A conventional marine diesel engine produces its power by hot compressed air igniting fuel which has been sprayed under very high pressure into the cylinder head. A marine diesel engine does not have spark plugs to ignite the mixture or a carburetor to mix fuel and air. Instead it uses the pistons to compress the air to 3000 kPa which causes it to become very hot and the fuel is ignited as soon as it is injected into the cylinder.

Some marine diesel engines are fitted with a heater plug in the inlet manifold or a glow plug in the pre-combustion chamber of each cylinder. These can provide additional heat to the combustion air during the starting process.

Diesel engines are heavier and slower revving than gasoline engines but they are also more reliable because they do not rely on external carburetion or an electrical spark for ignition.

Newer engines use an electronic fuel injection system whereby air and fuel are mixed thoroughly in the pre-combustion chamber before entering the cylinder. This system maximizes fuel and power economy and is also less polluting.

All skippers should understand how their engine works so let’s start with an explanation of the mechanical cycles.

Most reciprocating piston internal combustion engines work on one of two mechanical cyclesóeither the four-stroke cycle or the two-stroke cycle. These cycles list, in the correct order, the mechanical actions by which the fuel and air gain access to the engine cylinder, the gas pressure – due to combustion – is converted into power and, lastly, the burnt gas is expelled from the engine cylinder.

The Basic Four-Stroke Diesel Engine

From its name, it is obvious there are four strokes in one complete engine cycle. A stroke is the movement of the piston through the full length of the cylinder and, since one such movement causes the crankshaft to rotate half a turn, it follows that there are two crankshaft revolutions in one complete engine cycle.

The four strokes in the order they occur are:

1. Inlet stroke. With the inlet valve open and the exhaust valve closed, the piston moves from top dead center (TDC) to bottom dead center (BDC), which creates a low-pressure area in the cylinder. Clean, filtered air rushes through the opened inlet valve to relieve this low-pressure area, and the cylinder is filled with air.

2. Compression stroke. With both valves closed, the piston moves from BDC to TDC, compressing the air. During the course of this stroke the air becomes heated to a temperature high enough to ignite the fuel.

3. Power stroke. At around TDC, the fuel is injected, or sprayed, into the hot, compressed air, where it ignites, burns and expands. Both valves remain closed, and the pressure acts on the piston crown, forcing it down the cylinder from TDC to BDC.

4. Exhaust stroke. At approximately BDC the exhaust valve opens and the piston starts to move from BDC to TDC, driving the burnt gas out of the cylinder through the open exhaust valve.

The Two-Stroke Diesel Engine

The two-stroke engine uses two piston strokes to complete one power stroke and, therefore, it fires twice as often as a four-stroke engine. A two-stroke engine is smaller and simpler with fewer moving parts. A two-stroke engine has the potential to produce twice as much power as a four-stroke engine of the same size, however, because of the extra fitting required in a two-stroke diesel engine, for example blowers and governors, they become more expensive to produce. Recently there has been a move towards four stroke diesel engines which have become more efficient and smaller.

Protect Your Marine Diesel Engine

Protect your engine by avoiding long periods (more than 10 minutes) of idling in a ìno-loadî situation. This is often done to charge batteries or cool refrigeration but if done repeatedly it will glaze the bores of the engine and cause premature engine failure. If the boat is berthed the engine can be put in gear to create load at idle.

Today, almost every household has at least one laptop computer and with the designs now being small, portable, and convenient, yet highly efficient, it only makes sense that a laptop would be chosen over a standard desktop unit.  Sure, the market has many different laptop brands to consider but people who want the best of the best, there is only one – the HP Pavilion laptop computer.

HP or Hewlett Packard is one of the most longstanding and reputable computer companies in the world. They sell printers, computers, laptops, digital cameras, servers, networking, software and much more. All of the items they retail are of top quality and up to date in terms of technology.

Okay, so why should a consumer buy an HP Pavilion laptop computer over another brand?

There are actually a few different reasons as to why you would want to choose an HP Pavilion laptop computer. For one, you get a lot of variety. Whereas with some other brands you are somewhat limited to your options, with HP you can find the exact type of laptop you are looking for, regardless of your particular wants or needs.

In fact, purchasing an HP Pavilion laptop computer is an easy decision, ensuring you get exactly what you want and need, all rolled up in one system.

