Wärtsilä Methanol-Diesel retrofit solution

On-engine scope is limited to exchange of cylinder heads,fuel injectors and fuel plungers in existing fuel pumps

A common rail system for methanol injection will be addedon the engine

In addition to the Engine related conversion includes the conversion kit a stand-alone high pressure methanol pumpwith belonging oil unit for supply of sealing oil and control oilto the fuel - beside an update of the automation system.injectors.

Tests on Methanol – Initial testing of Wärtsilä MD concept

Optimal heat release Lower Exhaust Temperatre

Reduced NOx Same efficiency as diesel

CO, THC acceptable ( < 1 g/kWh)Formaldehyde emissions low ~ much below TA-luftNo Formic acid detected in exhaust gases

Engine: Wärtsilä Vasa 32
