Abstract
PURPOSE: To make it possible to diagnose and inspect an engine without contact in a short time, by detecting electric noise,which is generated from the engine and so on, through space and by extracting only required signals.
CONSTITUTION: Receiving part 1 is separated from the generation source such as the engine of a car and is installed, for example, on the floor surface where the car passes in a gasoline stand, and the signal received by this part 1 is amplified and is sent to waveform processing circuit 3 as an analyzable waveform. Waveform processing circuit 3 extracts required components from this signal and substitutes them for a quantitative or numerical signal. Meanwhile, a reference value which is used to detect whether the engine is normal or not is stored in memory circuit 5 previously, and this reference value and the measured value are compared with each other through central control circuit 6 by deciding circuit 7, and the comparison result is displayed on display unit 8 such as a printer, a Braun tube, and a lamp.
