1. Product Overview
The D4HA and D4HB are part of Hyundai’s R-engine series, representing 2.0L inline-4 common rail turbo diesel engines. These engines are widely used in SUVs, sedans, and vans such as the Tucson, Santa Fe, Sportage, i40, Sorento, and more.
The cylinder head is made from lightweight aluminum alloy, features 16 valves with dual overhead camshafts (DOHC), and is compatible with high-pressure common rail injection systems.
D4HA and D4HB share similar architecture, with minor differences in tuning, emissions setup, and turbocharger specs. The cylinder head itself is often interchangeable.
