However, if ship-owners use an engine-fuel combination with a high sulfur content, the emission limit values can also be met by using additional technology filter systems, scrubbers.
Their different blending ratios make it possible to use marine diesel oil in many different engines. Lighter versions like DMB and RMA 10 are used to power smaller medium- to high-speed marine engines and auxiliary power units, as well as auxiliary engines on very large ships, while the viscous IFO is mainly used in large aggregates.
Lightweight and low-sulfur marine diesel oil is sometimes burned in larger engines as well — whenever an area with stricter emission limits is being crossed. Once outside the area, the ship will switch back to a marine fuel with higher emissions. More information about global maritime regulations and setting emission limit values can be found in the article on Marine Fuels Bunker Fuels.
Lighter marine gasoil MGO and marine diesel oil MDO fuels are significantly more expensive than heavy fuel oil HFO , so that commercial shipping still uses heavy fuel oil for the most part. Heavy fuel oil is mainly used as a marine fuel. The quality of the residual fuel depends on the quality of the crude oil.
To achieve various specifications and quality levels, these residual fuels are blended with lighter fuels such as marine gasoil or marine diesel oil. This information is used to improve the website.

But older steam locomotives and oil -fired power plants also generate energy from heavy fuel oil s. Heavy fuel oil is a residual fuel incurred during the distillation of crude oil. The quality of the residual fuel depends on the quality of the crude oil used in the refinery. To achieve various specifications and quality levels, these residual fuel s are blended with lighter fuel s such as marine gasoil or marine diesel oil.
The resulting blends are also referred to as intermediate fuel oils IFO or marine diesel oil. They are classified and named according to their viscosity. If there is a predominance of heavy fuel oil in a blend, it is assigned to the heavy fuel oil category. As these are blends of heavy fuel oil and lighter fuel s, they can also be referred to as a heavy marine diesel oil. The ISO international standard divides marine fuel s into distillate fuel s and residual fuel s.
