The invention proposes a damping
resistor. The damping
resistor comprises a
Bakelite shell, a
resistor, a bolt, a cable core, a high-
voltage line, a hole, a spring, a cover cup, a fastening corner bracket and a fastening element, wherein the bolt is arranged in the
Bakelite shell, the hole is formed on the left side of the bolt, the resistor and the spring are arranged in the hole, the resistor is a carbon resistor, the cable core is arranged on the right side of the bolt, the outer surface of the cable core is coated with the high-
voltage line, the cover cup is fixedly arranged on the left side of the
Bakelite shell, and the fastening element passes through the fastening corner bracket to make the cover cup fixed on the fastening corner bracket. In the damping resistor, the damping resistor is connected in series in a high-
voltage circuit of an
ignition system to reduce high-
frequency oscillation generated by
electric spark, and thus, the interference intensity of electromagnetic wave is reduced; and since the damping resistor is arranged on a high-voltage wire lead-out end of an
ignition coil, is formed by burning a
nickel chrome
lead alloy filament and is equivalent to a combination of an
inductor, a
capacitor and a resistor, the effect of suppressing the electromagnetic wave is ideal.
