Wärtsilä has introduced a new methane slip reduction solution for its Wärtsilä 50DF dual-fuel engine. The new technology converts Wärtsilä 50DF dual-fuel (DF) engines to spark gas (SG) operation. This enables a more optimized combustion process, improving efficiency and lowering methane emissions.

While operating on LNG, the new spark gas conversion for the 50DF is designed to reduce methane emissions by up to 75% more than the standard 50DF engine.

The new methane slip reduction solution minimizes methane emissions by introducing an electrically controlled pre-combustion chamber valve for a more optimized combustion process. The estimated result is that, on an IMO weighted (E2-cycle) average, the new solution reduces methane emissions down to 1.1% of fuel use.

“The use of LNG and cutting methane emissions is one of the most effective ways to decrease overall
