Start-up smoke mitigation
Posted: Tue Aug 11, 2020 1:59 pm
Others have talked about this, but I'd like to collect the common wisdom on how to mitigate the smoke on start-up after a Pinz has not been started for awhile.
It's understood that the smoke is a function of the engine design that there are no oil seals on the exhaust valve stems. This thread isn't about how to change the engine, but how might we deal with the smoke cloud and oil mist that results.
I find the smoke is for maybe just a minute, so I'm brainstorming ideas here on how to minimize the smoke. One person mentioned using magnets to hold a rag over the tailpipe to capture the oil mist, but I suspect that doesn't address the smoke.
Some random [unvalidated] ideas, in the hopes of creating others from the field:
- A large bag, slightly permeable, to capture the exhaust. Dense canvas?
- A length of PVC pipe stuffed with fiberglass insulation?
- A box with multiple(?) furnace type filters?
- Electrostatic filter like used in bars as "smoke eaters"
Anyone tried something and had a success or failure to share?
