SYSTEM, METHOD AND COMPUTER READABLE MEDIA FOR CONTROLLING AT LEAST ONE FUEL DELIVERY CHARACTERISTIC DURING A COMBUSTION EVENT WITHIN AN ENGINE
First Claim
1. A system for controlling at least one fuel delivery characteristic during a combustion event within an engine of a locomotive, said system comprising:
- an accumulator having a variable volume, said accumulator is configured to hold fuel at a variable pressure based on said variable volume; and
a combustion chamber coupled to said accumulator;
said variable pressure is varied during said combustion event such that at least one fuel delivery characteristic of said fuel delivered from said accumulator into said combustion chamber is varied during said combustion event.

Abstract
A system is provided for controlling at least one fuel delivery characteristic during a combustion event within an engine. The system includes an accumulator having a variable volume, where the accumulator is configured to hold fuel at a variable pressure based on the variable volume. The system further includes a combustion chamber coupled to the accumulator. The variable volume is varied during the combustion event such that at least one fuel delivery characteristic of the fuel delivered from the accumulator into the combustion chamber is varied during the combustion event. A method and computer readable media are also provided for controlling at least one fuel delivery characteristic during a combustion event within an engine.

22. Computer readable medium containing program instructions for controlling at least one fuel delivery characteristic during a combustion event within an engine, where an accumulator is configured with a variable volume, said accumulator being coupled to a combustion chamber and being configured to hold fuel at a variable pressure based on said variable volume, an injector valve is positioned between said accumulator and said combustion chamber and a controller is coupled to said accumulator and said injector valve, the computer readable medium comprising:
-
a computer program code for varying said position of said injector valve to adjust a variable rate of volumetric flow of fuel from said accumulator to said combustion chamber, and a computer program code for varying said variable volume and variable pressure of fuel within said accumulator to adjust said variable rate of volumetric flow of fuel from said accumulator to said combustion chamber.
