First Claim
Patent Images
1. A method for determining fuel limits for an engine comprising the steps of:
- measuring an actual fuel value for the engine;
selecting a plurality of engine speed points; and
calculating respective static fuel limit points for the engine speed points utilizing the actual fuel value;
wherein the static fuel limit points define and limit a rated power of the engine.

Abstract
A method of determining fuel limits for an engine includes measuring an actual fuel value for the engine and creating a plurality of engine speed points. The method further includes calculating respective static fuel limit points for each of the engine speed points utilizing the actual fuel value. The static fuel limit points define and limit a rated power of the engine.
