The VTG turbocharger S300V developed for International also offers the latest technology. One decisive feature required was the titanium compressor wheel to allow the higher horsepower engine ratings to achieve the performance goals. An additional key component necessary to provide the right level of control and response of the VTG turbocharger is the electronically controlled and driven actuation system. This system allows the engine control module to optimize the overall engine performance through the tightly monitored and controlled vane position. One of the greatest challenges in meeting customer wishes with regards to fuel consumption, emissions and performance was the efficiency of the turbocharger compressor stage. This required BorgWarner Turbo Systems’ development group to provide a customized design to meet International’s ambitious performance and efficiency goals.
