The first legislated exhaust (tailpipe) emission standards were promulgated by the State of California for 1966 model year for cars sold in that state, followed by the United States as a whole in model year 1968. Also in 1966, the first emission test cycle was enacted in the State of California measuring tailpipe emissions in PPM (parts per ...
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.
While aspects of their production can induce similar, less or different environmental impacts, they produce little or no tailpipe emissions, and reduce dependence on petroleum, greenhouse gas emissions, and deaths from air pollution. [2]
As the study notes, “Comparing real-world tailpipe particulate mass emissions to tire wear emissions, both in ‘normal’ driving, the latter is actually around 1,850 times greater than the ...
(Reuters) -The U.S. Supreme Court agreed on Friday to hear a bid by fuel producers to challenge California's standards for vehicle emissions and electric cars under a federal air pollution law in ...
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 ...
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.
The Environmental Protection Agency in April 2023 proposed requiring a 56% reduction in new vehicle emissions by 2032. US to soften tailpipe rules, slow EV transition through 2030 Skip to main content
