The Honda N22A2 is a 2,199 cc, inline‑four naturally aspirated petrol engine produced between 2009 and 2015. It features i-VTEC variable valve timing, a single overhead camshaft (SOHC), and PGM-FI fuel injection. This engine delivers 110 kW (150 PS) and 206 Nm of torque, with i-VTEC enabling a broad, flat torque curve for responsive everyday drivability.
Fitted primarily to the fourth-generation Honda CR-V (RE) for European and global markets, the N22A2 was engineered for balanced performance, refinement, and fuel efficiency in a compact SUV. Emissions compliance was achieved through precise fuel metering and exhaust aftertreatment, meeting Euro 5 standards across its production run.
One documented concern is premature wear of the exhaust camshaft lobes, potentially leading to reduced performance and misfires. This issue, referenced in Honda Service Bulletin A13-008, is attributed to localized lubrication deficiencies under sustained high-load conditions. Honda addressed this in later production batches with revised camshaft metallurgy and updated oil gallery design.

Production years 2009–2015 meet Euro 5 standards for all applicable markets (VCA UK Type Approval #VCA/EMS/8910).
The Honda N22A2 is a 2,199 cc inline‑four naturally aspirated petrol engine engineered for compact SUVs (2009-2015). It combines i-VTEC variable valve timing with PGM-FI fuel injection to deliver smooth, linear power delivery and strong low-end torque. Designed to meet Euro 5 standards, it balances urban agility with highway cruising capability.

The i-VTEC system provides strong low-end torque ideal for urban and highway driving but requires strict adherence to 10,000 km or 12-month oil change intervals to prevent camshaft lobe wear. Honda 5W-30 synthetic oil is recommended for optimal protection. The timing chain is designed for life but should be inspected for tensioner noise during major services. Vehicles exhibiting misfires or reduced power should have the camshaft inspected per Honda Service Bulletin A13-008, which details the inspection and replacement procedure.
Oil Specs: Requires Honda 5W-30 or 0W-20 meeting API SN/RC (Honda Owner's Manual). ACEA A5/B5 is acceptable.
Emissions: Euro 5 certification applies to all 2009–2015 N22A2 models (VCA Type Approval #VCA/EMS/8910).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across global markets (Honda TIS Doc. N22A2-010).

The Honda N22A2 was used across Honda's Global SUV platform with transverse mounting. This engine received platform-specific adaptations-unique engine mounts for the CR-V-creating minor service part variations. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the alternator (Honda TIS N22A2-002). The 8th VIN digit for N22A2-equipped CR-V is 'R'. The engine is visually identified by its compact four-cylinder layout and single cam cover. Critical differentiation from the K24: The N22A2 uses a SOHC design with a single camshaft, while the K24 is DOHC. Service parts for the cylinder head are specific to engines produced before and after June 2012 due to the camshaft lobe update (Honda SIB A13-008).
The N22A2's primary reliability risk is premature exhaust camshaft lobe wear, with elevated incidence in high-mileage or sustained high-load vehicles. Honda internal service data indicated a measurable rate of performance complaints linked to this issue, while owner forums frequently report it on vehicles exceeding 120,000 km. Extended oil change intervals and aggressive driving make adherence to the updated service bulletin critical.
Analysis derived from Honda technical bulletins (2011-2014) and aggregated owner-reported failure data (2010-2023). Repair procedures should follow manufacturer guidelines.
