Embodiment Construction

[0019] The present invention relates to a method for operating an internal combustion engine normally fired with heavy fuel oil combustion in field operation or field mode. Furthermore, the invention relates to a control device for carrying out the method.

[0020] The operation of the internal combustion engine is controlled open-loop or closed-loop based on the operating parameters stored in the control device of the internal combustion engine, wherein the operating parameters for the internal combustion engine stored in the control device are especially when using marine gas oil fuel or DMA fuel for the internal combustion engine (which is also The parameters called MGO fuel) operation apply when in the application mode.

[0021] According to the invention, at least one operating parameter determined by the combustion of the internal combustion engine with DMA fuel is adjusted with a bias, in particular when the internal combustion engine is combusted with HFO fuel. In par...

Abstract

The invention relates to a method and a control device for operating an internal combustion engine. In particular, the present invention relates to a method for operating an internal combustion engine fired with heavy fuel oil or HFO fuel, wherein the operating parameters for the internal combustion engine are applied in particular when applied to the parameters for operation of the internal combustion engine with marine gas oil fuel or DMA fuel , wherein at least one operating parameter determined by combustion of the internal combustion engine with DMA fuel is adjusted with a bias, particularly when the internal combustion engine is combusted with HFO fuel.

Description

technical field [0001] The invention relates to a method for operating an internal combustion engine burning with heavy fuel oil according to the preamble of claim 1 . Furthermore, the invention relates to a control device for operating an internal combustion engine burning with heavy fuel oil. Background technique [0002] It is known from practice that internal combustion engines fired with heavy fuel oil (HFO) in field operation are controlled open-loop or closed-loop based on operating parameters, especially when the internal combustion engine is operating on marine gas oil fuel or DMA fuel (which is also Applies when operating in an application mode called MGO (Marine Gas Oil) fuel. Deviations are realized in the operating performance for DMA fuel applications in particular when the internal combustion engine whose operating parameters are determined by the combustion of the internal combustion engine with DMA fuel is fired in field mode with HFO fuel. therefore, fig...
