How does the thermal efficiency of an ideal Otto Cycle change with the compression ratio of the engine and the specific heat ratio of the working fluid?
The answer is 38.
Why Air Standard Cycles are conceived?
Air standard cycles are conceived to permit thermodynamic calculations using the well-known and readily available thermodynamic properties of air. The results of such calculations may be used to predict compression ratio, specific heat ratio, and other operating parameters effects on thermal efficiency of a number of heat engines such as the Otto Cycle Heat Engine , the Diesel Cycle Heat Engine, and the Brayton Cycle Heat Engine.
What is the application of Otto cycle in industry?
all four stroke engines
Can you convert a gas engine into a diesel?
It would definitely not be possible to convert a gas engine into a diesel engine because the cylinder block and head would not be strong enough. A diesel engine needs a much higher compression ratio than a gas engine, which means the gas engine's cylinder block and cylinder head would probably explode under the higher pressure. You would have to change so many things: * the crankshaft, to get a longer piston stroke, because the compression ratio for gas is much lower than for diesel; * the connecting rods and pistons * the cylinder head and camshaft to get the right valves and holes for diesel fuel injectors instead of spark plugs * the fuel injectors and fuel pump - and maybe the tank too, to get the right vents and filler cap for diesel instead of gas * the exhaust system to get the right catalytic converter for diesel * the gears in the gearbox to get the right gear ratios to suit a diesel engine * diesel does not use any spark plugs so you would have be sure to use a safe method to disable the high voltage ignition system (which supplies sparks for gas ignition) and replace it by the right kind of electronic engine management unit to control the diesel fuel injectors * etc. In short, it would not make sense to try to do it from a cost point of view. You could perhaps buy a reconditioned diesel engine made to go in the same model of car, but, unless you could fit it yourself along with all the other bits and pieces, it would be far cheaper just to buy a secondhand diesel model of your vehicle and sell your present gas model.
Why is diesel is not used in petrol engines?
Because diesel is ignited of heat and high high compresion not a spark on lower compresion petrol engine. If you use diesel in a petrol you will end up with your engine knocking and pre-detonation followed by your engine blowing up pretty bad.
If compression ratio is samethen whose efficiency will be greater diesel cycle or otto cycle?
Diese
Which is more efficient otto engine or diesel engine?
diesel cycle
Otto cycle and Diesel cycle with p-v diagram?
165.266
What is the difference between otto cycle and diesel cycle?
the difference is the heat addition type In Otto Cycle the heat addition is Isochoric ((constant volume)) In Diesel Cycle the heat addition is Isobaric ((constant pressure))
Why otto cycle used for petrol engine and diesel cycle for diesel engine?
A standard 20 to 1 otto cycle is used for the petrol and diesel cycles for diesel engines. It is higher than gasoline engines due to the way diesels burn and compress fuel.
Why does the heat is added at constant volume in Otto cycle and at constant pressure in Diesel cycle?
in otto cycle the burning of fuel is instantaneously therefore a very small voulme is required for burning of fule
What is the efficiency of the Otto cycle formula and how can it be optimized for maximum efficiency?
The efficiency of the Otto cycle is given by the formula: Efficiency 1 - (1 / compression ratio)(-1), where is the specific heat ratio. To optimize the efficiency of the Otto cycle for maximum efficiency, you can increase the compression ratio, improve combustion efficiency, reduce heat losses, and use higher octane fuel.
What is the formula to calculate the thermal efficiency of an Otto cycle engine?
The formula to calculate the thermal efficiency of an Otto cycle engine is: Thermal Efficiency 1 - (1 / compression ratio)
How does the thermal efficiency of an ideal Otto Cycle change with the compression ratio of the engine and the specific heat ratio of the working fluid?
The answer is 38.
When was the four stroke petrol engine was invented?
The 4 stroke or 4 cycle engine was invented in 1876 Nicholas Otto in Germany. This is the earliest 4 stroke and is commonly called the Otto cycle engine. The Diesel 4 stoke was invented in 1893 by Rudolph Diesel in Germany.
What are the factors that contribute to the efficiency of the Otto cycle?
The efficiency of the Otto cycle is influenced by factors such as compression ratio, combustion process, and heat transfer. These factors impact the amount of work produced by the engine relative to the energy input.
What is the Otto cycle efficiency formula and how can it be used to calculate the efficiency of an engine?
The Otto cycle efficiency formula is given by: Efficiency 1 - (1 / compression ratio)(-1), where is the specific heat ratio of the working fluid. This formula can be used to calculate the efficiency of an engine by plugging in the compression ratio and specific heat ratio values. The higher the efficiency value, the more effectively the engine converts fuel into useful work.
