Diesel And Gas Prices

Over the years, the prices of both gas and diesel have experienced some drastic changes. 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.

As the demand for vehicles grew, the demand for fuel grew as well. Other actions and events have played into the equation as well, resulting in the rising costs of fuel. Fuel is something we all need to run our vehicles, as we wouldn't be able to go anywhere without it.

As you may know, a majority of the gas we get at local gas stations comes from overseas, primarily the Middle East. Therefore, we have to pay taxes and such on the gas we use, which pays for the gas as well as the shipping. If we got our gas from within the United States, one can't help but wonder whether or not the prices would indeed be lower.

Diesel on the other hand, has always managed to keep a price lower than gas. Diesel comes from within the United States, so the prices are of course going to be lower. The only problem associated with diesel fuel is locating it, as many gas stations don't sell it.

When it comes to the choice between the two, diesel fuel is obviously cheaper to buy. Gas is in supply more, which means that you can find it almost anywhere. If you own a gasoline vehicle, you obviously don't want to put diesel in it. If you own a diesel vehicle, then you of course wouldn't want to put gas in it either.

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.

Diesel Engines And Well Known Gas

In passenger cars, the diesel engine has never really caught on. During the middle to late 70s, diesel engines in passenger cars did notice a surge in sales due to the OPEC oil embargo, although that is the only real significant penetration that diesel engines have made in the market.

Although diesel engines are more efficient, there are eight historical problems that may have held them back.

  1. Due to the higher compression ratios, diesel engines tend be heavier than the equivalent
    gasoline engine.
  2. Diesel vehicles and diesel engines tend to be more expensive than gas.
  3. Because of their weight and compression ratio, diesel engines tend to have lower RPM ranges than gas engines. This gives diesel engines more torque rather than higher horsepower, and this tends to make diesel vehicles slower in terms of acceleration.
  4. Diesel engines have to be fuel injected, and in the past fuel injection was very expensive and less reliable.
  5. Diesel engines tend to produce more smoke and smell very funny when compared to gasoline engines.
  6. They are harder to start in cold weather and if they contain glow plugs, the diesel engines
    may require you to wait before you start the engine so that the glow plugs can heat up.
  7. Diesel engines are much noisier than gas engines and tend to vibrate quite a bit.
  8. Diesel fuel is less available than gas.
Although one or two of these disadvantages would be acceptable, a group of them is a big turn away for many people.

Even though the list above are reasons in the past as to why diesel never really took off, you can
expect these reasons to get corrected and improved in the future, meaning that you will see more and more diesel vehicles on the road.

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.

However, there are some motorists that still complain about the engine's weak power, especially when accelerating from a full stop. What you may not be aware of is the fact that a diesel engine can be tweaked to give more power without harming the fuel economy.

Diesel engines use air compression to create combustion versus the fuel/air mixture that is required by gas engines. This attribute means that diesel engines don't require spark plugs and therefore don't need to be tuned up.

Diesel fuel has a much high fuel density than gas, which results in fuel economy increases of 20 - 30% over gasoline powered vehicles.

Diesel engines are also cheaper to maintain as they have less parts than that of a gasoline powered engine. The life span of a diesel engine is also much longer.

If you're looking for torque, for pulling a boat or other equipment, then the diesel engine has the supreme advantage. Diesel engines are surely slower, especially when starting from a dead stop, although when you climb hills or go over bridges, the diesel engine is surely up to the task.

With trucks, diesel is normally the leader over gas engines in terms of performance and miles per gallon. Diesel trucks will get more miles than gas trucks, and the price for diesel is a bit cheaper than gas these days. And with gas prices on the rise, diesel will continue to dominate for a long time to come.

A Pioneer In Their Own Right: The Pioneer Car Stereo

Look at any good car stereo system and you’ll probably see a Pioneer car stereo unit plugged into the console. Alongside with quality speakers and a strong lineup of accessories like LCD panels and navigational devices, Pioneer products/Pioneer car stereos have earned a huge following the world over.

The Pioneer Company is a Tokyo-based corporation, and is one of the world leaders in digital entertainment products. The Pioneer Company was first founded in 1938 in Tokyo as a small radio and speaker repair shop business but today, they are recognized as a leader in technology advancements in the consumer electronics industry.

The company is truly deserving of their name. They are respected for many innovations such as interactive cable TV, the Laser Disc player, developing the first Compact Disc player for the car and the first detachable face car stereo, DVD and DVD recording, plasma display, and organic electroluminescent display. Their strength in optical disc and display technology is complemented by its state-of-the-art software products and manufacturing capabilities.

