Logging the data received from the dynamometer

On old-fashioned dynamometers, the operator or the observer had to manually record the simultaneous readings on paper. Nowadays, most dynamometers replace the observer’s notes with computerized devices that acquire and store the data. Because of the very loud noise generated by the dynamometer and the engine, a performance test is stressful to anyone who’s watching it. In these given conditions, it is very difficult to manually record all the data. A reliable computerized data acquisition system is considered to be indispensable today among engine builders and testers. Nowadays it is possible to buy recording, control, and playback capabilities in a palm sized package, that many years ago would have cost a lot more and would have had the size of a refrigerator. An appropriate computerized data acquisition system must have a very fast sampling rate. For obtaining quality data, you will need at least 100 samples, of all sensor channels, per second (100Hz). A 200Hz logging rate or more is even better. It is important to remember that between spark plug firings there is a drop in torque and rpm that can be measured. The crankshaft is accelerated right after combustion occurs and afterwards it slows down until the plug will fire one more time. It is not possible to detect these rapid highs and lows when you are driving on the track or on the road, but the dynamometer will. Therefore, a 200 Hz logging rate for your data acquisition system should do the trick, as well as an appropriate dynamometer. However, if you sample at only 50Hz, you should consider that you are recording a single torque and rpm sample every other revolution. From time to time, a series of samples will synchronize with the firings of the plugs, and sometimes the data samples will fall in synch with some lower power compression strokes. If you are using a fast and reliable acquisition system that read each cycle multiple times, then the data captured can be used to average out the given phenomenon. Averaging the data is a very important step in data acquisition. At this point, while experienced dynamometer operators see an identical power curve in both graphs, inexperienced dyno operators expect to see a smooth, clear line. The reason why the ability to average and dampen the data is essential for the acquisition system is that you don’t have to deal with so many printings. For instance, at 100Hz you're getting 1000 lines of data for even a ten-second dynamometer pull. You might choose not to search for any small changes in dozens of pages of data every time you want to prepare another run. Averaging both eliminates transient noise and produces clear printouts, and thus it is very useful in the process of logging the data from the dynamometer.

Tips On Dealing With Auto Fraud

The auto industry and their dealers are rife with scams and fraud and the potential buyer needs to be armed with the knowledge of how these scams work and how to avoid them. There are many dealers that run reputable businesses and can get buyers into a vehicle without using fraudulent means, but there are always those individuals or companies that are looking for ways to take consumers for a ride. The state of California, San Diego and Los Angeles in southern California in particular, is home to many of these scam artists. Even smaller states like Oklahoma have their share of fraud cases and attorneys there are as busy as lawyers in the larger California market. If you are fortunate, you won't be a victim of one of these disreputable dealers, but it is wise to be aware of potential scams before you head to the dealer. Here are some tips on dealing with auto fraud. People with bad credit are often the victim of fraud at dealerships. They are easy prey, often due to the fact that they believe they cannot get financing. The worst offenses usually occur in the finance office, where the potential buyer often lets their guard down. One way to lessen the chance of being scammed is to show up with no trade and to have your financing done through your bank, with a bank draft in hand. One of the most common frauds committed by car dealers and one that attorneys see frequently brought to them is the advertising fee scam. Dealers slip into the contract an advertising fee. Often times the advertising fee is on the factory invoice. Dealers add in a second advertising "fee" which becomes pure profit for them. The way to avoid it is to simply ask that it be taken off the contract. If the dealer tells you that the factory doesn't charge them an advertising fee, have them show you the invoice. If there is no fee on the invoice, which is unlikely, it is okay for the dealer to charge between 1% and 3% of the Manufacturers Suggested Retail Price or MSRP for an advertising fee. If it does not appear on the invoice, then the fee is completely negotiable. If it does appear on the invoice, then that is a case of dealer cost and is not negotiable. If you feel you are the victim of auto fraud, the best way of dealing with it is to contact a lawyer and learn what your options and rights are. If you have a good case, a lawyer will have no problem presenting your grievance to the court.

