Problem 3 In modern high-speed compression ignition engines, fuel is injected into the combustion chamber much sooner than in early diesel engines. That means, heat is added partly at constant volume and partly at constant pressure. The advantage of this modification is that more time is available for the fuel to completely combust. The ideal dual cycle consists of the following operations: • Process -: Isentropic compression • Process -3: Addition of heat at constant volume. • Process - Addition...