Nowadays, Pioneer car stereo units are not just simple head units. A car stereo can easily be comprised of several items built into the console of the car. Hardware like navigational devices, DVD players with LCD panels, coupled with the standard array of compact disc, mp3 and cassette players now usually go together. One would be hard-pressed not to acquire all of these, as it is such a delight to see these units work harmoniously. But traditionally, a Pioneer car stereo unit is a head unit with a radio, cassette and cd player. No matter how bare-bones this might sound, anyone will surely be impressed with the sound quality and features a Pioneer car stereo can boot.

Something like the DEH-P90HDD Pioneer car stereo single CD player head unit. The DEH-P90HDD allows you to record CD Audio (from the unit itself or from a changer) onto a 10GB hard disc drive, which holds about 200 audio CD's (using ATRAC3 digital compression). Your CD's are recognized by the pre-installed Gracenote CDDB database, which includes auto-playlists that make finding a specific CD easy. This Pioneer car stereo unit can also play your MP3 CD's plus CD Audio, CD-RW, and CD-R discs. Also, the MagicGate Memory Stick player lets you play recorded Memory Stick tracks. The Organic EL display is easy to read and accepts image downloads, so you can customize its look. Built-in DSP offers a 13-band graphic EQ and a huge variety of tools. The DEH-P90HDD is XM Ready and provides a steering wheel remote.
If cassettes are your thing, the KEH-P4020 Pioneer car stereo cassette player head unit is a good product to choose. It is a full logic cassette system with multi-color display, 45Wx4 High Power, EEQ™ equalizer system, Tuner, IP-Bus System Control, flap face and has a detachable face security.

If you’re planning to buy a Pioneer car stereo unit, why not match it with a set of Pioneer speakers too? Pioneer car stereo has made another innovation in their REV Series speakers, which incorporates technological breakthroughs in their IASCA award-winning Premier Reference Series (PRS) speakers. Rev Series speakers boast Pioneer’s Kevlar Fiber Composite Cones, Soft-dome tweeters and Wave guides. Each speaker features a bright yellow cone and distinctive wave guides, plus a six-spoke grill with a titanium finish that simulates chrome wheels.

With all these impressive products, is it still a wonder why they call Pioneer car stereos “Pioneer”?

Car Stereo Speaker: Let Your Car Stereo Speak For Itself

Even if you’re not a car audio connoisseur, it’s easy to be impressed with a car stereo speaker while looking around in an expo or convention. They’re the first thing you’ll probably notice, they come in different colors, shapes and sizes. Those big throbbing concaves blaring incredibly low bass lines or cool little tweeters whistling out seething treble sounds.

Car stereo speakers are interesting and very tempting to buy, especially the big loud ones. But big is not always the best. Each speaker has its own unique quality, intended use and price range. Some may also be better than others at certain things so it pays to investigate your type of car stereo amplifier or head unit before you finally decide on a car stereo speaker for your system. Here are some features to consider:

Car stereo speakers are not all the same size and wattage, and this can cause a problem once you try to hook it up in your car. Know the specs of your system. Sort this out ahead of time, it will save you a lot of hassle. You will be happier with your new acquisition if you can get to see it in action as soon as possible.

There are also a lot of car stereo amplifiers on the market, it pays to be aware of how the car stereo speaker you are considering compares to the others, and how compatible it is to your amplifier or the amplifier you’re planning to buy. Car stereo speakers and amplifiers go hand in hand. You’ll want the car stereo speakers you buy to be suitable for your automotive entertainment needs and not strain the system.

Style can be an important factor when choosing your special car stereo speakers. You’ll want the one you choose to fit in perfectly with your other all sorts of stereo speakers. If you’re planning to install something different, you have to take into consideration the modifications your going to have to make in order to accommodate your new car stereo speakers.

One of the biggest issues in buying a new type of car stereo speaker is suitability. How suitable your car stereo speakers are is probably the biggest issue. Don't forget the reason you’re buying the type of car stereo amplifier in the first place, and ensure that the all sorts of stereo speakers you are looking at will do the job you need no matter what other fancy features they may offer.

Brand is an important consideration when you are shopping for a car stereo speaker. The fact is, one brand of type of car stereo amplifier may have a much better reputation than another, and for good reason. You be the judge. Do your research. Ask car audio enthusiasts. Read magazines and reviews. Do you want to take a chance on just any car stereo speakers, or go for the proven name brand?

Lastly, price is important even if you think it's not. After all, would you want to pay more for your car stereo speakers only to find it cheaper the next day at a different store? Nobody likes that. When shopping for better car stereo speakers, it pays to check at least a couple of different stores, just to make sure you're getting your car stereo speakers at the best price.
