Title:
CONTROL DEVICE OF INTERNAL-COMBUSTION ENGINE, AND SHIP PROVIDED WITH SAME, AND METHOD OF OPERATING INTERNAL-COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2016/136001
Kind Code:
A1
Abstract:
The present invention relates to an internal-combustion engine, and the objective of the invention is to make it possible to suppress NOx emissions, without using an additional device, in marine areas having strengthened exhaust emission regulations, while making it possible to maintain the output of the engine in other marine areas. This control device is provided with: a combustion system selecting means (44) capable of selecting, while an internal-combustion engine is running, at least a fuel gas diffusion combustion system and a fuel gas premixed combustion system; a fuel injection control means (46) which controls fuel injection in such a way as to achieve a fuel injection mode corresponding to the selected combustion system; and an actual compression ratio changing means (48) which changes the actual compression ratio on the basis of the selected combustion system. If the combustion system is switched to the fuel gas premixed combustion system while the internal-combustion engine is running, the actual compression ratio changing means (48) changes the actual compression ratio to a low compression ratio, and if the combustion system is switched to the fuel gas diffusion combustion system while the internal-combustion engine is running, the actual compression ratio changing means (48) changes the actual compression ratio to a high compression ratio.
