Title:
最適な全開スロットル空燃比制御
Document Type and Number:
Japanese Patent JP4025278
Kind Code:
B2
Abstract:
This feature of the present invention comprises a method and apparatus which uses an ionization signal to optimize the air to fuel ratio AFR of the combustion mixture when the engine is operated at wide open throttle (WOT). This feature of the present invention optimizes the air to fuel ratio AFR on-line using the relationship between an air to fuel ratio AFR index CAFR and the air to fuel ratio AFR. In a preferred embodiment, the real-time control strategy adjusts the engine air to fuel ratio AFR based upon an air to fuel ratio AFR gradient parameter.
