The Risks of NOx

It may cause not only bronchitis, pneumonia or respiratory disease but also brings the serious environmental problem such as photochemical smog and acid rain.

Consolidation of the regulation in NOx emissions

< Enforcement period of a permissible standard of NOx emissions >

•  New model of full-sized diesel vehicle : Enforcement from JAN 2014
(Old model of full-sized diesel vehicle : Enforcement from JAN 2015)
•  New model of small-sized diesel vehicle : Enforcement from SEP 2014
(Old model of small-sized diesel vehicle : Enforcement from SEP 2015)
※ The permissible level of NOx emissions will be strictly reinforced by 80% for full-sized vehicles from 2014
