Gas Tractor Versus Diesel Tractor

There are many different reasons as to why a diesel

compact tractor is superior to a gasoline garden


First of all, the diesel engine doesn't have the

parts that normally wear out or give problems. There

are no spark plugs, rotors, points, or distributor

caps like the garden tractor. There is no carburetor

either, that will gum up and be hard to start after

being stored for a long period of time. Diesel engines

can be stored for long periods of time and still start

right up.

Secondly, diesel engines in most tractors are water

cooled. This will allow the engine to run at a more

consistent and cooler temperature, which will extend

the life of the engine. The typical properly

maintained diesel engine can run thousands of hours

without breaking a sweat - and without having to be


Diesel engines will also make more power. Even though

gasoline tractors may be a little quicker to start

with, they can't begin to match the power and raw

torque that diesel engines offer.

Another reason why diesel tractors are better than

gas is the available attachments. Most gasoline

tractors are equipped with a belly mower and don't

normally have a three point hitch. This will severely

limit the type of implements that you can use and

also limit the tractors expandability.

Most blades and scoop implements won't work with a

gasoline tractor. The drive train will also limit

the type of implement you can use with a garden

tractor. The typical gasoline garden tractor is

belt driven, while a belt drive won't pull as much

load as a diesel powered tractor. You would probably

not be able to use a box blade or tiller either

with the average gasoline powered tractor.

Both diesel cars and light trucks are receiving a

lot of attention in the United States as a near

term strategy to achieve fuel economy and climate

change goals.

The renewed interest in diesel as of late stems

from its potential to improve passenger vehicle

fuel economy. The best diesel passenger vehicles

of today are more efficient on fuel than their

gas counterparts, helping to reduce carbon

emissions by 30 percent or more.

There are some auto makers that are talking about

re-introducing diesel into light duty markets as

a solution for reducing global warming pollution

from both cars and trucks. Another important

reason is that the higher efficiency of diesels

will provide a quick fix for manufacturers who

are struggling to meet federal fuel economy

standards for light trucks.

Even if the efficiency benefits of diesel do

yield real world improvements on the economy, the

potential climate change benefits are modest.

Even though diesel achieves more miles per gallon

than gasoline, many are concerned about the

impact that diesel passenger vehicles have on

the economy. From time to time, the combustion

in the engine can cause black emissions to spit

from the exhaust, which is actually very bad

for the economy.

While gas is actually the worst, diesel is taking

strides to improve engines and the impact on

the economy. Diesel is getting more and more

popular these days, as gas prices continue to

rise and rise.

Although diesel engines can have an impact on

the economy, they are the way to go for those

looking to conserve mileage. Diesel vehicles

cost more than gas vehicles, although they will

offer you more than you can expect. If you are

looking for a quality ride, diesel is the way

to go.

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.

Gas Vs Diesel Boats

(category: Diesel-VS-Gasoline-Vehicles, Word count: 441)
Share this article on: Facebook, Twitter, Whatsapp

As you may know, diesel engines aren't something

you should take lightly. There are good reasons

why the rush to put them in cars back in the 70s

flopped. Diesel isn't the ideal power source for

all applications.

Engine speed

Diesel engines gained the reputation for long

service life early on in the history of the

engines, mainly from engines that were used in

commercial operations. These were big, very

slow to turn engines that were usually in the

600 - 1,000 RPM range.

The long service life of the diesel engine isn't

really a myth when used in the proper application.

It's only a myth in pleasure craft, where the

engines are operated in-frequently at high and

low speeds, normally under very heavy loads and

adverse conditions.

Fuel consumption

If you plan to engage on some serious long range

travel, especially if fuel stops aren't available,

then fuel consumption will become an issue.

Diesel engines will normally burn 1/3 to 1/2 the

amount of fuel as their gas equals. Considering

the cost of the engines versus the amount of

fuel you'll burn during the time you own the

boat, fuel savings isn't really important.


Most questions of choice arise for boats that

are in the 28 to 34 foot range where either type

of engine is available with adequate horsepower.

