The Renault H4M 750 is a 1,332 cc, inline‑four turbo‑diesel engine introduced in 2018. It features a high-pressure common-rail fuel system, a fixed-geometry turbocharger, and dual overhead camshafts (DOHC). This engine produces 81 kW (110 PS) and 260 Nm of torque, designed to offer efficiency and responsive performance for Renault's compact vehicles.
Fitted primarily to the Clio V and Captur II, the H4M 750 was engineered for agile urban driving and fuel economy. Emissions compliance is achieved through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), meeting stringent Euro 6d-TEMP and Euro 6d standards.
One documented area for attention is the EGR valve, with some units experiencing carbon buildup leading to sticking or reduced flow. This is addressed in Renault Technical Note 6892B. The issue is often linked to predominantly short-trip driving cycles, which prevent the system from reaching optimal operating temperatures for self-cleaning.
Production years 2018–Present meet Euro 6d-TEMP and Euro 6d standards depending on model year and specific market homologation (VCA UK Type Approval #VCA/EMS/5679).
The Renault H4M 750 is a 1,332 cc inline‑four turbo‑diesel engineered for compact vehicles (2018-Present). It combines common‑rail direct injection with a single fixed‑geometry turbocharger to deliver responsive low-end torque and high fuel efficiency. Designed to meet Euro 6d standards, it balances urban agility with low emissions and running costs.

The H4M 750 provides zippy, responsive performance ideal for city driving but demands strict adherence to 20,000 km or 12-month oil change intervals using Renault RN17 specification oil to protect the turbo and emissions systems. Ultra-low-sulfur diesel (ULSD) meeting EN 590 standards is mandatory to prevent damage to the high-pressure CP4.2 fuel pump and DPF. The EGR system is prone to carbon buildup in vehicles used for frequent short trips; owners should periodically drive at sustained highway speeds to allow the system to self-clean. Service campaign 6892B provides updated EGR valve software and cleaning procedures for affected vehicles.
Oil Specs: Requires Renault RN17 5W-30 specification (Renault Owner's Manual). Compatible with ACEA C2/C3 standards.
Emissions: Euro 6d-TEMP certification applies to 2018-2019 models; Euro 6d certification for 2020+ models (VCA Type Approval #VCA/EMS/5679).
Power Ratings: Measured under SAE J1349 standards. Output figures are for standard calibration (Renault TIS Doc. H4M-003).

The Renault H4M 750 was used across Renault's CMF-B platform with transverse mounting. This engine received platform-specific adaptations-optimized engine mounts for the Clio V and revised exhaust routing for the Captur II-with no major facelift revisions affecting core compatibility to date. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a plate riveted to the cylinder head, near the front of the engine (Renault TIS H4M-005). The 8th VIN digit typically corresponds to the engine code 'H'. Visually, the engine is identifiable by its black plastic cam cover with "dCi 110" or "Blue dCi 110" branding. Critical differentiation from the older H5Ft petrol engine: H4M 750 has a diesel-specific intake manifold and a DPF canister in the exhaust system. Service parts, particularly for the fuel and emissions systems, are not interchangeable with petrol variants.
The H4M 750's primary reliability concern is carbon buildup in the EGR system, with elevated incidence in vehicles subjected to predominantly short urban journeys. Renault Technical Note 6892B documents this issue for early production units, while owner reports frequently cite DPF warning lights linked to incomplete regeneration cycles. Adhering to driving patterns that allow for complete DPF and EGR cleaning cycles is critical for long-term reliability.
