A four-cylinder, 3.6-liter, four-stroke cycles Sl engine operates at 2700 RPM with a volumetric efficiency of 87 %.
The fuel used is methyl alcohol.
The chemical reaction of methyl alcohol in a Stoichiometric condition is:
CH3OH + 1.5(02 + 3.76N2) - CO2 + 2H20 + 1.5(3.76N2)
The chemical reaction of methyl alcohol in an equivalence ratio of o = 1.23 is:
CH3OH + m(02 + 3.76N2) → NCO2 + pCO + 2H20 + m(3.76N2)
During combustion, all hydrogen is converted to water, and all carbon is converted to CO2 and CO.
The density of standard air is 2.25 kg/m. The atomic masses are as follows: H=1, C=12, 0-16, and N=14.
Calculate the following:
m is
n is
p is
Mole fraction of CO in the exhaust is
The mass flow rate of air into the engine is
gram/s.
