The Reasons of Tungsten Contacts Ablation of Car Distributor – IV

The reasons of tungsten contacts ablation of car distributor as shown below:

7. The spring of tungsten contacts’ arm of distributor is too soft. If the tungsten contacts’ arm spring is too soft, flashover situation is still normal when the car running at low speeds; but when the car is working at a high speed, because of the high speed inertia effect of the engine, the closure of tungsten contacts is more slower, which appears off-fire phenomenon, so the car's exhaust pipe will issue a "sudden, sudden, sudden" irregular sound. Moreover, tungsten contacts after closure will appear rebound phenomenon, and the phenomenon make spark more vulnerable to emerge, and eventually tungsten contacts will be ablated.

8. Bad ground capacitor. When test fire, due to the spark is weak, and flashover distance is shorter, so the engine will be more normal when it is operating at no load. However, the car in working process is of instability, which would make carburetor appearing tempering phenomenon, and the exhaust pipe sometimes shooting when the engine is working at high speeds, make the arcs of tungsten contacts increase, eventually ablate tungsten contacts.
