Hyundai unveils a brand new 2,0L and 2,2L R-diesel engine
[align=justify:b3bd820d9b]
At the 8th Advanced Diesel Engine Technology Symposium held in South Korea, Hyundai introduced its brand new R-diesel powerplant. Details on the R-engine reveal that this is one of the technically most advanced and competitive engines Hyundai has ever developed.
Available in two displacements (2L and 2,2), the all-aluminum R-engine packs an impressive amount of horsepower and torque. With outputs of 184 horsepower for the 2,0L and 200hp for 2,2L units the engine offers more power and torque than any other diesel engine in its class. According to Hyundai, it is surpassing all German and French competitors.
Developed at the cost of 250 million won, the R-engine is equipped with the third generation common rail system and packs piezo-electric injectors that deliver fuel at 1800-bar for an unprecedented degree of accuracy and control.
To achieve Euro-5 emission compliancy, the R-engine is fitted with a close-coupled diesel particulate filter and highly efficient exhaust gas recirculation with by-pass valve.
Entering production in 2009, the all-new R-engine be first installed into the new 2010 Tucson and Sonata YF models. Both will be officially unveiled late next year. In the same year, the R-engine will also be applied to several Kia models, including next generation Kia Optima/Magentis and Sportage crossover.
Official press release:
On the occasion of the 8th Advanced Diesel Engine Technology Symposium held at the company’s Namyang R&D Center, Hyundai Motor Co. today unveiled details of its newest passenger diesel powerplant, the R-Engine . With an output of 184ps and 40kg of torque, the R-Engine is ahead of the rest of the class, surpassing all German and French competitors (200ps and 44.5kg-m for the 2.2-liter).
“R proves Hyundai’s diesel development capabilities really are world-class. With diesels becoming cleaner and more fuel efficient all the time, there’s a growing demand for diesel powerplants worldwide and Hyundai is well positioned to supply the market with the very best diesel technology,” said Dr. Hyun-Soon Lee, president of the Corporate Research and Development Division.
The R-Engine benefits from the third generation common rail system developed by Bosch whose piezo-electric injectors deliver fuel at 1800-bar for an unprecedented degree of accuracy and control. It also features an electronic variable geometry turbochargerand an advanced engine control unit (air system-based charge control).
Developed by a 150-man team at an investment cost of 250 billion won, the R-Engine harnesses Hyundai’s newest and most advanced development tools. Computional flow dynamics, structural and thermal analysis were used to optimize its design while computerized simulation of the die casting process was employed to achieve the optimal balance of strength and low weight.
Over 500 prototype engines were built during the 42 month-long development period which encompassed a wide variety performance and emissions tests, endurance as well as NVH, cooling and lubrication studies. Finally, the engine was installed in vehicles and subjected to exhaustive testing under all imaginable environmental conditions.
Available in 2- and 2.2-liter displacements, the all-aluminum 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 booming 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
The R-Engine will enter production next year and will see its first application on the 2010 Tuscon and Sonata models which are due to be launched in the coming year.
The R-Engine brings Hyundai’s diesel engine family fully up-to-date as it joins the U-Engine (1.1-liter, 1.4-liter and 1.6-liter), the A-Engine (2.5-liter) and S-Engine (3.0-liter V-6). [Source: Hyundai][/align:b3bd820d9b]
