3 You may conduct PM testing as follows for 2007: i Test vehicles may be selected from a vehicle fleet that you own or otherwise directly control.
EPA is publishing this rule without a prior proposal because we view this action as noncontroversial and anticipate no adverse comment. Set the zero and span of the smoke opacimeter recorder. Due to unexpected issues in the gaseous emission test program and the lack of other resources, all work on the PM test plan and subsequent test program had to be postponed. Mechanism Engine Emissions and Emissions Measurement Hydrocarbon Formation in Combustion Processes.
When the light source is an incandescent lamp, the receiver should have maximum response in the range 550 nm to570 nm wavelength as is for the human eye. Does This Action Apply to Me? Thermal Reactions in the Exhaust System. The last issue relates to regulatory requirement to delay the PM measurement program if fundamental technical problems were discovered as described in the preceding paragraph. The rule imposes no enforceable duties on any of these governmental entities.
Finally, we described how we had successfully used the same prototype system to measure PM emissions over NTE events while traveling cross-country in a particulate trap-equipped truck using ultra-low sulfur diesel fuel.
, 2006 through 2008, as described above.
While unexpected, the lack of overall validation for the three methods is not necessarily surprising given the enormous amount of laboratory-based and on-vehicle testing, the number of possible errors and the model simulations i.
Many vehicles manufactured post-1980, and all models manufactured after 1996 have some form of on-board computerized diagnostic systems OBDs.
