Question
CH4 is burned at an actual AFR of 11.2 kg fuel/kg air. What percent excess air or deficient air is this AFR? Express your answer in percent, positive if excess air or negative if deficient air. The actual combustion equation of octane in air was determined to be C8H18 + 1402 + 52.64N24CO2 + 4CO + 9H₂O + 3.502 +52.64N2 If 29.18 kg of octane was burned, how much was the excess oxygen in the products? Express your answer in kg.
