THE EFFECT OF HIGH-RESISTANCE IGNITION CABLE ON THE EROSION OF SPARK-PLUG ELECTRODES

摘要

Engine tests were made using high-resistance ignition cable on an air-cooled five-cylinder radial auxiliary power plant operated at low mean effective pressure to determine the effects such cattle would have on erosion of spark-plug electrodes. The brief tests showed that erosion was reduced about 70 percent when high-resistance ignition cable was need in place of standard cable on an engine equipped with nonresistor spark plugs and that the reduction was approximately the same when spark plugs with internal resistors were used with the standard cable.
