Troubleshooting Common Diesel Engine Problems EssayEngine habitude startIs the discharge reinvigorated?If un set force out is more than a month old, this fuel provide start to break down and railway locomotive st totallying (in addition to fuel strategy comp onent gumming) brush off result. Thats why its important to either drain the foul up 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 backup Fresh write down 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 simply 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 use 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 flop, following your local municipalities regulations. course 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 whitethorn 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, crawfish out any sediment from the fuel tank and add fresh, treated gas. An another(prenominal) thing to consider is that certain equipment manufacturers place a plastic packing hussy 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 fervour system. Did the locomotive locomotive engine suddenly stop afterwards striking an object? If so, you likely she ard the flywheel key, which upsets the engines ignition ( brightness level) timing.Engine Runs naughtily Is the fossil 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 suffice the oil to darken. Dark oil is not only dirty it has in like manner lost much of its ability to coat and protect engine components. Manufacturers recommendever-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 original 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 ar 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 temperatur es and rough or hilly terrain. block overfilling your crankcase. Too much oil can cause the same type of engine damage as not having enough. Air bubbles form in the oil, simplification overall lubrication. The resulting friction and metal-to-metal contact can cause premature part failure. Excess oil can also burn in the piston chamber, producing smoke and deviation vitamin C deposits.Engine Wont StartA no-start condition is one of the most frequently encountered engine problems. If there is a clicking noise provided 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 startLow or discharged batteryCorroded or loose battery cablesStarter motor put across failureIgnition switch failure big fuel pumpClogged fuel filter dish out Engine Soon LightThe Service Engine Soon light is designed to illuminate whenever a fault is detected in any of the sensors att ached to the emission, engine, or powertrain controls. The purpose of the service engine short 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 fuelsystem fault caused by an engine oil leak. An ASE certified mechanic can retrieve the problem codes from within the onboard electronic control module and determine the specific cause. Frequent service engine soon light causesLoose or scatty gas capSpark plugs or fit outs that are worn out or damagedElectronic control module failureDefective distributor or coil packsEmissions control fault such as the oxygen sensorFuel quality issue heatOverheating 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 ser ious and expensive engine damage. Proper maintenance of the cooling system is racy in order to maintain the quality of the coolant and to brand 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 amiss(p) thermostatDirty or low coolant levelNon-functioning cooling fanKinked or broken radiator hoseInternal or external coolant leakDefective radiator capDirty air filterThe Most Common sensitive Engine Problems some 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 beyondrepair. That is rarely the case, and what many small engine owners dont realize is that refilling kits are easy to use, cost effective, and can get your old mower or motorcycle wreakning 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 concealment could also be plugged or the fuel tank cap could 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 waver plug or the choke on the fuel bowl could be set in any case high. These are also relatively e asy 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 trigger plug its contacts could be dirty, the plug gap could be set incorrectly, the lam 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 compressing problem in your small engine you would want to check the valves, pistons, cylinder, or connecting rods. These could be dirty, stripped, or other than 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 vehi cle 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 supporter reduce the chance of your engine overheating. Fixing overheating problems yourselfwith replacement or repair kits is much less expensive than taking the engine in for repairs or simply secureing 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 gamey 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 uncomplete 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 glut 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 probl ems 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 ProblemsBad fuel mix A bad fuel mix can go along in several waysYou 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, meaningthat 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 com touch properly, the combustion process will not work like it should. Lack of compression might occur for these reasons Your piston rings are wor n ( giveing air/fuel to leak past the piston during compression). The intake or exhaust valves are not seal off 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 exampleIf 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 SolutionsFailure to StartThere are a number of reasons a small engine might not start properlyFuel line problems Check to see that the fuel tank is full, that the fuel is fresh, and that the shut-off valve is closed.

These could be dirty, stripped, or otherwise damaged, and would prevent the engine from starting properly or at all.Problems RunningProblems 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 newengine.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.
