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.Ī small 1.3 L (1,248 cc (76.2 cu in)) version (called the SDE, Small Diesel Engine) introduced in February 2003 is produced in Bielsko-Biała, Poland, in Ranjangaon, Pune, India, by Fiat India Automobiles and Tata Motors joint venture plant since 2008, and by Maruti Suzuki in Gurgaon, Haryana, India since 2012. 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. 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. In 2009 Fiat Powertrain introduced the third generation of this technology, called Multijet II. 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.

This enables even mid-sized sedans like the Alfa Romeo 156 and Lancia Lybra equipped with the 1.9 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.Ī 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 time between injections has been reduced to 150 microseconds while the minimal injection quantity has been reduced from two to less than one microlitre. 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 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.

Fiat's common rail diesel engine is also known as JTD, an initialism of Jet Turbo Diesel. Some PSA Peugeot Citroën diesel engines are also rebadged JTD units, and vice versa. GM Powertrain Torino group in Turin, Italy manages their interest in these 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.

Most of the Fiat, Alfa Romeo, Lancia range as well as certain Chrysler, RAM Trucks, Jeep and Maserati vehicles are equipped with Multijet engines. Multijet is Fiat Chrysler Automobiles' term for its current common rail direct injection turbodiesel engine range.
