Question:
The ultimate analysis of a sample of petrol was 85.5% C and 14.5% H.
Calculate
(i) the stoichiometric A/F ratio;
(ii) the A/F ratio when the mixture strength is 90%;
(iii) the A/F ratio when the mixture strength is 120%;
(iv) the analyses of the dry products for (ii) and (iii);
(v) the volume flow rate of the products through the engine exhaust per unit rate of fuel consumption for (iii) when the pressure is 1.013 bar and the temperature is 110 oC.
