There are 2 isochoric and 2 isentropic processes. It works on petrol engine also.

Otto cycle works on petrol engine so this is a constant volume process so option C is correct.

Otto cycle works on constant volume and 2 isentopic process.

Otto cycle consists of two isentropic process and two constant volume process.

Option C is the correct answer.
But it's more logical and traditional that reversible adiabatic compression (isentropic compression) commences the cycle while heat addition at constant volume (isochoric heat addition) follows before adiabatic expansion (isentropic expansion) and the cycle ends with constant volume heat rejection (isochoric heat rejection).
Thanks.

In Otto cycle, the combination of 4 reversible cycle 2 isentropic and 2 constant volume process in this process heat addition is constant volume and heat rejection at constant volume.
Hence in this figure, the correct answer is c.
Hence in this figure, the correct answer is c.

It is a wrong diagram.
Process 1 to 2 is compression process so temp will always increase rather than decrease.

Addition of heat takes place in Otto cycle during constant volume process.
