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...

14. An I.C engine operating on Limited Pressure Cycle has a cylinder bore and stroke length of 250 mm and 400 mm respectively. Its compression ratio and expansion ratio are 9 and 5 respectively. The initial pressure and temperature of the air are 1 bar and 30°C. The heat added at constant pressure is twice the heat rejected at constant volume. The compression and expansion follows the law pv 1.25 - constant. Determine: (Pressures and temperatures at all salient points....
