Theoretical air fuel ratio
Webb29 aug. 2024 · The parameter that relates the amount of air used in a combustion process is the air-fuel ratio ( AF ), which is the ratio of the mass of air to the mass of fuel. The reciprocal is the fuel-air ratio ( FA) (Eq. 11.5 ). Thus: AF=\frac {m_ {\mathrm {air}}} {m_ {\mathrm {fuel}}}\kern2em FA=\frac {m_ {\mathrm {fuel}}} {m_ {\mathrm {air}}} (11.5) WebbKnown Octane, C _{8} H _{18}, is burned completely with (a) the theoretical amount of air, (b) 150% theoretical air.
