1. Intake air into a 4-stroke, 4-cylinder otto engine is 100 kPa, 21°C with an air-fuel ratio of 15. The heating value of fuel is 43,966 kJ/kg. The ideal cycle efficiency is 50%. The actual engine has a volumetric efficiency of 75%. The piston speed is 816 m/min at 4000 rpm. Stroke-to-bore ratio is 1.1, and brake engine efficiency is 55%. Use hot air std. k = 1.33. For air, R = 287.08 J/kg K. Find (a) combustion pressure in bar (b) shaft torque in N-m (c) brake thermal efficiency in % (d) brake mean effective pressure in bar
In a 4-stroke ideal diesel cycle; The cylinder volume is 0.96 liters when the piston is in bottom dead center, and the cylinder volume is 0.06 liters when it is in top dead center. At the beginning of compression, the temperature is T1 = 336 K, P1 = 98 kPa. 1.64 kJ / cycle heat is released as a result of combustion. The mechanical efficiency of the 6-cylinder engine operating at n = 1860 rpm is m = 0.84. Since Cv = 716.5 J / kg K, Cp = 1003.5 J / kg K, R = 287.13 J / kg K; a) Thermodynamic values at the cycle points, b) Effective power of the engine.
