WITH METROLOGY FROM MAHR MAHR. THE AUTOMOTIVE APPLICATION SPECIALIST Precision and driving dynamics belong together in the automobile. Driving dynamics is only possible with precision-engineered and precision-measured components. In order to keep it this way Mahr offers field-proven measurement technology that follows the major trends in the automotive industry. In the foreseeable future the internal combustion engine will remain the predominant type of drive. For this reason many efforts are being made to significantly reduce the consumption of the engine and to meet stringent CO2 emission regulations. An important element in the reduction of fuel consumption is downsizing. For example the number of cylinders can be reduced from 4 to 3 or from 6 to 4 cylinders. With turbocharging a much higher performance per cylinder is possible. There are various concepts such as the conventional turbocharger the twin-turbocharger or the sequential bi-turbocharger. Another component in gasoline engines is direct fuel injection and active cylinder management. This is understood as the activation or deactivation of cylinders. The camshaft is used to control these processes. In addition to the design of new engine concepts work is primarily being done on the reduction of friction. Friction reduction affects the entire drive train from the engine via the transmission to the tires. The aim is to reduce the gear transfer more power and reduce noise. In addition there are particularly high demands for example on cylinder liners bearings or gears.
