Industry Database

Yanmar Europe will be present at Europort 2017 in Rotterdam, in Hall 1 Stand 1220, promoting the company’s range of commercial marine products from diesel engines, transmissions to the new small diesel outboard developed by Neander Shark in Germany.

Yanmar’s commercial high speed propulsion engine portfolio includes the mechanical 6AYM engine, an example of which will be on display, and its 12-cylinder stablemate the 12AYM. Also on display will be the 6AYEM high speed engine, which features an electronically controlled common rail fuel system. In addition to these rugged, purpose-built high speed engines for the commercial marine market, Yanmar offers a range of medium speed engines, including the EY33 series, which employs the Miller cycle to achieve low emissions at high power and favourable fuel consumption.

The company’s higher-rated commercial high speed units will be represented by the 6CXBM super light duty engine and the combination of 6LY440 engine with ZF180 transmission, built for light duty commercial applications.

GAS-FUELLED ALTERNATIVES
Yanmar also offers a dual fuel solution, the medium speed 1533kW 6EY26DF, for situations where very low emissions are needed with no sacrifice in power output. Designed for operation on either diesel fuel or liquefied natural gas (LNG), emissions of sulphur oxides (SOx) and particulate matter are cut by 99% when running on LNG, while nitrogen oxides (NOx) are reduced by 85%, and CO2 by 20% to 25%. It is possible to switch between gas and liquid fuels even under full engine loads, while air-fuel ratios are automatically adjusted for optimum operation under different load fluctuations and methane concentrations.

The Yanmar display at Europort will additionally feature the new KM200/300BL gearbox, designed for use with the mechanical 6AYM engine. The mechanical engines are noted for their environmental friendliness and low cost of ownership, and these attributes are matched by the strength, reliability and easy maintenance of the KM200/300 transmissions.

Finally, Yanmar’s Europort exhibit will feature the new D-Torque, the first turbocharged diesel outboard with a dual counter-rotating crankshaft. This cancels out the vibrations normally associated with a twin-cylinder diesel, making the D-Torque smooth in operation and simple to handle. The 50bhp D-Torque is SOLAS certified, and delivers an impressive 111Nm of torque at 2,500 rpm. Added to the low specific fuel consumption and increased safety associated with diesel fuel this means the D-Torque can outperform gasoline four-stroke outboards of far higher horsepower. This unit has been developed in partnership with Neander Motors of Germany.
