Hello together 🙂 In another thread someone threw into the room that the electrode distance in spark plugs would change significantly when they get hot. Can that be that this can cause them to have a particularly small measure in the cold state? If I overwhelm it mathematically, I come to a “growth” of less than 0.1 mm at a temperature increase from 20 °C to 600 °C. That’s very little. Do I miscalculate? This level seems plausible to me, it contradicts. t but the expert’s statement 😉 Are there still “today” – from the year 2000 – vehicles that need electrode distances of less than 0.8 mm? If yes …. why? Modern ignition systems should come with 0.9 … 1.2 mm wonderfully. Greeting Carsten