Press Release: Why SEO Experts Should Not Use Press Releases

Rumor has it that press releases are the next big thing in the SEO business, and many companies are spending top dollars trying to write the next big press release announcing the next big balloon breaking technology. But is this really the next big thing? By definition, a Press Release is a kind of news item released by the company on whom the news is being reported. As such, you will have to compete with all the other press releases and hope that your will get picked up. Why Will Your Press Release Be Trashed? 1) Unless you are writing a press release about Microsoft, Adobe, Sony or one of the other mega-companies, or at least about a company that is relatively well known, forget about it. Journalists and news editors receive thousands of press releases a day and there is no way that they will waste more than a quick glance. So why should you pay a company seven to eight hundred dollars for them sending your press release to thousands of editors and journalists when they are going to junk it anyway? 2) Unless you are announcing a truly revolutionary product or technology (which I assume you are not since you are only interested in using the professionally paid and written press release to boost your search engine rankings), whatever you make up or announce such as some new free deal or new portal offering something unique, your chances of being picked up are very slim. Yes, the PR companies will tell you that they have vast experience in writing Press Releases that will make yours stand out and get picked up but this is not accurate. The only way your PR is going to get picked up is if it truly is something out of the ordinary or something that no one has ever thought off. 3) Unless you plan to spend millions of dollars and then just by sheer volume your site will go ahead in the search engines, this is not a good option. Why? If you send a large number of press releases then these will be placed on the different PR companies websites main page. Since most of these home pages have a very high page rank, your site will get a boost. The question is whether this boost is worth the large amount of money you will put into the PR companies pocket. No it is not. Use that money to buy (though I do not recommend this) links from high-ranked websites and you will pay less and receive more benefit. 4) Any press release, even if it has been accepted, will remain on the different pages for just a short time, making the time and effort and even more so the amount of money you paid fruitless. Conclusion: A press release is useful if you wish to contact the press and maybe get some free publicity, but it is of no use if you wish to use it as a tool in order to advance your website in the search engines.

Why Donate Your Car To Charity?

If you have an old car in your garage (or backyard) and you don’t have a clue how to get rid of it, one way is to donate your car to a charity. You might think that your old car won’t matter at all and it’s a piece of junk, but your car can still be useful. You will be helping a lot of people, and at the same time gain something for yourself. Car donation is the best option to get rid of an unused car while giving you the chance to help yourself and others. Your charitable donation might mean a lot, without you even realizing it. You can get started by finding a charitable institution online. It is best to search for them online because it is the easiest, fastest way to get the information you need. While online, you can speak to a representative and they will explain the steps and procedures and the law regarding tax deductions. If is important that you are aware of the tax deduction rules so that you’ll know what to expect regarding the benefits you’ll get from your donated car. If you donate your car, you can claim a tax deduction of up to $500. If the charity sells your vehicle for more than $500, you will be notified with the exact amount of the sale, and can use this amount on your tax return. The market value will depend upon the kind of vehicle you donate. Not all values are equal. For example, late model cars and vans that have seen a lot of miles can be used, though they might need some costly repairs before they are ready to be put back on the road by the charity. Donating your unused car to a charity is a great way for you to get a deduction on your taxes. Some of the organizations use the cars for their services and personal travel, while the others sell them directly to raise funds. You should also know that some programs aren’t run by charitable institutions, but rather salvage companies that use the name of the charity as a front, and in return they pay the charity a set amount for each of the vehicles donated. To make sure that you are dealing with a trustworthy charity, you should ask what they are planning to do with your vehicle. If they plan to sell your car, will they use a broker or not? You should also ask if the charity is receiving a large amount of the selling price, so that you know how much of the money will go directly to the cause you are trying to support. Your best choice is a charity that is collecting a percentage of the sales price, rather than the per-car flat fee.

