Re: [MBZ] Cleaning Injectors
Those are tempering temperatures only. Actual hardening requires cherry-red for steel. I'm sure most of you know this better than I do. And someone else mentioned self-cleaning oven, but couldn't that damage the temper of some alloys?

Re: [MBZ] Cleaning Injectors
Hard question, since the component parts are multiple different materials and to truly restore to the FAA requirement of "As good or better than new manufacturer standards" required dismantle to component level, then each component held at temp without damage to the base material. So, it's not a function of simply pitching an assembled nozzle into the barbque and waiting... General terms are 450F to 475F for time adjusted for component size, with ramp up and cool down so metallurgy of base part is not affected by cleaning process all documented to FAA satisfaction, of course.

Re: [MBZ] Cleaning Injectors
Both the short and long answer to that question is "NO". For a nozzle to convert a liquid to atomized droplets requires very close tolerances between a number of components inside the nozzle. Carbon is a strong material that doesn't "dissolve easily" and when baked on in the heat and pressure of combustion is "pretty damn durable" Example, the space shuttle wings were coated with carbon tiles to resist reentry heat. Same stuff on your nozzles. I have never tried Hoppes bore cleaner for cleaning nozzles, but I have tried a lot of other products, Of the ones that did work, they only "worked a little bit", and certainly not enough to restore good function. Thus, the success of adding Hoppes to your tank is suspect. The procedure I invented and got approved by FAA involved dismantling the nozzle to component level and baking those carbon covered parts in a controlled industrial oven for specific time and temp, which completed the carbon burn process and converted the carbon to a light gray ash, which was then removed by hand scrub of the components labor intensive, yes... but expensive jet engine parts were worth the labor cost.

Re: [MBZ] Cleaning Injectors
Just happens, I have more than passing experience with fuel nozzles used in Jet A environment and Diesel engines. [Jet A and No 2 diesel are nearly identical except Jet A has additives to retard gel point [it's cold at altitude] ] Bottom line, in BOTH uses, the nozzles become coated with coke and carbon in use, The accumulation of carbon degrades spray pattern and droplet formation. The size of fuel droplets is critical in flame path formation and fuel efficiency, ie large droplets don't ignite well, thus less heat energy, more carbon formation. So, it's not just a vergasser issue.
