The Honda N22B2 is a 2,199 cc, inline‑four naturally aspirated petrol engine produced between 2012 and 2015. It features port fuel injection, dual overhead camshafts (DOHC), and i-VTEC variable valve timing. This engine delivers 110 kW (150 PS) and 202 Nm of torque, with i-VTEC enabling a broad, efficient powerband for smooth urban and highway driving.
Fitted primarily to the ninth-generation Accord (CU) and the second-generation CR-V (RM) across select global markets, the N22B2 was engineered for refined cruising, low emissions, and dependable performance. Emissions compliance was achieved through optimized combustion and a close-coupled catalytic converter, allowing it to meet stringent Euro 5 standards.
One documented concern is premature failure of the VTC (Variable Timing Control) actuator solenoid, which can cause rough idling and trigger diagnostic trouble codes. This issue, referenced in Honda Service Bulletin 13-045, is often linked to oil contamination or infrequent oil changes. Honda addressed this with revised solenoid assemblies for affected model years.

All production years (2012–2015) meet Euro 5 standards (VCA UK Type Approval #VCA/HON/3456).
The Honda N22B2 is a 2,199 cc inline‑four naturally aspirated petrol engineered for mid-size sedans and SUVs (2012-2015). It combines port fuel injection with i-VTEC variable valve timing to deliver smooth, linear power and strong low-to-mid range torque. Designed to meet Euro 5 emissions standards, it balances refinement with everyday drivability.

The i-VTEC system provides smooth, linear power delivery ideal for highway cruising but demands regular oil changes with Honda 5W-30 specification to ensure proper VTC solenoid function. Extended oil change intervals or poor-quality oil can lead to VTC solenoid failure, causing rough idle and potential engine codes per Honda SIB 13-045. The engine is known for its fuel efficiency under normal driving conditions.
Oil Specs: Requires Honda 5W-30 specification (Honda SM N22B2-SM). ACEA A5/B5 or equivalent is acceptable.
Emissions: Euro 5 certification applies to all models (VCA Type Approval #VCA/HON/3456).
Power Ratings: Measured under SAE J1349 standards. Peak output requires 95 RON fuel (Honda TSB 13-045).

The Honda N22B2 was used exclusively in Honda's CU/RM platforms with transverse mounting. This engine received no major platform-specific adaptations, but software calibrations varied slightly between the Accord and CR-V applications. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the alternator (Honda SM N22B2-SM). The 8th VIN digit for Accord is typically 'C'; for CR-V, it varies by market. Visually, the N22B2 is identifiable by its black plastic valve cover and the "2.2 i-VTEC" badge on the engine cover. Critical differentiation from the K24 series: N22B2 is a 2.2L i-VTEC with a chain-driven timing system, while K24 engines are 2.4L with different bore/stroke dimensions. Software and some sensors are interchangeable between Accord and CR-V applications.
The N22B2's primary reliability risk is VTC solenoid failure, with elevated incidence in vehicles subjected to infrequent oil changes. Honda service data indicates a notable failure rate before 120,000 km in affected batches, while owner reports frequently cite issues after extended service intervals. Poor oil quality or infrequent changes increases solenoid wear, making adherence to the maintenance schedule critical.
