An SI engine operating on stoichiometric propane fuel burns 0.00005 kg of fuel in each cylinder
during each cycle with a combustion efficiency of 95%. When combustion starts at the end of
compression, the temperature and pressure in the cylinder are T 700 K and P = 2000 kPa.
Exhaust temperature leaving the cylinder after combustion is Tex = 1200 K.
Calculate:
1. combustion heat input into each cylinder during each cycle using Q = E N,h; - E N,h,
PROD
REACT
2. heat input using Qin = nm,QLHV
Indicate the source of the Tables of Properties used in your calculation. Assume Ah; = 29,711k] /kmol for
%3D
propane gas.
