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.
Dow Chemical and several other companies have launched a program in Omaha, Neb. to divert about 36 tons of plastics from landfills in its first phase, and convert it into energy used for cement production.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
