Fiat launches new MultiAir engines

By Tim Pollard Motor Industry 09 March 2009 14:02 Fiat showed off the detail of its new MultiAir engines at the 2009 Geneva motor show – and we’ll finally be able to buy the tech on the new Alfa Romeo Mito supermini later in 2009. The brains behind the common-rail injection system that shook up diesel technology have now produced a new technology designed to make petrol engines more efficient and cleaner. Engineers claim the MultiAir engines – which use electrohydraulic actuation, rather than the more widely available electromechanical systems – boost power and torque, while cutting CO2 by between 10% and 25% and other pollutants by up to 60%.
