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.

Therefore, when you consider the relative merits

of deisel and gas cars, try knocking the MPG

estimates for the diesel car down by 20 percent.

A diesel vehicle will cost you a bit more,

so you'll get more bang for your buck from a

gasoline vehicle.

The nasty rumors you hear about diesel are

true as well - diesel is less refined than gas,

or in other terms it's dirtier. Diesel

vehicles also emit more particulate matter and

NOx, both of which are serious health hazards

and air pollutants. Current diesel engines are

more polluting per each mile they are driven

than gas engines.

Using biodiesel on the other hand, will improve

this situation. If biodiesel is available in

your area, you'll still need to examine

whether a diesel is the right vehicle for you.

When you consider the facts, you have to ask

yourself which models you can afford, what is

the MPG, will engine be succifient for you,

and the number of passengers the vehicle will

accommodate. Then, given your budget, you can

go from there.

There are numerous gas and diesel vehicles

available, all you have to do is decide which

one is right for you. If you research carefully,

you'll have the perfect vehicle for your entire

family.

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.

Are you tired of the continuing rise in gasoline price?

If you are, you're not alone. In this article, you'll

find a few excellent tips designed to help you save

a bit of your hard earned money.

First, its always best to purchase your gas either

first thing in the morning or late at night. The

reason for this is because gas is denser at a cold

temperature, so you'll basically be getting more for

your money.

Secondly, check your local gas prices to find the

best price available. You can check your local gas

prices online as well, which will prevent you from

wasting gas while driving around to look for the

best price.

By keeping your car well maintained, you can help

improve fuel consumption. By simply tuning your car,

you can decrease your fuel consumption by up to 20

percent. Also, you should keep your tires properly

inflated and aligned. Tires that are under inflated

will cause fuel consumption to increase by 6 percent.

You should also make sure that you change your oil

and air filters on a regular basis as well.

Other tips to keep in mind are to drive by staying

in the posted speed limits, as the faster you drive

you will use more fuel. Whenever possible you should

use overdrive, as this will help fuel and also

improve the wear on your engine. You can also

combine your errands by making a list of things that

you have to do, as the more you cold start your

engine, the more fuel you'll be using.

By taking the time to do these tips, you'll be

amazed at just how much fuel you can save. Gas

prices are becoming ridiculous these days, which

is why you want to do your part to converse little

drop that you can.

Hydrogen Boosted Gas Engines

(category: Diesel-VS-Gasoline-Vehicles, Word count: 486)
Share this article on: Facebook, Twitter, Whatsapp

With the ever increasing cost of gasoline prices,

auto makers are having to work overtime to cost

effictively improve the fuel economy, while still

meeting the strict emission requirements of today

with gasoline engines.

One ideal and promising way to boost the fuel

economy of gas engines is to add hydrogen to the

fuel/air mixture in the engine. Since hydrogen

isn't available at the local gas station, selling

a hydrogen boosted gas engine wasn't on the list

of engines - until now.

Lack of emission

A major cost and environmental advantage to hydrogen

boosted gas engines are low amounts of NOx emission

gas, which will completely eliminate the need for

external NOx emissions control. Currently, NOx

emissions control is a major cost problem for diesel

engines which use expensive traps to meet the

emission standards. Diesel engines particulate

emissions that must be collected by a filter that

should be changed periodically.

Hydrogen boosted engines on the other hand require

neither NOx or particulate control and require only

a low cost oxidation catalyst to control very small

amounts of exhaust which is formed mostly during

the engine starting up and warming up. Additional

cuts in emissions control requirements stem from

the engine's ability to use only the clean hydrogen

enriched charge during the cold start phase when

90% of emissions are generated in the emission test.

Cost

The hydrogen boost system is effectively a bolt

on technology that can be added to an existing

vehicle's engine compartment. According to those

developing the system, the cost of the system is

less than half of the added cost for diesel.

The future

Prototype hydrogen boosted engines are now be

installed in test SUV vehicles that have

sufficient space for the reformer and it's related

system. The start of long term road testing

for performance, reliability, and durability

information is planned for later on in the year

before the system goes further into development.

Four cylinder gasoline engines will likely be the

prime candidates for the technology as high gas

prices continue to generate competition among the

higher fuel economy models that seek MPG

leadership.

With gas prices getting higher and higher, hydrogen

boosted gas engines offer you the chance to get

more miles per gallon and not have to worry about

burning up all of your fuel. Instead of having to

go out and buy a diesel to conserve fuel, hydrogen

boosted units will help you preserve gas.

Even though they aren't available to buy right now,

they will be very soon. Many manufacturers are

looking into them, as they offer gasoline engines

something like never before. If you own a gas

powered vehicle and have thought of giving it up

to go diesel, you might want to think again - as

hydrogen boost units may change the world of gas

engines forever.

Why You Should Choose Diesel

(category: Diesel-VS-Gasoline-Vehicles, Word count: 300)
Share this article on: Facebook, Twitter, Whatsapp

The major distinction between diesel and gas lies in

the type of ignition. While gas engines operate on

spark ignition, diesel engines employ compression

ignition for igniting the fuel. With compression, the

air is drawn into the engine and subjected to high

compression that heats it up. The result is a very

high temperature in the engine, much high than that

of gas engines.

In diesel engines, air and fuel are both infused into

the engine at different stages, as opposed to gas

where a mixture of air and gas are introduced. The

fuel is injected into the diesel using an injector

where in a gas engine, a carburetor is used for this

very purpose.

