The revised emission testing laws in the country are established in response to the global warming problem. One of the services that the automotive repair industry can introduce in line with the emission testing laws include exhaust emissions testing. It emphasizes the need for the industry to ...
Though the law will require emissions testing of all diesel vehicles, from tractor trailers to excursion buses, it will have no effect on sport utility vehicles, almost all of which are gasoline powered, and will not be sub- jected to emissions-control standards as stringent as they are for ...

CMAQ v5.2 was first run over a 12 km × 12 km grid based on DPM emissions inputs from the National Emissions Inventory [51]. Next, the AERMOD dispersion model was run for each source using the same inputs but with receptors distributed over census tract centroids. Finally, ...
let to unwanted scrutiny for the EPA. Its testing procedures have been criticized for being predictable and outdated, making it relatively easy for VW to cheat. What's more, the EPA did not initially uncover the problem; researchers at West Virginia University did, using on-road testing. ...

The emissions of HC, CO and smoke opacity reduced with the increase in the DEE mixture whereas the NOx release increased. Lobo et al. [45] evaluated the use of biodiesel in a diesel engine, as well as its effect on performance and combustion-related metrics. To compensate for these ...
Reuters cited Volkswagen as saying the EA288 engine did not have a "defeat" device to beat emissions testing. We will update with new information as it becomes available. General Motors and Toyota had their massive scandals. Now it’s Volkswagen’s turn. The company, which owns 70 per...
As the EPA increased its regulations on ever-cleaner diesel emissions it seemed the SD70ACe and its 710 prime mover were safe as the engine met later Tier III standards. However, when Tier IV standards went into effect on January 1, 2015 Caterpillar/Progress Rail was unable to make the pri...
Biomass-based diesel is defined as a renewable transportation fuel, transportation fuel additive, heating oil, or jet fuel that meets the definition of either biodiesel or non ester renewable diesel that reduces GHG emissions by 50% or more.
