Alfa Romeo is introducing a new turbo-diesel engine from the MultiJet II series for the MiTo in the UK market. The MiTo 1.3 MultiJet II comes standard with Start&Stop system and features a Diesel Particulate Filter, and as a result fully complies with Euro 5 standards while delivering 95 bhp.
With only 95 bhp, the MiTo can do zero to 60 mph in 11.6 seconds which is really slow, but in return you get astonishing fuel economy as the car averages 65.7 mpg while emitting just 112g/km of CO2. The car is available with three trim levels: Turismo, Lusso and Veloce.
Introduced in 2003, MultiJet was a development of UniJet which debuted on the Alfa 156 JTD in 1997. It improved the thermodynamic efficiency of the engine by introducing five injections during the same combustion cycle. Now in 2010 the Alfa MiTo benefits from the next generation of MultiJet technology.
Thanks to a new balanced solenoid servo valve, MultiJet II is able to control with high precision, the quantity of fuel injected into the cylinder, with a quicker and more flexible injection sequence. In fact, the new MultiJet II system can manage eight injections per cycle. It also offers higher flexibility in managing multiple injections, resulting in further optimisation of diesel combustion. In particular it has a new injection modality called Injection Rate Shaping (IRS) which consists of two consecutive injections with zero hydraulic dwell. This has a positive effect on combustion at higher loads, allowing for improved trade-off in terms of emissions, fuel consumption and noise.
