A leading supplier of diesel cold-start technology has unveiled plans for a new platinum-based sensor solution for use in powertrains and exhaust systems.

BERU is developing a number of high temperature sensors (HTU), which it believes will eventually be ideal for inclusion in turbochargers and diesel particulate filters.

The platinum element of the sensors allows them to cope with temperatures above 926 degrees C and perform their duty of informing the engine control unit of the filter loading rate.

As a result, the regeneration process can be started effectively, while the turbocharger blades also avoid damage.

Dr Thomas Waldhier, Chairman and CEO of BERU, explained that sensors of this type are playing an increasingly important role in optimising engine performance and reducing harmful exhaust emissions.

He said: "Today's cars and commercial vehicles rely on up to 30 sensors performing a wide variety of functions in the powertrain and exhaust system alone.

"With years of experience in sensor technology and expertise in metal processing and plastics engineering, BERU is positioned to offer innovative solutions for this growing technology market."

In September 2009, BERU - which was established in 1912 - became a 100 per cent subsidiary of US automotive supplier BorgWarner.
