Advance control device using pickup coil (PICK-UP COIL) of automobile distributor

摘要

1. Technical field to which the design described in the claims belongs;The present invention relates to an advance angle control device using a pick-up coil of a vehicle distributor.;2. Technical challenges that the devise tries to solve.;This is to improve the accuracy and the simplification of the parts, the durability and the accuracy by controlling the lead angle through the strength of the signal inputted to the pickup coil serving to convert the magnetic flux of the magnet to the voltage.;3. The point of solution of design;Among the elements constituting the advance angle control circuit, the constant current source Ie 21 and the resistor R36 22 for controlling the primary current to a current of 6 A are always connected to the battery 2, and the input part V_IN31 are connected to the transistors Q36 and Q37 23 and 24 necessary for the search of the input signal and the transistors Q40 and 25 necessary for outputting the input signals are connected to the output V_OUT32 to control the lead angle.;4. Important Uses of Designs;The advance angle control device using the pick-up coil of the present invention, which is a vehicle distributor, can reduce manufacturing cost to simplify parts, reduce noise due to elimination of mechanical advance control device, improve durability, to be.
