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.
