Hyundai R engine

The Hyundai R engine is a diesel 4-cylinder automobile engine produced by Hyundai Kia Automotive Group.

The 2.0L R-Engine is a 4-cylinder compacted graphited iron block and aluminum cylinder head unit, with chain driven dual overhead camshafts operating 4-valves per cylinder. Fuel is supplied to the unit using Bosch 3rd-generation common rail direct injection (CRDi) through piezo-electronic injectors operating at 1800 bar, with air being fed through an electronically managed variable geometry turbocharger and an advanced engine control unit (air system-based charge control).

Bore and Stroke are 84.0 mm (3.3 in) x 90.0 mm (3.5 in) for a total displacement of 1995 cc. It generates 136 kW (185 PS; 182 hp) of power and 400 N·m (295 lb·ft) of torque.

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 intake manifold and plastic oil filter housing.

To achieve Euro 5 emission compliancy, the R is fitted with a close-coupled Diesel particulate filter plus highly efficient exhaust gas recirculation with by-pass valve.

It is fitted to the 2009 Hyundai Tucson (2nd-Generation/Tucson ix in Korean Market) and 2010 Kia Sportage (3rd-Generation/Sportage R in Korean Market).

The 2.2L R-Engine is a 4-cylinder compacted graphited iron block and aluminum cylinder head, with chain driven dual overhead camshafts operating 4-valves per cylinder. Fuel is supplied to the unit using Bosch 3rd-generation common rail direct injection (CRDi) through piezo-electronic injectors operating at 1800 bar, with air being fed through an electronically managed variable geometry turbocharger and an advanced engine control unit (air system-based charge control).

Bore and Stroke are 85.4 mm (3.4 in) x 96.0 mm (3.8 in) for a total displacement of 2199 cc.

It generates 147 kW (200 PS; 197 hp) of power and 440 N·m (325 lb·ft) of torque.

As with the 2.0L version, 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 intake manifold and plastic oil filter housing.

To achieve Euro 5 emission compliancy, the R is fitted with a close-coupled Diesel particulate filter plus highly efficient exhaust gas recirculation with by-pass valve.
