The Honda R20K is a 1,997 cc, inline‑four naturally aspirated petrol engine produced between 2011 and 2015. It features port fuel injection, single overhead camshafts (SOHC), and i-VTEC variable valve timing. In standard applications, it delivers 112 kW (152 PS) and 190 Nm of torque, with i-VTEC enabling a broad, efficient power band for relaxed cruising.
Fitted primarily to the ninth-generation Honda CR-V (RE/RM) for certain global markets, the R20K was engineered for fuel efficiency, low emissions, and smooth daily driving. Emissions compliance was achieved through precise fuel metering and a close-coupled catalytic converter, meeting Euro 5 standards from launch.
One documented service consideration is potential for timing chain tensioner wear, noted in Honda Service Bulletin A13-018. This can manifest as a brief rattle on cold startup and is typically addressed under warranty or via a revised tensioner part in later production runs.

Production years 2011–2015 meet Euro 5 standards across all applicable markets (EU Regulation (EC) No 715/2007).
The Honda R20K is a 1,997 cc inline‑four naturally aspirated petrol engineered for compact SUVs (2011-2015). It combines port fuel injection with SOHC i-VTEC to deliver smooth, predictable power and excellent fuel economy. Designed to meet Euro 5 standards, it prioritizes efficiency and low running costs.

The SOHC i-VTEC design offers smooth, linear power ideal for commuting and light towing but lacks the high-RPM excitement of DOHC engines. The port injection system is inherently resistant to intake valve carbon buildup. Using the specified 5W-20 oil ensures optimal fuel economy and chain longevity. The engine's size can make certain repairs, like rear bank spark plugs, more labor-intensive. Cold-start rattle should be investigated per Honda SIB A13-018.
Oil Specs: Requires Honda 5W-20 specification for optimal fuel economy (Honda Owner's Manual). 5W-30 is an acceptable alternative.
Emissions: Euro 5 certification applies to all 2011–2015 models (EU Regulation (EC) No 715/2007). No market-specific variations.
Power Ratings: Measured under SAE J1349 standards. Peak output requires 95 RON fuel (Honda TIS Doc. R20K-PERF).

The Honda R20K was used across Honda's RE/RM platform with transverse mounting and was exclusive to Honda. This engine received platform-specific adaptations-reinforced engine mounts for the CR-V for higher NVH standards-and all variants share the same core architecture. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the engine block, near the alternator (Honda TIS R20K-ID). The 8th VIN digit for R20K-equipped vehicles is typically 'R'. The engine can be visually identified by its silver plastic valve cover with "i-VTEC" branding and the absence of a turbocharger. Critical differentiation from the K24: The R20K has a SOHC design and 2.0L displacement (vs. 2.4L). Service parts, including the timing chain tensioner, were revised in 2013; pre-2013 parts may not be compatible with later engines (Honda SIB A13-018).
The R20K's primary reliability consideration is timing chain tensioner wear, with elevated incidence in high-mileage or infrequently serviced vehicles. Honda service data indicates this is a common wear item rather than a systemic failure, while owner reports frequently cite minor oil consumption in engines with over 150,000 km. Consistent use of correct oil and adherence to service intervals mitigates most long-term concerns.
