New BorgWarner Turbine Geometry Improves Power, Cuts Emissions

Redesigned cast iron turbochargers will debut in VW’s 55-kW diesel engines Optimizes engines' power output Better engine response, efficiency Euro 6 compliance

Auto parts manufacturer BorgWarner introduced an "advanced variable turbine geometry" (VTG) turbocharger for Volksawagen’s new 1.4-liter three-cylinder diesel engines. Manufactured from complex ferrous castings to improve fuel economy and reduce emissions, BorgWarner reported its VTG turbochargers would boost the performance standards for VW’s 55-kW (75 PS) and 66-kW (90 PS) diesel engines.

The turbochargers are manufactured at a BorgWarner complex in Bielsko-Biala, Poland, completed in 2009.

BorgWarner's said its VTG turbocharging technology precisely adjusts the relevant engine operating points to optimize power output. To improve thermodynamics and engine response at very low rpm, patented S-shaped guide vanes regulate VTG turbine output by changing the inflow angle and speed at the turbine wheel inlet.

It added that the new turbocharger “significantly improves engine response and increases efficiency in the low rev band, resulting in increased combustion efficiency and reduced emissions.”

Both engines have been developed to comply with Euro 6 emissions standards, and to improve the engines’ fuel economy up to 21% compared with the predecessor models. The Euro 6 standards were implemented in September 2014 for passenger and commercial vehicles, and intensify the restrictions on emissions of CO, hydrocarbons, non-methane hydrocarbons, NOx, hydrocarbons + NOx, and particulates.

The new 55-kW diesel engine will make its debut in the VW Polo, a five-seat “super-mini” vehicle that achieves an average fuel consumption up to 75 mpg (3.1 liters/100 km). The new engines also will be available for other vehicles the group develops for the Audi, Seat, Škoda and VW nameplates.

"We value our successful and long-standing partnership with the Volkswagen Group," stated BorgWarner Turbo Systems president and general manager Frédéric Lissalde, President and General Manager, BorgWarner Turbo Systems. "BorgWarner is pleased to provide its latest turbocharging technology for Volkswagen's modern diesel engines to achieve optimum power output with improved fuel economy."
