New Engine Technology for Fiat
Posted by admin on Feb 19, 2010 in new technology |
Fiat Group and Fiat Powertrain Technolgy unveiled its new air management technology ‘Multiair’ at the Geneva Motor Show. Multiair is an electro-hydraulic system of engine valves for dynamic and direct control of air and combustion, cylinder by cylinder and stroke by stroke. Thanks to a direct control of the air through the intake engine valves without using the throttle, Multiair helps reducing fuel consumption; and pollutant emissions are likewise reduced through combustion control. Video animation explains how the new technology works.

@qiranwang : the …
@qiranwang : the hydraulic pump is only a system to open the valves, it does not help in any way to the flow of air through the intake process. The idea is that when you are slowing down, your engine does not need full compression power stroke, as well as during shifting…so it only opens the intake valve half the time…and during a rev-up, the time the valve is open is increased. This system can even be turbocharge (if it isn’t already) to better the system.
o thanks for …
o thanks for clearing me up, so it’s like a hybrid air intake system that uses both the conventional vacuum of the cylinder and the new hydraulic pump?
@qiranwang : no, …
@qiranwang : no, it’s the intake overhead cam replacement. What it does is when the cam use to tell it to open the valve, it tells a hydraulic system instead. The electronics tell the hydraulic to allow or disallow the valve opening, it’s a redundant system (both the cam AND the electronics have to say “open” for it to open). This allows a neural net software system to control the valves to produce best situations to create best fuel mileage.

I have seald my Fiat , and buyed a Car !!!!
so basically, they …
so basically, they are using another pump to suck air into the engine? what about the vaccum that’s suppose to suck air? it has no effects anymore?
Avoid vaccines, …
Avoid vaccines, they contain aluminum, mercury, aspartame/formaldehyde, squalene, mutagens etc that cause diseases like lupus, arthritus, Gulf War Syndrome, Sheeple syndrome, Parkinsons, Alzheimers, allergies, asthma, cancer, ADD/autism etc. Still the WHO is pushing the genocidal h1n1 shot when they should promote vitamin D3, garlic, silver products etc to oust za vampires & verevolves!

You would think so …
You would think so as it was Fiat that first patented the design of variable valve timing VVT in 1960’s (later copied and modified again by Honda and called VTEC) and VVT was first used on a car in production by Alfa Romeo in 1980. So this new FIAT system is different in that whilst you vary these in VTEC it is set at rpm parameters not other info like adaptive conditions and temperature, eng load etc. And FairladyS130 what questionable durability or reliability? It ain’t a Datsun / Nissan!

A lot more …
A lot more complicated system than present with questionable durability and reliability?
More power with …
More power with more fuel efficiency, less polution. What could ever go wrong?
ok realmente é …
ok realmente é muito bom este sistema pois reduz os consumos e aumenta o binário e os Cv, mas vejam uma coisa isto não é o que a BMW tem vindo a fazer com o “Valvetronic” de há uns anos para cá a única diferença é que a BMW é que eles utilizam um sistema electromecânico e a FIAT utiliza um sistema electrohidráulico mas o principio é o mm =D
I don’t really get …
I don’t really get this. How is this any different from the already mechanohidraulic valve system already used in SuperFIRE engines, like the 80cv 1.2 used on MK2 Puntos?
Theoretically, yes. …
Theoretically, yes. None of the other systems are capable of delaying valve timing that much dynamically, or, as shown in the video, double-pumping in a single action. But that’s all in theory. In reality it will depend highly on solenoid valve speeds and hydraulic fluid flow, ECU computing speeds, data density, and a whole crap load of other variables that makes this so freakin’ complicated. Clear a few more technical hurdles and I don’t see why they would even need a cam shaft anymore.

would computer controlled electric-hydraulic system be better than vtec, valvetronic, or porsches’ vvt?

I hope with this new technology Fiat can do something about the problems their cars have in extreme cold and heavy snow.
