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 smoo…

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 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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the N22B4 is generally a very reliable engine. Its main documented issue is the VTC actuator rattle, which is a relatively simple and inexpensive fix. With regular oil changes using the correct 0W-20 specification and avoiding excessive short-trip driving, these engines can easily exceed 200,000 km without major issues.
The most common issues are VTC actuator rattle on cold start, oil dilution from frequent short trips, engine mount failure, and PCV valve clogging. These are well-documented in Honda service bulletins like A14-058 and are generally straightforward to resolve.
The N22B4 was primarily used in the fourth-generation Honda CR-V (RE, 2013-2017) and the ninth-generation Honda Accord (CU, 2013-2015) in various international markets. It was typically badged as the 2.2 i-VTEC.
The N22B4 has limited tuning potential due to its naturally aspirated SOHC design. Minor gains can be achieved through intake and exhaust modifications, but substantial power increases are not practical. It is best appreciated for its smooth, torquey delivery and reliability.
The N22B4 offers good fuel economy for its size. In the CR-V, expect 35-42 mpg (UK) combined. In the lighter Accord, figures are slightly better, around 38-45 mpg (UK) combined. Real-world economy is commendable for a 2.2L engine, especially on highway journeys.
Yes. The N22B4 is an interference engine. If the timing chain were to fail (an extremely rare event), the pistons would collide with the open valves, causing catastrophic internal engine damage. The chain is designed to last the life of the engine with proper maintenance.
Honda strongly recommends 0W-20 synthetic oil for optimal performance, fuel economy, and protection of the VTC system. 5W-30 is an acceptable alternative in some regions, but 0W-20 is preferred for its cold-start flow characteristics.
