Calling Fiat’s MultiAir (earlier post) “the single most innovative engine technology to appear in the past 12 months”, the Awards judging panel for the International Engine of Year Awards has selected the 1.4L Multiair Turbo the Best New Engine of 2010.
MultiAir employs an electrohydraulic system to independently control each cylinder’s inlet air charge. Depending on the driving situation, there are five main modes of inlet valve timing and lift, but in principle MultiAir enables infinitely variable control of the inlet valves.
The system enables the delivery of increases power and torque while reducing fuel consumption and emissions. Fiat Powertrain Technologies, which developed and patented the system, claims that, compared with a traditional gasoline engine of the same displacement, a MultiAir unit brings up to 10% more power and 15% more torque, while improving fuel economy by up to 10% and reducing emissions, whether they be CO2 (-10%), particulate matter (-40%) or NOx (-60%).
Fiat plans to roll MultiAir out across additional engine families, with the next to benefit being an anticipated two-cylinder turbo, which is on track to offer 105 bhp, the panel noted.
The Green Engine of the Year Award went to Toyota for the new 1.8L Atkinson-cycle unit in the new Prius and in the Auris. Other award-winning engines included:
