Fiat announced today, a new 1.3L diesel engine to meet European standards. At the time of this post it is not known if there are plans to bring this new Fiat diesel engine to America. This engine is designed and produced by Fiat Power Train technologies and comes in at 95 hp and is designated the 1.3 Multijet II. This new variant has new common rail injectors, as well as a few other tweaks to the combustion chamber to enhance the speed and efficiency of the injection cycle. This allows better power, and less diesel consumption.
The new 95 HP engine on the Fiat 500 and 500C is equipped with a variable geometry turbocharger that ensures optimum turbocharging throughout the entire operating range. Fuel consumption has been reduced by up to 8% in the urban cycle thanks also to the Start&Stop system that switches the engine off temporarily and then restarts it.
With Euro 5 type-approval, the new 1.3 liter engine enhances its environmentally-friendly pedigree further through the particulate filter (DPF) integrated in the engine compartment which improves its efficiency even more, especially in the first few moments after cold starting.
The second generation Multijet power units represent the development of the common rail injection system which today, after the JTD (1997) and Multijet (2003) engines, allow Fiat Group Automobiles to steal a march in this field and be prepared for future regulations. The Multijet II engines use increasingly advanced "strategies" to improve combustion: for example, the use of injection rate shaping (two consecutive injections with no hydraulic interval) reduces noise, fuel consumption and, in view of Euro 6, harmful emissions (a potential 30% reduction of nitrogen oxides).
Lastly, together with the new 1.3 Multijet II 95 HP engine, the new rear torsion beam (semi-independent) suspension with an anti-roll bar is also making its debut on the Fiat 500 range. It is derived from the Abarth 500 model and has already made an appearance on the 500C. It gives better handling and a more comfortable ride.
