Gas is sampled at atmospheric pressure from the exhaust manifold of an internal combustion engine and analyzed. The mole fractions of the species in the exhaust are: y(H2O) = 0.0861; y(CO2) = 0.0584; y(O2) = 0.0995; y(N2) = 0.756 Other species such as CO and unburned hydrocarbons can be neglected. a) Assuming that the fuel is a synthetic fuel derived from coal with formula CH. determine the atomic hydrogen to carbon ratio of the fuel (i.e. z or B/a). b) Calculate the fuel-air equivalence ratio at which this engine is operating. c) Is the engine a conventional spark-ignition or a diesel one? Explain.
