Delivering fuel efficiency and durability, Yanmar Co., Ltd.’s flagship engines for vessels, the EY33 series, is presently under development. The manufacturing phase for the auxiliary engines has already commenced and the development phase for the propulsion engines is on its way towards completion.
Yanmar Co., Ltd. has completed development of a new, reliable dual-fuel engine for vessels that enables the user to switch to and from liquefied natural gas (LNG) and diesel fuel during operation. 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.
