ABSTRACT:
A fuel controller for an internal combustion engine has an air temperature sensor in an air intake pipe and a cylinder pressure sensor which measures the pressure within a cylinder of the engine during a compression stroke. A control unit calculates the air quantity in each cylinder based on the measured intake air pressure and cylinder pressure and controls the fuel injectors of the engine so as to obtain a desired air-fuel ratio.
