DIAGNOSING DEVICE OF AUTOMOBILE ENGINE

摘要

PURPOSE:To enable a safe use of diagnosing device by connecting an engine signal detecting device and a controlling device for engine diagnosing via an electrically insulated signal transmitted means. CONSTITUTION:In case of installing an automobile engine diagnosing device at service station, an oil supplying position A of an automobile 3 is determined by an island 2 providing a fixed type oil feeder 1, but a detecting device 4 to detect an engine driving signal of an automobile 3 is provided to the fuel supplying position A. The detecting device 4 is provided by winding a receiving wire 4a swirling in square type of 1cm width using a braided wire with making one side in the size of about 40cm and allowing the diagonal line to coincide with the advancing direction of the automobile 3. The outside is molded by epoxy resin 4b and the receiving wire 4a of the detecting device 4 is connected to the engine spark detecting circuit of the controlling device via a signal transmitting means 12 by a co-axial shielding cable 6 via socket 5.
