Complying with Emission Certification Standards

- Dec 06, 2018-

According to the Tier 2 standard, vehicles are classified into emission standards called bins. There are currently 11 boxes, from 1 (the cleanest vehicle) to 11 (the most polluted). Box 1 vehicles are equivalent to zero-emission vehicles; 5 are ordinary cars (all new cars must meet this nitrous oxide emission standard), and 11 are for very large trucks. On the second floor, light trucks like SUVs are also subject to the same emission standards as passenger cars, regardless of weight.


So, how do you make your car greener? There are several ways.

First, find out how your vehicle is classified according to emission standards. This information may be available on the car manufacturer's website, and many car window stickers have emission levels. However, all newer cars have a mandatory label that identifies emission standards.

Second, check your car every year and make sure it meets your state's emissions standards. During the inspection, the mechanic places your car on the dynamometer - a car treadmill that allows it to travel at different speeds while maintaining the proper position - a device attached to the tailpipe. If the car releases excess hydrocarbons, carbon monoxide or nitrogen oxides, your car will not pass the test.

In addition to the fact that many state laws require drivers to conduct annual inspections, as well as the fact that the car store ensures that your brakes and other mechanical and electrical components work properly while you are working, this test will prevent you from driving in a smoky clunker. What's more, these cars usually get better fuel economy, so you don't have to worry about wasted fuel on the road.

For those looking to purchase a new car or a recently built used car, there are many models available with low emissions in mind. For instance, the Toyota Prius is a bin 3 car, while the Honda Civic Hybrid is even lower at bin 2. Ford's Escape Hybrid is a bin 3 vehicle, which is an impressive rating for an SUV. Under the tough California emissions standards, the non-hybrid Toyota Yaris and Honda Fit are both considered Ultra-Low Emissions Vehicles.

One day, we may all be driving electric or hydrogen-powered cars that do not emit chemicals that can damage our health or the environment. But before that, we only need to know as much as possible about green driving to ensure that our cars are fuel efficient and that our old cars are not too polluted.
