'Tailpipe' emission standards specify the maximum amount of pollutants allowed in exhaust gases discharged from an internal combustion engine. Tailpipe emission standards were first introduced in California in 1959 to control CO and HC emissions from gasoline engines.

Are tailpipe emissions bad?
All tailpipe pollution is a problem, but diesel fumes from idling cars, trucks, and buses are especially harmful. Not only can they contribute to climate change, but they also have been linked to a myriad of health problems such as asthma, emphysema, lung cancer, and heart disease.
What are tailpipe and upstream emissions?
What is the difference between tailpipe and upstream emissions? Vehicle tailpipe emissions are the GHGs your car produces when driving. Upstream emissions are the GHGs associated with the production and distribution of gasoline and electricity.
What are tailpipe pollutants?
Overview. Greenhouse Gas Emissions. Greenhouse gases (GHGs) are emitted from the tailpipes of cars and trucks that combust fuel. Once GHGs are released, they can stay in the atmosphere for 100 years or more. GHGs act like a blanket around Earth, trapping energy in the atmosphere and causing it to warm.
Why is there GREY smoke coming from my exhaust?
Grey smoke from the exhaust: This could be excess oil, a PCV valve failure or a transmission fluid leak on automatic cars. ... In diesel cars it's more likely to be soot build-up or the diesel particulate filter cleaning itself.
What is the primary cause of harmful tailpipe emissions?
Tailpipe emissions are a serious threat to human and environmental health. The combustion of petroleum-based fuels results in the release of noxious chemicals into the air.
What comes out of a muffler?
The three main pollutants are water vapor, nitrogen, and carbon dioxide. As the exhaust gases are leaving the chamber, the carbon dioxide and water are getting mixed together. The more the engine cools down, the water condensation in the exhaust becomes visible to those from the outside.
Is car exhaust matter Yes or no?
The exhaust system is an essential component of your vehicle. It takes burned gases in the engine and directs them away from the cabin, you, and your passengers. Without it, these chemical compounds would have nowhere to go once they ignite; furthermore, they would build up in the engine compartment or cabin.
What are most vehicle emissions?
Greenhouse gas emissions from transportation primarily come from burning fossil fuel for our cars, trucks, ships, trains, and planes. Over 90 percent of the fuel used for transportation is petroleum based, which includes primarily gasoline and diesel.
What is a good CO2 tailpipe reading?
The higher the CO2 level, the more efficient the engine is running. Optimum CO2 is 12% to 15 %. CO2 can be used as an efficiency meter of the engines combustion efficiency. When there is a problem that affects the combustion process, the CO2 will drop below 12%.
What is tailpipe CO2?
The tailpipe CO2 emissions measurement has been set to define the vehicle fuel consumption. It's calculated through the so-called “carbon balance”, summing up the carbon content from CO2, CO and THC (also measured) and converted to a fuel quantity.
How can I reduce NOx emissions in my car?
Fuel switching is the simplest and potentially the most economical way to reduce NOx emissions. Fuel-bound NOx formation is most effectively reduced by switching to a fuel with reduced nitrogen content. No. 6 fuel oil or another residual fuel, having relatively high nitrogen content, can be replaced with No.
Do vehicles consume more fuel in summer?
One of the main reasons your car uses less fuel during the summer is because of the air temperature. As you probably know, it takes more than fuel to run your car—the fuel needs air, specifically oxygen, to help it burn.
What are the gases emitting from the tailpipe that contains pollutants?
Vehicle exhaust emissions consist of the remnants of atmospheric air, carbon dioxide (CO2), water vapor, and numerous compounds in either particulate or gaseous form, the majority of which result from the incomplete combustion of fuel.
