Troubleshooting Common Diesel Engine Problems Essay Example for Free

Troubleshooting Common Diesel Engine Problems Essay Engine wont start Is the fuel fresh? If untreated fuel is more than a month old, this fuel will start to break down and engine stalling (in addition to fuel system component gumming) can result. Thats why its important to either drain the gas from your outdoor power equipment before it sits idle during the winter, or add a fuel preservative/stabilizer to the fuel. To prevent the fuel from going stale purchase a replacement Fresh Start Fuel Cartridge for your Fresh Start Fuel Cap, OR purchase our Advanced Fuel Treatment and mix the prescribed amount with your gasoline. Even better, keep a gas can solely for your outdoor power equipment filled with gasoline treated with our Advanced Fuel Treatment. That way, you will always have a supply of fresh, treated fuel used specifically for your outdoor power equipment. If youve got stale gas in your equipment, drain the gas from the fuel tank completely and dispose of it properly, following your local municipalities regulations. NOTE: In most cases, this older fuel can be added to your cars fuel tank with no harmful effects. Sometimes removing the old fuel and replacing with fresh, treated fuel may just solve the problem. If not, drain the old fuel and spray the inside of the fuel tank and carburetor with some carburetor cleaner. Finally, remove any sediment from the fuel tank and add fresh, treated gas. Another thing to consider is that certain equipment manufacturers place a plastic packing plug between the gas cap and gas tank. In order for there to be proper venting, ensure that this plug is removed. If stale fuel is not at fault, next look at the ignition system. Did the engine suddenly stop after striking an object? If so, you likely sheared the flywheel key, which upsets the engines ignition (spark) timing. Engine Runs Poorly Is the oil level low? When you pour fresh oil into the crankcase, its a golden or amber color. Gradually, the heat, dirt particles and agitated air in the crankcase cause the oil to darken. Dark oil is not only dirty; it has also lost much of its ability to coat and protect engine components. Manufacturers recommend  changing the oil in your small engine after every 25 hours of operation. For a new engine, youll also need to change the oil after the first five hours of operation. New engines require this extra step to flush out small particles that accumulate naturally during the break-in period. Hours of use are just one factor in determining how often the oil should be changed; the amount of wear and tear is equally important. Just like the oil in a vehicle operated in extremely dirty or dusty conditions or at high speeds, the oil in a lawn mower or other small engine breaks down faster under tough conditions, such as wet grass, heavy dust, high temperatures and rough or hilly terrain. Avoid overfilling your crankcase. Too much oil can cause the same type of engine damage as not having enough. Air bubbles form in the oil, reducing overall lubrication. The resulting friction and metal-to-metal contact can cause premature part failure. Excess oil can also burn in the cylinder, producing smoke and leaving carbon deposits. Engine Wont Start A no-start condition is one of the most frequently encountered engine problems. If there is a clicking noise but the engine does not crank it generally indicates a battery issue. An engine that cranks but will not start is indicative of a fuel or ignition problem. Common reasons an engine wont start: Low or discharged battery Corroded or loose battery cables Starter motor relay failure Ignition switch failure Defective fuel pump Clogged fuel filter Service Engine Soon Light The Service Engine Soon light is designed to illuminate whenever a fault is detected in any of the sensors attached to the emission, engine, or powertrain controls. The purpose of the service engine soon light is to alert the driver to a potentially serious fault that requires repair. Blue exhaust smoke along with the service engine soon light may indicate a fuel  system fault caused by an engine oil leak. An ASE certified mechanic can retrieve the trouble codes from within the onboard electronic control module and determine the specific cause. Frequent service engine soon light causes: Loose or missing gas cap Spark plugs or wires that are worn out or damaged Electronic control module failure Defective distributor or coil packs Emissions control fault such as the oxygen sensor Fuel quality issue Overheating Overheating is most generally caused by a low coolant level. A quick check of the coolant overflow reservoir will indicate if coolant is leaking. Most cars are equipped with temperature gauges or warning lights that will alert the driver to an overheating issue. Frequent overheating can cause serious and expensive engine damage. Proper maintenance of the cooling system is vital in order to maintain the quality of the coolant and to make