Abstract
Official abstract text for this publication.
Various systems and methods are described for controlling pre-ignition in a boosted engine in a newly manufactured vehicle. One method comprises, during a pre-delivery phase of the vehicle, operating the boosted engine in a pre-delivery calibration with a first, higher enrichment, in response to a pre-ignition event. The pre-delivery calibration is deactivated during a post-delivery phase and the boosted engine is operated with a second, lower enrichment in response to a pre-ignition event.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method, comprising: during a pre-delivery phase of a vehicle including an engine, operating the engine with a first setting for a parameter in a pre-delivery calibration; adjusting the first setting of the parameter responsive to pre-ignition; and during a post-delivery phase of the vehicle, operating the engine with a second setting for the parameter in a post-delivery calibration. 2. The method of claim 1 , wherein…
