  • Device for obtaining signals for the control unit of an electronic fuel injection system
    Patent number: 4051818
    Abstract: A device modifies the signals for the control unit of an electronic fuel injection system of an internal combustion engine in order to reduce lengthwise vehicle vibrations. The signals are derived from a tachometer that measures the engine speed and a gauge that measures the air flow supply to the engine. The device dampens the a.c. components in the signal either symmetrically or asymmetrically. This device can be in the form of a passive RC circuit with diodes to determine the operating points or it can be an active circuit.
