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, MI (only in 1.4 Multiair versions) plants. 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 100 series overhead valve engines in the mid-1980s. Mechanically, they are simple inline-four engines with five main bearings crankshaft and overhead cam heads.
Since 1985, it has been constructed in different versions. Displacements range from 769to. In addition to the 8 valve versions, there are "Super-FIRE" 1242and 16 valve versions.
The "Super-FIRE" which uses 16 valves and is available in 999cc (Brazil) and 1242cc (Brazil & Europe) displacements.
The 1368cc variation introduced in 2003 is available in both 8 and 16 valves. In 2005 Fiat introduced a version of the 16v incorporating port deactivation (PDA) and exhaust gas recirculation (EGR). This unit is frequently referred to as the "StarJet" engine. One year later, a turbocharged variety of the StarJet was introduced under the name "T-Jet", and a MultiAir (adding electro-hydraulic intake valve driving, with variable timing, lift and profile) version was added in 2009, available in either naturally aspirated and turbocharged forms. It reached 190 PS on the Abarth 695 Biposto.
The FIRE was originally a carbureted engine, and later progressed to single-point injection (SPI), then to multi-point fuel injection (MPI), using sequential multi-port fuel injection (SMPI) today. It is now used in the 750 Formula in a slightly modified state.
Brazilian production started in 2000 with the "Super-FIRE" 1.2 16V (80 PS), was extended until 2006 with 1.0 8V (54 PS), 1.0 16V (69 PS), 1.2 8V (66 PS) and 1.4 8V (80 PS). By 2016, the two "last Super-FIRE" being produced in Brazil were the reworked (New pistons and crankshaft) 1.0 8V (77 PS) and the 1.4 8V VVT (90 PS), both running on petrol or ethanol fuels.
Starting in 2016, it is being replaced by the GSE (FireFly) engine family.
The FIRE engine has been available in the following displacements:
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 100hp 1.4-liter FIRE with Multiair engine, was first introduced in Fiat 500 starting in 2010.[4]
