The Lancia 198 A2.000 is a 1,998 cc, inline‑four petrol engine produced between 1995 and 2000. It features a twin‑cam (DOHC) design and multi‑point electronic fuel injection, delivering refined power and improved emissions for its era. The aluminium alloy block and head construction maintained a favorable power-to-weight ratio for agile handling.
Fitted primarily to the Lancia Delta and Zeta, the 198 A2.000 was engineered for spirited performance and responsive driving. Emissions compliance for its production period was achieved through precise electronic fuel injection and catalytic converter integration, meeting Euro 2 standards.
One documented engineering concern is premature failure of the camshaft position sensor, which could lead to intermittent engine stalling or failure to start. This was addressed in Lancia service documentation, recommending specific sensor replacement procedures and the use of updated sensor components for affected vehicles.
Production years 1995–2000 meet Euro 2 standards (Italian Ministry of Transport Type Approval).
The Lancia 198 A2.000 is a 1,998 cc inline‑four petrol engine engineered for performance hatchbacks and sedans (1995-2000). It combines dual overhead camshafts with multi-point electronic fuel injection to deliver responsive power and meet emissions targets. Designed to meet Euro 2 standards, it balances performance with regulatory compliance.

The DOHC 16-valve design provides responsive, high-revving power ideal for spirited driving but demands strict adherence to the 60,000 km timing belt replacement interval to prevent catastrophic engine failure. SAE 10W-40 mineral oil is specified for its balance of protection and flow. The documented camshaft position sensor issue necessitates using the updated OEM sensor component during replacement to ensure reliable engine operation.
Oil Specs: Requires SAE 10W-40 mineral oil specification (Lancia Owner's Manual, Delta 1996). Modern synthetic equivalents meeting API SG/CD or earlier are often used.
Emissions: Euro 2 certification applies to all 1995-2000 models (Italian Ministry of Transport Type Approval).
Power Ratings: Measured under period-typical standards (e.g., DIN 70020). Figures are net power as installed in vehicle (Lancia Type Approval Documentation 1995).

The Lancia 198 A2.000 was used across Lancia's Delta and Zeta platforms with transverse, front-engine, front-wheel-drive mounting. This engine received minor platform-specific adaptations for ancillary drive layouts and engine management harness routing. All adaptations are documented in OEM technical bulletins.
Locate the engine type code stamped on a flat boss on the cylinder block, typically near the oil filter or on the front face adjacent to the water pump (Lancia Workshop Manual 837). The code "198 A2.000" should be clearly visible. Visually, it is identifiable by its twin camshaft covers and the multi-point fuel injection rail on the intake manifold. Differentiation from the 8-valve engines is by the valve cover design and the number of intake runners. Service parts for the camshaft position sensor require verification of the correct updated part number as per Lancia Technical Bulletin.
The 198 A2.000's primary reliability risk is camshaft position sensor failure, leading to drivability issues and potential immobilization. Lancia service data indicates this was a prevalent electrical concern in mid-life examples. Adherence to using the updated OEM sensor during replacement is critical to prevent recurring faults.
