An ideal dual combustion cycle operates on 454 kg. of air. At the beginning of compression, the air is at 96.53 kPa, 43.3-degree Celsius. Pressure ratio is equal to 1.5, cut-off ratio is 1.6, and compression ratio is 11. Using the air properties, determine (a) the percentage clearance (b) the pressure, the volume, and the temperature at each corner of the cycle, (c) Heat added, Heat rejected, and work net, (d) the thermal efficiency (e) the MEP in kPa.

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....

2. Analyze an Audi 3.0-liter TDI V6 Biturbo diesel engine using an air-standard Diesel cycle that addresses the "real" effects of non-isentropic compression/expansion, air-fuel ratio, fuel heating value, incomplete combustion, exhaust residual, and heat loss. The engine is four-stroke, has six cylinders with a compression ratio of 16.0, and develops maximum power at 4250 rpm. Assume the following: the diesel fuel heating value is Quv 42,600 kJ/kg, the air-to-fuel ratio (AF) at maximum power is 25, and the combustion efficiency...
