I would like know about high speed diesel engine in marine application.
How do we use high speed diesel engine in marine field?
Could anyone tell me about website addresses for high speed diesel engine?

I think you might have more success by narrowing your questions to a specific topic. I am not sure what you are asking of us, since every type of vessel has a different needs for power.

On websites then just goggle for wärtsilä, volvo penta, cummins, caterpillar to name a few.

otherwise I have to agree with The Dieselduck, specify please...
