WASHINGTON (Reuters) -U.S. President Joe Biden's administration is set to ease proposed yearly requirements through 2030 of its sweeping plan to aggressively cut tailpipe emissions and ramp up ...
Catalytic converters have proven to be reliable and effective in reducing noxious tailpipe emissions. However, they also have some shortcomings in use, and also adverse environmental effects in production: An engine equipped with a three-way catalyst must run at the stoichiometric point, which means more fuel is consumed than in a lean-burn engine.
The U.S. House of Representatives voted narrowly on Friday to repeal clean-vehicle rules adopted in March to cut tailpipe emissions by 50% from 2026 levels by 2032. House Republicans said the ...
The rules will cut tailpipe emissions in half by 2055, and the EPA claimed that they would also help the average driver in the U.S. to save $6000 in fuel and maintenance costs over the life of ...
One way the program would reduce costs is by taking advantage of on-board diagnostic (OBDII) technology that has been installed on new vehicles since 1996. The program will eliminate tailpipe testing of post-1999 vehicles and instead use the vehicle's own emissions monitoring systems. This system has saved consumers in 22 states time and money ...
The mechanism by which exhaust emissions are controlled depends on the method of injection and the point at which air enters the exhaust system, and has varied during the course of the development of the technology. The first systems injected air very close to the engine, either in the cylinder head's exhaust ports or in the exhaust manifold.
The Biden administration on Wednesday finalized one of the most important pieces of its climate agenda: new tailpipe rules for passenger cars and trucks that will decisively push the US auto ...
The long tailpipe is an argument stating that usage of electric vehicles does not always result in fewer emissions (e.g. greenhouse gas emissions) compared to those from non-electric vehicles.
