A typical otto cycle is a thermodynamic cycle that describes the working of an ideal spark ignition piston engine. The Otto cycle is most commonly utilized in automobile engines.
The Otto cycle is a portrayal of what befalls a mass of gas as it is exposed to changes of pressing factor, temperature, volume, expansion of heat, and expulsion of heat. The mass of gas that is exposed to those progressions is known as the system. The system, for this situation, is characterized to be the liquid (gas) inside the chamber. By depicting the progressions that occur inside the system, it will likewise portray in converse, the framework’s impact on the climate. On account of the Otto cycle, the impact will be to create a sufficient network from the system in order to drive a vehicle and its inhabitants in the climate.
There are two processes in the Otto cycle, the first is the isoentropic process and the other one is the isochoric process.
In the above diagram:
1-2: Adiabatic compression
2-3: Isochoric heat addition
3-4: Adiabatic expansion
4-1: Isochoric heat rejection
Heat supplied during constant volume process 2-3 is given by:
Heat rejected during constant volume process 4-1 is given by:
The thermal efficiency of the Otto cycle is given:
Frequently Asked Questions
What is meant by the Otto cycle?
Ans: The Otto cycle is an analysis of what happens to a mass of gas as it is exposed to changes of pressure, temperature, volume, expansion of heat, and expulsion of heat. The mass of gas that is exposed to those changes is called the system.
What are the Otto cycle and diesel cycle?
Ans: Otto cycle is utilized for petroleum or flash start motor while diesel cycle is utilized for diesel or pressure start the motor. The primary distinction between the Otto cycle and the Diesel cycle is that in the Otto cycle heat expansion happens at a consistent volume and in the diesel cycle heat expansion happens at a steady pressure.