You must understand now that the technology is presently online to insure that you can do business including the necessary exchange of sensitive information over the internet. So there is really no difference in security whether you choose to donate car off the lot or on the internet. What then are the advantages of choosing to donate car via the internet that supersede the risk of not being able to personally check the car and see it with your own two eyes? Well there is the amazingly powerful advantage of searching for the right charity which saves you time and therefore money and lots of it. There are also systems set up to on the internet reduce fraud and cheating that are not necessarily available when buying cars, especially from private donators. There are licenses that certify the credibility of the charity. There are also systems set up that hold charities accountable for misinformation, and it is now becoming more and more popular to offer receipts which official tax credit numbers.

Tips On Buying Warranty For Used Cars

Used car buyers need to get their money’s worth as soon as their purchase has been confirmed. New or not, cars should have warranties. It is a right, not a privilege. The following are tips to better your chances of getting the best warranty for your money. Know what you are buying Some people who avail themselves of auto warranty coverage usually have a notion that they are purchasing a special shield that protects their vehicle from unnecessary wear and tear. Though this is true, this idea is primarily bound to a contract that the buyer should read prior to signing anything. There are instances when consumers buy a used car then expect the warranty company to get their cars back in shape for them. Buyers then unnecessarily file a complaint and get angry once their request is denied simply because their understanding of the conditions that constitute the warranty differs from what the warranty company has explicitly stated on their contract. It is advisable therefore to read in order to avoid uncalled for weeping. See through the “lies.” Do not believe when auto warranty companies claim that their warranty can not be refunded. One hundred percent of extended car warranties are refundable within thirty days provided no claims have been made. If in any instance you feel that you were in some way forced to purchase or getl a Ford, Hyundai or Honda warranty that you didn’t want, do not hesitate to get your money back. Sift through their trashing If a warranty company has a good enough standing, it does not need to trash the competition or badmouth the other company’s warranty contract. You need to see them point out their own warranty company merits, offers and packages and not the competitor’s “worthless” clauses in order to make a sale. Though it is a competitive world out there, the only way to stand out is to offer excellent and ethical service. In this case, action speaks louder than words. Avoid buying auto warranty from you dealer Though it is extremely convenient to do so, the effects are short-term. The price car dealers’ offer for extended auto warranty, believe it or not, is usually two to three times higher than the normal rate. Plus, their contracts have far too many limitations and unfair clauses that buying warranties from first-rate warranty companies that provide better service for half the price, is a clearer and – should be - the only option.

Pros And Cons Of Used Car Classifieds

There are several options to buy used cars. Although choosing between these options would depend on your priority and preference, you have the benefit of sorting all the listings in classified ads. The majority of the used-car dealers provide their list of sales in classifieds. With so many options, how would you determine whose terms could provide you with the appropriate used car of your choice? Here is a list of second-hand car buying and selling options, and each of its pros and cons. 1) Dealers: They provide you with a guarantee of title and the best legal protection. They offer a broad selection of cars and most offer less expensive and older model cars. On the other hand, trade-ins could not provide the best price for your old car and purchasing of used-cars could be risky since most dealers buy from taxi companies, police departments and lease fleets. To ensure the quality of a second-hand car, visit a dealership that specializes in the makes and models you prefer. 2) Private Owners: There are two different sides of buying from a private owner – they maintain their car regularly or they are trying to sell the car to dispose of junk. Although most privately owned used cars come cheap, you would be taking a car-investment risk with no warranty, security title and no legal recourse if you purchased a lemon. You should ask for repair and maintenance receipts to ensure the upholding of the vehicle. 3) Car auctions: Here you could get a good deal and save a lot of money if you really know cars and are an avid fixer-upper. Auctions also guarantee the car title. However, you should first do your homework. Some auctions do not provide warranties, cannot let you run a test drive, and you will not be able to check the vehicle’s history record. 4) Rental car companies: Rental cars are a good deal since they are rented by vacationers, businesspersons for short trips, and are guaranteed wearing road trips. Their cars are regularly serviced and they could provide the records of maintenance history. However, even with a maintenance record, buyers would not have any idea who has driven the car before buying it. Rental cars could also cost slightly more than used-cars bought from private sellers. Research is important to guarantee a best deal in your car investment. Avoid being scammed in the classifieds by trying the best option that would suit your needs.
