Patent ID: 10224847

Abstract:
Method of operating an engine and electricity generator powered by torque from the engine is provided. The engine has a working-line which is a locus of engine operating points as the engine is throttled. The method includes increasing electrical-load on the generator. Repeatedly performing steps of: (i) detecting the engine working-line position; (ii) determining if the detected working-line position is sufficient for the engine to provide additional torque to power the generator while maintaining engine operation within range of acceptable engine operating conditions relative to the detected working-line position; (iii) when determination at step (ii) is that the engine operating condition is insufficient, modifying engine operational parameters to adjust the working-line position for the engine to provide additional torque while maintaining engine operation within the range of acceptable engine operating conditions; and (iv) increasing electrical-output from the generator by an amount so the engine provides additional torque. Repeating steps until the generator electrical-output matches electrical-load.
