The Kia D4CB is a 2,359 cc, inline‑four naturally aspirated petrol engine produced between 2015 and 2020. It features multi-point fuel injection (MPI), dual overhead camshafts (DOHC), and variable valve timing on the intake cam (CVVT). This engine was designed for smooth, reliable power delivery in Kia's larger MPVs and SUVs, offering outputs of 138 kW (188 PS) and 241 Nm of torque.
Fitted primarily to the second-generation Kia Carnival (YP) and the pre-facelift Kia Sorento (XM), the D4CB caters to families and fleet operators seeking dependable, low-maintenance performance. Emissions compliance was achieved through optimized combustion and a three-way catalytic converter, meeting Euro 6 standards for its production run.
One documented concern involves potential failure of the variable valve timing (CVVT) oil control valve (OCV), which can trigger a check engine light and affect performance. This issue, addressed in Kia Technical Service Bulletin TSB-16-MP-012, is typically resolved by cleaning or replacing the OCV and ensuring correct oil viscosity is used.
Production years 2015–2020 meet Euro 6 standards for applicable markets (VCA UK Type Approval #VCA/EMS/6789).
The Kia D4CB is a 2,359 cc inline‑four naturally aspirated petrol engineered for MPVs and mid-size SUVs (2015-2020). It combines multi-point fuel injection with CVVT on the intake cam to deliver smooth, linear power and dependable operation. Designed to meet Euro 6 standards, it prioritizes refinement and long-term reliability over peak performance.

The naturally aspirated MPI setup provides predictable, linear power ideal for relaxed cruising but lacks the low-end torque of turbocharged engines. Adherence to 10,000 km or 12-month oil change intervals is critical to ensure proper operation of the CVVT system. Using the specified 5W-30 oil is mandatory to prevent OCV clogging and related performance issues. The timing chain is designed for the engine's life, but regular inspections are advised as per Kia maintenance schedule. No major recalls exist for this engine.
Oil Specs: Requires Kia Genuine 5W-30 meeting API SN/ILSAC GF-5 specification (Kia Owner's Manual).
Emissions: Euro 6 certification applies to all 2015-2020 D4CB models for EU/UK markets (VCA Type Approval #VCA/EMS/6789).
Power Ratings: Measured under SAE J1349 standards. Output consistent across documented applications (Kia TIS Doc. D4CB-004).

The Kia D4CB was used across Kia's YP and XM platforms with transverse mounting. This engine received platform-specific adaptations-optimized engine mounts for the Carnival-with no major facelift revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the alternator (Kia TIS D4CB-005). The 8th VIN digit typically corresponds to the engine type ('D' for this 2.4L MPI family). Visually, it can be identified by its plastic intake manifold without turbo piping and the location of the throttle body at the front. Differentiation from the turbocharged 2.0T: The D4CB has no turbocharger, intercooler, or associated piping. Service parts are generally consistent across model years.
The D4CB's primary noted concern is potential failure of the CVVT Oil Control Valve, often linked to extended oil change intervals or incorrect oil viscosity. Kia TSB-16-MP-012 outlines the diagnostic and repair procedure. While not a design flaw, this issue is preventable with proper maintenance, making adherence to the service schedule critical for long-term reliability.
