Marine Engine
S12R-MPTAW
General information
The S12R-MPTAW engine is designed and built in Japan and finished to customer specifications in France in order to deliver performance and reliability. From the combustion chamber design to the fuel injection technology, to the turbocharger and the advanced cooling system. Everything has been perfectly balanced to provide highly reliable operation, optimum fuel consumption and minimized installation footprint. Its maintenance is easy as each cylinder has its own cylinder head, and the engine has large inspection covers on the crankcase. This strength and reliability are ideally suited for propulsion for various types of vessels.
IMO Tier III
To meet the IMO Tier III environmental regulations we use an SCR system. An SCR system is a system that reduces NOx emissions from the engine exhaust gases. The GESAB SCR system design and settings have been fully optimized and tested (according to scheme A) to the Mitsubishi Marine Engines and Generator Sets to be cost-effective as well as meeting our quality requirements and the IMO Tier III environmental regulations.
