Generator exhaust

A length of flex pipe between the generator exhaust and the rigid stack pipe. Not sure how small flex you can get, so you might have to get an adapter and use lager diameter stack pipe. I would recommend curving the flex pipe down from the generator to ensure it doesn't bind as well as reducing the risk of rain getting down into the engine. Leave plenty of slack.

 

IDK, but just wanted to say, I think that's a great idea. I'm assuming you're talking about a gas powered generator? I've parked next to folks running one on occasion and the exhaust fume smell was horrible. I also worried about carbon monoxide levels. Even went out and bought a carbon monoxide alarm and have it mounted in my sleeper berth close to where I lay my head. IDK, with all these trucks running while parked, just seemed like a prudent idea, just in case. Hopefully, it never goes off because I never have a problem. But, I think it was well worth the miniscule investment of about $20 and a new 9 volt battery about once a year.

 

Yep, as mentioned, flex pipe. Maybe a large diameter piece of flexible galvanized electrical conduit. with a wide bend from one side of the generator or cover to fairing bracket, then up high with a small elbow, so it’s pointing down to keep water out. I had one, never put a pipe on it. Just my ideas. Even considered a larger muffler or adding another muffler. Never did it though. Like to see what you come up with. Definitely don’t like all the fumes floating around. Can’t be safe.

 

Well first Dino, don’t complicate things, you won’t be driving with it running so you can figure out how to mount one part of the pipe to the sleeper and use something very flexible (shop exhaust tube) that you can attach when you stop.

but let’s talk about safety for a moment, there was a recent tragedy at a music festival the past week where three people died because improper venting of a generator that wasn’t attached to a trailer, so I recommend people to think about proper venting and even thinking about using something like this

The older pete’s had cab mounted stacks with flex pipe down by the frame. Normally lasts several years before needing replaced. Look at the newer pete’s and KW’s and they have frame mounted exh with a slide pin at the top of the door. That’ll give you some trucks to look at for ideas.

 

Mines mounted on trailer. Never smell or even hear it unless it is running out of fuel. Quieter than the last APU I parked next to. It is also further away from other trucks unless then bobtail park right next to it. I do have a C02 alarm as well.

 

I used 3/4" EMT and bent it to follow the truck's exhaust so it wasn't attached to the cab. Then I cut and welded a flange that was the same shape as the spark arrestor plate, with Permatex copper as a gasket. I ended up making two pieces, like a midpipe and a tailpipe. I used to have it as high as the old exhaust, but there was nowhere to safely secure it. If you do not secure it in multiple points, it will vibrate loose and break.

I've also used flexible exhaust tubing. It's a lot more forgiving, and an easier install provided you have a nipple on the exhaust you can attach it to. But it rusts and leaks a lot quicker. It was particularly vulnerable where it attached to the generator.

I haven't had any problems with fumes or carbon monoxide with the exhaust running only about 5 feet up the cab along the exhaust bracket. If I wanted to go higher, I would probably attach a flexible tube at the end to finish it.
