Hyundai has unveiled details of its newest diesel powerplant, the R-Engine.

Hyundai said the Euro-5 compliant four-cylinder engine in 2.0-litre form produces 184bhp and in 2.2-litre produces 199bhp, so beating power output of comparable engines from French and German manufacturers.

It will enter production next year for introduction in Hyundai's new SUV vehicles and large saloons.

The R-Engine benefits from the third generation common rail system with piezo-electric injectors to deliver fuel at 1800-bar for greater accuracy and control.

Reduced vibration

It also features an electronic variable geometry turbocharger and an advanced engine control unit.

The all-aluminium R-Engine is fitted with a 16-valve dual overhead camshaft which is driven by an internal steel silent timing chain.

For reduced vibration and lower noise, the R gets a lower balance shaft which has been encased in a stiffened ladder frame housing for increased rigidity.

Weight saving features include 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.
