Yessir, there are still cars on the roads and trails with carbs in them.
warm air - this has the potential to open a debate that I'm sure will be heated! (TracyG isn't the only one around here who can be funny...)
Moving Forward, if you've found an interesting patent, why not post a link to the webpage so we can all go to it? It'll take some load off the Groove's webserver...
warm vs cool intake air, preheat vs cool fuel prior to the induction stroke, fuel supplementation with HHO or water vapour, EFIEs and MAP modification, timing, fuel reformation with additives...these are all topics I'd love to see what everyone's opinions and implementations are.
maybe I'll follow Kenneth's lead with my own proposed discussion:
I added a BMW cyclone seperator with catch can to my PCV mod. After a VERY short time (maybe 600 miles), the catch can was full (it started leaking out the top seal) of goopy water that smelled of fuel. I emptied it and drove on. another 600 miles later, it was full again, but this time with water that smelled of fuel - no oily goop. If my blowby is mostly water vapour, I'm guessing that the engine is running rather close to peak efficiency. rather than collecting and dumping that water, wouldn't it be better to recycle that back into the intake airstream with a water injection system, especially since there are some fuel distillates in it (from the smell)? WW2 bomber engines used water injection to make scarce aviation fuel stretch farther, as well as to enhance engine performance, so wouldn't the same hold true in a car engine of advanced design, as in today's cars?
