BorgWarner to equip Renault diesel engine with VTG turbochargers

Patrick Keane Published 25 January 2012

BorgWarner said that its latest generation of variable turbine geometry (VTG) turbochargers are being supplied for the new 1.6-litre Energy dci 130 diesel engine built by French carmaker Renault.

The company said that its new VTG turbocharger will help the engine set high standards of efficiency with reduced CO2 emissions of 115 g/km (185 grams/mile) and 20% percent better fuel economy compared with its 1.9-liter predecessor.

The new four-cylinder diesel engine which will generate 130 HP and 320 Nm (236 lb.-ft.) of torque at 1,750 rpm, is intended for Renault's and Nissan's European mid-range C-segment vehicles.

BorgWarner president and GM of turbo systems passenger car products Frederic Lissalde said the company's advanced turbocharging technology combined with its exhaust gas recirculation (EGR) cooler and tube on the low pressure EGR system allows drivers to experience the benefits of significantly improved fuel economy and reduced emissions without sacrificing performance.

"We value our long-standing and successful partnership with Renault and are pleased to provide them our latest engine technologies," Lissalde said.

To develop the new generation of its BV38 VTG turbocharger, the company has replaced the straight turbine vanes with a patented S-shaped vane to improve thermodynamics, response and controllability.
