Kirchheimbolanden, 14 July 2006 – BorgWarner Turbo Systems confirms again its position as a leading supplier of turbocharger technology for spark-ignition engines. The automotive-supplier has developed a new K04 Twin-Scroll turbocharger which will be used for the first time in a spark-ignition engine with direct fuel injection and turbocharging. The engine will be launched soon onto the US market. In this market, BorgWarner sees a high potential for vehicles that need powerful, yet fuel- and space-efficient engines. The carefully matched turbocharger ensures immediate engine response while providing excellent fuel economy and low emissions within an extremely compact design. At 194 kW (260 bhp) and 353 Nm (260 lb.-ft) the 2.0-l Turbo engine provides approximately the same performance as larger V6 units but with better fuel economy.
High Power – Low Fuel Consumption
The K04 Twin-Scroll turbocharger from BorgWarner Turbo Systems also features an integrated blow-off valve and a high efficiency turbine wheel. The Twin-Scroll turbine design further ensures that exhaust pressure pulses are effectively utilized at low engine speeds, thus optimizing the ratio between charging pressure and backpressure. The boost effect from the Twin-Scroll turbocharger is evident as low as 1400 rpm and ensures optimum response even at low engine speeds.
