Car’s Exhaust and Muffler Systems

One made a fast truck when they redesigned the new Tundra. The 5.7L V8 has 381 hp, making it a good truck for hauling and towing. But a lot of people will tell you that you should modify the factory exhaust system. You should only consider it after you’ve learned the facts.

Fortunately, the factory exhaust system is efficient and doesn’t require much modification. The new Tundra comes with a 4 into 2 into 1 exhaust manifold, which has been found to be most efficient for moving exhaust gases quickly. The exhaust manifold is also made out of stainless steel, which is light and resistant to rust. And, the exhaust manifold has equal length exhaust tubes making it as good as most products available after-market. In short, the exhaust manifolds on your new Tundra don’t require any modification.

Next we have the catalytic converters. These legally required emissions control devices are often accused of restricting a vehicle’s exhaust, but in the new Tundra that’s not the case. They are efficient and they benefit the environment, so they’re definitely off limits.

Once we get to the very back of the exhaust system, we come to the tail pipe. The tail pipe is where all the exhaust comes out. Depending on the state of the engine, exhaust can come out white, grey or even black. If it comes out black, then there is usually a problem with the engine and it should go in to be fixed.

The great thing about the exhaust and the muffler is that if something goes wrong, it is not too hard to fix it, especially the farther you get away from the engine. If your muffler falls off, you will need a new one, if it develops a hole, you will need to get it patched. Thankfully, all of this can be done at any Los Angeles repair shop as the repairs of exhaust systems are generally quite easy to do.

After the catalytic converters, the exhaust gases from each side of the motor cool somewhat and meet-up at the muffler. Again, the factory system is pretty good. You won’t see a significant hp and torque gain by replacing the factory muffler (3-5hp, 5-10ft-lbs at the most), but you will HEAR the truck better. The rumble that you’ll hear if you do this is intoxicating, but there are about a hundred different mufflers to choose from to help you get the rumble you want. TRD, Borla, Flowmaster, Gibson, Edelbrock, Magnaflow, etc all offer quality products. While brand is important, it’s more important to know what you want.

Stainless steel or aluminized steel — that’s what you’ll be asked when you’re choosing your new muffler. While stainless looks cooler, that’s not really a good reason to buy it. After all, how often is anyone going to be looking under your vehicle? The best reason to choose stainless is resistance to rust. If your local geography has salt water or high humidity, stainless steel is a good idea. Otherwise, save some coin and go with the less expensive galavanized or aluminized steel.

Mercedes Aftermarket Parts

Mercedes is known for setting rigid standards in car production, and its models have always been a showcase of precision engineering. However, there are instances when concessions have to be made in the production of certain auto parts. One of the reasons for this is the use of material-saving strategies, when a company decides that a car part has to be produced in the most cost effective way possible while meeting design requirements. These strategies are often employed in the manufacture of what appears, at first, to be trivial car components. More often than not, these components would prove critical to the operation of the vehicle. Then later on, due to their design limitations, vehicle performance is affected.

Compromise in the fabrication of some auto parts has led several vendors to make and sell Mercedes aftermarket parts. These parts are intended to replace the original equipment that comes with your Mercedes purchase in order to improve vehicle performance or to replace a damaged stock item at a lower price. While many aftermarket vendors operate independently from the original car manufacturer, some are licensed to create replacement parts. Auto parts that are made by the car manufacturer or by its licensees are called Original Equipment Manufacturer (OEM) parts. Since OEM parts are built according to the original specifications, they are sure to integrate seamlessly to the vehicle. If you want performance however, you can turn to vendors selling Mercedes aftermarket parts.

One of the most overlooked items in your Mercedes inventory is the exhaust manifold. With its collection of tubes, the exhaust manifold looks plain, doing a seemingly mundane function of channeling the exhaust gases from the engine to the exhaust system. Investigate further and you will be surprised to know about its role in engine life and performance. When the exhaust gases are not flowed out to the exhaust system properly, they collect on the passages of the exhaust manifold and create backpressure. This buildup of emissions forces the engine to exert more energy in getting rid of the exhaust gases that are still inside its chambers, resulting in power loss and internal wear. This could be prevented if only the exhaust manifold is made wider and longer to accommodate more exhaust. To solve this, vendors have created a Mercedes aftermarket part called header as replacement for the factory-installed exhaust manifold. Headers reduce backpressure by providing each cylinder with its own exhaust pipe, ensuring a smooth flow of exhaust.

