Abstract
The purpose of this work was to compare the electrical characteristic of iridium spark plug with the standard spark plug in order to accord with the conditions of general control signal operation of the standard spark plug ignition system. The required voltage and spark duration time are used for analysis. The data of this study were defining by charging time of ignition coil since 0.5-6.0 ms and spark gap at the 0.7, 0.9 and 1.1 mm respectively. That operated under the normal atmosphere. The experimental results indicated that the required voltage of iridium spark plug is lower than the standard spark plug from fully saturated charging time. When it is applied in the general system, the advance angle should be adjusted more advance about 4% and the lower voltage requirement of one lengthens the spark duration, that is not suitable for engine speed more than 24000 rpm.
