Report on Operations
For diesel engines, the MultiJet II’s Injection Rate Shaping (IRS) technology, which proved highly successful on the Fiat Punto and Alfa
Romeo MiTo, is now also available on the Fiat 500L with the new 85 hp 1.3-liter MultiJet II equipped with eco-Turbo. The principal
advantage of MultiJet II engines is that they offer reductions in fuel consumption (up to 3%) and polluting emissions (up to 20% NOX
7),
while maintaining performance through the use of advanced combustion control strategies.
Research in diesel engine technology is primarily focused on achieving further reductions in polluting emissions, NOX in particular,
surpassing the minimum Euro6 emissions requirements through the optimization of engine control strategies for injection and
combustion processes.
In the area of transmissions, the Dual Dry Clutch Transmission (DDCT) already available on the Alfa Romeo MiTo and Giulietta was
adapted for application on the Dodge Dart and Fiat Viaggio launched, respectively, in the North American and Asian markets during
2012.
Research activities in this area are focused on optimizing dual clutch transmission systems through the development of integrated
engine, transmission and vehicle control strategies that will bring benefits in terms of drivability and fuel economy.