Another Mercedes aftermarket part that has become popular with many car enthusiasts is the cold air intake system. If your Mercedes doesn’t have one, you are letting go of an extra 5-10 horsepower you can squeeze out of your engine. Stock air intake tubes have bends to fit inside the engine compartment that reduce noise when sucking air. As a result of this design compromise, oxygen is supplied poorly to the engine, causing poor fuel combustion. In order to preserve cold air intake performance, the cold air intake must be replaced with a wider one that has fewer bends to increase the volume of oxygen supply. Combined with a cooler air source, the system will allow the engine to breathe easier, creating more power, boosting throttle response, and improving fuel economy.

Understanding a marine exhaust system

Marine exhausts systems are an important and often overlooked for a marine engine. Most ships have a “wet” exhaust system. Salt water is injected into the riser – the outlet of the exhaust manifold exhaust. This mixture of exhaust gas, and water is then passed through a series of curves, until he left the boat, preferably at the rear.

exhaust mixed with salt water to create a highly corrosive mixture. This is why exhaust systems are generally improved by using non-corrosive components, such as nitrile rubber hose (brown – not green – stripe), galvanized steel, fiberglass or plastic. The purpose of these elements, which vary in size and shape depending on the engine size and format of the machine is hydraulicing to prevent the engine. This is due to a motor in salt water, which has more exhaust gas and can cause considerable damage and completed entry if left for more than two hours. Water enters the action of the shaft at the rear exhaust and emissions technology design. In certain oceanic conditions, as a sailor, water may again be forced to exhaust when the engine is not running. Poorly designed exhausts, the flow of water and fill the new water collection box / muffler and pipe into the exhaust manifold, exhaust valves and combustion chamber. With the engine full of water, the engine does not turn on the water can not compress.

You’ll know your engine is hydrauliced if they do not turn around – usually after a long period of navigation – and you have removed the starter and make sure it works. To remove water from inside the combustion chamber, first you injectors, crank engine blow on water, refit drain injectors, injection lines and run it. Then leave motor running until exhaust sorted.

Check that the riser is not coked grown or corrosion – a common problem. To check the exhaust riser, remove the exhaust pipe of the riser (often a difficult process) and look at the line, to see if limited build exhaust / salt. If excessive accumulation of the riser must be removed to check the end of the line engine. Coke can be removed, a correction in the short term, although often the riser must be replaced. There are alternative systems of varying quality. Make sure you match the proper application design.

Make sure that the water-lock is low enough and big enough to hold all the water in the exhaust system. Is there a gooseneck or central vertical loop in the hose to the output bar? Is there a siphon break and is working properly – no leaking valves?

Exhaust gas is poisonous and can cause motion sickness and headaches. Replace defective parts immediately. Use double hose clamps on each joint or, preferably, super clamps, bolt style, cement and air needed. Hot sections should be avoided with duct tape fiberglass burns to his bottom.

Beware of asbestos coatings. Many older ships and marine engines had exhaust systems that were lagged with asbestos tape and rope. Acoustic Asbestos was also common in more ships.

Performance of aftermarket exhaust

There are a few different areas of your exhaust system and each is very critical to making your car run. The first is the exhaust manifold. This is usually made out of aluminum, stainless steel, or cast iron. The system is responsible for air intake and is connected to the cylinder heads. They take each cylinder’s exhaust and combines it into one tube.

Going down the line we have the oxygen sensors. Most modern cars require you to have this little plug to measure the ratio of oxygen to harmful exhaust. The sensor takes that information and tells the car its reading, helping it to maximize power and fuel economy.

The next area of the exhaust is the catalytic converter. This contraption takes the harmful gases that are produced by the engine and makes them a bit less harmful. It is mounted between the exhaust manifold and the muffler, and some states require you to have one.

Next we have the cat back, which is located between the catalytic converter and the tail pipe. Most performance systems usually have a mandrel-bend in them that can streamline the exhaust exiting process, resulting in more power.

The muffler is the most famous part of the exhaust and it’s the one area that most people are familiar with. Your engine is very loud and it’s the mufflers job to quiet it down. Most use battles to bounce the exhaust around, reducing the energy and bringing the noise down a bit. Some will use fiberglass to quiet the engine.

Finally, we have the exhaust pipe. This is the final bit of the system and it’s usually made of stainless steel or aluminized steel. This helps the pipe last longer and it should be able to maintain a shine if you take care of your car.

