all. If you run diesel fuel, all
you can basically hope for is that the fuel you
are getting isn’t contaminated.

Gasoline Credit Cards

With gasoline getting more and more expensive, you’ve
probably found yourself wondering what you can do.
Even with the rising costs of gas and fuel, you
still need it to go places. No matter how you look
at it, you are at the mercy of these prices.

If you own two credit cards, changes are that you
will use one of them to pay for your gas. Gas credit
cards are now starting to shine. There are many
individuals who are planning to apply for a gas
card. Most cards are either issued by a leading
credit card company or by a major retailing gas
station.

Along with that, there are some of the gas credit
cards that give you a great deal like having
discounts on gases such as unleaded, premium, and
others. Gas credit cards also give you an
assurance to have more approved gas bonus.

If the credit card is approved, the owner of the
card will not only save money on gas, but he’ll
also get an extra allowance for car equipment and
accessories. Gas cards can also help you save
a bundle on repairs as well.

Keep in mind that there are some things to consider
when you apply for a gas card. When you plan to
apply for a card, the conditions should always be
known. The benefits of the gas credit cards
available should also be studied and researched
in order to compare rates, features, and
benefits.

As the popularity of gas credit cards continue to
increase, so will the offers. Gas cards also
offer a positive effect for gasoline retailers as
well. The customer will also earn additional
incentives as well. If you plan to stick with
one brand of gas, this card can generate some of
the best rewards.

When looking for the best type of gasoline credit
card, the most important thing to do is review
the terms and conditions. The present status
of the card should also be reviewed in order to
avoid a bad credit record.

There are also several gas credit cards that will
give you extra rewards and point systems. What
this means, is that the card holder can earn
cash back on certain purchases. The more points
you get, the bigger product you can receive.

The ideal purpose of applying for gas credit cards
is to help eliminate the gas expenses. The
credit card should help you to have a deal with
gas expenses. Low interest premium cards can be
the best if you can maintain the proper balance.

The best thing about gasoline credit cards is the
fact that you don’t have to pay for them now and
you can just pay later. Just don’t forget to pay
the bill, as you could end up getting a bad credit
rating.

Gas Diesel Hybrid War

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.

Fuel economy
To put it into prospective, the fuel economy are
the numbers posted on the window sticker of a new
vehicle. Studies have shown that the average
driver only receives 75 percent or so of the
mileage figures that are on the sticker.

You can use these numbers to determine the best
type of vehicle for your purchase. The numbers
will let you know how many MPG your vehicle will
get, so you can compare vehicles and then go
from there.

Hybrid pricing
The gas electric hybrid vehicles are normally
priced higher than non hybrid counterparts,
anywhere from a couple of thousand dollars to
several thousand dollars.

Hybrids can get a lot of miles per gallon,
some averaging around 45 – 55. This is great
for those who want to save money on gas, as
hybrids can go many miles on a full tank of
fuel and they come with extended warranties
as well.

Diesel efficiency
Diesel powered vehicles are yet another fuel
efficient option. Diesels are known for getting
extra mileage from every gallon of fuel. They
offer much better torque than many gasoline
engines. The price differential they have
over gasoline engines are usually much smaller
than that of the hybrid.

With plenty of options available, you’re sure
to find what you need to help conserve fuel.
Before you make a purchase, always remember
to shop around and find what’s best for you.