Gas engines do have the advantage that they are

cheap to buy and also cheap to repair.

Diesel boats are just the opposite, as for the

price of one you could buy three gas engines.

For the price of a smaller in-line 6 cylinder

diesel, you can buy two gas engines.

Therefore, cost wise, unless you really need

diesel power, diesels aren't very practical.

The advantage to diesel comes only at the

point where the extra torque is needed because

a gasoline engine would simply be under too

much strain to have an adequate amount of

service life.

If you have a choice of gas versus diesel,

your first concern should be to determine

whether or not you can really afford to own a

diesel, as the initial price is only part of

the cost.

If you simply can't afford to write a big check

for routine maintenance, then you will probably

be better off going with gas. On the other hand,

if you have a lot of money, diesel would be

your best bet. Diesel engines are great to

have, although they cost a lot of money to

up keep and they generally aren't the way to go

for those on a budget.

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


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.

Gas Versus Diesel

(category: Diesel-VS-Gasoline-Vehicles, Word count: 484)
Share this article on: Facebook, Twitter, Whatsapp


Due to the high compression ratios and resulting

high cylinder pressure in diesel engines, they

must be built to withstand a lot more punishment

than gas engines. The parts that are spruced up

include a thicker block and cylinder heads,

pistons, crankshaft, and valves, which can be

very costly indeed.

When it comes to the price, gas wins this one by

far. Diesel costs a lot more to own than gas,

which is one of the main reasons why people tend

to choose gas over diesel.

Fuel cost

Diesel fuel is easier to refine, taking less

time to get from raw petroleum to final product

from gas, giving it a lower price than that of

gas. On the other hand, within the United States,

diesel is priced the same or just a bit below

regular unleaded gas.

Noise and vibration

Despite many improvements in noise isolation and

engine noise technology in trucks over the last 10

years, diesels are still much louder and shake

more than gasoline powered vehicles. At idle, the

clatter and shake of diesel vehicles are clearly

noticeable, while it can be hard to tell if the

gas engine is even running.

Cold weather

If you've tried to start a diesel engine on a

cold day, you know that gas is by far easier to

start. Diesels don't have spark plugs like gas engines

do, as the fuel is ignited once it's injected into

the cylinder that is already under pressure.

When it gets cold, the air isn't hot enough to

ignite the diesel fuel.


Maintenance on a diesel vehicle is more expensive,

thanks to many things including the larger volume

of oil in the engine and the fact that fuel filters

and water separators must be serviced more often

than gas vehicles. Gasoline engines have a bigger

advantage due to extended service periods on spark

plugs, engine oil, and even antifreeze.

Making that final choice between gas and diesel comes

down to what you'll do with your vehicle and where

you live. If you use your vehicle for quick, fast

acceleration and rarely ever haul heavy loads, and

don't plan to keep your vehicle past 100,000 miles,

you may want to consider buying a gasoline vehicle.

Gas runs smoother, fuel is easier to find, and

they are easier to start in cold weather. On the

other hand, if you plan to tow, value good fuel

economy and plan on racking up a lot of miles, then

you'll want to buy a diesel.

Price is also an important consideration, as diesel

vehicles can be a bit more expensive than gas. If

you aren't worried about price, then diesel may be

your best bet. For trucks, diesel is by far the

superior choice for those who like to haul heavy

loads on a frequent basis.

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.


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.

Diesel Engines Forgotten Treasures

(category: Diesel-VS-Gasoline-Vehicles, Word count: 418)
Share this article on: Facebook, Twitter, Whatsapp

There are very few engine configurations that promise

increased fuel economy and power. There are few

engines that offer this in addition to reliability.

Today, those across the ocean are enjoying the

fruits of diesel technology revolution.

Diesels have experienced a great history here in the

United States. In 1980, General Motors modified

their 350ci gas V8 to run on diesel fuel. The result

however, wasn't that god. These engines offered

better fuel economy but little else. They were

very slow, and not very reliable.