Exhaust Manifold and Header

An exhaust manifold or header collects the exhaust gases from multiple cylinders into one pipe. Usually constructed of cast iron, the exhaust manifold is a pipe that conducts the exhaust gases from the combustion chambers to the exhaust pipe. It has smooth curves in it for improving the flow of exhaust. The exhaust manifold is bolted to the cylinder head, and has entrances for the air that is injected into it. It is usually located under the intake manifold. A header is a different type of manifold; it is made of separate equal-length tubes.

Investment casting

Investment casting is an industrial process based on and also called lost-wax casting, one of the oldest known metal-forming techniques. From 5,000 years ago, when beeswax formed the pattern, to today’s high-technology waxes, refractory materials and specialist alloys, the castings allow the production of components with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys. Lost foam casting is a modern form of investment casting that eliminates certain steps in the process.

The process is generally used for small castings, but has produced complete aircraft door frames,
steel castings of up to 300 kg and aluminium castings of up to 30 kg. It is generally more expensive per unit than die casting or sand casting but with lower equipment cost. It can produce complicated shapes that would be difficult or impossible with die casting, yet like that process, it requires little surface finishing and only minor machining.

Tobacco Water Pipes: The Unique Smoking Experience

If you like to smoke tobacco and you are sick of the traditional forms of smoking, then you obviously have never smoked out of a tobacco water pipe. A tobacco water pipe has a reservoir that you place water into. The bowl, the object you place the tobacco into, is attached to a stem that is then submerged into the water.

As you light the bowl with the tobacco, you inhale through the hole that is designated for your mouth and the tobacco is then filtered by the water as it flows into your lungs. This makes smoking safer than using a regular tobacco pipe and the experience is much more enjoyable, according to the many people who regularly enjoy smoking from tobacco water pipes.

Hookahs
For centuries, people have smoked from tobacco water pipes but they called these hookahs. Middle Eastern countries such as Iran, Saudi Arabia and Turkey are well known to use hookahs. These tobacco water pipes have long, ornately carved stems from which many hoses emerge. The idea is that when the bowl is lit, several people can enjoy the smoke at once. This makes the hookah a truly unique smoking experience, something enjoyed by several at once rather than being just a solitary activity.

Most hookahs are lavishly decorated and it’s not unusual to see gold and even jewels used in the decorated of the tobacco water pipe. In some countries, it’s seen as odd not to own one and the popularity of hookahs has even encouraged the opening of hookah lounges. These establishments sport several hookahs where customers can come to sample different flavors of tobacco. Sort of like a bar, it’s a bonding experience where many people can come and relax and smoke off the hookah.It is important to clean your tobacco water pipe regularly. If you don’t clean your tobacco water pipe, you could affect the taste of the tobacco you use and it can also hinder your experience in other ways, such as making you sick. Change the water regularly and make sure you use a pipe cleaner on the hoses as well as the stem. Keeping your tobacco water pipe clean is seen as etiquette, especially if other people will be smoking off it.

Tobacco water pipes can be made from different materials. There are glass water pipes, plastic and even metal. The different materials can be cleaned but you must be careful of the cleaning agents you use to prevent damaging your tobacco water pipe. It’s best to just use warm water if you can get away with it as certain chemicals can damage your tobacco water pipe and that would be a shame, especially if you owned a beautiful, elaborate hookah.

Owning a tobacco water pipe is a special thing, as many people can become attached to theirs. Once they smoke from their tobacco water pipe, they would rather not smoke out of anything else. If you like smoking, and you like pipes, get a tobacco water pipe and you’ll likely never stray again.

New Infusion Set

Pump maker Disetronic announced on May 29 that its new Ultraflex Soft infusion set is now available for all insulin-pump users.

The Ultraflex Soft has a reversible connector at the base that “clicks” into place. In addition, it has a cannula that is tapered for easier insertion.

“We built this product from the ground up, using patient input to create the right features,” says John Odegard, marketing manager for Disetronic. “The Ultraflex is different from the Quick-set and Sof-set because the reversible ‘click’ connection system is much easier for persons who are vision impaired or have neuropathy.”

Odegard says the Ultraflex disconnects easily at the base, has a flexible Teflon cannula and doesn’t need an insertion device. It also has a clear window at the top of the infusion set, which makes it “easy to view your insertion site.” Compared with the Sof-set, Odegard says the Ultraflex introducer needle is a smaller 27-gauge.

“The Sof-set has a 26-gauge needle, which extends four mm beyond the cannula,” he says.

The Ultraflex Soft has a 90-degree insertion angle, as well as a soft Teflon cannula, which can flex with the patient’s body tissue.

