  "textContent": "In a cylinder discrimination device in an engine, a crank angle signal is output for each unit crank angle in synchronization with the rotation of a crankshaft in the engine, different numbers of cylinder discrimination signals are output corresponding to cylinders to be discriminated during a predetermined crank angle period, and a count value of the crank angle signals to be output after a cranking start is held each time the cylinder discrimination signal is output. By comparing the count value of the number of the crank angle signal outputs at a first cylinder discrimination timing with the past count values, to detect the number of the cylinder discrimination signals output during the predetermined crank angle period, and first cylinder discrimination after the cranking start is performed based on the number of the detected cylinder discrimination signals.",