certain the cooling system is in good operating condition. Additionally, a cracked head or blown head gasket can also cause overheating, coolant loss and white exhaust smoke, which may indicate the need for engine repair. Common reasons for overheating: Faulty thermostat Dirty or low coolant level Non-functioning cooling fan Kinked or broken radiator hose Internal or external coolant leak Defective radiator cap Dirty air filter The Most Common Small Engine Problems Many owners of small engine vehicles such as lawnmowers, golf carts, motorcycles and snowmobiles make the costly mistake of replacing their engines or entire vehicles simply because they believe the engine is beyond  repair. That is rarely the case, and what many small engine owners dont realize is that replacement kits are easy to use, cost effective, and can get your old mower or motorcycle running like new again. The first thing to do when considering a small engine replacement kit is to identify what is wrong with your current engine. Problems fall into two basic categories; failure to start and problems running after the engine has started. Just because your engine wont start doesnt mean it is dead. There are a number of reasons an engine might not start. There may be fuel line problems. Make sure you check to see that the fuel tank is full, that the fuel is fresh, and that the shut-off valve is closed. The fuel line or inlet screen could also be blocked or the fuel tank cap c ould be clogged. These are basic fuel line problems that can easily be remedied with replacement and repair kits. Carburetor problems are another reason an engine might not start. The carburetor could be blocked or the engine could be flooded. There might be problems with the spark plug or the choke on the fuel bowl could be set too high. These are also relatively easy problems to fix with the appropriate instructions and equipment. Another obvious cause for a dead engine is an ignition problem. A number of things could be wrong with the spark plug; its contacts could be dirty, the plug gap could be set incorrectly, the lead could be faulty, or the kill switch could be shorted. These all require basic replacement or repair and are a snap with a proper kit. If you have a compression problem in your small engine you would want to check the valves, pistons, cylinder, or connecting rods. These could be dirty, stripped, or otherwise damaged, and would prevent the engine from starting properly or at all. Many small engines will start correctly but have problems running properly. These can pose more danger to your vehicle than an engine that simply wont start. If left to themselves, simple problems such as overheating and emitting smoke can eventually ruin an engine and require a full-on replacement. Overheating engines can be dangerous for a vehicle as well as its operator. Lack of oil is one of the most common reasons for overheating, as is a dirty engine. Beyond that, there may be shrouds or cooling fans missing within the engine or the gasket could be leaking. The fuel mixture might be too lean, another carburetor problem. Simply cleaning or replacing the fuel tank vent and fuel tank screen can also help reduce the chance of your engine overheating. Fixing overheating problems yourself  with replacement or repair kits is much less expensive than taking the engine in for repairs or simply buying a new engine. If your small engine is emitting smoke you might think you need to replace the engine or vehicle. Not likely. If the engine is emitting blue or white smoke then it is probably burning oil. If it is emitting black smoke it is most likely a problem with a carburetor. If it is neither the carburetor nor an oil leak, then it might be the air filter. A plugged or dirty air filter can cause an engine to smoke. A knocking engine is a loud and obvious indicator that something is wrong with your small engine. If your engine experiences knocking it may indicate an excess of carbon in the combustion chamber, which would require you to clean carbon from the piston and head. The flywheel might also be loose, and should be replaced as needed. Another reason for engine knocks is a faulty spark plug lead, easily tested, repaired and replaced with the appropriate replacement kit. Speaking of spark plugs, a small engine might run poorly if the spark plug repeatedly misses under load. This could be caused by any number of things, including a faulty spark plug, faulty breaker points, an incorrectly set carburetor, or a weak valve spring. All these problems can be repaired at home with a specific repair kit. It may be tempting to simply buy a new small engine vehicle or tool when the engine starts to give you problems, but it is hardly cost-effective and doesnt guarantee you wont run into the same problems a few months down the road. Small engine replacement and repair kits are affordable, easy to use, come with the most advanced technology, and most are back by a warrantee. And with todays economy the way it