2.1.7.4. Spark plug

The iridic spark plug is used. The central electrode has diameter of 0.6 mm and is made of an iridium alloy.

Fig. 2.71. Spark plug: 1–iridium alloy; 2–platinum tip

Thinner central electrode allowed to reduce an electric discharge and to improve ignition characteristics. that, in turn, allowed to provide steady performance data under all traffic conditions and it is essential to improve fuel profitability (fig. 2.71).
