MEP-802a catalytic converted or dpf

[rcamacho]

I’m looking to cut the diesel fumes a bit on the property. Anyone adapted small cat or dpf to the npt exhaust output?

I wouldn't think that adding a Cat/DOC/DPF to a 80x set would be a good idea. These sets were design for the military and they are generally exempt from most emission/pollution controls for the sake of reliability. A cat/doc/dpf needs a certain temperature range to work effectively.Too cold and the catalyst won't activate,too hot and they melt. Plus the additional cost of the components needed for the system to work properly would be very expensive for a retrofit. and not to mention the packaging requirements for those components.

I did a quick lookup on a Tier 4 emission 4 cylinder diesel engine. Just the DPF for one ranges from $1300 to +$2400 new. And i don't think that includes the DOC, which can range from $500 to $1200. Then add the cost of the necessary ECU controls to make sure the system runs properly...and its honesty not worth it in the end.

Propane injection?

A tiny turbo?

Those in my opinion would be better than doing a DPF.

Its not designed to have it, its only going to hurt performance. Perhaps you can change the location of the machine and its exhaust exit height, to help?

Forget it. Buy a civilian genset if you don't like the MEP.

Love the MEP, just tired of hearing my spouse gripe about it.
I’ll move it farther out and route the exhaust

If your spouse can't stand the noise... find a friend with a big box style gas genset and run it next to your MEP when they are within listening distance.

even better, get an MEP 002 and run it beside the MEP 802.

As for the original question- there is way too much engineering that would need to be done to get a DPF installed. It would need EGR and additional controls to elevate the exhaust gas temps sky-high to perform regeneration.

If you were going to attempt to go through all that trouble I'd think you'd be better off making closed-system water scrubber for your exhaust... essentially a diesel water bong. No more soot and much less noise... but what you'd do with the sooty water I have no idea.

My wife hates my MEP003A as well. The MEP003A is much noisier than your MEP802A., but has proven to be very dependable. My wife says it stinks and is too noisy. She hates it with a passion until the power goes out in either the hot summer or in the winter cold. Then she loves it. However, her memory is short and within days of the power coming back on, she hates it again.

MEP is running today, she’s not complaining...

After the first real outage the wife totally changed her opinion about the old military iron out in the yard.

I've heard of plenty of people wanting to let an engine run but not many who want to plug up an efficient running deisel with a cork. I thought this was a joke at first.

john Deere does a genset with a four cylinder turbo no def dep or cat 50 state legal, quiet Broad Crown Gensets 30 KW

I'll say that a turbo or propane injection both can greatly reduce soot. A turbo is more complicated to install than propane but it creates another fuel stream. On the plus side you don't have to add that much propane to tidy the exhaust up and unlike DEF you don't damage anything if it runs out.

I’ll be moving the genset about 30’ from the house which should mitigate the noise level and dissipate exhaust a tad more.

That's by far the simplest solution.
