Hi.
I own a Fiat type 1.4ie the year 93. Spends a lot of gasoline, 10-11 l / 100 km.

It can be in the fresh air? Before the air filter there is a thermostat which opens and closes a butterfly. When the engine is cold the valve is closed, and when it reaches operating temperature the valve opens fresh air to mix with hot engine air. In my car does not happen, the valve is always closed hot air getting into the engine all the time. It can be fixed? Porter manual says you have to change the whole box, but can not find the parts. What between warm air to the engine is not bad for its reliability?
Would not it be better to block the valve in open position always? I know it would be worse for cold start. Fortunately this winter has chilled a few days (have not dropped -4ºC almost never).
Thank you very much for the answers.
I'll come asking for advice, the car has 90000km, almost every city. And that wears a lot.
 
Think it switches only when the weather is warm (very), so give it 8 more weeks at least, depending where you are located. Need to remember 15 years ago:eek: Don't think they break, if in really warm weather which was never in UK it still doesn't alter then maybe take a look but warm air is no problem cold air is bad for fuel and engine wear. Its coming back to me now, I tried to force it thinking it should move till I had a car that you had to manually change the pipe over only when the temperature reached a desert temp, so leave it, working fine.

Hi, and welcome, :)
the valve it supposed to help in Cold start running, .. as you say it is not so good - feeding HOT air into a HOT engine..:eek:

:idea:you can drill out the rivets that hold the valve..
SFB may help with some of the details:)

I had this out with Fiat years ago, its working, 99% of the time u need warm air.

Hola Alberto, bienvenido al foro.
I've had a problem with this valve, but it apparently locked itself open, not closed, so I relied on the choke (estrangulador) for cold start and didn't investigate the problem.
Later on, the valve fixed itself and now seems to operate as it should.
Leave it with me for a day or two and I'll get back to you.
Saludos,
Pepe
 
It didn't fix itself just wasn't broke but was a warm day in southern spain, its not open or closed always open just which side. Has it got that crazy fuel consumption gauge that nearly cost me my life a few times?:slayer:

It didn't work for a whole year, including the few cold (0º C) days we get here.

If you mean the vacuum gauge, yes, I find it quite amusing.
Left the vac pipe off it once, nothing serious happened.

I see you speak good Spanish, LOL.
Just looked back and noted "the car has 90000km, almost every city."
I'm glad I live in the campo, no traffic, ever.:D

Thank you all for the answers. The car was of my sister, and they used it in town all these years. They had no maintenance beyond oil change and air filter:eek:, (I changed the timing belt and the alternator belt, the same as the dealer and the thermostat). The unfortunate car is now in my hands. I live in the countryside, so I don't drive in town so much. I have noted that consumption by road riding. At an average speed of 100/120 km/h, The needle the revolutions rise to 4000rpm at 120km/h , consumer and needle standing on the edge of the red zone.
360km with 37 lots.

pd : Previously I had a Rover 416si and at 120 km/h does not spend more than 7-7.5l / 100

I've only just fitted a rev counter, so I don't know what it should read at 120 km/h.
I think that around 3,500 rpm should be acceptable, but I'll be advised by anyone who owns a Tipo with a rev counter.

There are other reasons for high fuel consumption.
Brakes not releasing/binding.
Tyre pressures too low.
Spark plug condition and carburettor settings.
Any one or more of these could be la mosca en tu sopa.

Is the engine running well?
Have you checked the many vacuum pipes for leaks?
Suerte.

Late edit: The catalytic converter also increases fuel consumption a little, my 91 model doesn't have one.

Hi fellow Tipo owner. :)

I've done over 80mph in my 1.4... Just to test the engine, you understand! ;) I didn't keep track of the exact revs at the time, but I know it was nowhere near the red line.

Hope you get yours sorted.

Thanks for the info, Camo, but Alberto was talking about the vacuum gauge needle on the red, not the rev counter.
 
I don't think the hot air valve can be the cause of the fuel consumption,... and I don't know if when in the "hot" position it blocks the cold air completely. But you can remove the flexible aluminium pipe that connects the hot air valve to the exhaust area (if you still have it..), this should reduce the temperature.

You could try to spraty the valve mechanism with WD40 or something in case it is sticking with age.

If you changed the thermostat then this will prevent high fuel consumption due to cold running. But you should also change the temperature sensor at the rear of the inlet manifold, this gives and input for the ECU fuelling.

Clean out the oil breather hose and engine block connector that leads from the crankcase to the air filter box, this becomes full of old oil and grease.

The Tipo should give quite good economy, consider changing the spark plug leads and checking the compressions and valve clearances.

Can you tell me what year the car is? Does it have the earlier engine management system with a traditional distributor, or the later type with a coil pack on the roght side of the engine?

I hope you have success and the car enjoys its retirement in the country!

Hi, the car is a 1.4ie. Code motor 160AD. I change Timin belt, thermostat, the sparks. The rev marks 3000 and the car goes to 94kmh +/-.
It cost reach 4000 in 5th .
And in ALL of the rev/gear the gauge of the econometro stand in the 3/4
And, of course, when i make a Stop after the "walk" the revs down at 500! :eek:(i know its a typical matter)

The temperature sensor? The car passed de MOT very well the last year.
