Abstract:
1. A method for inspecting an ignition device for an internal combustion engine having a combustion chamber, the device including an ignition plug for discharging in the combustion chamber, an ignition coil for supplying a high voltage to the ignition plug, and a cylindrical ignition device housing for housing the ignition plug and the ignition coil, the ignition device further including a ground electrode that is fixed to the ignition device housing, and a portion of the ignition device housing functions as an outer peripheral core of the ignition coil, wherein the device is inspected by measuring a voltage generated in the ignition coil, comprising: preparing a cylindrical inspection housing for an inspection of the ignition device; inserting the ignition coil in the inspection housing; and measuring the voltage generated in the ignition coil that is housed in the inspection housing, wherein the inspection housing functions as a housing substituted for the ignition device housing and an outer peripheral core of the ignition coil during the inspection, and the measuring is performed using the inspection housing that differs from the ignition device housing especially in that a ground electrode is not fixed to the inspection housing.
