The Alfa Romeo 936 A.000 is a 1,750 cc, inline-four turbocharged petrol engine produced between 2017 and 2020. It features direct fuel injection, dual variable valve timing (Dual VVT), and a compact turbocharger layout designed for responsive urban performance. In standard tune, it produces 121 kW (165 PS) with peak torque of 240 Nm available from 1,750 rpm, delivering strong low-end pull ideal for city driving.
Fitted to the Alfa Romeo Giulia (952) base trim and the Alfa Romeo Stelvio (956) 2.0 TBi, the 936 A.000 replaced earlier 1.8 TBi units with refinements focused on emissions control and throttle response. It meets Euro 6c standards through a close-coupled three-way catalytic converter and adaptive lambda control, and is longitudinally mounted in rear-wheel-drive and all-wheel-drive configurations. The engine management system uses a Bosch MED 17.8.8 ECU for precise air-fuel metering.
One documented concern is early carbon buildup on intake valves, particularly in vehicles used for frequent short trips. This issue, referenced in Alfa Romeo Service Information Bulletin SIB 56 00 19, stems from the absence of port fuel injection, which prevents fuel washing over intake ports. From 2018, revised intake port geometry and updated ECU mapping were introduced to reduce deposit accumulation under low-load operation.
All production years 2017–2020 meet Euro 6c emissions standards (VCA UK Type Approval #VCA/EMS/6106).
The Alfa Romeo 936 A.000 is a 1,750 cc inline-four turbocharged petrol engine engineered for compact and sporty models (2017–2020). It combines direct fuel injection with dual variable valve timing to deliver responsive throttle characteristics and strong mid-range torque. Designed to meet Euro 6c standards, it balances spirited performance with improved emissions control over previous generations.

The turbocharged design provides strong low-RPM torque ideal for urban driving but requires consistent use of high-octane fuel (RON 98) to prevent knock and maintain ECU performance maps. SAE 5W-40 ACEA A3/B4 oil is essential due to high thermal loads and turbo bearing protection needs. Direct injection contributes to intake valve carbon buildup; periodic induction cleaning is advised per Alfa Romeo maintenance schedules. Post-2018 models feature revised intake port geometry; pre-2018 units are prone to carbon accumulation and should be inspected under SIB 56 00 19. Catalytic converter longevity depends on maintaining proper lambda sensor function and avoiding prolonged misfire conditions. Electric wastegate actuator improves boost control accuracy but requires diagnostic recalibration after replacement.
Oil Specs: Requires SAE 5W-40, ACEA A3/B4 specification (Alfa Romeo SIB 56 00 19). Compatible with API SN and ILSAC GF-5.
Emissions: Euro 6c certification applies to all 2017–2020 models (VCA Type Approval #VCA/EMS/6106).
Power Ratings: Measured under ECE R85 standards. Full output requires RON 98 fuel (Alfa Romeo TIS Doc. A936‑105).

The Alfa Romeo 936 A.000 was used across Alfa Romeo's 952/956 platforms with longitudinal mounting and shared architecture with Fiat Chrysler Automobiles derivatives. This engine received platform-specific adaptations-shorter intake manifolds in the Stelvio and revised engine mounts in the Giulia-and from 2018 the updated intake geometry and ECU calibration were introduced, creating interchange limits. Partnerships enabled Maserati's Levante base trim to use a modified version of this engine. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block, near the exhaust manifold (Alfa Romeo TIS A936‑110). The 8th VIN digit indicates engine type ('B' for 2.0 TBi petrol). Pre-2018 models have silver valve covers with black plastic cam covers; post-2018 units use gloss black valve covers. Critical differentiation from Fiat 1.4 TBi: The 936 A.000 has a larger turbo housing and distinct intake manifold routing. Service parts require production date verification—intake manifolds for pre-2018 engines are incompatible with post-update models due to internal redesign (Alfa Romeo SIB 56 00 19).
The 936 A.000's primary reliability risk is intake valve carbon buildup, with elevated incidence in urban or short-trip driving. Internal Alfa Romeo quality reports from 2019 indicated a significant number of pre-2018 engines required induction cleaning before 80,000 km, while UK DVSA MOT data shows increased emissions-related failures in city-driven examples. Frequent short trips and poor-quality fuel exacerbate carbon buildup, making high-octane fuel and regular highway operation critical for longevity.
