Methanol is burned in an engine with air at an equivalence ratio of

=0.75. Exhaust pressure and inlet pressure are 101 kPa. Write the balanced chemical equation for this reaction.

Calculate:

(a) Air–fuel ratio. (b) Dew point temperature of the exhaust if the inlet air is dry. [°C]

(c) Dew point temperature of the exhaust if the inlet air has a relative humidity of 40% at 25°C. [°C]

(d) Anti-knock index of methanol.