Sure, you have a choice of many options but there are a few laptops that rate higher than others do.  One in particular is the Pavilion dv9500tv series, which is ideal for consumers that want a robust system.  For people who want entertainment capability, this innovative system is unique, actually offering a fingerprint reader.
The power of this HP Pavilion laptop computer is incredible, and it features the Intel Core Duo and 64-bit New Core 2 Duo processors. It is able to run multiple multimedia applications in parallel but without slowing the system, which is quite a feat in itself.

Of course, this is just one option to consider, another the HP Pavilion tx1000z series.  This computer option is extremely portable, lightweight, and cost-effective but also very powerful.  One of the primary features is the display, which can be opened for everyday use or if needed, the display can be twisted to view files and movies in small spaces such as an airplane.

The high definition display allows you to see your images in crystal clear high picture quality, and the computer is equipped with powerful AMD Turion 64×2 dual-core processors with Hyper-Transport technology.

Just remember, no matter the HP Pavilion laptop computer you decide to buy, you know it is backed by the HP reputation and service, the most important of all considerations.  With so many incredible options, you will find you have multiple choices of the perfect laptop, one that will do what you need it to do while fitting into your budget.

One of the great things about modern cable and satellite TV is all of the sports programming now available to subscribers across the country. While 15 years ago you might find a couple of college football games on Saturday and a game or two on Sunday, today you can literally pick from two dozen or more games every weekend. Even the NCAA Men’s tournament has additional coverage with the Mega March Madness on Direct TV.

Content is king today, and as the saying goes the sports networks want to deliver as much content as possible to the viewer so they can make more money on ads. Lots of brand new all-sports channels have popped up in the last few years. Some of these include Altitude Sports, which carries Denver Nuggets and Colorado Avalanche matches, as well as the Big 10 network and the mtn, the broadcast home of the Mountain West conference.

Sure these channels are great for people in certain parts of the nation, but disagreements between the providers of sports programming and those who deliver the content have brought trouble at times to the customer. For example, the Big Ten Network began broadcasting in 2007, but they were in a carraige dispute with cable TV provider Time Warner. Customers of Time Warner in Wisconsin were not able to see some of the home town teams play due to this dispute. Finally however, the companies involved came to an agreement before the 2008 season, so subscribers could remain with with Time Warner instead of having to switch to one of the satellite television companies such as DISH Network or Direct TV. An important thing to do when considering providers is to consider all factors, comparing DIRECTV against Time Warner.

Out of market sports programming arrts bundles though are more friendly to subscribers, such as the National Hockey League Center Ice and the NBA League Pass, which are available on almost every cable TV and satellite company. DIRECTV seems to have all of the premium sports packages like the NFL Sunday Ticket.e another consideration for the customer. Some Dish Network customers have switched providers because the NFL Sunday ticket is exlusively with DirecTV. Many customers of large companies like Comcast are upset too, not understanding why a package like NFL Sunday Ticket isn’t available to them. Alternative spo

Read on to discover more about anxiety panic attack symptoms and causes and how to control them more effectively.

If you are a sufferer of anxiety panic attacks, it is important that you understand exactly what they are and how they happen. An attack begins when stress and anxiety levels increase to a degree where they are unmanageable by the individual who is going through the episode. The person will rapidly fall into a state of panic and fearfulness of surroundings, feeling that they are dying or having a heart attack and even going insane. In effect, the brain is saying to the body that it is experiencing a discomfort that is in all likelihood not real. Depending on the severeness of the attack, they can last anywhere up to about fifteen minutes. The experience often causes a vicious cycle where the individual dreads another attack, which just causes the symptoms to worsen.

Experiencing an anxiety panic attack can send anybody into delirium, and folks with anxiety disorders realize only too well how crippling they are. Instead of living your life in fear you can learn how to control them. Anxiety panic attacks usually come on unexpectedly to most folk, but what if there was some manner you could recognize the physical symptoms of stress and anxiety attacks. There are particular patterns or triggers present when an individual is about to have an attack. If you recognize these, then you could learn to prevent them. If you find yourself having an attack, then the best thing to do is to make yourself stress free and begin speaking aloud in a positive fashion.

