The volume includes selected and reviewed papers from the 3rd Conference on Ignition Systems for Gasoline Engine in Berlin in November 2016. Experts from university and industry discuss in their papers whether classic spark-plug ignition will in future still be able to provide reliable, precise ignition in the light of a wide spread in mixture quality, high exhaust gas recirculation rates and high cylinder pressures. Ignition is the key to further optimizing the gasoline engine.