is, buying a new vehicle when your engine experiences problems is silly. Fix the problem yourself with a detailed replacement kit. It just makes sense. Engine Problems Bad fuel mix A bad fuel mix can occur in several ways: †¢You are out of gas, so the engine is getting air but no fuel. †¢The air intake might be clogged, so there is fuel but not enough air. †¢The fuel system might be supplying too much or too little fuel to the mix, meaning  that combustion does not occur properly. †¢There might be an impurity in the fuel (like water in your gas tank) that makes the fuel not burn. Lack of compression If the charge of air and fuel cannot be compressed properly, the combustion process will not work like it should. Lack of compression might occur for these reasons: †¢Your piston rings are worn (allowing air/fuel to leak past the piston during compression). †¢The intake or exhaust valves are not sealing properly, again allowing a leak during compression. †¢There is a hole in the cylinder. The most common hole in a cylinder occurs where the top of the cylinder (holding the valves and spark plug and also known as the cylinder head) attaches to the cylinder itself. Generally, the cylinder and the cylinder head bolt together with a thin gasket pressed between them to ensure a good seal. If the gasket breaks down, small holes develop between the cylinder and the cylinder head, and these holes cause leaks. Lack of spark The spark might be nonexistent or weak for a number of reasons: †¢If your spark plug or the wire leading to it is worn out, the spark will be weak. †¢If the wire is cut or missing, or if the system that sends a spark down the wire is not working properly, there will be no spark. †¢If the spark occurs either too early or too late in the cycle (i.e. if the ignition timing is off), the fuel will not ignite at the right time, and this can cause all sorts of problems. Many other things can go wrong. For example: †¢If the battery is dead, you cannot turn over the engine to start it. †¢If the bearings that allow the crankshaft to turn freely are worn out, the crankshaft cannot turn so the engine cannot run. †¢If the valves do not open and close at the right time or at all, air cannot get in and exhaust cannot get out, so the engine cannot run. †¢If someone sticks a potato up your tailpipe, exhaust cannot exit the cylinder so the engine will not run. †¢If you run out of oil, the piston cannot move up and down freely in the cylinder, and the engine will seize. Small Engine Problems And Simple Solutions Failure to Start There are a number of reasons a small engine might not start properly: Fuel line problems: Check to see that the fuel tank is full, that the fuel is fresh, and that the shut-off valve is closed. The fuel line or inlet screen could also be blocked or the fuel tank cap could be clogged. Carburetor problems: The carburetor could be blocked or the engine could be flooded. There might be problems with the spark plug. Check the choke on the fuel bowl as well it could be set too high. Ignition problems: The spark plug contacts could be dirty, the plug gap could be set incorrectly, the lead could be faulty, or the kill switch could be shorted. These all require basic replacement or repair and are a snap with a proper kit. Compression problems: Check the valves, pistons, cylinder, or connecting rods if you suspect a compression problem. These could be dirty, stripped, or otherwise damaged, and would prevent the engine from starting properly or at all. Problems Running Problems running properly can pose more danger to your vehicle than an engine that simply wont start. If left unfixed, constant overheating or smoke emission can eventually ruin an engine and require a full-on replacement. Overheating engines: Lack of oil is one of the most common reasons for overheating. So is a dirty engine. Beyond that, there may be shrouds or cooling fans missing within the engine or the gasket could be leaking. The fuel mixture might be too lean, another carburetor problem. Cleaning or replacing the fuel tank vent and fuel tank screen can help reduce the chance of your engine overheating as well. These are all fixes that you can do yourself or with some simple repair kit that will cost far less than a new  engine. Smoking: If the engine is emitting blue or white smoke then it is likely burning oil. If it is emitting black smoke it is a problem with the carburetor most likely. If it is neither the carburetor nor an oil leak, then it might be a clogged or dirty air filter. Knocking engine: If your engine experiences knocking it may indicate an excess of carbon in the combustion chamber, which would require you to clean carbon from the piston and head. The flywheel might also be loose. A faulty spark plug lead could cause engine knocking. This can be easily repaired or replaced. Spark Plug Misses: This could be caused by any number of things, including a faulty spark plug, faulty breaker points, an incorrectly set carburetor, or a weak valve spring.

