BorgWarner Boosts Performance of Downsized Diesel Engines

AUBURN HILLS, Mich., Jan. 27, 2011 /PRNewswire/ -- BorgWarner now supplies the latest generation of variable turbine geometry (VTG) turbochargers for the newly developed 1.6-liter four-cylinder common-rail diesel engines featured in the new MINI family. The downsized engine is available with a power output of 90 HP (66 kW) in the MINI One D and One D Clubman and with 112 HP (82 kW) in the Cooper D and Cooper D Clubman – and for the first time in the Cooper Convertible. Controlled by an electric actuator, BorgWarner's BV35 VTG turbocharger helps the engine set new standards of efficiency and performance, achieving  average fuel consumption of 61.8 mpg (3.8 liters/100 km) in both hatchback models, with CO2 emissions as low as 99 g/km.

"Using BorgWarner's advancements in turbocharging technology, modern diesel engines achieve optimum power output and great fuel economy," said Roger Wood, Executive Vice President, BorgWarner. "We are pleased to extend our very successful and long-standing partnership with the BMW Group to the compact car segment."

With BorgWarner's next generation VTG turbocharger, it was possible to downsize the diesel engine's displacement from 2.0 liters to 1.6 liters while maintaining the optimum ratio between bore and stroke of the combustion chambers. To improve 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. Compared with diesel engines previously utilized in the MINI, the new four-cylinder units deliver higher maximum torque of 215 Nm and 270 Nm respectively, achieving greater pulling power for an exciting driving experience, while setting a new benchmark in lower fuel consumption.
