Following detection of an acceleration enrichment condition in a fuel injection system of the type having a hot-wire air quantity sensor, a plurality of initial enrichment injections (RTIBA) replace the normal injections (ti) based on engine load, these initial injections being applied for the next X 180 DEG or 360 DEG crankshaft rotations and being of a length which is independent of engine load (TL) but being dependent upon engine variables (such as engine speed n, hot-wire voltage ULHM and change in hot-wire voltage DELTA ULHM) which are available at the instant of detection of the acceleration enrichment requirement. Following completion of the X 180 DEG or 360 DEG crankshaft rotations, or if the normally calculated injection period (ti) based on engine load has become greater than the length of the initial injections (RTIBA), then the normally calculated value (ti) is again adopted. The length of the initial injection or injections (RTIBA), dependent upon the engine temperature as well as on the "load substitute variables" of the speed n, hot-wire voltage ULHM, change in hot wire voltage DELTA ULHM, are determined from stored look-up tables. |