Mercedes Benz on the other hand, had better luck

in the 1980s with an array of vehicles available

with diesel engines. These great vehicles offered

amazing durability although they were rough, noisy,

and smoked quite a bit. Volkswagon offered diesel

as well, although they had a habit for spewing

blue smoke from the tail pipe.

Throughout the 90s, Benz and Volkwagon offered

diesel vehicles in the United States, with each

generation becoming cleaner, smoother, and more

powerful than the last. Overall, they were a

tough sell as they still lacked the horsepower

that many were seeking.

Today, Mercedes, BMW, Jaguar, Volkswagon, Ford,

and many other manufacturers are offering diesels

to many markets throughout the world. To put it

simple, forget everything you know or think you

know about diesel engines in the United States.

These newer engines benefit from hundreds of

technical innovations. There are several diesels

in Europe that offer better acceleration than

their gasoline counter parts. BMW's 120d has

163bhp, goes 0 - 60 in under 8 seconds, and

achieves 49.6 miles per gallon.

Benz offers the C320 CDI SE that has 224bhp, and

over 360 lb foot of torque. This car gets just

under 48 mpg on the highway, with an acceleration

of 0 - 60 in under 7 seconds. Throughout North

America, you won't find a gasoline engine that

offers this unique blend of fuel economy and

excellent performance.

The reason why diesels haven't caught on in

North America comes down to one word - sulfur. We

have too much sulfur in the diesel here in the

United States. This cheap grade of diesel fuel

will run havoc on the more sophisticated diesels

offered overseas and cause an increase in


There is hope however, as refiners will soon be

producing what is known as ultra low sulfur

diesel fuel. This will help to reduce the sulfur

content from 500ppm to 15ppm.

Diesel Versus Spark Engine Ignition

(category: Diesel-VS-Gasoline-Vehicles, Word count: 482)
Share this article on: Facebook, Twitter, Whatsapp

As you may already be aware of, diesel engines are

more efficient than gasoline engines of the same

power, resulting in much lower fuel usage. For an

efficient turbo diesel, the average is 40% more miles

per gallon. The higher compression ratio with

diesel engines help to raise efficiency, but diesel

fuel also contains around 15% more energy per unit

volume than gas.

Diesel engines that are naturally aspirated are far

more massive than gasoline engines of the same power

for two reasons. First, it takes a larger capacity

diesel engine than a gas engine to produce the same

amount of power. Essentially, this is because the

diesel can't operate as quickly. The rev limit is

slower, because getting the correct fuel to air ratio

into a diesel engine fast enough is more difficult

than a gas engine. The second reason is due to the

fact that a diesel engine needs to be stronger to

withstand the higher combustion pressure needed for


Diesel engines also produce very little carbon

monoxide as they burn the fuel in excess air except

at full loading capacity, where a full quantity of

fuel is injected per cycle. They can however,

produce a black soot from the exhaust, which consists

of unburned carbon compounds.

Often times, this is caused by worn injectors, which

don't atomize the fuel sufficiently enough, or a

faulty management system that allows more fuel to be

injected that can then be burned with the available


For commercial use that requires towing, diesel

engines tend to have more desirable torque. Diesel

engines tend to have their torque peak quite low

in their speed range which provides smoother control

over heavy loads when starting from rest, crucially

allowing the engine to be given higher loads at low

speeds than a gas engine.

The lack of an electrical ignition system in diesel

engines improves the reliability. The high durability

of diesel engines is also due to the overbuilt

nature as well as the combustion cycle, which will

create a less violent change in pressure when

compared to a gasoline type spark ignition engine.

Diesel fuel is also a better lubricant than gasoline,

so it is less harmful to the oil film on piston

rings and cylinder bores - making it routine for

diesel engines to go 250,000 miles or more without

having to be rebuilt.

For several reasons, diesel proves to be better than

spark engine ignition. Diesel engines last a lot

longer, they offer more torque, and they are also

more reliable. They are also more expensive as well,

although you get what you pay for. If you have

never owned a diesel vehicle, you owe it to yourself

to see everything they offer you - and you'll find

yourself a very satisfied customer.
