ultraviolet light
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.
What is the maximum temperature recorded on the thermometer during distillation?
The maximum temperature recorded on the thermometer during distillation is the boiling point of the liquid being distilled. This is the temperature at which the liquid changes state from liquid to vapor. It is important to closely monitor this temperature to ensure proper separation of components during distillation.
Where is the maximum heat produced during machining?
About 75% of heat is generated in the shear zone
What is the maximum and minimum temperature on mars?
The maximum temperature on Mars can reach around 70 degrees Fahrenheit (20 degrees Celsius) near the equator during the day, while the minimum temperature can plummet to about -195 degrees Fahrenheit (-125 degrees Celsius) at the poles during the night.
Maximum and minimum temperature of mars?
The maximum temperature on Mars can reach around 70°F (20°C) near the equator during the day, while the minimum temperature can drop to about -195°F (-125°C) at the poles during the night. Mars has extreme temperature variations due to its thin atmosphere and distance from the Sun.
What are uses of 6s maximum minimum thermometer?
A 6s maximum minimum thermometer is commonly used to measure the highest and lowest temperatures reached over a period of time, such as a day or a week. It is often used in meteorology, agriculture, and environmental monitoring to track temperature fluctuations accurately.
What are the advantages and disadvantages of reversing thermometer?
Advantages: Can measure the maximum temperature reached during a period; no need to constantly monitor the temperature; suitable for applications requiring monitoring of peak temperatures. Disadvantages: Cannot measure the current temperature; once reset, the maximum temperature reading is lost; limited usefulness for continuous temperature monitoring.
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 difference between maximum and minimum temperature of a day?
The maximum temperature of a day is the highest temperature recorded during that day, while the minimum temperature is the lowest temperature recorded. These values help to understand the range of temperatures experienced during a particular day.
What are the maximum and minimum temperatures?
The maximum temperature refers to the highest recorded temperature within a specified time period, while the minimum temperature indicates the lowest recorded temperature during that same timeframe.
What is the temperature of Kolkata in May?
the average temperature in kolkata during the month of may to June
