I have 3 different diesel generators. Two of them are Lister CS diesel engines, the kind you crank-start by hand.
One of them is a modern Kubota single, water cooled engine with a belt drive 9.3KW generator head. All of the engines are healthy, and produce no visible smoke.
Because I find diesel exhaust particularly disagreeable now, (I was not always this way) I'd like to install an inexpensive Diesel Oxidation catalytic converter to reduce the characteristic exhaust smell on at least one of the engines and see if it helps. It's not a crusade to improve emissions for environmental reasons, but for my personal pleasure. Also for a bit of experimentation, as if it works, I'll equip all 3 engines with Cats.
I was reading about how Diesel Oxidation catalytic converters were used early on in mining operations to reduce the smell and make mining operations tolerable. So there is a long history of using them on low tech stationary engines. They will "light off" at 200 degrees C (just under 400F) and will stay functional at any load after that.
I found a MagnaFlow 2 inch 53004DM catalytic converter online for $90, but when I ordered it, they told me it was obsolete and could not suggest a similar alternative.
The flattened shape of a universal cat is ideal, as there is a bit of a clearance issue on one side. A round unit would not be a good choice.
Thoughts?
