ABSTRACT:
A continuous flow fuel system includes an oxygen sensor for analyzing the exhaust gases of an engine. The output from the oxygen sensor, representing the oxygen content in the exhaust gases, is transmitted to an electronic control module, which in turn controls the output of a fuel pump. The output of the fuel pump provides fuel to maintain a desired fuel/air ratio. The desired fuel/air ratio may be selected by a user of the engine or it may be predetermined and factory-set.
