LED Technology In The Modern Automobile

I was reading an article in a motoring magazine on the dramatic development of the LED and the impact it is having on modern automotive design.

One of the topics of discussion was the wake up call it is giving to the automotive industry. One very influential demonstration was at a motor show that had the release of the Jaguar C-XF and while this would not be the first show car to have LED’s it was considered one of the most dramatic.

The debut was at the Frankfurt Motor Show and used LED’s to provide a very dramatic visual presentation. The display was kicked off by the press of the Jaguars start button.

First was an impressive display, some would say ‘explosion’, of blue lighting that began with the instrument panel, then flew around the cabin, combining after encompassing the rear seats. Along with this was a burst of more blue projecting itself down from the interior roof lining, at the same time the grille suddenly burst into life with a glow of LED lighting, very impressive.

And to finish the flash of feline impressions (well it is a Jaguar) the headlights had streaks of blue bisecting each of the rectangular elements.

Another leading example of LED technology in the automobile is the Audi R8. If you see one in the daytime you will notice daytime running lights under the main headlights, these are LED lamps. But don’t think it stops there as the Audi R8’s complete headlamp assembly, including the turn flashers, and the main and dipped beams are LED’s.

The LED first made its mark in the automobile at the rear of the automobile. The 3157 LED and its derivatives found favor with the engineers as brake lamps as they reach full intensity faster than the traditional incandescent bulb. They are now used in many car tail lamps.

And some companies have taken this to the next level. BMW has some that increase in brightness as greater pressure is applied to the brake pedal. Mercedes Benz have the brake lights pulsing rapidly when the automobile is braking heavily.

Technology is allowing today’s automobile manufacturers to provide many entertainment and other computer based systems that have the potential to load up the cars power supply. So any device that can assist in reducing the energy consumption has suddenly become very attractive.

This is one of the key drivers that has lifted the LED to the top of the automotive lighting wish list.

This energy saving is not the only driver as one of the other benefits is the life of the bulb. The LED’s will outlive the automobiles to which they have been fitted. The owner will never have to replace a light bulb again.

Some of the other benefits include the ability to ‘tune’ the light so that the light emitted is closer to daylight. Also for automotive designers the constraints on shapes disappear as they are extremely flexible in the shapes that can be achieved. Also the heat generated is a lot less so lightweight plastics hi strength plastics can be used.

Battery, Ignition and On-Board Diagnostics

To keep an automobile up and running, diagnostic procedures must be conducted on a regular basis. While most testing is done to ensure soundness of the engine, it is significant to examine the battery, ignition and on-board systems as well. Failure of any of these critical components leads to a complete vehicle breakdown and loss of valuable time and money.

Battery Diagnostics

Increasing complexity in automotive systems leads to rising demand for electrical power. In turn, this leads to greater demands on the battery of the vehicle. Regardless of the automobile being electric or dependent on an internal combustion engine, ensuring battery reliability is of utmost importance. This requires regular monitoring of battery diagnostics while the automobile is running.

Since a battery discharges even when not in active use, its health deteriorates over time. Battery diagnostics helps in identifying a depleted or faulty battery, thus avoiding a system breakdown.

The latest approach to conducting battery diagnostics is measuring its state of charge in terms of current-delivery capacity and its state of health in terms of the remaining percentage of battery life while the vehicle, with its various electrical loads, is in operation.

Ignition Diagnostics

A timing light is used to set the ignition timing of a vehicle. When it is attached to the ignition circuit while the engine is running, it identifies timing marks, thus enabling setting the timing of the ignition system.

To do this, the test probes of the timing light should be connected with the battery terminals in congruence with their polarities. When its trigger is pulled, the timing light releases a beam every time the sparkplug fires.

Traditional timings lights consist of two test probes, of which one is clamped to the battery ground and the other is inserted between the distributor cap and the sparkplug wire. The spark of the ignition itself powers these low-cost timing lights. Since they use a neon bulb, they are not very bright and are useful only in dimly lit utility areas. Since newer cars are composed of direct ignition systems, timing lights powered by direct current are preferred.

On-Board Diagnostics

Repair technicians may plug automotive scan tools into the on-board diagnostics (OBD) connector to access functions that give information on the condition of the various sub-systems in the vehicle. Mechanics rely on these tools to diagnose the specific error that causes a failure in the system.

Automotive scan tools may be handheld or PC-based. Handheld ones for consumers include simple fault code readers and reset tools. For professionals, these tools access advanced diagnostics and control units, set ECU parameters specific to the manufacturer or vehicle and facilitate diagnosis or tuning by performing real-time monitoring and graphing of engine parameters.

