Bll An engine having a bore of 130 mm, stroke of 164 mm and compression ratio is 9. It used a fuel mixture of 40% C4H10 (butane) and 60% C,H3 (propane). The dry products of combustion is CO2=15%, CO=1.5%, O2=2.5% and the rest is N2. Calculate: a- the air/fuel ratio b-the mass of the residual gases left in the cylinder at the end of the exhaust stroke if the pressure and temperature are 1.5 bar and 680 K.

BII An engine having a bore of 130 mm, stroke of 164 mm and compression ratio is 9. It
used a fuel mixture of 40% C,H10 (butane) and 60% C,H3 (propane). The dry products of
combustion is CO2=15%, CO=1.5%, O2-2.5% and the rest is N2. Calculate:
a- the air/fuel ratio
b-the mass of the residual gases left in the cylinder at the end of the exhaust stroke if the
pressure and temperature are 1.5 bar and 680 K.
