The thermal energy when the spark-ignition engine operates on an Otto cycle with a compression ratio of 9 and temperature limits of 30°C and 1000oC is 58%.
From the information given, we are told that spark-ignition engine operates on an Otto cycle with a compression ratio of 9 and temperature limits of 30°C and 1000oC.
The thermal energy will be:
= 1 - 1/(1.4 - 1)
= 0.58
= 58%
Also, the mass flux of air will be illustrated below:
T2 = 729.70k
W = 224.60kj
Therefore, the mass flux will be:
= 500/224.60
= 2.226kg/s
In conclusion, the the mass flux will be 2.226kg/s.
