WebThe Otto Cycle is an example of a reversible thermodynamic cycle. 1→2: Isentropic / adiabatic expansion: Constant entropy (s), Decrease in pressure (P), Increase in volume (v), Decrease in temperature (T) 2→3: Isochoric cooling: Constant volume (v), Decrease in pressure (P), Decrease in entropy (S), Decrease in temperature (T) WebThe fundamental distinction between otto, diesel, and dual cycle is how heat is added to the thermodynamic process. Heat is added to the engine in the Otto cycle in an isochoric manner, that is, when the piston is at top dead centre. It is a heat addition cycle with a constant volume. Diesel engines have been in use for more than a century.