The universal connection feature is compatible with all insulin pumps on the market. The set come sin two cannula lengths and three tubing lengths to fit all body sizes and types.

Odegard says all infusion sets need to be changed approximately every three days

Foley Catheter Insertion

What Is It?

A Foley catheter is a thin bendable tube with a balloon on the end. The end of the tube and the balloon are pushed into your bladder to drain urine. While this tube is in the bladder, urine is drained from it right away. You may need this catheter for just a little while or for a long time. How long you need it depends on why you have it.

The bladder is a hollow organ that holds urine. When you are ready to pass urine, it travels through the urethra (a small tube) to an opening in the body. Urine is let out of the body through this opening.
Why do you need it? You may need a catheter because of an infection, or a swollen prostate gland. You may need a catheter because of medicine you are taking. You may need a catheter because of a disease or an injury that is

causing problems in your urinary tract. Catheters may be used because you cannot pass the urine by yourself. After surgery, some people need to have catheters. The catheter is often used to keep track of how much urine a person is passing. When you have a catheter, it is important that you drink enough liquid every day. Ask your caregiver how much liquid you should drink each day.

Inserting a Foley catheter:

You will need to lie on your back covered by a sheet. While wearing sterile gloves, your caregiver will carefully clean the area around your urethra.

A soft tube called a Foley catheter will be gently put into your urethra. The tube will pass through the urethra and into your bladder.

When the tube gets to your bladder, the balloon will be filled with sterile water by your caregiver. The balloon will keep the catheter in your bladder.

The balloon presses against the wall of your bladder. This may make you feel like you need to pass urine. Instead of you passing the urine, it will drain out the catheter and into the urine bag.

To keep the catheter in place, it will be taped to your abdomen (stomach) or leg.Putting in your catheter should take about 10 minutes.

Caring for your Foley or leg drainage bag:

Catheters are designed to be closed drainage systems. This means that the path from the tip of the catheter inserted into the bladder, to the bag which catches urine, is closed. A closed system decreases the chance of getting an infection. It also decreases the chance of the catheter breaking and urine spilling out. People with catheters and their caregivers should avoid detaching parts of the catheter along the closed system unless it is necessary.

Larger, sterile, drainable, 2 liter drainage bags or smaller sterile leg bags are used to collect your urine. To
keep a closed system, these bags are connected directly to the catheter. If you use a leg bag to collect urine, a larger drainage bag may be attached at night with a special connector. A drainage bag should be emptied only when it is full enough that this is needed. Some plastic drainage bags should be changed every 5 to 7 days. Ask your caregiver how often your drainage bag should be changed.

Drainage bags must be kept below the level of the bladder. This will allow gravity to help drain the urine, and will stop urine from flowing back into your bladder. Urine that flows back into your bladder increases your risk of an infection. Do not let the drainage bag rest on or touch the floor. The tubing that goes from your urethra to a leg bag should be secured to your thigh with special tape, a leg strap, or a drain tube stabilizer. Allow extra tubing between the urethra and the point where it is secured to your thigh.
CARE AGREEMENT:

You have the right to help plan your care. To help with this plan, you must learn about your health condition and how it may be treated. You can then discuss treatment options with your caregivers. Work with them to decide what care may be used to treat you. You always have the right to refuse treatment.

Definition of Oxygen mask

Oxygen mask: A mask that covers the mouth and nose, and is hooked up to an oxygen tank. It delivers oxygen directly to the patient. Oxygen can also be delivered directly through a nasal catheter, a tube that divides into two smaller tubes that go into the nostrils.

Oxygen is a colorless, odorless and tasteless gas that makes up about 20 percent of the air we breathe (and at least half the weight of the entire solid crust of the earth) and which combines with most of the other elements to form oxides. Oxygen is essential to human, animal and plant life.

The chemical symbol for the element oxygen is O. As a medicinal gas, oxygen contains not less than 99.0% by volume of O2.

Oxygen was discovered in 1774 by the British scientist Joseph Priestly but he did not name it “oxygen.” He called it dephlogisticated air. (Priestly discovered three other chemical compounds, one of which, nitrous oxide -”laughing gas” – is still used today as a mild anesthetic agent, as during dental procedures.)

The word “oxygen” came from the French “oxygene.” It was so named by the French scientist Antoine Lavoisier (1743-94) who thought it was a necessary ingredient in all acids. This is not so. Hydrochloric acid (HCl), for example, contains no oxygen.
