The FIRE (for "Fully Integrated Robotised Engine") is a series of automobile engines from Fiat Powertrain Technologies. It was designed by Italian design firm Rodolfo Bonetto.[1] It is constructed by robot assembly plants ("Robogate") to reduce costs.

The FIRE series replaced the old Fiat OHV engine in the mid-1980s. Mechanically, they are simple straight-4 engines with five bearings 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 valve) version was added in 2009.

The FIRE was originally a carburetor engine, and later progressed to a single point injection (SPI), then to multipoint injection (MPI) and is now a sequential multipoint injection (SMPI). 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.[2][3] 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.[4]
