JTD, an initialism for uniJet Turbo Diesel, is Fiat Group's term for its current common rail turbodiesel engine range. The MultiJet name is used in the second generation JTD common rail units. Most of the Fiat, Alfa Romeo and Lancia range has JTD engines. Ownership of some Fiat JTD designs is shared with General Motors as part of a settlement of the failed merger between the two auto conglomerates. GM Powertrain Torino group in Turin, Italy manages their interest in these engines. Some PSA Peugeot Citroën diesel engines are also rebadged as JTD.

A new generation JTD engine, Multijet II was introduced in Fiat Punto Evo in 2009.

Italian FNM is marinizing Fiat diesel engines like the four cylinder 1.9 L and five cylinder 2.4 L for boat propulsion, they are producing between 60-295 hp.[1]

1.3[edit]

A small 1.3 L (1,248 cc) version (called the SDE, Small Diesel Engine) is produced in Bielsko-Biała, Poland and in Ranjangaon, Pune, India by Fiat India Auto.[2] The Multijet 75 PS version was chosen in 2005 as the International Engine of the Year in the 1-litre to 1.4-litre category.

There are four versions of this engine: a 70 PS (51 kW; 69 hp), a 75 PS (55 kW; 74 hp) (used in the Fiat Punto, Panda, Palio / Albea, Fiat Idea, Opel Corsa / Combo, Opel Meriva, Suzuki Ritz, Suzuki Swift), a variable inlet geometry 90 PS (66 kW; 89 hp) (used in the new Fiat Grande Punto, Fiat Linea, Suzuki Ertiga, Opel Corsa, Opel Astra and Alfa Romeo MiTo), and a 105 PS (77 kW; 104 hp) is available to Lancia Ypsilon. At the time of the launch this was the smallest four-cylinder diesel engine available and has a fuel consumption of 3.3 L/100 km (86 mpg-imp; 71 mpg-US) in some applications. The engine is able to meet Euro IV pollution standards without the use of a diesel particulate filter.

In January 2008 Tata Motors introduced new Indica Vista model, which features new QuadraJet branded version of this engine.[3] The second generation Ford Ka uses 1.3 Multijet named as Duratorq TDCi .

During 2009 Fiat launched a new generation badged Multijet 2, with a new injection management system (up to 8 injections per cycle, instead of 5) and able to meet Euro V pollution standards. It is available with several power outputs: from 75 PS (55 kW; 74 hp), with fixed geometry turbocharger, to 95 PS (70 kW; 94 hp), with variable geometry turbocharger.[4]

The engine is called Small Diesel Engine in GM nomenclature.

As of 2013, more than 5 million 1.3 MultiJet engines were produced.[5]

1.6[edit]

A 1.6 L (1,598 cc) version of the engine, with a maximum power output of 120 PS (118 hp/88 kW) was announced for 2006.[6] The new 1.6 JTD diesel (105 PS) was released December 2007, it came in spring 2008 as 120 PS version.[7]

The most common JTD engine is the 1.9 L (1,910 cc, 82 mm bore, 90.4 mm stroke) straight-4 found on various brands and models. The first car that used this engine was Alfa Romeo 156 in 1997 (105 PS or 77 kW; 104 hp), making it the world's first common-rail Diesel passenger car. In 1999 it was introduced with the Fiat Punto (81 PS or 60 kW; 80 hp) and Fiat Brava/Bravo/Marea. There were also 85 PS (63 kW; 84 hp), 100 PS (74 kW; 99 hp), 110 PS (81 kW; 110 hp) and 115 PS (85 kW; 113 hp) versions available. The engine block weighs approximately 125 kg (276 lb).

The Multijet second generation features a common-rail design and is available with five different power outputs. The 8-valve version has 100 PS (74 kW; 99 hp), 120 PS (88 kW; 120 hp) or 130 PS (96 kW; 130 hp), the last two with variable geometry turbocharger; and the 16-valve version has 150 PS (110 kW; 150 hp) or 170 PS (130 kW; 170 hp).

Opel also uses a version of this engine. Their CDTI engine, manufactured in Pratola Serra, Italy and Kaiserslautern, Germany, is the product of the half-decade joint venture between GM and Fiat. It is used in the Vectra, Signum, Astra, Zafira, Cadillac BLS and Suzuki SX4 as well as some Saabs marked as TiD and TTiD (twinturbo version).

Applications:

  • Right side view, from Saab 9-5

  • Left side view, from Saab 9-5

  • Dual overhead camshaft housing

  • Turbo charger with attachments from 9-5

A new 2 litre (1,956 cc, 83 mm bore, 90.4 mm stroke) Multijet diesel was introduced in third generation Lancia Delta in summer 2008. At its first version this engine produces 165 PS (121 kW; 163 bhp). For 2009 the engine was fitted to Alfa Romeo 159 as 170 PS (125 kW; 168 hp) variant. Fiat Sedici, Suzuki SX4 and the new Fiat Doblò generation use a 135 PS (99 kW; 133 hp) variant of this engine.

GM Powertrain also developed [10]a 165 PS (121 kW; 163 bhp) version for Astra and Insignia.

Internally the new engine is referred to as GM Family B engine. The same engine was also available in the 2011 Saab 9-5 with 160 PS and 190 PS twin-turbo, and in 2012 Chevrolet Malibu with single turbine - 160 PS.

Applications:

The 2.4 L (2,387 cc) straight-5 version is based on the 2.4 124 PS (91 kW; 122 hp) 5 cylinder TD engine as used in the Mk1 Fiat Marea and the Mk1 Lancia Kappa. The JTD version benefits from the solid build of the TD block, and an improved head/injection system. There are 2 versions of the 2.4 JTD, the 10-valve as used in the Fiat Marea 130 JTD and the earlier Alfa Romeo 156 diesels where it was available as 136 PS (100 kW; 134 hp),140 PS (103 kW; 138 hp), 150 PS (110 kW; 148 hp) and later a Multijet 20-valve version 175 PS (129 kW; 173 hp) as used in the later (2003>) Alfa Romeo 156 as well as some Lancia vehicles.

It was designed for transverse front-wheel drive use and was deemed too long and tall for widespread use in other GM or Fiat products. A newer Multijet variant of this engine, capable for 200 PS (147 kW; 197 hp), is currently used in the Alfa Romeo 159, Alfa Romeo Brera and Fiat Croma. The latest version of this engine produces 210 PS (154 kW; 207 hp) and 400 N·m (295 lb·ft) at 1500 rpm, and is used in Alfa Romeo vehicles.[11]
