Abstract
Official abstract text for this publication.
A method of operating an internal combustion engine is provided. An in-cylinder pressure within a cylinder of the engine is determined. A fuel injection pressure from a fuel injector disposed within the cylinder is determined. A ratio of the in-cylinder pressure within the cylinder and the fuel injection pressure is compared to a stored threshold value. The fuel injection pressure is adjusted based upon the comparison of the ratio of the in-cylinder pressure within the cylinder and the fuel injection pressure to the stored threshold value.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of operating an internal combustion engine having a plurality of cylinders, comprising: providing a pressure sensor within a cylinder of the engine for generating a signal representative of the pressure within the cylinder in which the pressure sensor is disposed; providing a fuel injector in communication with the cylinder having variable injection pressure capability; determining a fuel injection pressure of a fuel injector disposed within the…