You can take anxiety coping strategies to the next level in order to get rid of your panic attacks. You can begin by teaching yourself relaxation exercises. You will want to opt for something that is appropriate for you. Some of the more popular options are listening to relaxing music, reading and employing yoga. Once you understand what an anxiety panic attack is and what to do to control them, your life should be on the road to recovery. Anxiety disorders can make life complex but with a clear head and a lot of determination you should be able to manage whatever they throw your way.

Parents never know when the right time is to call a doctor for their infant.  They don’t want to call too early because they are afraid that they might seem overprotective or paranoid. However, if they call too late, they might seem uncaring and neglectful. As a result, parents feel a heightened sense of apprehension when their infant gets sick, especially for the first time.

The initial thing that all new parents need to know is that babies do get sick, similar to kids of any age group. A sick baby does not mean you are a bad parent. In fact, getting a small cold once in a while helps your baby’s developing immune system become stronger. How ever any cold or other sickness can turn into a difficult situation if not maintained under control.

When your baby sickens, try to maintain a normal feeding schedule. There is no problem with breast feeding your sick baby. In fact, breast feeding frequently might help your baby get better faster. If you baby is older and is no longer nursing, consider increasing her fluid intake, encouraging your baby to drink water and pure fruit juices.

Always call your doctor if your baby is showing signs of an emergency situation. Emergencies are wounds that will not stop bleeding or appear extremely deep. Any type of poisoning or possibility of poisoning means a call to the doctor. If your baby has a seizure or becomes unresponsive, call the doctor immediately.

Very often a fever is the initial sign you get when you baby is sick. If the fever is above 102 in a baby, you should call the doctor. A higher fever does not mean your baby is necessarily dangerously sick, but your baby’s doctor should know, so that he can advise you on treatment. Another indication that your baby needs to be seen is a sudden, drastic change in appetite. A good rule of thumb is if your baby skips two meals in a row, they need to go to the pediatrician.

Assessing your baby’s mood is another way to determine if they are sick enough to go to the doctor. Of course, a sick baby is not going to be her normal joyful self, but if your baby becomes completely inconsolable, call the doctor. When a baby crys for more than three hours that is a good sign that there is something more serious that is wrong.

Diarrhea that lasts for six or more diapers in a row is a sign of illness, and can lead to dehydration. The same goes for vomiting. It is important to know the difference between vomiting and spitting up. Most babies will spit up, and sometimes they spit up quite a lot of substance, but vomit will be forceful and projectile. As with diarrhea, excessive vomiting can lead to dehydration.

Above all, if you feel like something is wrong, call the doctor. Pediatricians are used to dealing with parents who do not know for sure how sick their babies are. They would prefer that you seek treatment for what turns out to be a small cold than ignore a serious illness. Keep your child’s best interests at heart, and do not be afraid to call the doctor when you suspect that something could be amiss.

Jerky made at Home

History has proven that beef jerky is one of the most popular foods made by our ancestors. There have been new methods like freezing chemicals.

People still love the tatse and ease of beef jerky original which is generally made from beef but has been recently enhanced by other flavours like camel.

Because when making jerky, all the fat and moisture has to be removed, jerky is in general a very good source of protein. Unfortunately many times these great benefits are offset by the chemicals added by some companies.

For Making your own health jerky follow these steps

1. Select your meat, lean beef is best it will save you time, scotch, round, sirloin.

2. Cutting the beef into strips less than 3.2 mm thick (1/8 ich) will give you the best results

3. To make slicing easy partly freeze your meat and slice at that temperature.

4. Make sure you trim all the fat because this does not freeze and can turn bad.

5. The type of marinade needed is made from sea salt and vinegar but you can use whatever you want. It needs to be put in the fridge to absorb the flavours, up to 24 hours.

6. Coatting the meat with flavouring of your choice ( unfortuneately sometimes this does make it sticky) try different things and see which results you like.

7. The meat needs to dehydrate this is done by leaving gaps between the slices . When dehydrators are used you need non stick spray on racks. When using ovens set them at 70 c allow them to preheat. Always keep in mind that the goal is dehydration not cooking.

8. The next step is watching most times this take 7 to 13 hours, check your jerky regularly until its consistency is what you are looking for.

9. When finnished Put your jerky in bags and keep it in either a fridge or a freezer until eating.

Home made beef jerky needs to be eaten a week after it is made. You now have a choice with the newer Jerky companies because many of these use traditional methods of manuafacturer and you can save your time.

