Call me crazy, but why doesn't someone make a kit for a fuel injector you could mount in a weld in bung in the exhaust pipe before the DPF to bypass the exhaust stroke injector sequence? If the factory programming triggers an extra injection of diesel into the cylinder for an auto regen on every exhaust stroke at 47% full. Why not use a Pi or other mini computer and an auxiliary fuel pump to manually inject just enough diesel into the exhaust just in front of the DPF to generate enough heat for a "regen" that occurs before the automatic regen. Say at 44% fill? You're injecting it into the exhaust before the start of the factory sequence trying to get ahead of the factory "auto regen" that seems to be damaging engines through fuel dilution of the oil.
Is something like the Banks engine monitoring stuff able to see the right data to monitor it? Can you track the needed data via CanBus? CanBus is being used by aftermarket pseudo Raspberry Pi's for 3D printers and some have the chips to do CanBus right on the board so it should be able read the information if available with the right programming. In theory you could make it a standalone module/system you power by say an auxiliary switch and a tap into the CanBus system. Maybe even spoof the readings if there are O2 sensors on either side of the DPF for the sequence also if they would throw codes. (it's a new truck to me I haven't crawled under it yet just paranoid from reading the stories)
It wouldn't prevent a DPF from filling with ash. And in an engine with another problem it would probably make DPF replacement more frequent/likely if you are triggering a regen slightly earlier. But it would sure seem to prevent the more expensive fuel washdown damage to the engine.
Am I crazy or do I need to try to make it?
Is it plausible? Would you buy it if it was available to have regens other than the 24 hour timer based one happen outside of the engine?
