Hybrid vehicle oil leak observation circuit

Hybrid vehicle oil leak observation circuit belongs to the hybrid vehicle control technology field, the utility model discloses a solve the whether problem of mode incomparable to in time discoveringoil leak hidden danger of oil leak of the daily detection car of driver. The utility model discloses an oil leak collector unit 1, NE555 time -base integrated circuit, KD 9561 pronunciation chip, triode VT1~VT3, electrolytic capacitor C1, electric capacity C2, resistance R1~R5, diode D1, auxiliary relay K and loudspeaker BL, when not having machine oil to get into the linker, the liquid between the electrode terminals is the running water completely, is conducting state, and follow -up observation circuit does not trigger audio alert, in case the oil leak, the machine oil that gets into the linker forms the water oil separating layer with original running water, the machine oil on -conductive, and liquid is no longer electrically conductive between two electrode terminals promptly, triggers subsequent observation
