is the multijet avilable in the UK now in stilo guise?

just i had a "stilo sport" brochure in the post today, stilo schumacher, abarth etc. and it mentioned the 130psi multijet sporting or something similar - i binned the brochure but can prob dig it out.

Yes it is available to order

any idea on price? couldn't find anything on fiat.co.uk

The multijet is now on the fiat website. Price wise its £12,600 in Active trim, or £13,631 in sporting trim.

Tis about time!!!!!!

120bhp ? looks like its still the 8v jobby then
not much of an increase from 114bhp that was being used up until now.

Curious thing is, they call it multijet but in the specs it sats Fuel feed = Unijet, guess its just a web mastering slipup

int the multijet 140 bhp

I checked this on the alfa website a few minutes ago, it refers to the JTDm in both 120bhp and 150bhp 16v, so I guess multijet is the same as MPI on a petrol engine.
Fiat website definetly says 120bhp as well, 4cyl, 2valve (same as the alfa 120)engine meaning the 8v

wel i though they did a 115 bh and a 140 bhp just after looking at other peoplse threads i could be wrong

just had a look it is 140 bhp and its a 16v engine no 8

No, it's not the same as MPI.
MPI on petrol engines is Multi Point Injection, meaning that each cylinder has it's own injector (where an Single Point Injection engine has one injector for all cylinders).
Multijet means that the commonrail system is capable of up to 5 seperate injections during each engine cycle, while the old JTD system was only capaple of 2 seperate injections during each engine cycle.

The following is taken from www.italiaspeed.com:

140 bhp 1.9 Multijet

In 2002, the Fiat Group introduced the second generation of Common Rail power units, 16 valve JTD engines with Multijet technology. The first of this new engine family in the world was the 140 bhp 1.9 Multijet, now making an appearance on the Fiat Stilo M.Y. 04 (saloon and Multi Wagon) paired with a 6 speed manual gearbox of sporty configuration.

This offers various advantages. The engine is quieter as it warms up. The improvement can be quantified as a reduction of 3 to 6 decibels depending on engine speed and environmental temperature. It is also very powerful (103 kW at 4000 rpm) and torque is generous (31 kgm at 2000 rpm). Despite these searing performance figures, the fuel consumption is low. The new power unit also reduces emissions even though it is not fitted with sophisticated exhaust gas treatment devices.

Now we will take a detailed look at the architecture of the new engine and, above all, the results achieved with the Multijet system and sixteen valves.

Power unit architecture

This engine is derived from the tried and tested 1.9 JTD 8 valve Common Rail unit and takes the form of a 4 cylinder in line unit with bore of 82 millimetres and stroke of 90.4 millimetres. The four valves per cylinder are driven directly by a twin overhead camshaft. The new turbodiesel has undergone several engineering changes to increase performance and engine torque at low speeds and to reduce noise levels and vibration.

For example, the Common Rail system used on the 1.9 Multijet 16v unit includes two new strategies for automatically calibrating and balancing the diesel injected to lower noise and reduce vibration.

Certain engine components are brand new: a cylinder head with hydraulic tappets, steel connecting rods and crankshaft, a piston with an internal channel to carry cooling oil to the main and connecting rod bearings that are made out of different material to the previous unit. The exhaust and intake manifolds are also new: the former is made out of a special high-strength material while the latter is made out of pressure cast aluminium.

The electronically-controlled EGR system is cooled by exhaust gas. The lubrication circuit has a new oil pump and an external heat exchanger (air/oil) for cooling the oil. The cooling system is fitted with a different water pump. This long series of improvements and changes have created a reliable, powerful engine with low fuel consumption.

The Multijet system

The adoption of the Multijet system makes the 1.9 JTD the first second generation Common Rail engine in the world. The underlying principles remain the same, i.e. high injection pressure and electronic injector control. But one extra feature has been added. During each engine cycle, the number of injections increases over and above the current number of two. In this way, the same amount of diesel is burnt inside the cylinder but in several portions to achieve smoother combustion.

The advantages include lower running noise, reduced emissions and a 6-7% increase in performance. All this comes with a level of engine efficiency that improves car handling still further.

These results are not to be underestimated, particularly because they are obtained with an engine that represents an incredible leap forward from prechamber diesels and even improves on first generation JTD engines.

The secret of the Multijet engine lies in the control unit that governs the electric injector opening and closure system (and also in the injectors themselves). The crucial part of the engine is the electronic control unit itself, due to its ability to deliver a series of very closely-spaced injections.

Fiat Auto's researchers developed the part (together with the injectors) especially for this application. It is designed to deliver the multiple injections that assure the designer more accurate control of pressures and temperatures developed inside the combustion chamber and also more efficient use of air taken into the cylinders.

This enables further goals to be achieved: quieter combustion, reduced emissions and increased performance. The Multijet system is underpinned by long years of research. Our engineers began by resolving the problem of limits imposed by the control units. Then they went on to map the benefits they could achieve by plotting different multiple injection sequences (two secondary injections very close to the main injection; one secondary injection not too close to the main injection plus two closely-spaced secondary injections; one secondary injection and then two main injections close together after a certain period etc.) against different engine service conditions: in the idling region; with low loads and low rpm; with high rpm and moderate load; with low rpm and high load etc.

The study revealed the potential of the system and showed that great benefits are achievable in all cases, though these tend to focus on one field or another according to the type of sequence chosen and the engine service area targeted. In some cases, for example, the priority is to reduce start-up times and fume levels, in other cases it is to increase torque and reduce noise while in others it is to reduce emissions and ensure a quieter drive.

how long lol!!!!!!!!! my brain herts

they now do the multijet BUT its 120bhp instead of 140 and only 5speed box not the 6 speed euro version

imo whats the point in increasing it by only 5bhp from the standard jtd that i only baught 6mnths ago new :bang:

Only 5bhp, but is there more torque? Better efficiency? Less emissions? Less noise?

I think so

i cant believe about the 5 bhp i thought they still did the 140 bhp still saw 1 in my dealership the other day thats all

No doubt the 120bhp can be nicely remapped....

They still make the Stilo with the 16v 140/150bhp multijet engine. It's only Fiat UK that doesn't want to import it,justlike in denmark.
I was lucky to get my 140bhp multijet last year, as they don't sell it in Denmark any more you can only buy the 120bhp multijet like in the uk.

can anyone confirm this, are all the components on the 140bhp multijet the same as the standard jtd? ie. exhaust manifold, turbo etc?

I think that one of the only things the 140 bhp multijet and the standad jtd (i assume you mean the 115bhp version?) has in common is the engine block.
You have to remember that the 16v multijet engine is a completly redesigned engine, when compared with the 115bhp jtd.

They may have reused some of the components, but i really don't know (which when i think about it is'n helping you very much...... ).

i know the engines themselves are different but was thinking more the things attached like clutch etc.
