The surge toward smaller, turbocharged automotive engines continues. Now comes word that a powerful four-cylinder engine from BMW with direct injection and turbocharger (designated X1 28i), has more torque than its six-cylinder predecessor; goes from 0 to 100 km per hour faster; and has a higher maximum speed.
One of the reasons is a Low-Emission Sealing Solutions (LESS) from Freudenburg, an automotive supplier specializing in materials technology. Friction is reduced at the crankshaft while at the same time increasing running performance.
Encoder technology, using precise magnetization technology, controls the combustion process in the engine. Freudenberg is using dynamic magnetization, which is used in encoders to give electricity impulses a magnetic pattern. This procedure allows for very accurate and highly variable signal transmission. This allows the signal from the encoder to be adapted exactly to meet the requirements of the sensor.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
A fun and informative tour you can attend at the upcoming Design & Manufacturing Minneapolis, MD&M Minneapolis, and other events there, is the Materials Innovation Tour on Wednesday afternoon. I'll be leading it.
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.
