The Peugeot CFB (1KR) is a 998 cc, inline‑three naturally aspirated petrol engine produced between 2012 and 2021. It features a lightweight aluminium block, dual overhead camshafts (DOHC), and a chain-driven valvetrain. This engine was calibrated to deliver 50 kW (68 PS) and 93 Nm of torque, with its compact design prioritizing low weight and fuel efficiency for urban mobility.
Fitted exclusively to the Peugeot 108, the CFB (1KR) was engineered for agile, economical city driving. Emissions compliance for its entire production run was achieved through a three-way catalytic converter and precise electronic fuel injection, meeting the stringent Euro 5 and later Euro 6 standards.
One documented reliability concern involves potential failures of the ignition coil packs, which can lead to misfires and rough running. This issue, referenced in Peugeot Service Bulletin 14BZ09D, is often linked to heat cycling and electrical stress. Later production batches incorporated revised coil units to improve durability.
Production years 2012–2015 meet Euro 5 standards; 2016–2021 models meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/7890).
The Peugeot CFB (1KR) is a 998 cc inline‑three naturally aspirated petrol engine engineered for city cars (2012-2021). It combines a lightweight aluminium block with DOHC architecture to deliver responsive, economical performance. Designed to meet Euro 5 and Euro 6 standards, it prioritizes low emissions and urban efficiency.

The naturally aspirated design provides linear, predictable power delivery ideal for city driving but requires strict adherence to 20,000 km or 12-month oil change intervals to protect the timing chain. Using PSA B71 2030 (5W-30) oil is critical for optimal engine protection and emissions system compatibility. The Denso ignition system is susceptible to heat stress; Service Bulletin 14BZ09D details the revised coil pack replacement procedure for affected units. Regular spark plug replacement is recommended to maintain efficiency.
Oil Specs: Requires PSA B71 2030 (5W-30) specification (Peugeot Owner's Manual). Compatible with ACEA A5/B5.
Emissions: Euro 5 certification applies to 2012-2015 models; Euro 6 for 2016-2021 (VCA Type Approval #VCA/EMS/7890).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model range (Peugeot TIS Doc. B75500).

The Peugeot CFB (1KR) was used exclusively in the Peugeot 108 (B9) platform with transverse mounting. This engine is a licensed version of the Suzuki 1KR-FE, manufactured under agreement for the PSA-Toyota-Suzuki collaboration on the A-segment platform. No major hardware revisions affected core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat surface of the cylinder block, near the gearbox flange (Peugeot TIS B74950). The engine code 'CFB' or '1KR' will be clearly visible. The 8th digit of the VIN is typically 'A' for this variant. Visually, it can be identified by its compact size, black plastic valve cover, and the location of the ignition coils on top of each spark plug. Critical differentiation from other PSA 1.0L engines: The CFB features a specific Denso ECU (e.g., MED17.5.5) with a unique connector. Ignition coil part numbers must be verified against the engine serial number for compatibility (Peugeot SIB 14BZ09D).
The CFB (1KR)'s primary reliability risk is ignition coil pack failure, with elevated incidence in vehicles subjected to frequent short trips and hot climates. Peugeot internal reports noted a cluster of misfire complaints requiring coil replacement before 80,000 km, while UK DVSA data indicates no major systemic failures beyond this. Adherence to spark plug replacement intervals is critical to reduce coil stress.
Analysis derived from Peugeot technical bulletins (2012-2021) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
