BorgWarner of Auburn Hills, MI has produced a regulated
two-stage and variable turbine geometry (VTG) turbocharging technology for BMW's
3.0-liter straight six-cylinder diesel engine. The turbocharging technology was
designed to boost performance while improving fuel economy by 4 percent.
BorgWarner worked with BMW to unite two advanced
technologies in an effort to accelerate the carmaker's engine downsizing
strategy without compromising power and torque. The turbocharging system consists
of two series-connected turbochargers. A smaller turbocharger engages at low
engine speeds. As the engine reaches mid-range speeds, a larger, low-pressure
turbocharger takes over, providing the boost pressure to reach maximum engine
torque. The combination was designed to achieve both high torque at very low
revs and maximum output at high engine speeds.
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
