GENEVA -- The world's largest supplier can't persuade customers to try its sintered-metal diesel particulate filter.
Robert Bosch GmbH confirmed it is not producing its soot-reducing technology, which it had aimed to launch this year.
"There is a shortage of filters in the market, so if Bosch can't sell its system then there is a problem," an industry source said.
The company says it will announce in the first half of this year when it will enter the market with a particulate filter.
"We have to be sure the car manufacturers will buy our technology," company spokesman Stephan Kraus said. "It is one thing to develop a technology, but we need customers."
ArvinMeritor Inc., Eberspaecher Group, Emitec GmbH, Faurecia SA and Tenneco Inc. already make particulate filters.
According to consulting firm Global Insight in London, an estimated 2.6 million European cars will be equipped with diesel particulate filters this year.
It forecasts 9.5 million annual filter sales by 2010.