If it looks too good to be true, well, it is. Don’t invest too much money in something that is not a safe bet, but don’t dream small when you can dream big.

This main thing you need to note is that whatever amount of money you have, you can make it work hard for you. If you do have some extra money today, invest it. If you have loads of investment money, there are plenty of chance for you to invest. You can invest in real estate, the stock market, or any other growth industry.In multiple streams of income, you do not identify yourself with one particular job. The main objective of working for most of us is to achieve success and financial freedom.

In the midst of all the alternative medicine treatments that you’ve heard about recently, you may have noticed aromatherapy mentioned a few times. Many dismiss the idea of using scents to bring medical results as quackery, and that’s understandable in many ways. There’s quite a bit of information about aromatherapy that comes from people who speak about it based on their spiritual beliefs and a lack of information that comes from detailed medical studies. As a medical treatment in Western nations, it’s still a little new, so there’s still much to learn about it. Let’s explore some of the ways that aromatherapy does aid people so you know how to better incorporate it into your life.

As A Medical Practice

The basis of aromatherapy comes from the use of essential oils, which are extracted from plants using distilling processes, resulting in concentrated liquids that are often very fragrant. In France, where aromatherapy is used in concert with traditional medical practices, but it’s for the antiseptic properties of the essential oils more than anything. In France, essential oils are sometimes prescribed and administered by a physician to target harmful organisms that might lead to bacterial, viral, or fungal infections.

If you’re wondering where the “aroma” part of aromatherapy comes in, there are traditional medical practices in the United States in which the scents of various compounds result in an alleviation of symptoms of illness. The approach most people are familiar with is the use of things such as Vicks VapoRub or Halls cough drops to help drain clogged sinuses and throats. Aromatic chemicals such as menthol and eucalyptus bring an alleviation of those symptoms, which are often associated with colds.

As Stress Therapy

When you begin to venture out of such applications and begin to talk about alleviating stress with aromatherapy, then you start to get into ideas that come less from observed scientific evidence than from everyday theories. Aromatherapy is often suggested as a way to reduce symptoms of stress in people and for other effects. For instance, basil oil is quite frequently suggested to ease the effects of depression and to help you to concentrate, while lavender is used for relaxation.

While many of these supposed effects aren’t determined through scientific study, it’s easy enough to notice that pleasant scents can make people feel cheerier. With that in mind, it wouldn’t hurt to practice a little aromatherapy at home; at best, it really will help and at worst, you still end up surrounded by nice scents. So, whether you’re using it for medical purposes or just to relax, aromatherapy offers something for you.

To help people find their way around today’s technology has invented the gps system. This is alternatively called a Global Positioning Satellite system. The gps systems use the satellites which have been made to help with navigation, tracking and location coordinates. You are able to purchase various items which have included a gps system. You should be able to find some low cost gps devices as there is a big range nowadays.

This however means that you will need to see about the various features that are present in these devices. With a gps system you should be able to see the monitor interface clearly. Your new cheap gps interface should be able to provide you with easy to see clear maps. Also to change from one feature or section of the map to another the touch screen should be in excellent working condition.

The different gps systems will also have varying prices which are also dependent on the features which are embedded into the system. For the most part you should be able to find a cheap gps within the price range of about $100 to $400 USD. Now just in case you feel that this price range is very expensive you might want to reconsider that thought.

The newer gps systems which have many new and improved features come in the price bracket of $999.99 plus. At the high end of the cost scale you can even find gps systems up to – you may need to sit for this – $2,000.00 USD. When comparing prices, paying $200 is a better option that paying an expensive cost of $2,000.00.

We can move ahead as soon as you have recovered from shock on this point. You will need to do some shopping and choose the cheap gps model which has all of the features that are necessary for a gps. These features should be a low price, an excellent quality touch screen monitor, a visible and easy to read interface.

The street maps should also be clearly visible. Even if it is dark you can see them as the route and your actual location are highlighted. The various street names, railway crossings, hospitals, and other venues of importance should be shown and stated well. Your should be able to hear the voice prompts which are part of the gps system clearly regardless of the cost of the device.

As technology is meant to help us you should choose the items which will provide this help. While getting the brand new products that are available can show your status and prestige you will need to pay a substantial price. A cheap gps on the other hand can give you all of the help you require for a fraction of the price.
