What do you think about a noise shroud on a generator? Is containing the generator's heat good?
I guess you could look into changing the injectors. But in doing so you may lose the ablity to run a higher RPMs/speeds. And perhaps changing thermostats so they will run at the proper temp. at low RPMs.
I don't see any advantage to containing the genset heat. Some might say it's a bad thing.
Now noise is of course a different issue. If you're going to use a shroud, I like the ones with a clear panel or two. While they may not deaden the sound as well as the fully insulated ones, it sure is nice to be able to look over the genset with out having to remove the panels duing an engine room check.
