Heavy Duty Vehicles

The control of emissions from heavy duty vehicles is essential for the environment, because these vehicles emit a significant portion of the particulates and NOx from all diesel engines.
Even in the field of large-displacement diesel engines, the robustness of ceramic filters has proved to be a material advantage for diesel particulate filter systems.

Catalyzed filter systems on the basis of ceramic substrates possess a superb regeneration efficiency and favourable burn-off characteristics. This has been proven in large-scale practical applications. NGK has developed several types of cordierite DPF for heavy duty vehicles by adjusting mean pore size and porosity.
