Pressure Ratio Made Simple

By Darnell Austria

If you're riding a Harley-Davidson motorcycle you must know it's driven from the twin cylinder, reciprocating piston, internal fusion motor unit. Reciprocating pistons means the pistons go up and down, or back and forth, or laterally depending on motor unit configuration.

Numerous aspects determine the operation of the motor unit however, one of the most basic is the compression rate of the cylinder/piston/head fitting. The greater the compression ratio is, the greater bang or force for each cylinder, up to a point.

A reciprocating piston motor generates hp by combusting a mix of air and gasoline to drive the piston inside the cylinder. This straight line thrust is known as the power stroke. The straight-line movement of the connecting rod-piston set up is utilized in the flywheel, which usually converts the linear motion to circular action. This rounded movement is then sent to the transmission, and also on to the backside wheel, creating forward motion. Sounds very simple, but actually is a lot more complicated.

The pistons in the Harley-Davidson V-twin are designed to deliver a unique compression ratio in a specified use for optimum operating efficiency. Past experiences and history have conditioned Harley-Davidson designers the best compression ratios for motorbikes cruised on the street.

To simplify factors let's make use of a single cylinder motor as one example. The average four-stroke single cylinder motor (one half of a twin cylinder motor) operates in a number of distinct phases. That's why it is named a 4-cycle motor (or engine). Through the intake stroke (1), air or gasoline is taken in by vacuum pressure throughout the exposed intake valve as the piston moves down. As the piston starts back up (2) the intake valve shuts and then the air and gasoline mix is compressed. Since the piston reaches up to the top of the stroke the air/fuel mix is heated by the spark plug then the piston is pushed downward violently by the expanding air and gasoline combination (3), producing the previously mentioned straight line action that is transformed via the flywheel into circular energy. As the piston comes back upwards (4), it drives the burned mixture released (exhaust gases). which is called the exhaust stroke.

lf the compression rate is decreased, the motor makes minimal hp. lf the compression ratio is comparatively high the motor can produce a whole lot more power for each cubic inch of displacement than an identical motor using a reduced compression setting ratio. A lot of things influence the cabability to operate a motor with higher compression, not to mention the availability of high octane fuel. With no supply of high octane gasoline, a high compression motor unit may be afflicted by pre ignition (pinging), due to the fuel air mixture firing ahead of time. Pre ignition is often very harmful for a motor.

Compression rate is defined plainly as being the volume above the piston at bottom-dead-center (BDC), divided by the volume above the piston at top-dead-center (TDC). The greater pressurised the fuel and air mixture is when burned the bigger the punch. A stronger force translates to much more power, as well as additional force on all of the physical pieces involved. High compression motors require the usage of high-octane fuel to avoid pre-ignition and/or detonation, which may cause expensive harm on piston rings, pistons and valves or possibly even worse, losing the race.

For average driving a lot of trained technicians suggest a compression ratio somewhere in 8.5:1 and 9.5:1. Any higher and a higher octane fuel qualification is necessary. With compression ratios lower than 7:1 a bike's motor simply cannot perform effectively. Hopefully you now realize what compression rate means. Then again, this is simply static compression rate. Cam lift and valve overlap and various factors decide the exact or functional compression ratio. Also, remember that increased compression ratios while boosting power may also increase deterioration of the motor. High compression motors usually are not good commuter motors, just like lower compression motors are not excellent racing bikes.

Bead Craft - Tools Of The Trade: The Finest Tools Which Are Essential To Improve Your Experience

By Jake Chambers

A topic not much discussed in articles concerning bead craft is what I like to all "optional equipment." Reasonably, most articles on beadwork concentrate on the beading projects, or the beads themselves and many discussions revolving around patterning, color selection and so on, but at least some concentration must be given to the optional items of equipment, because they can make your life simpler and enhance your enjoyment of bead craft in general.

The items I have in mind are:

Fishing Line

Magnifying Glasses

Cord Knotter

Bead Tray

I will outline what all of these can do for you as it relates to bead craft below.

Fishing Line - If you are all out of silk thread and requiring to crank out a bead craft project, simple fishing line can be subbed in for the good stuff. Or, if you are only making a temporary piece and want to save your silk thread for permanent creations, yet again, fishing line to the rescue! No bead craft toolkit could be without it!

Magnifying Glasses - This handy item will save you both time (reducing the time spent turning your beadwork into reality), and prevent eyestrain by bringing those very small, little pieces-parts into better focus. What's not to like about that! If you just get one piece of optional bead craft equipment, get it!

Cord Knotter - At around 10 bucks, this handy little item is the most expensive of the "optional bead craft equipment," but well value the money, particularly if you do any work at all with pearls. It assists with knot tying, and helps you get the knots right up against the beads, where you wish them to be (this can be a frustrating process when attempting to get it right by hand). It might take a lttle bit to get the hang of using it, but once you do, you'll wonder how you and your bead craft projects got along without it!

