Method and apparatus for inspecting knocking detector

摘要

When a knocking detector mounted on a cylinder block of an engine is inspected, the cylinder block is vibrated by a vibrating unit via a housing connected to the cylinder block, and the performance of the knocking detector is judged based on whether or not a peak value of a voltage variation value serving as a detection value of the knocking detector is below a threshold value which has been set based on a peak value of a test voltage variation value serving as a reference value.
