Whats this...

[mas]

what is this in my engine bay, seems odd to have a pipe taking hot air from the manifold and putting it in to the feed for cold air?? :S



thanks alot,

Sam

its a pipe...

This is for starts in cold conditions...a flap will shut it off when the engine gets to a certain temperature.

ahhh,m was going to pull it off and get cold air in thee for once haha

As far as I can remember a lot of cars have them and the pipe uses the warmish air from the engine just after a cold start to help the fueling / choke.
There is a valve in there somewhere which stops the warm air coming through once the engine is up to temperature.

I think its mainly helpful for cold starts in the winter. Stops the car spluttering.

I may well be wrong though. I also had one on my old 8 valve Polo GT

Sounds spot on to me

I had this on quite a few of my old cars and there was always a valve which shut it off when the engine was up to temperature.

i took my airbox apart about 3 weeks ago
it sounds like it should, but it doesn't look like there is any automated control to shut off the warm air, it is just a flap on a spring.
so i guess when the engine's drawing a lot of air in, the flap opens a bit and cold air gets in, but not much! seems a bit odd to me, but it's only a 1.4 so it probs makes no difference.

Its just there to vapourise the fuel better when its starting under cold conditions as has been said above.
Most carbed cars have them, though I thought all the 1.4 energy lumps were fuel injected ?

they are, thats why i thought it was wierd. problably just there to warm engine up quick, for less engine wair or somethin, the E type 1.4 is no racing engine so they'd probably do that

My old Escort had a similar system and that was fuel injected....single point though so may be different on multi-point injection systems.

I'd still leave it in place though
