SYSTEM, METHOD, AND APPARATUS FOR FUEL INJECTION CONTROL

摘要

A method includes determining a stored injection relationship that includes a number of fuel performance parameters. In one form the fuel performance parameters are related to a particular shape, and may be related to a particular operating condition. The method includes determining a fuel performance outcome during a fuel injection event, and updating the stored injection relationship in response to the fuel performance outcome. The fuel performance outcome can be an injected fuel quantity.

1. An apparatus comprising:
a fuel event controller configured for use with a fuel injector having an injector configuration modeled by a rate shape characteristic that includes one or more of an opening rate shape, a start of injection delay, a peak rate, a closing rate shape, an end of injection delay, and an injection duration, the fuel event controller structured to determine one or more of the rate shape characteristics corresponding to the injector configuration by operating upon (1) a fuel value corresponding to an estimate of the injected fuel quantity delivered from the fuel injector; and (2) a relationship which is dictated by the injector configuration and that relates the estimate of the injected fuel quantity to the one or more of the rate shape characteristics.
