Method and system for improving fuel economy and controlling engine emissions

摘要

An engine controller for an engine configured for improving fuel economy and decreasing negative emission characteristics. The engine controller is operatively coupled to the engine and configured to intercept angular position sensor signals and generate an adjustable angular position sensor signal and output the adjusted signal to the engine control module operatively coupled to the engine. The engine control module is configured to control the fuel injector for the engine and is responsive to the adjusted angular position sensor signal. The engine controller is operatively coupled to a hydrogen injection module configured to deliver hydrogen to the engine in conjunction with the operation of the engine controller. According to another aspect, the engine controller is configured to intercept valve actuator signals from the engine control module intended to control variable valve actuators in the engine. The engine controller includes a module configured to adjust or modify the valve actuator signals in response to changes in the angular position of the engine and output the adjusted valve actuator signals to control the variable valve actuators in the engine.
