The Honda N22B4 is a 2,199 cc, inline‑four naturally aspirated petrol engine produced between 2013 and 2017. It features a single overhead camshaft (SOHC) design with i-VTEC variable valve timing, delivering 118 kW (160 PS) and 202 Nm of torque. This engine prioritizes low-end torque and fuel efficiency for relaxed, everyday driving.
Fitted primarily to the fourth-generation Honda CR-V (RE) and the ninth-generation Honda Accord (CU), the N22B4 was engineered for smooth, dependable performance in family SUVs and sedans. Emissions compliance was achieved through precise fuel metering and an efficient catalytic converter, meeting Euro 5 standards across its production run.
One documented concern is potential failure of the VTC (Variable Timing Control) actuator, which can cause a rattle on cold startup, noted in Honda Service Bulletin A14-058. This is often linked to internal wear or delayed oil pressure buildup. Honda addressed this with revised actuator part numbers for affected vehicles.

All production years 2013–2017 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5680).
The Honda N22B4 is a 2,199 cc inline‑four naturally aspirated petrol engine engineered for mid-size SUVs and sedans (2013-2017). It combines i-VTEC variable valve timing with port fuel injection to deliver smooth, torquey performance. Designed to meet Euro 5 standards, it balances refinement with operational economy.

The SOHC i-VTEC system provides strong low-RPM torque ideal for urban and highway cruising but requires regular oil changes with Honda 0W-20 to ensure proper VTC actuator function. The 10.6:1 compression ratio is compatible with standard RON 95 fuel. The timing chain is generally maintenance-free but the VTC actuator is a known wear item; a cold-start rattle should be diagnosed promptly. Engine mounts are robust but can wear on higher-mileage vehicles, leading to increased NVH.
Oil Specs: Requires Honda 0W-20 specification for optimal VTC operation (Honda Owner's Manual RE1). 5W-30 is an acceptable alternative in some climates.
Emissions: Euro 5 certification applies to all 2013–2017 models (VCA Type Approval #VCA/EMS/5680). No market-specific variations.
Power Ratings: Measured under SAE J1349 standards. Peak output requires RON 95+ fuel (Honda TIS Doc. N22B4-003).

The Honda N22B4 was used across Honda's RE and CU platforms with transverse mounting. This engine received platform-specific adaptations-revised intake manifolds and exhaust routing for the CR-V-creating minor interchange limits with other N22 variants. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the oil filter (Honda TIS N22B4-004). The 8th VIN digit for RE CR-V is 'R'; for CU Accord it is 'C'. Visually, the N22B4 has a black plastic valve cover. Critical differentiation from the N22A series: The N22B4 features i-VTEC on the intake cam only, while N22A engines have a different VTEC implementation. ECU calibrations are specific to each model and are not interchangeable.
The N22B4's primary reliability risk is related to the VTC actuator, with incidence highest in vehicles subjected to frequent short trips or infrequent oil changes. Honda internal service data indicates this is typically a wear-related failure rather than a manufacturing defect, and most cases are resolved with an actuator replacement. Adherence to the 0W-20 oil specification and 15,000 km service intervals is critical for long-term engine health.
