The Lancia 841 A.000 is a 1,995 cc, inline‑four petrol engine produced between 1985 and 1992. It features a twin‑cam (DOHC) cylinder head and electronic fuel injection, delivering a balance of performance and refinement for its era. Its 16‑valve configuration enabled higher revs and improved volumetric efficiency compared to contemporary SOHC designs.
Fitted primarily to the Lancia Thema 8.32 model, the 841 A.000 was engineered to offer a sporty and refined driving character derived from Ferrari's 308/328 V8 architecture. Emissions compliance for its production period was managed through its precise fuel injection system and exhaust catalyst, meeting prevailing Euro 1 standards.
One documented engineering consideration is the complexity of the timing belt system, which drives both camshafts and requires precise tensioning. This design, highlighted in Lancia service documentation, necessitates strict adherence to replacement intervals to prevent potential interference engine damage.
Production years 1985–1992 meet Euro 1 standards as per prevailing EU regulations at time of manufacture (EU Directive 88/77/EEC).
The Lancia 841 A.000 is a 1,995 cc inline‑four petrol engine engineered for executive sedans (1985-1992). It combines a DOHC 16-valve cylinder head with Bosch L-Jetronic fuel injection to deliver a high-revving, sporty character. Designed to meet Euro 1 emissions standards, it prioritized performance while adhering to regulatory requirements of its era.

The high-revving nature provides a sporty feel but necessitates strict 60,000 km timing belt replacement intervals to prevent catastrophic engine failure in this interference design. Using the specified 10W-40 oil is critical for maintaining hydraulic tappet function and camshaft lubrication. The Bosch L-Jetronic system requires clean fuel and functioning sensors; degraded oxygen sensors or fuel injectors will significantly impact performance and emissions. The complex belt routing demands specialist tools for correct tensioning during service.
Oil Specs: Requires SAE 10W-40 specification (Lancia Owner's Manual). ACEA A3/B3 or equivalent API rating recommended.
Emissions: Euro 1 certification applies to all 1985–1992 production (EU Directive 88/77/EEC). No market-specific variations documented.
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across all model years (Lancia Tech Spec Sheet).

The Lancia 841 A.000 was used exclusively in the Lancia Thema platform with longitudinal mounting and was not licensed to other manufacturers. This engine was a unique feature of the high-performance Thema 8.32 variant, sharing its cylinder head design with Ferrari's contemporary V8 engines, creating a distinct model within the Thema range. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, just below the cylinder head (Lancia TSB 841/1). The vehicle's VIN will correspond to the Thema 8.32 model. Visually, the engine is identifiable by its red-painted camshaft cover and the "8.32" badge on the boot lid and front wings. Critical differentiation from standard Thema engines: The 841 A.000 has a distinctive intake manifold and a unique distributorless ignition system with individual coil packs. Service parts, particularly the timing belt kit, are specific to the 8.32 and not interchangeable with other Thema petrol engines.
The 841 A.000's primary reliability risk is timing belt failure due to age or missed service intervals. Lancia service data indicates that neglecting the 60,000 km replacement can lead to total engine destruction. The engine's interference design and complex belt routing make adherence to the maintenance schedule critical.
