Tenneco Launches Retrofit Diesel Particulate Filter; Toyota Europe Chooses it for Entire Range
31 May 2006
Tenneco is launching a retrofit diesel particulate filter (DPF) for the European independent aftermarket in advance of the introduction of European Union (EU) legislation and tax incentives on retrofit units that come into effect in The Netherlands this July.
The Tenneco Walker-brand DPF features a lightweight foam filter coated with precious metals and combines the catalytic converter and DPF into one unit. This allows installers to replace the existing catalytic converter with the DPF without adding additional weight and without disturbing the vehicle’s entire NVH (noise, vibration, harshness) profile.
Unlike DPFs applied in original equipment systems in which a periodic regeneration process is controlled by the engine management system, aftermarket retrofits need to be able to work in an open loop system without the engine management system to trigger the regeneration. The design and the coating therefore support continuous regeneration of the filter.
Toyota Europe has selected the DPF technology for its complete European diesel car range. Tenneco will manufacture the full exhaust system, including the DPF, for part of the Toyota range and supply DPF units as a Tier 2 supplier to Sango and Arvin Meritor for the balance.
Tenneco has delivered over 1 million original equipment (OE) DPF units to the European car manufacturers since it produced the first DPF for the Peugeot 406 in 2000. With EU pressure on reducing emission limits growing, we see significant potential for a fully-homologated, highly efficient retrofit product that offers consumers the opportunity to benefit from tax reduction incentives while avoiding potential driving bans in the event of particulate matter alerts. In addition, the presence of a retrofit DPF has the potential to increase the resale value of older car—Mark Frissora, Chairman and CEO, Tenneco
Walker DPFs are fully-homologated and come with installation certificates to facilitate consumer access to EU tax incentives. The size of the European diesel car fleet makes retrofit DPFs a significant new aftermarket business opportunity.
Tenneco was one of the first global suppliers to offer both additive and catalyst-coated diesel particulate filter technologies in series production for Europe’s vehicle manufacturers. It first began production of original equipment diesel particulate filter technology in 2000 in conjunction with PSA Peugeot-Citroen for the Citroen C5 and Peugeot 406 diesel passenger vehicles.
