Abstract

A method of operating an internal combustion engine is provided. An air/fuel ratio of the internal combustion engine is determined. At least one of a fuel injection quantity and an intake air flow is adjusted to provide an air/fuel ratio between about 15 and about 18. A compression ratio within a cylinder of the engine is determined. Droplet size of fuel provided by a fuel injector is adjusted based upon the compression ratio determined within the cylinder of the engine.

Claims (12)

1. A method of operating an internal combustion engine having a plurality of cylinders, comprising:

providing air and fuel to a cylinder of the engine at an air/fuel ratio between about 15 and about 18;

determining a compression ratio within the engine cylinder;

the fuel being supplied by a fuel injector; and

adjusting the droplet size of the fuel provided by the fuel injector based at least in part upon the compression ratio determined within the cylinder of the engine.

2. A method in accordance with claim 1 in which providing air and fuel to a cylinder of the engine at an air/fuel ratio between about 15 and about 18 comprises adjusting at least one of a fuel injection quantity and an intake air flow.

3. A method in accordance with claim 1 in which the engine has a variable compression ratio.

4. A method of operating an internal combustion engine, comprising:

determining an air/fuel ratio of an internal combustion engine;

adjusting at least one of a fuel injection quantity and an intake air flow to provide an air/fuel ratio between about 15 and about 18;

determining an in-cylinder pressure within a cylinder of the engine;

adjusting droplet size of fuel provided by a fuel injector based upon the in-cylinder pressure determined within the cylinder of the engine.
