Question
An ideal 4-stroke Otto cycle at the
beginning of the compression process has
air at 1 atm, 20°C and contains a volume
inside of 1.6 It. At the end of the
compression process the volume inside the
engine is reduced to 0.2 It. At the end of the
constant volume heat addition process the
temperature reaches 1200°C. The motor
operates at 3500 r.p.m. Find: a) The specific
net work of the cycle, b) The efficiency of
the cycle, c) The power net cycle work.
answers:
a) Wnet =- 323.65kJ / kg
b) ŋOtto =56.3 %
c) Wnet =18.20 kW
