• Existing ships: Tier I to be applied for vessels constructed between 1990 and 2000 (diesel engines > 5000 kW and > 90 liters / cylinder). Some exemptions are considered

Wärtsilä DF / SG engine meet already Tier III

Applies to both new buildings and existing ships !

Low Natural Gas Emissions

– 25-30% lower CO2• Low Carbon to Hydrogen ratio of fuel

– 85% lower NOX• Lean burn concept (high air-fuel ratio)

– No SOX emissions• Sulphur is removed from fuel when liquefied

– 50% lower PM Particulates• Particulates vary across operating range

– No visible smoke

– No sludge deposits extends engine lifeULTRA CLEAN COMBUSTION

Gas engine technologies

Gas-diesel (GD) engines:Runs on various gas / diesel mixtures or alternatively on diesel.Combustion of gas, diesel and air mixture in Diesel cycle.

High-pressure gas injection.

Dual-fuel (DF) engines:Runs on gas with 1% diesel (gas mode) or alternatively on diesel (diesel mode).Combustion of gas and air mixture in Otto cycle, triggered by pilot diesel injection (gas mode), or alternatively combustion of diesel and air mixture in Diesel cycle (diesel mode).Low-pressure gas admission.

Spark-ignition gas (SG) engines:Runs only on gas.

Combustion of gas and air mixture in Otto cycle, triggered by spark plug ignition.

Low-pressure gas admission.
