Encyclopedia of engines: Fiat 1.6 Multijet (diesel)

The stronger variants of the 1.9 JTD unit were succeeded by its larger 2,0 liter cousin, but the smaller 1.6 Multijet replaced the weaker ones. Of the three, it turned out to be the most successful, the least problematic and just as durable.

This motor debuted in 2007 in the Fiat Bravo II as natural market successor to the 8-valve 1.9 JTD variant. In the small car, he developed 105 and 120 hp, and the 150-horsepower version of the iconic 1.9 was replaced by a 2-liter engine. This engine is not much different from Common Rail diesels, and you can even say that has a relatively simple structure.

There are 16 valves in its head, and the timing drives a traditional belt, which is recommended to be changed every 140 thousand. km. Nozzles until 2012 of release are electromagnetic. Interestingly, the weaker 105-horsepower version initially did not even have a particulate filter, and the turbocharger has a fixed geometry. The variable appeared only in the 120 hp version. In 2009, a weakened 90-horsepower variant was added to the range, but it was offered only in certain markets. They all used a dual-mass wheel. In 2012, the fuel injection (piezoelectric) was upgraded to comply with the Euro 5 standard. and the engine was renamed Multijet II.

Almost all of the problems that the old 1.9 JTD was known for don't exist in the lesser 1.6. Users don't have to deal with intake manifold flaps or dirty EGR. Lubrication is also no problem, as in 2.0 Multijet. It is also recommended to change the oil every 15 thousand. km, and not, as the manufacturer suggests, every 35 thousand km. Such a large interval is associated with the risk of clogging the oil dragon and pressure drop.

The only recurring problem with the engine is the DPF filter., but still it causes problems mainly in the city, because people who use the car a lot on the road do not have much trouble with it. An additional benefit of the 1.6 Multijet is that It was not compatible with the not very durable M32 transmission, like the 1.9 JTD.

The 1.6 Multijet engine did not find such acceptance among manufacturers outside the Fiat group. It was only used by Suzuki in the SX4 S-cross (120 hp variant). It can also be assumed that Opel used it in the Combo model, but this is nothing more than a Fiat Doblo. Even within the Fiat group, this engine was not as popular as the 1.9 JTD. It was placed mainly under the hood of B-segment cars (Fiat Punto, Alfa MiTo, Fiat Idea, Fiat Linea, Lancia Mussa), as well as small cars such as Alfa Gliulietta, Fiat Bravo II, Fiat 500 L or Lancia Delta.
