The Equivalence Ratio: The Key To Understanding; A necessary compliment to the ER for exact calculations is the Air/Fuel (A/F) ratio. Hydrocarbons and biomass have very different compositions, so for final calculations it is also necessary to calculate the actual air/fuel ratios from the fuel composition.

In addition, for a spcified fuel concentration with air, the equivalence ratio can be calculated - and vica versa. ... References: Bjerketvedt, D., Bakke, J.R. and Wingerden, K. van (1993) "Gas explosion handbook" Version1.2 ; Equivalence ratio in Wikipedia; Stoichiometry in Wikipedia...

The engine performance is dependent on the air/fuel ratio and the following graphs show how the fuel consumption, Carbon Monoxide and NOx emmisions depend upon this ratio.

Input mixture ratio, combustion pressure and oxygen:nitrogen ratio, in the oxidiser, are varied to produce results at constant pressure, constant equivalence ratio or constant mass flow rate and residence time respectively.

The fuel chemical composition is required to calculate the stoichiometric value. The heat release rate and the fuel loss rate within the room are also required. Finally, the correlation of the yield rates of the species to the equivalence ratio is required.

Determination of the Effect of Equivalence Ratio and Pressure on the; ... Finally, all reactant data was entered into STANJAN which was then used to calculate adiabatic flame temperature and the equilibrium composition for equivalence ratios ranging from 0.35 to 2.00 and pressures ranging from 0.01 atm to 1000 atm.

2.5 Equivalence ratio ... To calculate AFR from a given lambda, multiply the measured lambda by the stoichiometric AFR for that fuel. Alternatively, to recover lambda from an AFR, divide AFR by the stoichiometric AFR for that fuel. This last equation is often used as the definition of lambda:
