Conclusions
Upcoming EU VI and Stage IV legislation will require a combination of
DPF and SCR technologies
The challenge is the integration of all required functions into a compact,
robust and cost efficient aftertreatment unit Tenneco owns all simulation and testing tools for effective EU VI and
Stage IV system integration
TRUE-Clean and Vaporizer Technologies are cost efficient and
reliable solutions for active DPF regeneration
Urea SCR is mainstream technology for near future limits
Tenneco offers turnkey urea dosing & injection system
Tenneco develops a HCLNC system as an alternative to urea SCR
