Multijet is Fiat and General Motors joint venture in manufacturer since 1996 common rail direct injection turbo diesel diesel engine technology. Most of the Fiat S.p.A., Fiat Professional, Groupe PSA (Peugeot and Citroen), Alfa Romeo, Maserati, Lancia, Chrysler, Chevrolet, Daewoo Motors, Cadillac, Karsan, Temsa, Iveco, Jeep, Opel, Vauxhall Motors, RAM Trucks, Mitsubishi Fuso, Maruti Suzuki, Suzuki, Tata Motors and Saab Automobile branded vehicles are equipped with Multijet engines. Ownership of some Fiat Multijet designs is shared with General Motors as part of a settlement of the failed merger between the two auto conglomerates. The GM Powertrain Torino group in Turin, Italy, manages its interest in these engines. Some PSA Peugeot Citroën diesel engines are also rebadged JTD units, and vice versa.^{[citation needed]} Fiat's common-rail diesel engine is also known as JTD, an initialism of UniJet Turbo Diesel.^[1]

Characteristics

The property that distinguishes the Multijet from previous generations of common-rail diesel engines from FCA is the combustion of the fuel, which is split into multiple injections, thus allowing for a more complete, quieter combustion in the cylinder. Compared to the first-generation JTD engines (Unijet system) which only featured a smaller pilot and a larger main injection, Multijet is capable of up to five injections per combustion cycle which enables better, more efficient cold running, better performance especially in the lower rev-range, quieter operation as well as even lower consumptions and emissions. The time between injections has been reduced to 150 microseconds while the minimal injection quantity has been reduced from two to less than one microlitre. This enables even mid-sized sedans like the Alfa Romeo 156 and Lancia Lybra equipped with the 1.9L JTD to achieve fuel economy upwards of 45 mpg_US (55 mpg_imp or 5L/100 km) on country roads and highways while offering an equal amount of torque as the 3.0L 24V V6 engine. A sophisticated electronic control unit controls the injection and changes the injection logic and number of injections based on a multitude of parameters, most importantly revolutions per minute of the engine, engine torque requested by the driver and the temperature of the coolant. The injection pressure of the diesel fuel on the second-generation Multijet is limited to between 1,400 bar (20,000 psi) on the 1.3 Multijet and 1,600 bar (23,000 psi) on the 2.4 Multijet 20V.

Multijet II

In 2009, Fiat Powertrain introduced the third generation of this technology, called Multijet II. With its new and innovative injectors with hydraulically balanced solenoid valve and even higher injection pressure of 2,000 bar (29,000 psi) it is capable of even more precise controlling of the injected diesel fuel, injecting it in a quicker and more flexible manner. It enables up to eight consecutive injections per combustion cycle and implemented Injection Rate Shaping technology, which provides two very close pilot injections making the fuel delivery more continuous and modulated.^[2] This results in an engine that is quiet and has a smoother operation, lower emissions, better fuel mileage and higher performance compared to the previous generation.

A small 1.3 L (1,248 cc (76.2 cu in)) version (called the SDE, Small Diesel Engine) introduced in February 2003^[4] is produced in Bielsko-Biała, Poland,^[5] in Ranjangaon, Pune, India, by Fiat India Automobiles and Tata Motors joint venture plant since 2008,^[6] and by Maruti Suzuki in Gurgaon, Haryana, India since 2012.^[7][8] 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 five versions of this engine: a 70 PS (51 kW; 69 hp) and a 75 PS (55 kW; 74 hp) (used in the Punto, Panda, Doblo, Palio, Albea, Idea, 500; Opel Corsa, Combo, Meriva; Suzuki Ritz, Swift; and Tata Indica Vista), a 85 PS (63 kW; 84 hp) (used in the Fiat 500L and Fiat Doblo), a variable inlet geometry 90 PS (66 kW; 89 hp) (used in the Fiat Grande Punto,^[9] Linea; Opel Corsa, Astra; Suzuki Ertiga, SX4; Tata Indigo Manza and Alfa Romeo MiTo) and a 95 PS (70 kW; 94 hp) from the Multijet II generation,^[10] and a 105 PS (77 kW; 104 hp) available on the Lancia Ypsilon. Newton metre torque in the 180 N⋅m (133 lb⋅ft), 190 N⋅m (140 lb⋅ft), 200 N⋅m (148 lb⋅ft) and 210 N⋅m (155 lb⋅ft). At the time of the launch this was the smallest four-cylinder diesel engine available and had 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.^[10] In January 2008, Tata Motors introduced the new Indica Vista model, which features new Quadrajet branded version of this engine.^[11] The second generation Ford Ka uses 1.3 Multijet named as Duratorq TDCi. In GM nomenclature, it is called Small Diesel Engine (SDE). During 2009, Fiat launched a new generation badged Multijet II, with a new injection management system (up to 8 injections per cycle, instead of 5) and able to meet Euro V pollution standards.^[12] 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.^[13] As of 2013, more than 5 million 1.3 MultiJet engines were produced.^[14] In January 2020, the production of the 1.3 Multijet ended in India in both Maruti Suzuki plant and Fiat-Tata JV as the BS6 emission regulations come into effect in the country from 1 April 2020.^[15] Fiat-Tata built a total of 800,048 engines over 12 years.^[16]
