Default 1998 Accord FIAC Valve

I've been trying to diagnose a raw fuel smell in the engine
compartment of my 1998 V6 Accord. While removing the intake air
plenum, I was planning to replace all the vacuum hoses, including
those that go to the FIAC valve. Unfortunately, one of the valve
stems crumbled, so I have a new unit on order. But...

I'm hoping someone can explain to me the exact workings of this
valve. I see it takes fresh air in and places it into both sides of
the engine. But the top hose that goes to the TB...Is that a thermal
valve? Basically I'm looking for a good explanation of this part, and
I have not been able to locate one on-line thus far. I'm really
curious what the hose from the TB does exactly.

Thanks in advance,

Default 1998 Accord FIAC Valve

The fiac valve is the most random honda design ive ever come across as a technician. Fiac is an acronym for Fuel Injection Air Control. Basically its function is to spray air into the fuel as it is sprayed from the injectors.This aerates the fuel thus causing fuel atomization and smoothercombustion

"Random"? Can you tell me how you meant to use that word?
