The Mitsubishi 4N13 is a 2,268 cc, inline‑four turbo‑diesel engine produced between 2010 and 2023. It features a double overhead camshaft (DOHC), 16 valves, and a high-pressure common-rail fuel system with piezo injectors. In standard form it delivered 110–135 kW (150–184 PS) and 360–400 Nm of torque, engineered for refined performance and emissions compliance in global SUV and pickup applications.
Fitted to models such as the ASX, Outlander, and L200, the 4N13 was developed under the Mitsubishi–Renault–Nissan alliance and shares core architecture with the Renault R9M engine. Emissions compliance was achieved through exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC), diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue in later variants, allowing Euro 5 and Euro 6 compliance across its production run.
One documented concern is premature failure of the high-pressure fuel pump drive coupling, which can cause loss of rail pressure and engine limp mode. This issue, highlighted in Mitsubishi Technical Service Bulletin TSB‑ME‑12‑044, is linked to torsional stress in the camshaft-driven pump coupling under thermal cycling. From 2016 onward, Mitsubishi introduced a reinforced coupling and updated camshaft gear profile to mitigate the fault.
Production years 2010–2015 meet Euro 5 standards; 2016–2023 models meet Euro 6 (VCA UK Type Approval #VCA/EMS/4120).
The Mitsubishi 4N13 is a 2,268 cc inline‑four turbo‑diesel engineered for compact SUVs and light commercial vehicles (2010–2023). It combines an aluminum block with cast-iron liners, DOHC valvetrain, and a 2,000-bar common-rail system to deliver smooth power delivery and strong low-end torque. Designed to meet Euro 5 and Euro 6 emissions standards, it integrates advanced after-treatment including DPF and SCR systems for regulatory compliance.

The DOHC common-rail design provides smooth power delivery and strong low-end torque but requires strict adherence to 15,000 km oil change intervals using ACEA C3 5W-30 oil to protect the high-pressure fuel pump and turbo bearings. Use of ultra-low sulfur diesel (EN 590) is mandatory to prevent injector and DPF clogging. Early models (2010–2015) lack SCR and rely on EGR/DPF only; post-2016 units require AdBlue refills every 12,000–20,000 km. The reinforced fuel pump coupling introduced in 2016 mitigates a known failure mode per TSB-ME-12-044. Extended idling or short-trip driving increases DPF regeneration frequency and soot accumulation.
Oil Specs: Requires ACEA C3 or Mitsubishi MTF-04 (5W-30) specification (Mitsubishi TSB-ME-12-044).
Emissions: Euro 5 certification applies to 2010–2015 models; Euro 6 applies to 2016–2023 (VCA Type Approval #VCA/EMS/4120).
Power Ratings: Measured under ISO 1585 standards. Power output varies by ECU calibration and market (Mitsubishi TIS Doc. ME-N13-01).

The Mitsubishi 4N13 was used across Mitsubishi's ASX, Outlander, and L200 platforms with transverse or longitudinal mounting depending on model. This engine was co-developed under the Renault–Nissan–Mitsubishi Alliance and shares architecture with the Renault R9M. Platform-specific adaptations include revised engine mounts in the Outlander PHEV (non-hybrid diesel variant) and modified exhaust manifolds in the L200 Barbarian. From 2016, Euro 6 variants added SCR/AdBlue systems, creating hardware and software interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the left-side block near the cylinder head flange (Mitsubishi TIS ME-N13-01). The 7th VIN digit indicates engine family ('3' for 4N13 series). Visual cues: aluminum block with black plastic valve cover, variable-geometry turbo, and AdBlue tank (Euro 6 models only). Critical differentiation from 4N14: 4N13 has 2,268 cc displacement (vs. 2,437 cc) and lower power output. ECU part number prefix 'MR592' confirms 4N13 application. Fuel pump coupling kits for engines before 06/2016 use older design and are prone to torsional failure per Mitsubishi TSB-ME-12-044.
The 4N13's primary reliability risk is high-pressure fuel pump drive coupling failure on pre‑2016 builds, with elevated incidence in high-mileage or thermally cycled vehicles. Mitsubishi internal durability reports from 2015 indicated a notable share of early ASX and Outlander units experienced rail pressure faults before 120,000 km, while UK DVSA records show DPF-related MOT failures are common in short-trip usage. Extended oil intervals and use of non-C3 oil increase pump wear, making oil quality and AdBlue maintenance critical.
