Yanmar Partners with Transfluid on New Hybrid System


Japanese diesel engine manufacturer Yanmar has teamed up with the Italian company Transfluid to offer a hybrid system.

The new system is based around Yanmar Marine’s new diesel engine, the 6LY440. This development follows over a year of testing the system, first on a test bench and then a further year on trials at sea.

Unveiled recently the 6LY440 is a 5.8 litre six-cylinder engine rated at 324kW at 3,300rpm with an alternative version, the 6LY400 designed for heavier duty and producing 400 hp. In the hybrid system the Transfluid unit is an HM2000-40 parallel system that comes equipped with a 40kW permanent-magnet electric motor/generator. Incorporated into this is a 2:1 ratio marine transmission gearbox with a low final drive to the propeller shaft. Battery power is included with the package and this comprises a DNV GL type-approved LiFePO4 battery that can produce 19.2kWh of energy at 96V DC.

One of the benefits of this hybrid system is that it can provide a degree of redundancy in single engined boat by offering the capability to operate under electric power independent from the diesel power.
