Fiat displays at the Geneva Motor Show 2010 (4th is until 14 March) for the first time from autumn 2010, first offered exclusively in the Fiat 500 Twin-air engine, the harbinger of a new engine series. The equipped with a turbocharged two-cylinder gasoline engine making 63 kW and will emit less than 100 grams of CO2 per kilometer.
Developed by Fiat Powertrain Technologies (FPT), twin-cylinder gasoline engine with turbocharger has the Multiair technology, in which the intake camshaft is replaced by an electrohydraulic system. Thus, a fully variable, the respective loading condition of the engine allows optimally adapted valve timing.
The twin-Series Twin-Air, which will be the medium with outputs between 48 kW and 77 kW are available, waiting with up to 30% less consumption than a comparable four-cylinder. For the future, offered in the Fiat 500 variant, which develops 63 kW engine capacity of 900 cubic centimeters, Fiat expects to CO2 emissions of 95 g/km. An even more significant reduction in emissions (minus ten percent) will be achieved by future natural gas version of this engine.
The compact design of the new-cylinder, turns out the 23 percent shorter and ten percent lighter than a comparable four-cylinder, also enables the combination of alternative propulsion technologies. Thus, according to the Italian car manufacturer, the coupling with an electric motor or a system for recovering energy during braking, compared to a four-cylinder natural space requirements represented.
