Fuel control system and method for improved response to feedback from an exhaust system |
摘要 |
An engine control system includes a proportional correction module and a variable proportional gain determination module. The proportional correction module generates a proportional correction for a fuel command to an engine based on a variable proportional gain and a difference between expected and measured amounts of oxygen in exhaust gas produced by the engine. The variable proportional gain determination module determines the variable proportional gain based on a nominal gain and an amount of time since a polarity of the difference has changed, wherein the nominal gain is based on engine operating parameters. |
