Yes otto cycle consists of two constant volume and two isentropic processes.

Otto cycle (OR) constant volume cycle.
It consists of two constant volume process for heat addition, heat rejection as well as two isentropic processes.

Hmmm because it consists of 2 isochoric and 2 isentropic process.

Otto cycle consists of four process 2-isentropic process and 2-constant volume process (heat addition and heat rejection). It is also called SI engine cycle.

As the temperature at every points are different so correct answer is C.

There is very minor difference b/w const pr & cost vol curve in t s diagram. B/W same temp range const pr curve will be more dipper.

In Otto cycle curve 1-2 and 2-3 are isentropic (adiabatic) so on t-s dia entropy for adibatic process is constant so C is correct.

In Otto cycle heat inter and reject at constant volume.

Otto cycle 2 constant volume processes.

2 constant volume and two isotropic process.
