Abstract
The fuel transfer characteristics of the intake port of a fuel-injected spark ignition engine have been determined for engine warm-up conditions following cold starts at temperature down to -30°C and extending to fully-warm states, using a method based upon perturbing fuel injection rate and recording AFR response. The variation of τ and x parameters over a range of temperatures, engine speeds, AFR, and engine loads has been evaluated. Temperature and speed have greatest influence, AFR and load effects are small. Application of the data to define transient fuel compensation requirements has been examined.
