SFI SYSTEM


  1. CONSTRUCTION


    1. A Magnetic Resistance Element (MRE) type crank position sensor is used to detect the engine speed and crankshaft angle.

    2. The crank angle sensor plate (timing rotor) of the crankshaft consists of 34 teeth with 2 teeth missing. The crank position sensor outputs a crank rotation signal every 10°, and the change of the signal due to the missing teeth is used to determine top-dead-center.
