Define the process of Otto cycle
The Otto cycle is the ideal air standard cycle for petrol and gas engine.
It having of four processes.
Process 1 to 2 is isentropic compression (work input to the system).
Process 2 to 3 is constant volume heat addition to the system.
process 3 to 4 is isentropic expansion (work output to the system).
Process 4 to 1 is constant volume heat rejection to the surroundings.
An engine uses air as the operating substance. At the beginning of compression the pressure is 90 KN /m 2 and the temp. is 40 0 C. During the adiabatic compression, the volume is
