Abstract
A method for determining the proper fueling of an internal combustion engine when nitrous oxide is being injected into the air intake of the engine determines an equivalent air per cycle (APCequiv) by calculating the effect of both the air and the nitrous oxide on the oxygen content of the gas stream flowing into the cylinders of the engine. After calculating the equivalent air per cylinder magnitude, the fuel per cylinder (FPC) is calculated as a function of the stoichiometric air fuel ratio and an equivalence ratio that modifies the stoichiometric air/fuel ratio.
