Embodiment Construction

[0019] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] exist figure 1 Shown in is the internal combustion engine 1 located in the engine compartment 9 . The internal combustion engine 1 is a large internal combustion engine, such as a main or auxiliary engine of a ship, or an engine used for power generation and / or heating in a power plant. The internal combustion engine 1 has a turbocharger 2. The turbocharger 2 includes a turbine 2 b rotated by the exhaust gas of the internal combustion engine 1 and a compressor 2 a for pressurizing the intake air of the internal combustion engine 1 . A bypass line 5 with a bypass valve 6 is arranged between the intake duct 13 and the exhaust duct 14 of the internal combustion engine 1 in order to guide excess intake air through the internal combustion engine 1 when required. The intake air of the internal combustion engine 1 is taken from the engine compartment 9 ...

Abstract

A method for operating an internal combustion engine (1) that is located in an engine room (9), in which method the concentration of an exhaust gas component in the intake air is monitored. The invention also concerns an internal combustion engine arrangement.

Description

technical field [0001] The invention relates to a method of operating an internal combustion engine. The invention also relates to an internal combustion engine arrangement. Background technique [0002] Exhaust gas leakage from the exhaust system of an internal combustion engine is a relatively common phenomenon, which leads to various problems. As is the case in engines with selective catalytic reduction, if part of the exhaust gas leaks from the exhaust system before passing through the catalytic converter, this can lead to exceeding emission limits. Another problem caused by exhaust leakage is corrosion problems due to impurities of the exhaust gas entering the intake system of the engine. Especially when using fuels with a high sulfur content (eg heavy fuel oil), exhaust gases in the intake system can cause serious corrosion problems. Exhaust leakage is a particular problem in engines that use high sulfur fuels and inject water in the intake manifold. When sulfur di...
