Are diesel power generators safer and easier to use than regular gas generators?
A diesel generator combines a diesel engine with a traditional electric generator. The benefit of the diesel generator is that it allows power to be pulled without being connected to the electricity grid. It can be a valuable tool during a power outage. The generator must be the appropriate size for your power needs, however, or the system could short out.
Is a diesel engine's maximum rpm limited by the diesel burn rate?
Burning techniques are totally different when comparing Diesel and Gasoline. In Gasoline engines, air and fuel mixture is injected into the cylinder (in a non direct fuel injection system) this mixture is then compressed and thus temperature of the mixture increases, but not to the ignition temperature, this is why we need a spark plug in gasoline engines to start this small fire. After reaching the top dead level of the cylinder (or sometimes even before that ) spark plug releases its charge and start a very small explosion inside the cylinder head. This small fire ball propagates as far as there is enough fuel and oxygen. While this explosion propagates, the piston is being pushed down and turning the flywheel through the crankshaft. As you can see, you don't need to compress this air and fuel mixture till ignition temperature and you don't want to do it!!! This is why it is possible to design gasoline engines with short strokes. Short strokes means short reciprocating movements, which means faster rotational speed. In diesel engines, there is no spark plug, because ( and I'm not 100% sure about that ) Diesel is not a good fuel in propagating a controlled fireball. It just doesn't work very well in diesel. Because of that, Only air is being compressed inside a diesel engine during the compression cycle. Somewhere during compression stage, diesel is being injected inside the cylinder and starts to spread homogenously inside the cylinder, compression continues and the mixture is mixed and heated up till it reaches ignition temperature. Once ignition temperature is reached, the whole mixture explodes at the same moment. As you can see, there is no flame propagation in diesel engines, the whole mixture just explodes in a single moment. And in order to reach ignition temperature you need a long enough stroke to be able to compress air till it reaches ignition temperature of the fuel. Longer stroke means slower cycle, but higher torque. This is why Diesel engines have more torque but less speed than their gasoline counterparts. Hope this answers your question. - - - - - Okay... The Diesel engine (named after Rudolf Diesel, who invented it) was designed to burn any flammable liquid you put in it--Herr Diesel originally intended to run it on vegetable oil. OTOH, a spark ignition engine requires fuel with a minimum amount of volatility, so gasoline has to be a very highly refined product. The Diesel cycle compresses air inside the cylinder until it's hot enough to ignite the fuel. At that point, the injection system squirts a premeasured dose of fuel into a combustion chamber in the cylinder head. It ignites instantly. Because the flame front is confined to the little chamber the fuel's being injected into, there has to be a LOT of excess air in there. To get it, the engine is "oversquare"--the stroke is longer than the bore. (A Detroit Diesel DD15 is 5.47" bore, 6.43" stroke. It's an inline 6 engine that displaces 14.7 liters. Now here's where it gets fun: The DD15 comes in eight different horsepower ratings, and the only difference between the eight engines is the fuel injector system--the more power your engine has, the more fuel the injector holds. (There's also a different program in the computer, but that's another issue.) Before the EPA got all antsy about diesel emissions you could take your truck to Pittsburgh Power, have them install higher-flow injectors and have a much more powerful truck for relatively little money. (You can't do that now; the current electronic fuel injection systems on big rigs keep you from doing that.)
Does Maximum manpower requirements for power production exist during the longer term operation and maintenance?
True!
Give one reason you shouhld make the paging file maximum size the same as the paging file initial size?
From TechNet: Set the Same Initial and Maximum Size Setting the paging file's initial size and maximum size to the same value increases efficiency because the operating system does not need to expand the file during processing. Setting different values for initial and maximum size can contribute to disk fragmentation.
Where is the maximum heat produced during machining?
About 75% of heat is generated in the shear zone
What are uses of 6s maximum minimum thermometer?
Six's maximum and minimum thermometer is a popularthermometer . Its purpose is to recordthe maximum and minimum temperatures reached since the thermometer was last read. Generally speaking a minimum temperatureoccurs during the night and amaximumduring the day.. It is interesting to note that Six's maximum and minimum thermometers were still being used in 2000 of exactly the samedesign and construction as ones produced over 100 years ago. Gardeners use max-min thermometers in the greenhouse and the garden to check minimum temperatures during the cold months when frost can be a problem and to check the maximum temperature during the daytime.Gardeners use max-min thermometers in the greenhouse and the garden to check minimum temperatures during the cold months when frost can be a problem and to check the maximum temperature during the daytime.
Self-registering thermometers are used for?
Self-registering thermometers are used for measuring the maximum or minimum temperature during a period of observation. The temperature is recorded automatically.
Why is a thermostat installed in a diesel engine cooling water system?
To control and optimise the working temperature of the engine during differing load conditions.
How does a diesel engine add fuel to the compress air and it is ignited?
Diesel engine doesn't have spark plug as like petrol engine . But It has an atomizer (A plug through which fuel is sprayed into the combustion chamber).... During Intake Stroke ,the vacuum caused by piston draws air (only) into the cylinder ,Now during Compression stroke Atomizer comes to play ,Spraying Diesel into the cylinder meanwhile the piston compresses the air, so that it's temperature rises to such extent that diesel could be ignited by the heated air, and there comes the power stroke and so on... So ,Conclusion is that Diesel Engine doesn't use spark plug, but the increase in temperature of air during compression is enough to ignited the diesel.. Hope You Got The Answer
What is the temperature of Kolkata in May?
the average temperature in kolkata during the month of may to June
What do you notice about its temperature during boiling?
When a liquid is boiling the temperature stays constant. This is because the heat energy you are adding is being taken away with the vapour being produced.
Why during the ignition pressure remain constant in diesel engine?
The ignition temperature, (temperature at which diesel fuel ignites) is 490*F. This temperature corresponds to a set compression of the gasses in the cylinder of the engine. Some, but not all, diesel engines have glow plugs to initially warm the air when you first start the engine because the temperature of the air in the diesel engine is too cold to get the ignition temperature simply from compression. while the engine is running the compression heats the air to the ignition temperature. This compression (or pressure) is the same each time the cylinder fires. Using the universal gas law you can find that corresponding compression versus the ambient temperature and pressure. Typically this will occur at approximately 16 bars. Almost all diesel engines are designed to operate at a compression ratio of 15:1 - 20:1, less if supercharged or turbocharged.
What was the temperature on the Titanic?
Coal burning furnaces which produced steam to drive expansion steam engines.
What causes increased body temperature during physical activity?
Body temperature rises after exercising because the muscles have been heated up. This is what burns calories and it should even out after about 30 minutes.
What is the British Rail Class 37?
The British Rail Class 37 is a diesel electric locomotive train. There were 309 produced during the years 1960-1965. They were known by the nickname Tractors by railway enthusiasts.
What is the temperature on mercury most of the time?
Mercury is very hot in the "daytime", but very cold during the "nights". So it's not possible to give a meaningful answer really. Typical maximum temperature: 430 degrees Celsius. Typical minimum temperature: Minus 170 degrees Celsius.
