New Multiair Diesel Engine Technology Breakthrough From FIAT

Tech means more power, less fuel, lower emissions

Fiat Group has just launched MultiAir, a fundamental breakthrough in petrol engine design that will dramatically cut fuel consumption, as well as significantly boosting power and torque, cutting carbon dioxide emissions by between 10 and 25 per cent, and up to a 60 per cent reduction in other engine pollutants.

With MultiAir, Fiat has brought together the company’s enviable expertise and technology to make one of the single largest leaps forward for petrol engine design in recent times.

MultiAir Technology benefits:

* Maximum power is increased by up to 10 % thanks to the adoption of a power-orientated mechanical camshaft profile.
* Low RPM torque is improved by up to 15 % through early intake valve closing strategies that maximise the air mass trapped in the cylinders.
* Elimination of pumping losses brings a 10 % reduction in fuel consumption and CO2 emissions.
* Optimum valve control strategies result in emissions reductions ranging from 40 per cent for unburnt hydrocarbons and carbon monoxide (HC/CO), and up to a 60 per cent cut in oxides of nitrogen, (NOx).
* Superior dynamic engine response, and enhanced driving pleasure.
* Applicable to all internal combustion engines, regardless of the fuel used.
* Can be adapted for diesel engines to reduce their NOx emissions and make particulate filters significantly more effective.
