Title: LPG Fulvia
Post by: simonandjuliet on 20 March, 2017, 08:26:58 PM
I spotted this photo and was intrigued by the extra pipes and then saw why . Not come across an LPG modified Fulvia before - wonder how well it works ?

Whats the contraption in front of the Cam cover normally occupied by an oil cooler if fitted?

It's the heater fan air intake........ it's Fulvia Sedan!

You should see the Diameter of the flexible trunking, then marvel that something this size delivers so very little air inside the car. ::)
Can't say I've ever seen a Fulvia with a coil cover before, I'd have thought from personal experience that it is totally unneccesary.

I suspect the size of the trunking may be the problem. The larger the trunking the bigger the volume of air you have to shift to get a decent air velocity at the vent. More modern systems have a big fan in an air box but relatively small trunking.

Thanks Frank, I'll look into what I might be able to do about it with that in mind.

If your set up is like this picture I suspect the big trunking is before the fan so wouldn't be the problem. Getting a more powerful fan in the system would be the trick but space would then be an issue. I am not short on Y10 fans and air boxes if you could make something out of that but any modern fan I can think of is centrifugal which would be difficult to make work. An alternative approach would be a more powerful motor in the existing position with a more modern design of fan blades.

My experience with Fulvia Sedan heaters has been that the real problem is getting a good flow of hot water through the heater when you want it. And somewhat frustratingly in the past I have spent many abortive hours trying to improve this without success. Our current Fulvia GTE has an excellent heater and since we acquired it a couple of years ago after it had been standing for some years I have done nothing to the heater! It just works very well.

Thanks Frank & Chris.
I've completely rebuilt my heater twice with very careful attention to sealing the case, the first time was when I put Fay back on the road in 1999, and again in 2006 after coming back from Turin, the end plate on the heater radiator split and leaked coolant into the airbox, it was so well sealed that the coolant only came out as I went around corners, with Diane holding a container under the right or left heater flap as necessary, but it was very difficult to locate the leak, as the split only opened up under pressure once it was removed, my thoughts were, did coming back over the Alps have an effect.
I've been looking at the fans I have in my Airchamber that are similar to computer fans, and I'm looking at trying one of these in place of the original fan, if nothing else it spins faster!

Another thought Brian, would be to try putting the air chamber fan on the original motor. I am thinking that modern fans have a much more sophisticated blade design but am not sure how powerful the air chamber fans are for shifting large volumes of air. Presumably in the air chamber they are just topping the air up. Your results will be interesting.

Worth looking into.
although the Airchamber fans (2) in normal use only top up the air, they still have to fill it up initially, which they do very quickly. there is also a constant bleed to change the air, so they are quite powerful.
