Abstract
An engine control apparatus for discriminating each cylinder of an engine comprises a crank angle rotor (M1) having a configuration representing a crank angle of an engine; a crank angle sensor (M2) operatively associated with the crank angle rotor (M1) to generate a crank angle signal in accordance with the configuration of the crank angle rotor (M1). The configuration of the crank angle rotor (M1) includes first and second silent sections. The first silent section is cooperative with the crank angle sensor (M1) to constitute a part (M3) for generating a first level non-pulsation component of the crank angle signal. The second silent section being cooperative with said crank angle sensor to constitute a part (M4) for generating a second level non-pulsation component of the crank angle signal. There is further provided a cam angle rotor (M5) having a configuration representing a cam angle, which is operatively associated with a cam angle sensor (M6) for generating a cam angle signal to provide a plurality of different kinds of signal level sequences with respect to the first and second silent sections of the crank angle rotor. A cylinder discriminating device (M7) discriminates eac…
