The Honda F22A4 is a 2,156 cc, inline‑four petrol engine produced between 1993 and 1997. It features a single overhead camshaft (SOHC) with 16 valves and Honda's PGM-FI (Programmed Fuel Injection) system. This design prioritized low-end torque and smooth, reliable power delivery for larger Honda sedans, producing 98 kW (133 PS) and 192 Nm of torque.
Fitted primarily to the fourth-generation Honda Accord (CD) for the North American market, the F22A4 was engineered for comfortable, refined cruising and dependable daily transportation. Emissions compliance for its production period was met through electronic fuel injection and a catalytic converter, allowing it to meet US EPA Tier 0 standards.
One documented engineering characteristic is its use of a balance shaft to reduce vibration, detailed in Honda Service Bulletin 93-028. This feature enhanced refinement in the larger Accord platform, distinguishing it from the higher-performance F22A1 variant which lacked this component.

Production years 1993–1997 meet applicable US EPA Tier 0 emissions standards for passenger vehicles of that era (Honda Internal Emissions Certification Docs).
The Honda F22A4 is a 2,156 cc inline‑four naturally aspirated petrol engine engineered for mid-size sedans (1993-1997). It combines SOHC 16-valve architecture with PGM-FI fuel injection and a balance shaft to deliver smooth, linear power and refined cruising. Designed to meet early-1990s US emissions standards, it prioritizes drivability and mechanical simplicity.

The balance shaft provides exceptional smoothness for a large four-cylinder engine but adds complexity. Strict adherence to 90,000 km timing belt replacement intervals is critical to prevent catastrophic failure. The PGM-FI system requires clean fuel filters and properly functioning sensors for optimal performance. The distributor-based ignition system should be inspected for wear. Regular oil changes with the correct viscosity protect the valvetrain and balance shaft bearings.
Oil Specs: Requires 10W-30 meeting API SH specification (Honda Owner's Manual 1994 Accord).
Emissions: Certification applies to 1993-1997 models for the North American market (Honda Internal Emissions Certification Docs).
Power Ratings: Measured under SAE J1349 standards (Honda Group PT-1995).

The Honda F22A4 was used across Honda's CD platform with transverse mounting. This engine received minor ECU and accessory bracket variations between model years, creating minor part number differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the engine block, near the timing belt cover (Honda Workshop Manual 1994 Accord). Visually, it can be identified by its SOHC valve cover and the presence of a balance shaft housing at the bottom of the engine block. Critical differentiation from the F22A1: The F22A4 has a lower compression ratio (8.8:1 vs 9.8:1), less aggressive cam profiles, and includes a balance shaft for refinement. The distributor is mounted at the rear of the cylinder head.
The F22A4 is renowned for its durability, with the primary long-term concern being timing belt failure if replacement intervals are neglected. Honda service data indicates that failure to replace the belt at 90,000 km can lead to catastrophic engine damage due to its interference design. The distributor and balance shaft seals are also common wear items after 150,000 km.
