Smokeless gas start with the Wartsila 46DF engine | Wärtsilä

Watch a LIVE video of a pilot check of the Wartsila 46DF (dual fuel) engine being started in gas mode and showing NO visibility of smoke emissions. There are no low load restrictions in gas mode operation, stable operation is achieved through innovative gas and pilot fuel injections and it can be operated in gas mode from idling to 100% load with no time restriction. #WartsilaKnowsGas

Great minds contributed for a cleaner Mother Earth.

wow excellent. Save on fuel, while protecting the environment...you don't see that everyday!

If the funnel open to sky vertically , duruning running how to prevent water ingress

[@user-xg5ds1cp3r]

Fascinating

[@electric7487]

What is the V angle on the 46F and 46DF?

[@hosseinhaddad2458]

Can we use these fuel instead of diesel , the engine is of the same kind

[@wartsilacorp]

Yes, this is a Dual-Fuel engine which can use both diesel and LNG as fuel sources.

[@dennisschoenaurer4152]

Last I checked you would still need a catalytic converter and particulate filter to make it be a Continuous running engine

[@bartosz7170]

Is that hot or cold start?

[@PeaceMah]

For sure a hot start.

[@user-jt8hi2eh9h]

What is it "cold" start?

[@bartosz7170]

@@user-jt8hi2eh9hcold state means that all the fluids and materials have ambient temperature at the beginning of the start

[@roualdeetlefs4745]

I know that there are street legal methanol burning engines in the United States. Can these engines also be modified to run on methanol ? If methanol burning is indeed possible, how difficult will it be to raise the compression ratio of these engines, to take advantage of methanol's higher octane rating ?

[@gailgrove]

This is a diesel engine, running on natural gas. It already has a high compression ratio being a diesel. However I don't see any practical reason to run an engine this size on methanol, it'd burn thousands of gallons an hour at full throttle.

[@user-jt8hi2eh9h]

Methanol are very dangerous for crew due to its poison.

[@gerardhernandez7528]

The titanic 2 will have that kind of engine

[@mgiles5507]

Bet you can't do that on HFO

[@wartsilacorp]

For that, we have scrubbers! th-cam.com/video/E5Zi-6vd5ko/w-d-xo.html

@@wartsilacorp how are these normally operated - start on CNG revaporized and then when at temperature shift to *FO and is that a flash cut or does the mix changed over a period of many seconds/minutes ? Thanks.
