    摘要: Dual-Fuel marine combustion engine (1) , preferably low pressure dual fuel engine, in particular two-stroke dual fuel low speed engine, and corresponding method and retrofit-kit comprising at least one combustion chamber (2) for ignition of a gas-air or liquid fuel-air mixture. The engine comprises an air inlet (3) into the combustion chamber (2) and an exhaust outlet (4) out of the combustion chamber (2). Furthermore, the engine (1) comprises a gas mode of operation and a liquid fuel mode of operation wherein an inert gas inlet valve (5) is controllable by a control unit (6), such that an inert gas is introducible into the at least one combustion chamber (2), preferably through the air inlet (3), depending on predefined combustion states, in order to reduce the occurrence of pre-ignition.
