Abstract
According to some embodiments, the present disclosure may relate to a system including a gaseous fuel consuming engine operating at an air to fuel ratio (AFR) and including a throttle valve controlling a speed of engine, and an engine controller coupled to the engine. The engine controller may be configured to obtain the speed of the engine and obtain the AFR of the engine. The engine controller may also be configured to, based on a transient event affecting the engine, coordinate modification of both the throttle valve to change the speed of the engine and trim valve to change the AFR of the engine to maintain at least one of the speed and the AFR of the engine within a threshold deviance.