With gas engines, fuel and air are sent into the

engine at the same time, then compressed. The air

and fuel mixture will limit fuel compression, and

thereby hence the overall efficiency. Diesel engines

only compress air, and the resulting ratio can be

much higher.

Advantages

Diesel engines are much more efficient and

preferable as compared to gas engines due to the

following reasons:

1. Diesel engines have overcome the several

disadvantages of earlier models that featured higher

noise and maintenance costs. Now, they are quiet

and require less regular maintenance when compared

with gas engines of a similar size.

2. Diesel engines are more rugged and reliable.

3. There is no sparking at all as the fuel

ignites. The absence of spark plubs or spark

wires also helps to lower maintenance cost.

4. The fuel cost produced is 30 - 50 percent

lower than gas engine fuel prices.

5. Gas burns hotter than diesel, and

therefore they have a shorter life span when they

are compared with diesel engines.

Diesel Fuel Quality

(category: Diesel-VS-Gasoline-Vehicles, Word count: 450)
Share this article on: Facebook, Twitter, Whatsapp

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.

General Information On Diesel Engines

(category: Diesel-VS-Gasoline-Vehicles, Word count: 423)
Share this article on: Facebook, Twitter, Whatsapp

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.

Throughout North America, diesel engines are generally

used in larger trucks, where the low stress, high

efficiency cycle will lead to a much longer engine

life and lower costs to operate. These advantages

also help to make the diesel engine ideal for use in

the heavy haul industry.

Cars however, continue to use gasoline, primarily

due to the consumer desire for a wider range of

RPM. In Europe, the use of diesel engines with cars

is far more common.

Even though diesel engines are more efficient when

throttled down, they aren't suitable for most types

of aircraft. The higher compression ratios of the

diesel cycle demand a much stronger block, head,

and almost all moving parts in general. These

stronger parts add a lot of weight, or a lot of

expense, especially if lighter alloys are being used.

The Otto cycle engines are much cheaper to build for

these reasons, although they have long been overtaken

by the turbine engines. For the same displacement

of the engine, Otto cycles will produce more actual

power than a Diesel cycle can, because the fuel

will burn at a much faster rate, allowing more power

strokes per minute than a standard diesel can offer.

What this means, is that less fuel has to be carried.

Additionally, commercial aircraft is normally run

at preset limits, so that Otto cycle engines used

in aircraft don't suffer anywhere near the efficiency

penalties that land vehicles do. Heavy equipment,

such as those used in mining and construction,

almost always uses diesel engines.

Diesel engines are also used with submarines. In

these types of submarines, the diesel engine is run

when the submarine is on the surface, which charges

the batteries that power the submarine once it is

submerged.

All across the world, diesel engines serve many

different purposes. They are used with almost all

types of heavy machinery, and other vehicles. Gas

isn't the way to go with heavy machinery, as the

engines simply can't withstand the beating.

Diesel has been popular for many years with machinery

and submarines, simply because the engines can

last for years and years. Although they won't offer

as much speed as gasoline, the torque and power is

still there.

Why People Use Diesel

(category: Diesel-VS-Gasoline-Vehicles, Word count: 420)
Share this article on: Facebook, Twitter, Whatsapp

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.

Gas Trucks Versus Diesel Trucks

(category: Diesel-VS-Gasoline-Vehicles, Word count: 444)

If you plan to use your truck like a car, desiring

quick, quiet acceleration and rarely ever haul a

heavy load and don't plan to it for a long time,

you may want a gasoline engine. Gas engines run

smoother, fuel is easier to find, and gas

engines start easier in cold weather.

If you plan to use your truck for towing, value

good fuel economy and plan to put plenty of miles

on it, you may want a diesel. The price to buy

a diesel truck is really high, although they can

offer you a lot in return.

Below, you'll find the leading vehicle manufacturers

and what they offer you.

Dodge

The 2500 and 3500 Dodge Ram Heavy Duty trucks are

the newest 3/4 and 1 ton trucks on the road. Back

in 2002, the Ram didn't have enough power with

the 245 HP 9.5L. Dodge promised more powerful

engines for the 2500/3500 platform and they

delivered on that promise.

The new base engine is the 5.7L gasoline V-8

that's not only the most powerful engine of the

group at 345 HP but also revives the well known

and historical Hemi name.

Ford

Ford helped push the 3/4 ton and 1 ton truck

market to where it is today when it introduced

it's international engineered power stroke

diesel back in 1994. Before 1994, these diesels

were poorly built and no match for the big

inch gasoline engines.

From 1994 to 2002, over 70% of super duty Fords

were sold with the optional 7.3L V-8 diesel

engine. This engine helped to put Ford among

the leaders in diesel trucks, as they had more

than they needed to dominate the market.

Chevrolet/GMC

The GM 2500/3500 twins Silverado HD and Sierra

HD both come standard with GM's 6.0L gas engine

V-8. This engine is ideal for 3/4 ton trucks

where towing isn't a concern. The upgrades

start with the 8.1L gas V-8 that's based on

Chevrolet's venerable big block engine.

Over the years, diesel trucks have proven to be

effecient with mileage, great for towing, and

easy on maintenance. Unlike gas engines, diesel

engines do not have spark plugs, which means

you won't need to get them tuned up near as

much as gasoline engines.

For those who like to haul heavy loads on a

frequent basis, diesel is the way to go. You

can get quite a few miles per gallon, and

diesel trucks are built to go 250,000 miles or

more before the engine needs to be rebuit,

making them a purchase that is more than worth

your money.
