Summary:

Variations in air-fuel ratio within a 16-valve port-injection spark-ignition engine have been examined as a consequence of rapid transients in load at constant speed with fuel injection controlled by the production engine-management system and by a custom-built controller. The purpose was to minimize excursions from stoichiometry by the use of a controller to impose an injection strategy, guided by results obtained with the production management system. The strategy involves a model that takes account of manifold filling and the delays in transport of fuel from the injectors to the cylinder. The results show that the excursions in air-fuel ratio from stoichiometry were reduced from more than 25% to 6%