More advanced, PC-based automotive scan tools convert OBD-II signals into serial data compatible for display on standard personal computers. These automotive scan tools offer larger storage capacity, higher screen resolution and better flexibility than handheld ones.

Originally, testing tools were bulky and affordable only for very big garages. The last decade has seen increased portability and cost-effectiveness, putting them in reach of even the smallest automotive repair service.

Some Information About Automobile Engineering

Automotive engineering is the field of engineering that deals with the production, manufacture, design, research and development pertaining to vehicles such as cars, trucks, etc. The career field for this section of engineering is broken up into three broad categories, namely – production, development and manufacturing. The production field deals with the designing and testing of the engines, transmission related parts and other portions that will help to assure safety, reliability and performance. The development field deals with the coordination of the overall design and the setting of the specifications of various individual parts is done in this specialization category. The manufacturing of various parts as well as the final assembly of the entire machine is done in the manufacturing field.

There are two paths that you can take if you want to be an automotive engineer – mechanical engineering and automotive engineering technology. Since the result of both the courses is more or less the same the basic requirements for both the courses are not too different from each other. You are required to have a background of physics, chemistry and mathematics in your early academic career but, since automotive engineering does require computer usage in the form of Computer Assisted Design and Modeling you will have to incorporate computer courses in your educationally formative years.

If you are looking into the production field and want to be a production engineer then you will need to take up courses in BSc in automotive engineering technology. This degree will help you to work on the designing and testing of specific components and safety measures. The study course will give most importance to applied design and testing. The schools with the best records for this degree are the Ferris State University in Michigan and the Arizona State University. The schools are also known to give internship programs that allow you to learn while on the job.

Getting a BSc degree in mechanical engineering will provide you with work related to the broader dimensions in terms of the design and manufacture of automobiles. The basic courses will give due credence to physics, chemistry and mathematics as they are the backbone courses of any engineering degree. Apart from this the school will also provide courses in analysis, design and the theory of the engineering involved by means of extensive laboratory work. Along this path you will find that the specialization in this field will be quite limited at the undergraduate level. Aspirants for automotive engineering have been known to basically focus on the preparation for graduate school. At the Master’s level most courses are focused on the study of electrical and mechanical engineering aspects that are applicable to vehicles, the systems design and methods of analysis on an advanced level. The course generally takes approximately two years and in most universities like the one in Michigan the courses that are offered require about 30 semester hours of study time.

Things to Consider Before Buying Used Automotive Radiators

As per the observation made by the transportation department of the United States, you can make your driving safe and smooth on the road by frequent radiator checkup. In fact, radiator can be considered as one of the most important auto parts that play a major role for an effective cooling system. The cooling system of a car must function properly to avoid any kind of mechanical breakdown. Replacing or repairing radiator, aids in decreasing the danger of roadside accidents or failure.

Car radiator can be generally defined as a type of heat exchanger, which aids to chill the engine by transferring warm air from the hot coolant to the air blown where the hot air is blown out through a fan. It is the main feature of a car cooling system that permits the engine to perform fine by maintaining the right temperature. So, if the radiator of your car is not working properly, replacing them can always be considered as the best alternative. Checking and replacing the defective old radiator regularly can definitely enhance the life and performance of vehicle. However, if you are thinking of buying a new radiator then you must rethink, as going for a used radiator can be yet another alternative. In fact, over the past few years the concept of selecting used radiators has gained enormous popularity.

These days there are various online catalogs and stores that offer used radiators in varied styles and sizes. You can choose easily according to your requirement, but before ordering you must perform an adequate research. Although a used radiator can save your considerable money, but it’s more like a speculation, unless you can find out that the used radiator is in good condition. Thus, there are few things that you must look for prior to plunking down your hard-earned money.

The Automotive Stereo Systems

Dying to satisfy that craving for that boom bass but can’t make the budget? Can’t sleep ‘cuz of that new Clarion head unit? Look no further, you require to find that discount vehicle stereo to fulfill your automobile audio needs. Well, there’s probably only two instances where a require for a discount vehicle stereo will come in. These two instances always entail lack of a financial comfort zone (that’s why they call them discount automobile stereos).

First instance, you don’t have an audio method in your automobile, and you would like to install one. Following the premise they have above, you’re most probably a automobile owner who doesn’t have funds to spend on a new, top of the line method.

