Abstract
An engine controller regulates fuel flow to an internal combustion engine based on sensed air flow and sensed engine operational parameters. The engine controller includes a speed sensor, a power sensor, an airflow meter and a controller unit. The speed sensor generates an engine speed signal representative of sensed engine speed, the power sensor generates an output power signal representative of sensed engine output power and the airflow meter generates an actual airflow signal representative of sensed airflow. The controller unit is responsive to the engine speed signal, the output power signal and the actual airflow signal and develops a command signal for an air-fuel mixer.