Its Time to Reform the Endangered Species Act Essay -- Argumentative

It's Time to Reform the Endangered Species Act In 1973, Congress passed the Endangered Species Act. The Act was passed in response to findings by Congress that growth and development were responsible for the extinction of species of fish, wildlife and plants. This Act was to provide programs to protect species identified as either endangered or threatened. It also mandated Federal agencies and departments to protect endangered and threatened species in their own operations, as well as work with State and local agencies to further promote conservation and protection of identified species. By the definition of the Endangered Species Act, a species covered by the legislation is either classified â€Å"Endangered† if threatened with extinction, or â€Å"Threatened† if in a state of decline that might place it on the endangered list. As of 23 March 2003, 1262 species of plants and animals were listed as endangered or threatened by the Endangered Species Act, with thirty-three species proposed for listing. To date, twenty-six species have been removed from the list, either due to recovery or the discovery of new information about their status, while seven were removed due to becoming extinct. THIRTY YEARS LATER: NEW LOOKS AT THE SUCCESS OF THE ACT There are concerns about the Endangered Species Act upon business, industry, and property owners, as well as Wildlife groups, about the effectiveness of the Act in protecting and restoring listed species. A report from the Ecological Society of America entitled â€Å"Strengthening the Use of Science in Achieving the Goals of the Endangered Species Act†, calls upon the Federal government to adopt a more-proactive approach in species preservation.

Nursing as a career Essay

           Nursing as a Career, Vocation, or Job? Nursing as a Career, vocation or just a job is a question that may receive many different answers. In my own personal opinion, I think that Nursing could be all three for different people or even all three things for the same person. Is it so hard to believe that someone’s job is their career, and even that the person is lucky enough to have a career/job as their vocation in life? I think not. A job is something that one gets paid for, makes a living off of it and takes pride in their work. A career is a lifelong commitment to a job or line of work. You get paid for it, you sometimes get benefits and even get to retire. A vocation is a calling in life. It is God’s chosen area for one to work in or do. It is a special talent. â€Å"Individual nursing practice is determined by the career path selected and is dependent upon education, experience, work setting and geographical location. Nurses may follow their personal and professional interests by working with any group o f people, in any setting, at any time. There is no profession which offers as many opportunities for diversified roles as does nursing.† (Sigma Theta Tau,2014) â€Å"Using Blum’s model of vocations it is argued that such occupations are socially expressed within practices embodying traditions, norms and a range of meanings: industrial, social, personal and moral. Vocational workers are those who identify in certain ways with these traditions, norms and meanings.†(PubMed, 2002) â€Å"Nursing as a job requires not only treating patients who are sick and injured, but also offering advice and emotional support to patients and their families, taking care of paperwork (lots and lots of paperwork), helping doctors diagnose patients and providing advice and follow-up care.† (Snagajob,2014)

Economic and Social Groupings Essay - 1244 Words

Global social and economic groupings have significant beneficial effects for their members. Discuss the extent to which you agree with this statement (40) It is beneficial to us when assessing said statement to begin by considering the main reasons for the formation of social and economic groupings. First and foremost considering the 4 main types of alliances. Between Free Trade Areas and Customs Unions it is fair to say that the main goal is to restrict imports from non-member countries, in turn allowing the economies of the member countries to flourish and provide for themselves, amongst themselves, in terms of trade. Common Markets on the other hand keep import tariffs in place, instead allowing the free movement of labour and†¦show more content†¦This is feared to possibly lead towards cultural homogenisation, as member countries begin to lose their identities certainly politically, as the EU becomes a supposed super-state. While others will argue that this social grouping allows for a more peaceful situation between all member countries, this was especially true following World War 2; which in itself lead to the creation of the EU. As well as arguing that the EU allows for more accessible travel, allowing European citizens to discover different cultures and live in better harmony. Another well know grouping is NAFTA, a free trade agreement created in 1994 between the United States, Canada and Mexico. This created one of the largest free trade areas of the world. Its success has been astounding boosting trade between the member countries from $306bn to $930bn. However in more recent assessments it has been suggested that in the long haul it has been more damaging than helpful for Mexico; as an LEDC at the time some suggest it may have exploited. Suggestions are based on the assumptions that as a result of the NAFTA agreement Mexicos rate of development has been hindered. The most basic measure of economic progress, especially for a developing country like Mexico, is the growth of income (or GDP) per person.
