The Lancia 312 A2.000 is a 1,998 cc, inline‑four petrol engine produced between 2003 and 2010. It features a twin‑cam (DOHC) 16‑valve cylinder head and Magneti Marelli IAW 59F electronic fuel injection, delivering responsive performance. The crossflow cylinder head design promotes efficient gas exchange for strong mid-range torque.
Fitted primarily to the Lancia Musa MPV, the 312 A2.000 was engineered for smooth, refined power delivery suitable for urban and family use. Emissions compliance for its era was managed through precise electronic fuel injection and catalytic converter technology, meeting Euro 4 standards for vehicles sold in participating markets.
One documented service consideration is the potential for ignition coil pack failure, which can cause misfires and reduced performance. This is noted in Fiat Group Service Bulletin T.03.10. Specific fault codes often relate to individual coil outputs or the crankshaft position sensor.
Production years 2003–2010 meet Euro 4 emissions standards as per EU Regulation 98/69/EC and subsequent amendments.
The Lancia 312 A2.000 is a 1,998 cc inline‑four petrol engine engineered for compact MPVs (2003-2010). It combines a DOHC 16-valve crossflow head with Magneti Marelli IAW 59F fuel injection to deliver smooth, linear power. Designed to meet Euro 4 emissions standards, it prioritizes refinement and drivability.

The DOHC 16-valve layout provides smooth, linear power ideal for city driving but requires strict 60,000 km timing belt replacement intervals to prevent catastrophic interference engine damage. The Magneti Marelli system is generally robust but can suffer from failing ignition coils or crankshaft position sensors. Premium unleaded fuel (95 RON) is recommended. Regular oil changes with synthetic 5W-40 are essential for maintaining engine health and sensor longevity.
Oil Specs: Requires SAE 5W-40 synthetic oil meeting ACEA A3/B3 or equivalent (Fiat Group Owner's Manual 2004). API SJ/CF minimum.
Emissions: Formal Euro 4 certification applies to all production models (EU Regulation 98/69/EC).
Power Ratings: Measured under DIN 70020 standards. Peak figure is consistent across model years (Fiat Group PT-2004).

Fiat Group Product Technical Specification (PT-2004)
The Lancia 312 A2.000 was used exclusively in the Lancia Musa (Type 312) MPV with transverse mounting. This engine received no major mechanical revisions during its production run, ensuring broad parts compatibility. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Fiat TIS Doc. T.03.01). The 5th and 6th digits of the VIN often indicate engine type for Musa models. Visually, the engine is identified by its twin-cam cover and the Magneti Marelli ECU located in the engine bay. Critical differentiation from diesel variants: the absence of a turbocharger and the specific 2.0 16V badging. Service parts for the ignition and fuel systems are specific to this petrol engine.
The 312 A2.000's primary reliability risk is neglect of the timing belt, with failure resulting in complete engine destruction. Magneti Marelli ignition system faults, particularly coil pack and crankshaft sensor failures, are a documented, common issue. Adherence to maintenance schedules is critical for long-term reliability.
