tachometer spark plug wire

• 2022-06-28

The tachometer spark plug wire is the wire that transmits the high voltage generated by the ignition coil to the spark plug, which is also called cylinder line, cylinder line, fire line and high-voltage ignition line. It is to distribute the ignition sequence, which can transfer the high-pressure fire distributed by the distributor to the spark plug, make the ignition and combustion in the cylinder work, and drive the engine to rotate.

Cylinder line is an indispensable part of the traditional ignition system. It is the medium for the ignition coil to transfer its energy to the spark plug. The cylinder line is divided into four parts: conductive material, insulating rubber, ignition coil connector and spark plug connector.

The automobile cylinder line adopts silica gel technology, with high temperature resistance of -40 ° C to +220 ° C and high voltage of 35kV; The wire core adopts silica gel conductor, with stable resistance and superior conductivity; The wire body is multi-layer reinforced, and its service life is longer.

From the internal structure, the high-voltage ignition wire can be divided into single core, three core, four core and five core. In principle, the more cores, the lower the resistance, the higher the ignition intensity and the more expensive the price. However, there are too many cores and the current is too strong. If special packaging and shielding materials are not used, electromagnetic interference will be generated, making the on-board audio and on-board computer unable to work normally due to electromagnetic interference.

When the car is cold started, check the working conditions of the spark plug, high-voltage wire and ignition coil once the tachometer is up and down. Poor operation of the ignition system and poor spark plug ignition will also lead to this kind of fault phenomenon. The solution is to check the spark plug for excessive carbon deposition and replace the spark plug.

Unstable oil pressure or poor oil quality. If you have cleaned the engine carbon deposit, washed the throttle valve, replaced the oil pad and spark plug, and still find that the body shakes when idling, it is recommended to go to the 4S store to check whether the fuel supply pressure and the intake pressure sensor are normal. If the fuel supply pressure of the fuel pump is abnormal, or the intake pressure sensor has the wrong value and poor operation, the body shakes. The solution is to check the oil pressure and replace the components if necessary. Jitter may also occur when the oil quality is poor. It is recommended to replace the fuel inspection at the gas station.
