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.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
