What is the emission certification standard?

- Dec 03, 2018-

Eco-friendly car owners are paying more and more attention to the problem of automobile exhaust pipes. When the engine burns fossil fuels, it emits a variety of potentially harmful substances: carbon monoxide, greenhouse gases, sulfur oxides, nitrogen oxides, hydrocarbons, and so on.

What do these substances mean for the environment and health? The news is not good: carbon monoxide makes it harder for blood to carry oxygen and cause heart and lung disease. Sulfur dioxide can cause acid rain. Nitrogen oxides cause yellow-brown haze to hover over crowded cities. Carbon dioxide can cause terrible greenhouse effects - gas and heat capture makes the atmosphere warmer than it should be - hydrocarbons can cause cancer

 

In other words, we are all driving machines that destroy our health, the environment, and - as many scientists believe - have made a significant contribution to global warming.

 

We still have a few years of affordable and ready-to-use cars that don't emit harmful substances like hydrogen fuel cells or all-electric cars. Until then, we can all take steps to reduce fuel consumption and car pollution. For example, we can focus on fuel efficiency and eco-driving by purchasing low-emission vehicles and ensuring that our cars pass many state-issued annual emissions checks. These tests test the safety and mechanical status of your car and ensure that your car does not cause too much pollution, which is especially important for older cars that lack modern emission control technology.

 

Due to their environmental hazards, vehicle emissions need to be tightly controlled and monitored to prevent the atmosphere above the roads and cities from being filled with smoke. To this end, the federal government and some states have established emission certification standards - regulating the harmful emissions that vehicles can legally release.

 

In this article, we'll discuss how the emission certification standards work and learn more about green driving.