What to do: How do you receive a discount vehicle stereo? One way is to go to a vehicle stereo sale. Still, you must deal with store prices, they’re cheap, but not that cheap. Another is to scour the classifieds and buy and sell for used items. These are real discount automobile stereos, but you must have a sharp eye to recognize which is a nice deal and which is a swindle. Ask the seller how lots of years they had it, in what automobile. Inspect the automobile where it is installed. If it’s still installed on the automobile, give it a go. If it’s a head unit, or a speaker that isn’t installed, be careful. Research the model of the discount automobile stereo you’re planning to buy, also find reviews.

Second instance: You already have a car stereo method installed, but you would like to upgrade it. Again, most probably you’re searching for a discount car stereo/discount automobile stereo method not far from what you have. Perhaps something with higher wattage, or a head unit which can play mp3s? And again, try searching at sales. Take advantage of classifieds, buy and sells, second hands, and also swaps. Chances are, if you’re a automobile audio enthusiast, someone in your circle currently has a better method than yours and perhaps willing to sell it to you. No require for standard pricing here. Or if others have equivalent items which they might be willing to swap, like a head unit for an amplifier, or a nice set of tweeters for a cd alterer (i highly doubt it) or your pedigreed pitbull for the whole shebang! You’ll get more discount automobile stereos if you have a circle of friends/people who share the same interest.

Discount automobile stereos are always a nice deal, you must know where to get one.

Other tips which might help: Another way to receive a discount automobile stereo is to SUBSTITUTE. Like cars, Japanese made units are often cheaper than German/European/American made units. Also, look at the basics. What is it that you require, as in the most BASIC FEATURES? Do you require that mesmerizing LED display, or can you do without it? Goes for speakers. If you’re not going to enter a automobile audio competition and you require to listen to nice treble and bass levels without making your speakers croak, perhaps you can do away with a couple of 3way/4 way speakers. A gigantic subwoofer will definitely require an amplifier, and those are already 2 things to buy.

Even if you’re not a automobile audio connoisseur, it’s easy to be impressed with a automobile 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 gigantic throbbing concaves blaring brilliantly low bass lines or icy small tweeters whistling out seething treble sounds.

Automobile stereo speakers are interesting and very tempting to buy, the gigantic loud ones. But gigantic is not always the best. Each speaker has its own distinctive quality, intended use and price range. Some may also be better than others at positive things so it pays to inquire in to your type of automobile stereo amplifier or head unit before you finally pick on a automobile stereo speaker for your method. Here are some features to think about:

Automobile Stereo Speakers

There’s as well as a lot of automobile stereo amplifiers on the market, it pays to be aware of how the automobile stereo speaker you are thinking about compares to the others, and how compatible it is to your amplifier or the amplifier you’re planning to buy. Those speakers and amplifiers go hand in hand. You’ll require the vehicle speakers you buy to be suitable for your vehicle entertainment needs and not strain the method.

These speakers are not all the same size and wattage, and this can cause a problem one times you try to hook it up in your automobile. Know the specs of your method. 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.

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

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

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

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

Automotive Damages From Rainwater

Although it is a common weather feature for most of the United States, rainfall can affect car performance, ranging from brake damages to fuel efficiency. Knowing and understanding the mechanical limitations and qualities of your vehicle can help you stay safe when the weather turns for the worse. In addition to understanding what kinds of damages can occur or what sort of conditions the parts of the vehicle can go through, knowing whether or not that vehicle will return to normal functioning can provide peace of mind in any questionable rainfall scenario.

The brakes on a vehicle are, perhaps, the greatest concern for a driver. Brakes can easily become affected by rainstorms, as brakes can soak up water. Whether driving through a storm or through a deep puddle, drivers should pay extra caution to their brakes when in wet conditions. Normally, the water trapped in the brakes can be removed by normal use, but slipping can still occur for a short time after they begin to dry. In most situations, there is no long-term damage. However, if problems persist, there may have been other damages done to the vehicle than just the brakes.

Fuel economy suffers in rainstorms as well, as the texture of a rain-covered car is less aerodynamic and the additional weight can affect performance over long distances. While these may seem like slight changes, some travelers attest to losing over five miles per gallon on lengthy trips, which can eventually cost anyone a significant sum. Additionally, the cooler air associated with rainfall makes the car’s combustion process more difficult, which can help explain a loss in fuel economy.

Among these problems, significant rainwater can cause body damages, and, if a flood develops, can ruin a car. If you would like to learn more about how defective parts can fail, and what you can do if this does happen, contact an auto defect lawyer.
