The engine in Problem 10 has a volumetric efficiency of 89% and uses isooctane as fuel at an air–fuel ratio AF=14.2 Sixty percent of the fuel that is trapped in the crevice volume at the start of combustion is later burned due to additional cylinder motion.

Calculate:

(a) HC emissions in the exhaust due to the 40% of crevice volume fuel that does not get burned. [kg/hr]

(b) Chemical power lost in these HC emissions of the exhaust. [kW]
