The Lancia ENS is a 1,368 cc, inline‑four turbocharged petrol engine produced between 2007 and 2011. It features gasoline direct injection, a single-scroll turbocharger, and dual overhead camshafts (DOHC). This engine delivered 120 kW (163 PS) and 250 Nm of torque, with its direct injection system enabling strong low-rpm response for urban drivability.
Fitted primarily to the Delta III (844) platform, including the 1.4 Turbo variant, the ENS was engineered for a blend of spirited performance and refined cruising. Emissions compliance was achieved through a three-way catalytic converter and electronic throttle control, meeting Euro 5 standards across its production run.
One documented engineering update addressed potential carbon buildup on intake valves, a known characteristic of early direct injection systems. This was mitigated through revised engine management calibration, as detailed in Lancia Service Bulletin LB‑08‑11, to optimize injector spray patterns and combustion efficiency.
Production years 2007–2011 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Lancia ENS is a 1,368 cc inline‑four turbocharged petrol engine engineered for compact hatchbacks (2007-2011). It combines gasoline direct injection with a single-scroll turbocharger to deliver responsive performance and efficient cruising. Designed to meet Euro 5 standards, it balances sporty character with everyday usability.

The turbocharged direct injection provides strong mid-range torque ideal for overtaking but requires premium unleaded fuel (95 RON minimum) to prevent knock and carbon buildup. Lancia 5W-40 (ACEA C3) oil is critical for turbocharger and timing chain longevity. Extended oil change intervals beyond 15,000 km may accelerate intake valve deposits, necessitating periodic cleaning. The engine management system includes adaptive learning; battery disconnection requires throttle body adaptation via diagnostic tool per Lancia SIB LB-08-11.
Oil Specs: Requires Lancia 5W-40 (ACEA C3) specification (Lancia Owner's Manual). Compatible with Fiat 9.55535-S2.
Emissions: Euro 5 certification applies to all 2007-2011 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output requires 95 RON fuel (Lancia TIS Doc. L90015).

The Lancia ENS was used across Lancia's Delta III (844) platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts and a unique exhaust manifold layout. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the gearbox flange (Lancia TIS L88900). The 8th VIN digit typically corresponds to the engine type ('B' for ENS). Visually, the engine is identifiable by its black plastic intake manifold and the '1.4 Turbo' badge on the engine cover. Critical differentiation from naturally aspirated engines: ENS features a visible turbocharger and intercooler piping. Service parts are generally consistent across the production run, but ECU software versions vary; always verify part numbers against the vehicle's build date.
The ENS's primary reliability consideration is carbon buildup on intake valves, a trait of its direct injection system, particularly with low-speed, short-trip driving. Lancia service data indicates this is a maintenance item rather than a failure, while UK DVSA records show no significant pattern of related MOT failures. Regular highway driving and adherence to fuel/oil specifications make proactive maintenance manageable.
Analysis derived from Lancia technical bulletins (2008-2012) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