Bead Tray - Amusing how something as simple as a tray can make this type of large difference to your bead craft projects, but it truly can! The major benefit of a bead tray is that it is included with grooves for holding beads and the grooves are of ordinary shapes and sizes! So, when you're making a necklace, simply play with your pattern on the bead tray, get it just how you want it, and then all of your beads are already laid out in the exact pattern. Simply pick 'em up and string!

Again, while none of the items mentioned here are very essential, you'll possibly discover that you enjoy bead craft a good deal more with these time saving tools, and you can pick up the full set for around $25. A small investment really for what they can do to enhance your bead craft experience, and the ways in which they can assist you execute against your beadwork!

The Impact Of Home Theater Systems On The Home TV Watching Experience

By Sami Hamza

Since home theater systems appeared in electronic stores throughout the world, they have never looked back. Because of their popularity, more and more people want to experience what a home system can offer them. Now, there are many different types of home theater systems available in the market. Owing to the technological advancements that are now enjoyed in home theater systems, the impact on how people experience their TV has certainly increased.

There are some drawbacks with a home theater system, however. The reason for this is that home theater systems, like every other product, have both pros and cons.

A home theater system certainly allows a person to enjoy the ultimate TV watching experience. A good example of this is the fact that the majority of people that own such systems see a reduction in the time they spend in cinemas and sports fields. In fact, if set up properly, a home theater system can easily mimic the experience of watching a movie on the big screen or watching a match from the stands.

Moreover, there are many new options available to users because of the advancements in home theater technologies. For example, the majority of home theater systems found in the world today offer sound modification options. The Samsung Home Theater HT-E5500W is a good example of such features. The custom equalizer feature in this system allows people to manipulate the sound output to suit various situations.

There are other devices such as the multiple listening modes of the Onkyo HT-S3500 Receiver, while the YPAO system of the Yamaha RX-V373 Receiver allows the device to sense the acoustics of the room before modifying the sound output. What these types of features mean is that a user can simply modify his system's sound to cope with poor sound quality in the actual signal or even poor acoustics in his room.



While the advantages of home theater systems are considerable, there are still some disadvantages that can actually sour the entire home TV watching experience. A person must understand that the home theater system is designed to offer an overly grand experience.

This results in the speech quality suffering at lower volumes. This is evident in both the Samsung HT-E5500W Theater and the Onkyo HT-S3500 Receiver. However, this is a very small problem that can be dealt with by adjusting the equalizer to sort out the speech clarity.

The fact that home theater systems are difficult to install does not bode well for someone who does not have technological experience. The Yamaha RX-V373 Receiver can be taken as ideal proof of this. This system can be quite difficult to install which creates further problems for the user. Essentially, this means that the system's installation process is so complicated that it takes a considerable amount of time for the user to even realize that he has made a mistake.

Different home theater systems have different benefits and flaws, even though the majority of these advantages and disadvantages overlap. The reason for this is simply that while one manufacturer focuses on fixing one flaw, another emphasizes another flaw while leaving the first one alone and untouched.

What Powder Coating Is About

By Alicia Hunter

Almost every product with the exception of food and beverages would always be applied with paint. This is done in order to give the product a good finish so it will look good. Another purpose that paint has it to protect the item from deterioration. These days, manufacturers make use of different methods to apply paint. One of the most popular method being used these days is powdercoating Montgomery AL.

The method of powder coating an object is done by using a dry powder instead of the usual liquid paint. Powder coating is usually what manufacturers use for painting metallic objects since powder can adhere more to the surface. To do this, the surface will be pre treated to prepare it for the process. Dry powder will then be electrostatically applied. It is necessary to bake the object to harden the skin.

Powder coating can be done in two ways. For some manufacturers, they prefer to use thermosets. Others would use thermoplastics when applying the powder. There are also different kinds of polymers that are used for the process. Some common examples are polyurethane, polyester, acrylic, and straight epoxy.

You can now find a lot of industries that rely on powder coating for the application of paint on their products. This is very useful for those working in agriculture, automotive, airline, electronics, defense, and various transport industries. What these industries have in common is that they are always going to use metal.

One of the best things about powder coating is that it can produce a covering or paint that is very durable. The coating is so tough that pressure or force cannot easily chip or peel it off. This is one of the reasons why objects that have been powder coated are the kind that are always exposed to wear and tear.

Another advantage of using powder coating is that it is not very harmful to the environment. It does not contain any volatile organic compounds. This also allows manufacturers to recycle the overspray for the next painting session. This will help minimize the waste that the process can produce because it encourages recycling.

Powder coating is also something that can be done in ones garage provided that he has the needed items. To do this you would need your dry powder, an oven, and a powder coating gun. You can use the oven that is solely used for powder coating. If you do not have one, your toaster or conventional oven will do as long as you will not be using it for cooking.

Those who are too busy and do not have the needed items have another option. They can look for professionals who offer this type of service. These services are of great help to many homeowners and also for those people who have a small business.

Powdercoating Montgomery AL can be for commercial or for personal use. There are so many items that you can paint using this method. If you want to make the object durable and presentable, this would be the best method that you can use to paint it.
