If it significantly eliminates the need for cold enrichment, will there be an injector into the exhaust to light off the cat? I know that sounds dumb, but OEM mapping dumps a ton of fuel, above what the engine needs to run, to get the cat lit on cold start now.
It will be interesting to see if these are used in non-flexfuel gasoline engines from OEM's. Maybe they only mention ethanol fuel because it's just not hot enough to make a difference for a gasoline engine. Or not hot enough when the engine is warm. Or the heating element isn't capable of continuous duty.
Maybe that's what we are here for.
The claim for the supercritical temp injector (Transonic) sounds like it has promise though.
