Hi everyone, I thought I had put a question on the forum, but I cannot see where it has gone!!. Never mind I'll do it again, sorry if you see it twice!!
I have a 1997 Plus 8 4.6ltr
I have been looking with interest at the big black plastic container in the engine compartment situated on the passenger side rear in the engine compartment.
This has something to do with fuel vapour capture from the fuel tank and I believe helps with fuel emissions and reduces fuel smells from the excess vapour.
This device is connected to the vacuum side of the air box and connects to the vent on the fuel tank.
There is an electrically controlled valve that I imagine opens at some time to allow the excess fuel vapour into the airbox.
Does anyone know much about this device?
What triggeres the valve to open, is it something to do with the ECU?
I cannot see much info on the internet about this!
Thanks all.
Martin
The valve is triggered at cold start or when at full throttle when a rich mixture is needed
