Abstract

Official abstract text for this publication.

Methods and systems for adjusting fuel injection of an internal combustion engine are disclosed. In one example, a change in fuel pressure is scheduled when a number of pilot fuel injections provided by a fuel injector to a cylinder transitions from a first number during a first engine cycle to a second number during a second engine cycle. The methods and systems may reduce engine emissions and improve engine noise characteristics.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for fueling an engine, comprising: supplying fuel to a cylinder based on a pressure output from a first table expressing fuel pressure as a function of a first number of pilot fuel injections supplied to the cylinder in a first mode; supplying fuel to the cylinder based on a pressure output from a second table expressing fuel pressure as a function of a second number of pilot fuel injections supplied to the cylinder in a second mode; and c…
