International Conference on Knocking in Gasoline Engines | 2017

Potential of Direct Water Injection to Reduce Knocking and Increase the Efficiency of Gasoline Engines

Matthias Hunger; Tobias Böcking; Ulrich Walther; Michael Günther; Normann Freisinger; Günter Dr. Karl

Given the need to further reduce CO2 s from passenger cars powered by internal combustion engines and in the light of future tighter exhaust emission regulations, further improvements are necessary to enhance the efficiency and emission behavior of gasoline engines. One major constraint encountered in the gasoline engine is knocking combustion. Its negative effects on efficiency and emission behavior can be counteracted by reducing knock tendency.
