The Honda R20Z1 is a 1,997 cc, inline‑four naturally aspirated petrol engine produced between 2011 and 2015. It features i-VTEC variable valve timing, port fuel injection, and dual overhead camshafts (DOHC). In standard form it delivered 110 kW (150 PS) and 190 Nm of torque, engineered for refined, efficient performance in Honda's compact SUVs.
Fitted to the second-generation CR-V (RE), the R20Z1 was designed for smooth, linear power delivery and low running costs. Emissions compliance was met through a close-coupled catalytic converter and advanced engine management, allowing compliance with stringent Euro 5 standards across all markets.
One documented engineering focus was optimizing low-RPM torque for urban drivability. Honda addressed this through revised intake cam profiles and a higher compression ratio, as detailed in Service Bulletin SB‑11‑008. This update improved throttle response without compromising fuel economy.
All production years (2011–2015) meet Euro 5 emissions standards globally (EU Regulation (EC) No 715/2007, Annex XIII).

The engine's linear power delivery is ideal for daily commuting but requires premium 95 RON fuel for optimal performance and to prevent knock. Honda 5W-30 oil is specified for its balance of protection and efficiency. The chain-driven system is robust and requires no scheduled replacement. The port injection system virtually eliminates intake valve carbon buildup, making this engine very low-maintenance. The i-VTEC system engages smoothly around 4,500 rpm for a noticeable power boost.
Oil Specs: Requires Honda 5W-30 specification meeting API SM/ILSAC GF-4 (Honda SIB SB-11-008).
Emissions: Euro 5 certification applies to all model years globally (EU Regulation (EC) No 715/2007, Annex XIII).
Power Ratings: Measured under SAE J1349 standards. Peak power requires 95 RON fuel (Honda TIS Doc. R20Z1-A26015).

The Honda R20Z1 was developed exclusively for Honda's second-generation CR-V (RE) platform with transverse mounting and is not licensed to other manufacturers. This engine received no major platform-specific adaptations. All applications are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the alternator (Honda TIS R20Z1-A24890). The 8th VIN digit for RE CR-V models with this engine is 'R'. Visually, the engine is identifiable by its silver plastic engine cover with 'i-VTEC' lettering. Critical differentiation from the K24Z7: The R20Z1 is a 2.0L with port injection, while the K24Z7 is a 2.4L with direct injection. Service parts are not interchangeable.
The R20Z1's primary reliability focus is maintaining the i-VTEC system. Honda's internal durability testing showed exceptional long-term reliability, with the chain-driven timing system being effectively maintenance-free. Owner data suggests the VTEC oil pressure switch is the most common failure point, often linked to infrequent oil changes.
Analysis derived from Honda technical bulletins (2011-2015) and aggregated European owner club failure statistics (2013-2020). Repair procedures should follow manufacturer guidelines.
