Problem 1 - ./~/ In an ideal Otto cycle of air, suppose the air is compressed to 650 K and 1800 kPa before heat addition, and waste heat is rejected at 680 K and 180 kPa. Account for the variation of air's specific heats and determine a. b. C. ) Sketch the processes of the cycle on a T-s diagram. On the diagram, clearly specify the conserved quantity / quantities of each process. the air's internal energy at the beginning of each process; J () the heat added to each kg of air and the heat rejected by each kilogram of air;
3. A rear mounted air-cooled SI engine has 6 cylinders, 3.375 in x 2.6 in bore and stroke respectively, acompression ratio of 8 and developed 80 BHP at 4400 rpm. It was noted that brake thermal efficiency is26 %, volumetric efficiency is 74 % and mechanical efficiency is 71 %. For the ideal cycle, conditions atthe start of compression are 14.7 psia, 140 o F.Calculate a) Percent clearance, b) P, T at the end of compression, c) Brake engine efficiency, d) massflow rate of air, e) torque (lb-ft), f) AF with Q hv = 19100 BTU/lb fuel
Part (a) Find the efficiency of an ideal engine operating between these reservoirs. Remember the efficiency is unit-less, therefore so should your number be as well. ( Party a was incorrect can you try again ) Part (d) What if the actual work done (more realistically) is W = 290 J during a single cycle; what is the efficiency of this engine if the energy input is the same (again, the number should be unit-less)? Part (e) What is equation for the new power output per cycle (in Watts) of this new (and more realistic) engine?
