The FIRE (for "Fully Integrated Robotised Engine") is a series of automobile engines from Fiat Powertrain Technologies, built in FCA's Termoli, Betim and also in Dundee (only in 1.4 Multiair versions) plants. It was designed by Italian design firm Rodolfo Bonetto. It is constructed by robot assembly plants ("Robogate") to reduce costs.
Contents
The FIRE series replaced the old Fiat 100 series OHV engines in the mid-1980s. Mechanically, they are simple straight-4 engines with five main bearings crankshaft and overhead cam heads.
Since 1985, it has been constructed in different versions from 769 cc to 1368 cc with 8 valves; there is another version called the "Super-FIRE" which uses 16 valves and is available in 999 cc (Brazil) and 1242 cc (Brazil & Europe) displacements.
The 1368 cc variation introduced in 2003 is available in both 8 and 16 valves; in 2005 Fiat introduced a version incorporating port deactivation (PDA) and EGR. This unit is frequently referred to as the "Starjet" engine. In 2005, a turbocharged version of 1368 cc was introduced as "T-Jet" engine, and a MultiAir (electro-hydraulic intake valve driving, with variable timing, lift and profile) version, available in either naturally aspirated and turbocharged versions, was added in 2009.
The FIRE was originally a carburetor engine, and later progressed to single point injection (SPI), then to multipoint injection (MPI), using sequential multipoint injection (SMPI) now. It is now used in the 750 Formula in a slightly modified state.

Production
As part of the June 10, 2009 Operating Agreement, Chrysler's commercial production of Fully Integrated Robotized Engine began in its Dundee, Michigan facility. Chrysler's first FIRE engine model, a 100 hp 1.4-liter FIRE with Multiair engine, was first introduced in Fiat 500 starting in 2010.
