Abstract
Methods for determining rate of fuel flow to a combustion engine is disclosed. The fuel flow rate determination is made by measuring a pertubation in air-to-fuel-flow ratio to the engine, or in the volumetric concentration of a gaseous test species in the exhaust, after adding a known amount of a test substance to the air flow intake to the engine, or to the exhaust from the engine, respectively. The desired fuel flow rate is calculated from the measured parameters.
