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.
