Internal combustion engine, method for cleaning exhaust from an internal combustion engine and method for refitting an internal combustion engine

The invention provides an internal combustion engine, a method for cleaning exhaust from the internal combustion engine and a method for refitting the internal combustion engine. An Internal combustion engine (1), preferably a two-stroke engine for a large vessel, comprises an exhaust outlet (2) for disposing of exhaust out of a combustion chamber and an air inlet (3) for introducing air into the combustion chamber. At least one turbocharger (4) is connected to the exhaust outlet (2) by an exhaust passage (5) wherein a particulate filter device (6) is arranged downstream the exhaust outlet (2) on the high pressure side of the turbocharger, in particular of a turbine of the turbocharger, preferably in the exhaust passage (5). 本发明提供内燃机、清洁内燃机排气的方法和改装内燃机的方法。种内燃机(1)，优选为用于大型船舶的二冲程发动机，包括用于将排气从燃烧室排出的排气出口(2)，和用于将空气引入燃烧室和空气入口(3)。至少个涡轮增压器(4)通过排气通道(5)连接至排气出口(2)，其中，颗粒过滤器装置(6)在涡轮增压器的高压侧上，特别是涡轮增压器的涡轮侧，布置在排气出口(2)的下游，优选布置在排气通道(5)中。
