Japanese diesel engine manufacturer Yanmar has introduced its new medium speed 1533kW 6EY26DF dual fuel engine at Europort 2017.

The 6EY26DF is the first of a whole new range of dual fuel solutions from Yanmar, based on its existing diesel range, which will be hitting the market this year and next. Due to the power constraints of the dual fuel technology, power outputs of the dual fuel models will be at the low end of the published power range for the equivalent pure diesel model.

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 new International Maritime Organization (IMO) Tier 3 regulations, introduced in January this year, require an 80% reduction of nitrogen oxides (NOx) emissions from the Tier 1 levels, and a 20% improvement of CO2 emissions by 2020; representing an annual tightening of emissions for vessels. With the flexibility to operate using both LNG which offers superior environmental benefits and easy to obtain diesel fuels, the dual-fuel engine has drawn considerable attention in recent years as a solution that easily passes the demanding Tier 3 emissions controls.

While advanced electronic control is typically required for utilization of two different fuel types, the EY26DF is said to ‘employ high-precision air flow technology that optimizes combustion conditions delivering stability and reliability when in operation’.

Ignition with the micro-pilot injection system, when in gas mode, is claimed to be as effective as a diesel engine. According to Yanmar’s published figures, compared to the same-class EY26 diesel engine, the 6EY26DF delivers 84% NOx, 25% CO2, and 99% Sox and PM reductions, thereby meeting IMO Tier 3 standards.

According to a Yanmar spokesman at Europort, the company is now working hard on a high speed dual fuel engine to add to the range.
