Method of detecting reference crank angle position in an internal combustion engine at the time of starting same
A method is described for detecting the reference crank angle position in an internal combustion engine during cranking of the engine at the time of starting the engine, which consists of counting the electric pulse signal generated by the first pulser with the counter by referring to the content of the first latch means; resetting, based on the electrical pulse signal generated by the second pulser by referring to the content of the second latch means, the counter and enabling same to count the electric pulse signal again when the reference angle position is not detected until the count of the counter reaches a predetermined count, the predetermined count being equal to a maximum number of electric pulses that can be generated by the first pulser while the rotor makes one revolution; and continuously repeating the counting step and the resetting step until the reference angle position is detected before the count of the counter reaches the predetermined count.
