METHOD AND SYSTEM FOR AIR FUEL RATIO CONTROL
Document Type and Number:
WIPO Patent Application WO/2012/167047
Kind Code:
A3
Abstract:
Air fuel ratio control for an engine driving an electrical power generation system is provided. Engine speed of an engine driving an electrical power generation system is adjusted in response to an air fuel ratio while maintaining a power transmitted from the engine to the electrical power generation system. The adjustment comprises adjusting generator torque and engine fuelling, thereby changing the engine operating point without changing its power output.
