Marine Engine
S12A2-MPTAW
General information
The S12A2-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.
Benefits
