The Fiat 844 A3.000 is a 1,581 cc, inline‑four petrol engine produced between 1993 and 1996. It features a single overhead camshaft (SOHC) design with two valves per cylinder and multi‑point fuel injection. This naturally aspirated unit delivered approximately 76 kW (103 PS) and 137 Nm of torque, providing adequate performance for its era.
Fitted primarily to the Fiat Tempra and Fiat Tipo models, the 844 A3.000 was engineered for dependable, economical motoring with an emphasis on refinement for daily commuting. Emissions compliance for its production period was managed through its electronic fuel injection system and catalytic converter.
One documented service consideration involves the ignition system, specifically premature wear of distributor components. This is noted in Fiat service documentation, where extended intervals or poor-quality parts can lead to misfires or starting difficulties. Regular inspection and replacement with OEM-specified parts are recommended to maintain reliability.
Production years 1993–1996 meet applicable EU emissions standards for that period (VCA UK Type Approval documentation).
The Fiat 844 A3.000 is a 1,581 cc inline‑four petrol engine engineered for compact family sedans and hatchbacks (1993-1996). It combines multi‑point fuel injection with a single overhead camshaft to deliver smooth, predictable power delivery. Designed to meet the emissions regulations of its time, it prioritizes drivability and cost‑effective ownership.

The SOHC design offers simplicity and smooth operation but requires periodic adjustment of valve clearances. The Magneti Marelli IAW injection system is generally robust but relies on clean fuel and a healthy electrical system. Ignition components, particularly the distributor cap, rotor, and HT leads, are common wear items and should be replaced preventatively every 60,000 km. Using the specified 10W-40 oil helps maintain engine longevity. The chain-driven timing system is durable but should be inspected for tension and noise during major services.
Oil Specs: Requires SAE 10W-40 meeting ACEA A3/B3 specification (Fiat Owner's Manual 1994).
Emissions: Meets EU emissions standards applicable to vehicles registered between 1993-1996 (VCA Type Approval Archive).
Power Ratings: Measured under manufacturer's internal dynamometer standards (Fiat Group PT-1995).
Fiat Technical Information System: Manual 844/A3, SIB 0844/93

The Fiat 844 A3.000 was used across Fiat's Tempra and Tipo platforms with transverse mounting. This engine received minor ECU updates during its production run but no major mechanical revisions that affect core compatibility. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front face of the cylinder block, near the gearbox flange (Fiat TIS 844-01). The code "844 A3.000" should be clearly visible. Visually, it can be identified by its black plastic intake manifold and the Magneti Marelli IAW ECU box mounted in the engine bay. Differentiation from the smaller 1.4L (137A) is by displacement and power output; differentiation from the 1.8L (158A) is by bore size and engine code.
The 844 A3.000's primary reliability consideration is ignition system wear, particularly the distributor, with elevated incidence in high-mileage or poorly maintained vehicles. Fiat service data indicates distributor component failure is a leading cause of non-start or misfire conditions. Regular preventative maintenance with quality parts is critical for sustained reliability.
