www.alfaromeo.i... Massimo Fulfaro, one of FPT's Development Engineers, will be showing you all the technical details of MultiAir, using an example engine.
Hello my Friend. We are not interested in how it works inside there, but given that this engine has a serious design flaw, namely, it does not start after a long stop (more than 2 weeks) despite the operable kinematics of the control of valves by the Multiair module due to oil leakage from the module and the formation of air pockets in it. This disadvantage is exacerbated by the traditionally high oil consumption in this engine and the user can actually miss the critical moment of adding oil to the engine. In my case, this happened, the oil level dropped, when braking or tilting the car through the suction pipe, air got into the oil system (Multiair module hydraulics sistem) from the crankcase and the engine stopped. After topping up the oil, attempts to start the engine were unsuccessful. At the same time, compression and spark in all cylinders disappeared in the engine. The last oil 5W40 change was - 8000 km. back. The filt Multiair module er turned out to be clean, the mileage of the car is 960,000 km., the condition of the engine is good. Questions: 1. How can I bleed the Multiair module and remove air from it? 2. What is the luMultiair module brication scheme. 3. Why is there a small ball valve on the , from Multiair module he top under the filler neck? what is its function? Some experts in Utah advise pouring 240-280 ml through it into the Multiair module oil and then try to start the engine againe. I tried topping up, but nothing came of it, because the hole (1 mm) is very small. Senserly yours. Igor Groza 18.01.22 igorgroza1957@gmail.com
In a hybrid setup where an engine only charges a battery or hydraulic accumulator, an engine is best to run at a constant speed at its efficient "sweet spot". That does not require this variable vale timing complexity. The engine can be much simpler, or even a Stirling which is even better.
Yes, but you exchange one set of problems for another. Adding a battery increases weight, cost, complexity, need for lithium mining, less serviceable, etc. Only Toyota managed to make a reliable hybrid, the rest are struggling still
you‘re one of those morons who don‘t service their cars right? or use different oils than what fiat recommends? and then you go cry around when something fails. classy.
@@South4153 that's not nice. I used everything that was needed. Even the special brand of oil. Yes there are different brands with the same specs, but I used the special fiat advised. Because I know about the oil being really important. But you call me morron. Sad. The previous owners might have used the wrong oil. Even so the valve system should just unscrew. That's what happened. It's badly made. Also fiat have changed the design somewhat the newer versions don't fall apart like that. Yes my model had the earlier crappy multi air unit. So no about the morron mister namecaller troll. Also do research, the oil doesn't cause the valve plungers to unscrew, that was a design flaw.
The servo controlled valves on just one side appear to be a hybridization of an engine that I see being developed by Koenigsegg. If one could accurately predict angular position and velocity with a sensor all that cam follower stuff could be done away.
This is so true, however I believe that Fiat won't be selling this technology.. Back in the day they needed the money when they sold their technology but that isn't the case today and I hope they realize that they certainly would make a bigger profit to keep this and future technology in their own cars!
Yes man that would be nice to keep their projects to their own cars, MiTO is such a great car, MULTI-LIFT engines RULES, we will see if they sell stuff for money, but you are probably right, they are big ow and have big revenue!!! FORZA ITALIA, FORZA ALFISTI!!!
I always was a happy driver in my TwinSpark Alfa’s Also a bit problems but now im owner for 2 weeks for the MiTo. 155hp 6-Speed. Still happy. Its a 2009 model with 130.000. Now 2021. We will see 😎🍀
10 % more power and 30% less fuell consumption in confront of the traditional 4 stroke who had 0,9 times the power of this new engine. yeah it's worth all this . This is the good side of Italy
@Sanyey comparing Opel and Fiat / Alfa, with my experience, Opel is much more resistant but not more faster! My uncle has a blue Opel Kadett by Bertone! That is indeed a car for life! Never let him down. My brother had a Alfa Romeo 147...he had so many electric problems... My girlfriend had a Mito...in one year, she had to go three times already to a car workshop...
