Locomotive engine multi-fuel control system and method
First Claim
Patent Images
1. A method, comprising:
- operating an engine by combusting in the engine a plurality of different fuels available to the engine, alone or in combination with one another;
based on sensed operational data of the engine during combustion, determining whether to control the engine to reduce specific fuel consumption of the plurality of different fuels as combusted;
upon determining to control the engine to reduce the specific fuel consumption, controlling a first parameter set of the engine to reduce the specific fuel consumption of the plurality of different fuels as combusted; and
controlling a second parameter set of the engine to avoid exceeding one or more acceptable limits associated with the engine during combustion of the plurality of different fuels.

Abstract
A method, in certain embodiments, includes controlling a first parameter set (e.g., fuel injection timing, engine speed, etc.) of an engine to reduce specific fuel consumption to account for a plurality of different fuels alone or in combination with one another. The method also may include controlling a second parameter set (e.g., engine duration, engine speed, manifold air pressure, fuel supply temperature, fuel supply pressure, etc.) of the engine to reduce the possibility of exceeding design limits associated with the engine to account for the plurality of different fuels alone or in combination with one another.
