とができる。In the case of a four-cylinder engine (2), the torque pulsation signal d is output in the order of the first cylinder, the third cylinder, the fourth cylinder, and the second cylinder as shown in FIG. Therefore, this pulsating signal d and calm 1
According to pulse a, first, the first cylinder is distinguished. and,
Subsequently, the Nxh 3 , Na 4 , and Nch 2 cylinders are sequentially distinguished, and signals for each cylinder are outputted from the cylinder discrimination output means (a). That is, by doing this, there is no need to take a TDC mark for each test engine as in the past, which saves time and effort, and it is possible to obtain cylinder-specific signals as information without using a phase detector.
