General information

The S6A3-(T2)MPTK engine is designed and built in Japan. 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. Utilizing a long-stroke block with in-house MHI turbocharger technology, we have managed to maintain the footprint of our lower output engines, while substantially increasing the power output. Its maintenance is easy as each cylinder has its own cylinder head. We offer a complete package, including a built-up heat exchanger, a seawater pump and panels for a compact design, ensuring easy installation and maintenance.
