The 900 cm3 Twin Air engine, which has recently been released in Bielsko-Biała, originally found under the bonnet of the Fiat 500. Therefore, the Italian concern returns to two cylinder engines.
Production of these units was launched in June at the Fiat Powertrain Technologies plant in Bielsko-Biała. The Italians have invested around 300 million EUR in it, and the full production capacity will be 450,000 units per year.
The engine is designed with an electro-hydraulic system for controlling the Multiair intake valves and a chain-driven timing gear. A lot of work has been done to reduce the powerful vibrations typical of a two-cylinder engine. For this purpose, an intermediate countershaft is used.
Depending on the version – with or without a turbine, or powered by CNG natural gas – the TwinAir engine can be powered from 65 to 105 HP. These are impressive figures for a unit with a capacity of only 900 cm3. The 85 HP turbo version makes its debut under the hood of the Fiat 500. It is certain that this is a record engine when it comes to ecology. Carbon dioxide emissions were reduced to PLN 0.15/km.
The two-cylinder engine in the Fiat 500 is available with the fuel-saving Start & Stop system, which controls when to turn off the engine in traffic jams or traffic lights. According to the manufacturer, it saves an additional 12 percent of fuel when driving in the city. The ecodrive system, i.e. a special program, which, through the USB port in the Blue & Me system, allows the driver to make a computer analysis of how the car is driven, helping him save extra liters of fuel, is also helpful. reduce fuel consumption.
A car with this engine accelerates to “hundreds” in 11 seconds, and the maximum speed is 173 km / h. According to the manufacturer’s data, the average consumption of gasoline in the combined cycle should not exceed 4.1 l per 100 km. The version working with the Dualogic automatic gearbox is even less burning.
The ECO button on the dashboard helps save fuel. The Twin Air engine develops a maximum torque of 145 Nm. By pressing the ECO button, the torque delivered to the wheels is reduced to 100 Nm at 1,750 rpm. Then the car uses less fuel, but at the cost of deterioration of driving dynamics.
For now, Fiat representatives did not want to reveal which models of the concern will include Twin Air engines. “Pięćsetka” with these units will go on sale in Poland in September. So for now, we only know the price on the Italian market: EUR 13,250, or about PLN 53,900.