X caso ho trovato questo video! Sono disperato la mia MiTo usata a quanto pare lo ha cambiato ma nn mi dà pace da fredda si accendeva 3 cilindri poi dopo un po’ che cammino si accende la spia motore con messaggio Start&Stop non disponibile far controllare il motore, va in recovery poi dopo un po’ rifunziona, L’ errore è il P1062 all’ improvviso dopo una sosta riaccendo e sparisce la spia! Cosa si può fare senza doverlo sostituire di nuovo e soprattutto se è un prob di fabbrica a quanto ho letto da qualche parte perché la FIAT non ha fatto i richiami per sostituirlo in garanzia, spero che leggerai questo commento non ne posso più veramente!
all petrol engines are obsolete, we had hydrogen engines since 1857 Eugenio Versanti and if you'r smart you can immagine that a multi air engine works even better in a hybrid combination since it is way smaller bult
Incredible technology compared to variable valve timing, however, instead of using a timing belt, why couldn't they use a chain, save the hassle and cost for many owners across the world.
it just goes to show that.... the biggest engine isn't always the best 1.4l producing 135 - 170bhp some 2.0L engines can't produce that Fiat are the daddy!
"Fiat Powertrain Technologies" is made up of engineers from Maserati, Alfa Romeo and Lancia :) hope this helps... also the problem of running 170hp from a 1.4 is greater strain on various running gear (meaning shorter maintenance and part replacement intervals). This is proven by the factory service schedule - timing belt needs to be changed every 65,000km and various additional checks (normally 100,000-120,000kkm for similar sized engines). Oil change frequency is also much shorter (every 3months at most).
e' stata una bella idea, della tanto criticata fiat. e pensare che già 10 anni fa la mercedes aveva chiesto alla nostra marelli di inventare qualcosa di simile senza pero' trovare una soluzione adatta. brava la Fiat
thanks to the victorians we are stucked with mineral fossils, so let us italians make the best of it for now, we had hydrogene engines 20 year before some german invented the 4 stroke engine so even the complexity electricity hybrid would be not required and ships could run on a sea of fuel
Dont be such a swagger man. Racing inspired videos? dont make me laugh. Fiat / Alfa cars are genial, beautiful, but saying this is another territory...do you have a Bugatti, a Ferrari? thats indeed another territory, but an Alfa Romeo? Maybe you just have 18years old and you are excited...its comprehensive! Wake up! And respect!
"30% less fuel consumption"? Look again. This is all nice but all too late as hybrid-electric or hybrid-hydraulic is far superior, using a charging Stirling engine.
then OK, i just wanted you not to saying Alfa is shit, i don't tell anybody that his car is shit, BUT I DON'T LIKE WHEN SOMEBODY DOES THAT TO ME, so i thing we are COOL NOW, by the way, your GSI looks nice, i mean you are taking good care of your car, looks like new... BYE MAN!!!! i know you like OPEL, but don't come here just to spill shit, OK??? BYE!!!
if you like your opel go and comment on OPEL videos, and get out of racing inspired car videos!!! I DON'T COMMENT ON CARS THAT I DON'T LIKE, SO DO THE SAME, DON'T come on our territory, stick to your own territory!!!
To fix the problem with selespeed you need to apply silicone tuneup paste on the electrical connectors to prevent corrosion. The transmission itself is good. That's it. In fact this simple trick will fix most electrical problems in all cars.
Multiair is a hydraulically-actuated variable valve timing (VVT) engine technology enabling "cylinder by cylinder, stroke by stroke" control of intake air directly via a gasoline engine's inlet valves. en.wikipedia.org/wiki/MultiAir
Made for girls???? On what planet do you live on pal??? GSi-s were made for young MAN, to kick GTI owners in the ass with it... On the other hand:Puntos, Lancia Y-s, Tipos, Unos, Fiat 500, Alfa mi-to-s are made for girls indeed!
OPEL KADETT GSI CABRIO BY BERTONE (my current car) IS THE ONLY "PART ITALIAN" CAR I BUY... Originally Italian made (Fiat, Alfa, Lancia)= S.H.I.T. piece of unreliable Shit! Opel 4 life :)
Fiat Punto Evo Sport 1.4L Turbo 200cv. De la merde ce boitier MultiAir !!! 130000 Km et il déconne déjà ! Voyant moteur, mode dégradé. Problème de fabrication connu par Fiat, mais rien est fait !!!
