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 dev…
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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 4N13 is generally reliable with proper maintenance. Early models (2010–2015) had fuel pump coupling issues, but post-2016 revisions improved durability. Its chain-driven timing and aluminum block reduce major failure risks. Using correct ACEA C3 5W-30 oil and adhering to service intervals greatly enhances longevity, especially for DPF and AdBlue systems.
Top issues include high-pressure fuel pump coupling failure (pre-2016), DPF clogging from short-trip driving, AdBlue system faults in Euro 6 models, and VGT turbo sticking due to carbon. These are documented in Mitsubishi TSB-ME-12-044 and DVSA MOT data. Most are preventable with proper driving patterns and fluid maintenance.
The 4N13 powered the ASX (2010–2019), Outlander (2012–2021), and L200/Triton (2015–2023) in 2.2L diesel variants. It was also used by Renault in the Koleos (2016–2021) as the dCi 180. All applications are transverse or longitudinal depending on platform, with Euro 5 (2010–2015) and Euro 6 (2016–2023) variants.
Yes—moderately. ECU remaps yield +20–30 kW safely on stage 1, as the stock internals handle torque well. However, the high-pressure fuel pump and turbo are limiting factors. Supporting upgrades (intercooler, EGR delete with DPF retention) are common, but AdBlue and DPF systems complicate tuning in Euro 6 markets.
Efficient for its class. In an Outlander 2.2 DI-D, expect ~6.5 L/100km (city) and ~4.8 L/100km (highway), or ~52 mpg UK combined. Real-world mixed driving typically returns 45–50 mpg (UK), depending on condition and driving style. Short trips significantly reduce economy due to DPF regeneration cycles.
Yes. The 4N13 is an interference engine. If the timing chain were to fail (extremely rare due to robust design), piston-to-valve contact would cause severe internal damage. However, the chain is maintenance-free and designed to last the engine’s lifetime under normal conditions.
Mitsubishi specifies 5W-30 synthetic oil meeting ACEA C3 or Mitsubishi MTF-04 standards. Always use low-SAPS oil designed for DPF systems. Change every 15,000 km or 12 months to prevent fuel pump wear and ensure after-treatment compatibility.
