摘要： A method for operating a self ignition internal combustion engine (ICE) with a low cetane fuel such as alternative fuels, for example pyrolysis oil, as well as an ICE are disclosed. To reach self ignition conditions one may provide the internal combustion engine to have a compression ratio of at least 17:1, for example, 18:1 (step 100). Moreover, one may load a combustion chamber of the internal combustion engine with charge air having a minimal temperature in the range of 340 degrees K to 360 degrees K (step 200) and inject the low cetane fuel at an injection angle of a piston of the internal combustion engine within the range of 20° to 10°, for example between 17.5° to 11° before top dead center into the charge air (step 300), thereby forming a low cetane fuel-charge air mixture. Compressing the low cetane fuel-charge air mixture further during the combustion cycle may result in a compression end temperature of at least 1000 K, allowing self ignition of the low cetane fuel.

摘要： For exhaust gas recirculation in internal combustion engines operating, for example, with low sulphur marine diesel oil, an exhaust gas cooler with a cooling unit may be applied that uses a liquid injection system to maintain clean and/or clean a cooling surface of the cooling unit. The liquid injection system may provide liquid into an exhaust gas passage upstream of and or along a condensation starting region the cooling surface, thereby reducing the formation of films and deposits from particulate matter and condensing liquid of an evaporated liquid within the exhaust gas such as sulphuric acid and/or water, as those deposits could otherwise at least partially block the exhaust gas cooler.
