Intertek has expanded its engine-emissions testing services in the US with the addition of a heavy-duty dilute-emissions tunnel at Intertek Automotive Research.
This enhanced capability better helps their clients evaluate compliance with US EPA requirements for exhaust-emission control.
The Constant Volume Sampler (CVS) emissions tunnel is a full dilute heated system that, coupled with the gaseous and particulate-sampling equipment, enables accurate low-level measurement capabilities.
Manufacturers of heavy-duty engines and engine-related components and technologies will be required to conduct testing according to EPA regulation Part 1065 beginning 1 July 2010.
The emissions tunnel allows Intertek to provide faster, more detailed evaluations for clients.
The tunnel supports the certification of spark ignition (gasoline, natural gas and LGP) and compression ignition (diesel) engines to transient emissions standards for engines ranging from 50HP (37kW) to 600HP (450kW).
Particulate emissions are collected on a filter and measured gravimetrically.
In addition, the following dilute gaseous emissions are measured: carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxides (NO/NOx), total hydrocarbons (THC) and methane (CH4).
The expanded engine-emissions testing capability is complemented by an on-site chemistry laboratory that provides chemical speciation of the dilute exhaust to EPA and other international standards.
