Amount control has become a major problem in pollution prevention. To control the amount of smoke, it has been proposed to actually measure the amount of smoke in exhaust gas and feed it back to an arithmetic and control device to control fuel injection a4ffl and injection timing. in this case,
The measurement of smoke 1 is based on the induced current generated by passing positively charged smoke along a sensor made of a metal plate, as described in the US 5AE860012 report.

モーク量を測定できない問題がある。[Problems to be Solved by the Invention] However, when a spark plug type sensor is used, for example, the detection sensitivity is reduced due to the small area of the detection part, and the insulation resistance is reduced due to the adhesion of carbon, causing the output to decrease. This has the disadvantage that it becomes inaccurate. In addition, in order to eliminate this carbon adhesion, it is possible to incorporate a spark plug type heater, but because the distance between the electrode and the ground electrode is short, the temperature of the insulator rises when the heater is energized, reducing its resistance. There is a problem that the amount of smoke cannot be measured at the same time as the heater is energized.
