The Significance of Tungsten Points Gap of Distributor - I

In general, the normal gap value of tungsten points of the distributor is between 0.35mm and 0.45mm. If the gap is large than normal gap value of 0.1mm, the petrol consumption of car engine will more than 3% of normal petrol consumption; if smaller than 0.1mm of normal gap value, then the consumption will add 5％of fuel.

The influence factors of the automotive ignition system performance are ignition advance angle, ignition energy and the maximum secondary voltage. If the ignition advance angle is too large or small, the mixture gases would not burn normally after igniting. If the ignition energy is not sufficient, the mixture gases would not properly ignite. If the maximum secondary voltage is low, the spark plugs would not normally flash over. The factors described above will decline the power of engine, rise fuel consumption and dysfunction and other aspects. Therefore, if the gap of tungsten points of distributor is proper, the influence of car ignition advance angle, ignition energy and the maximum secondary voltage to car ignition system will be reduced.
