Loud generator

I've got a 2016 View with a LP generator. Any ideas on how to quiet it down?

If it is an Onan 3.6Kw, it meets USDA Forestry Service standards.

Page 4.... of the following...


https://power.cummins.com/sites/defa.../F-1823-EN.pdf


Basically, 70 db or less at 3 M (~10')


I would look carefully at the installation on your coach to be sure that the unit is not rubbing on the frame of the RV and sending vibrations to the coach.



A second suggestion is to install a resonator on the exhaust pipe. Mine runs a straight exhaust (like almost all small Onans). The resonator will remove some of the higher tones in the exhaust. Resonator is an ONAN part.



Some folks have gone to a bit of expense and effort to box in the already boxed in unit to damp the vibrations and noise. However, you have to be very careful as the units are air cooled and draw in air from the side facing you and exhaust it out the bottom of the unit. You don't want to reduce the air flow.

Edit: Just remembered.. Putting a piece of astroturf type (grass side up) mat on the under the generator vs. hard flat surface will help absorb the sound vibrations.

Operate with the green cover in place and the RV's hatch closed.

Sorry, there's really no great solution here. Just be thankful you don't have a diesel unit that produce a low, bass drone. Low frequency vibes = more sound energy that transmits farther and may be more annoying. Think of the moron with the huge speakers and amps that pulls up beside you at a stop light. You can hear them from half a block away.

Right now I as m starting a project to reduce the exterior noise and interior noise of a onan microlite 4000 installed in a 2007 Fleetwood tioga 31 ft its mounted in the rear on the driver side below the bedroom closet, when I finish I hope to get dba readings before and after the mods, so keep checking back.

Visually everything looks good, I might try some kind of resonator and set if that helps. Carpet does help. Thanks!

First crawl UNDER and inspect closely/ well for loose/ damaged parts/ joints/ hangers. On mine, GEN is on rear left, and PO had APPARENTLY DRUG IT ON DRIVES before, knocked HOLE in muffler, LOOSENED the pipe joints, and also had the tip of exhaust pipe still UNDER the vehicle instead of protruding the recommended 1-1/2". My 99 Emerald Plus (BGE-series) has the muffler below the GEN. If I believe previous owner, he had NO IDEA? NEXT you need to identify what TYPE of Noise? Exhaust/ leak noise? Mechanical Scraping from rotating parts? Vibration? (E.g. Mud dauber or wasp nest can cause scraping/ lock an engine down even, or throw rotating parts out of balance) Is noise issue Inside the coach (vibration/ harmonics?) or outside decibels? Valve click? Piston Slap? (Checked the oil level?)

Everything is good on it, the RV only has about 16K on it. It's just a loud generator inside and out.

You might want to look at Dynamat products and see if you might be able to use this to reduce the noise. I used Dynaliner on the doghouse in my class A and it helped a great deal. I'm thinking I might do my generator box also.

Dont know why onan does not make a gas inverter generator, their small 8k quiet diesels are inverter and are super quiet, had 2 of them. Reliable beyond a doubt, sold one Monaco with 8,000 hrs

BUT is the loud from mechanical or EXHAUST? Have seen many V-8 or V-10 or straight-4 w/ NO BELT NOISE, NO BEARING NOISE, NO LIFTER/ ROCKER CHATTER, NO EXHAUST LEAKS= so quiet you had to see it spinning to know it was running?
