Fully Integrated Robotized Engine

The FIRE engine (for "Fully Integrated Robotized Engine") is a series of engines from Fiat Powertrain Technologies . The Italian design office Rodolfo Bonetto was involved in the construction. The motor was assembled fully automatically on a robot line (“Robogate”), which made it cheaper to manufacture than its predecessor.

In the mid-1980s, the FIRE replaced the small Fiat OHV engine, which in its main features can be traced back to the engine of the Fiat 600 . The FIRE is a 4-cylinder in-line engine with five main bearings, a cast iron block and a timing belt-driven overhead camshaft in a light metal cylinder head with parallel hanging valves and bucket tappets .

The engine has been built in various versions since 1985, with displacements from 769 to 1368 cm³ with eight valves and in the so-called "Super-FIRE" version with 16 valves with 999 cm³ (Brazil) and 1242 cm³ (Brazil and Europe).

The engine was introduced in the Y10 (1985) of the Fiat subsidiary Lancia, followed by the Fiat Uno (1985) and Fiat Panda (1986).

The 1368 cc version, which was introduced in 2003, is available with both eight and 16 valves; In 2005 Fiat presented a version with variable intake manifold and exhaust gas recirculation . This engine is commonly called the “Starjet” engine. Also in 2005, a turbocharged 1368 cc version called the “T-Jet” engine was introduced, followed in 2009 by an engine with the Multiair electro-hydraulic valve control system .

The mixture of the FIRE initially came from a single Weber carburetor. Over the years, the engine was equipped with manifold injection and gradually developed into SPI (one-point injection), MPI (multi-point injection) and, most recently, SMPI (sequential multi-point injection). The FIRE engine is currently used in the Formula 750 in a slightly modified version.

use

production

As part of the 2009 company agreement, Chrysler began commercial production of the FIRE at its Dundee, Michigan facility. Chrysler's first FIRE variant, a 100 hp 1.4 liter FIRE Multiair, was first introduced in the 2010 Fiat 500.
