We wish to model a gasoline engine for an automotive application with the ideal Otto cycle. The compression ratio is 10. The heat added is 2965 kJ/kg.  For a 4 stroke engine, what is the engine displacement in liters to produce 500 hp at a rotational speed of 5000 rpm.    The inlet pressure is 100 kPa and the inlet temperature is 27 deg C

Multiple Choice. Choose the correct answer and show COMPLETEsolution. (Diesel cycle)

A compression-ignition engine with compression ratio of 14 is being designed. Pressureand temperature at the bottom dead centre are 1.3 bar and 400K. The engine operatesaccording to the standard Diesel cycle. Assume polytrophic index to be 1.33. Computepressure and temperature at the top dead centre

An air-standard dual cycle has a compression ratio of 9.1 and displacement of Va= 2.2L.At the beginning of compression, p1= 95 kPa, and T = 290 K. The heat addition is 5 kJ, with one quarter added at constant volume and the rest added at constant pressure. Determine: a) each of the unknown temperatures at the various states, in K. b) the net work of the cycle, in kJ. c) the power developed at 3000 cycles per minute, in kW. d) the thermal efficiency. e) the mean effective pressure, in kPa. Step 1 Your Answer Correct Answer (Used) Determine each of the unknown temperatures at the various states, in K. 684.1 K T3 = K 1217 T4 = 2311 K 1440 K Step 2 X Your answer is incorrect.
