Formation of Combustion Chamber Deposits during Ignition Delay

摘要

Engine and laboratory experiments are performed to understand theformation of deposits during ignition delay. An experimental Dieselengine allows to observe deposit formation as a global phe- nomenonincluding homogeneous and heterogeneous reactions as well asinteraction between liquid and gaseous phases. A CFR engine is usedto work under the same global conditions but without the liquidphase. A flow reactor enables to investigate the effects of definedand controlled temperatures and fuel/air ratios.
