Hyundai R engine

The Hyundai R engine is a diesel <a href="/facts/Inline-four_engine/NVgxSDFb">4-cylinder</a> <a href="/facts/Automobile_engine/BuaC19cV">automobile engine</a> produced by <a href="/facts/Hyundai_Motor_Group/hkXwBsAF">Hyundai Motor Group</a>, it was announced during the Advanced Diesel Engine Technology Symposium in November 2008 and began production in 2009.
The R line of engines feature four cylinders compacted graphite iron block and aluminum cylinder head unit, with chain driven dual overhead camshafts operating four valves per cylinder. Fuel is supplied to the unit using <a href="/facts/Robert_Bosch_GmbH/wPuk1Udv">Bosch</a> 3rd-generation <a href="/facts/Common_rail/kPT9eP0J">common rail direct injection</a> (CRDi) through <a href="/facts/Piezoelectric_motor/ceNw2FJm">piezoelectric</a> Bosch injectors operating at 1,800 <a href="/facts/Bar_(unit)/wwFWTTkT">bar</a> (26,000 <a href="/facts/Pound_per_square_inch/RMdeTlB0">psi</a>), with air being fed through an electronically managed variable geometry turbocharger and an advanced engine control unit (air system-based charge control).
For reduced vibration and lower booming noise, the R gets a lower balancer shaft which is encased in a stiffened ladder frame housing for increased rigidity. Weight saving features include a serpentine belt with isolation pulley, a plastic head cover, plastic <a href="/facts/Intake_manifold/VDPnE747">intake manifold</a> and plastic oil filter housing.
To achieve <a href="/facts/Euro_5/uPnvP1BL">Euro 5</a> emission compliancy, the R is fitted with a close-coupled Diesel particulate filter plus highly efficient <a href="/facts/Exhaust_gas_recirculation/W1T5eJbU">exhaust gas recirculation</a> with by-pass valve.
