BorgWarner Turbo Technology gives CNG-Powered cars a boost

Announcement of BorgWarner's plans to supply turbochargers for the Opel 1.6-liter compressed natural gas engine and the VW 1.4-liter TSI EcoFuel engine, the world's first direct-injection turbocharged engine modified for CNG operation.

BorgWarner will supply turbochargers for the Opel 1.6-liter compressed natural gas (CNG) engine and the VW 1.4-liter TSI EcoFuel engine.

CNG engines produce about 70 percent less nitrous oxide than diesel engines and about 25 percent less carbon dioxide than gasoline engines, but are slower to accelerate than the fossil fuel counterparts.

To lower weight and guarantee a fast response on the Opel Zafira ecoFlex Turbo, BorgWarner worked with Opel to optimize the water-cooled turbocharger. The engine delivers powerful performance, accelerating from 0 to 62 mph (100 km/hr) in 11.5 seconds.

BorgWarner also worked with Volkswagen on the VW Passat TSI EcoFuel to optimize air delivery and boost pressure for a CNG engine. The turbocharger enables the CNG engine to develop and maintain a torque of 220 Nm, up to an engine speed of 4,800rpm.
