EC Releases Euro 5 Specifications for Comment - Green Car

Jul 15, 2005 · Methane (CH4) is non-toxic and has a negligible contribution to ozone formation compared to other hydrocarbons (NMHCs). Definition of an NMHC standard is an important step towards world-wide harmonisation of emission standards, as NMHC standards already exist in North America and Japan, as well as in Europe for heavy duty vehicles.

A method of assessing non-methane hydrocarbon (NMHC) conversion efficiency in a diesel after-treatment (AT) system having a diesel oxidation catalyst (DOC) arranged upstream of a diesel particulate filter (DPF) includes regenerating the AT system. Additionally, the method monitors DOC inlet and outlet temperatures during the regeneration.

Jul 24, 2015 · Spark-ignited engine generators in non-ESP applications including generator sets running on natural gas, LP, or methane collected from landfills, sewage treatment or coal seams. While these fuels are naturally clean-burning and compliant for PM, they do produce enough NOx to require exhaust after treatment for Tier 4 Interim and Tier 4 Final in non-ESP applications.
