ABSTRACT:
An aircraft piston engine control system according to the present invention has a fuel supply passage for supplying fuel to the engine. A fuel regulation device is arranged in the fuel supply passage, is linked to a throttle lever, and regulates an amount of fuel so as to realize a first air-fuel ratio which is more rich than the stoichiometric air-fuel ratio. A fuel decreasing passage is connected to the fuel supply passage between the fuel regulation device and the engine. A fuel decreasing device is arranged in the fuel decreasing passage, and decreases an amount of fuel regulated by the fuel regulation device so as to realize an optimum air-fuel ratio according to the current engine operating condition.
