Hyundai R engine

The Hyundai R engine is a four-cylinder diesel automobile engine produced by Hyundai Motor Group. It was announced at the Advanced Diesel Engine Technology Symposium in November 2008 and began production in 2009. It has a compacted graphite iron block and an aluminium cylinder head with chain-driven double overhead camshafts and four valves per cylinder, a third-generation Bosch common rail with piezoelectric injectors at 1,800 bar, and a variable geometry turbocharger. A balancer shaft in a stiffened ladder frame reduces vibration, and a particulate filter and exhaust gas recirculation allow Euro 5 compliance. The 2.0-litre D4HA and 2.2-litre D4HB were fitted to the Santa Fe, Tucson, Grandeur and Palisade and to Kia models such as the Sorento and Sportage.
