What is an Emissions Test (and Why is it Important for the Environment)?

Saving the environment is something everyone needs to be thinking about. After years of abusing Mother Earth, we have discovered that, if we’re not there for the Earth now, she won’t be there for us later. As a result, everyone is redoubling their efforts.

The U.S. Environmental Protection Agency (EPA) is at the forefront of the cause. Established in 1970, the government organization is tasked with handling environmental matters.

Reducing emissions has been a primary focus. As a result, they require vehicles to submit to a wide array of analytical testing at the National Vehicle Fuel Emissions Laboratory (NVFEL) in Ann Arbor, Michigan. Assessments are conducted to ensure emissions are not doing excessive harm to the atmosphere.

Almost every U.S. state and its many cities and counties now require emissions testing. Read on to find out more about the NVFEL and its efforts to clean up the environment.

NVFEL Mission

The NVFEL is a state-of-the-art facility that utilizes an expert staff and specialized equipment to measure emissions from a variety of engines and vehicles. They integrate years of research and testing to develop emissions standards and ensure compliance. Their mission is to protect people and the environment from transportation-based pollutants.

Here are some of the steps they take to meet environmental goals.

·      Testing new and used cars, heavy duty engines, and light trucks to ensure they meet emissions standards now and throughout their lifetime.

·      Conducting tests and research to ensure emissions standards are up to date.

·      Developing and implementing testing standards for measuring vehicle and engine emissions.

·      Assessing potentially effective emission reducing technologies.

6 Types of NFVEL Emissions Tests

The NFVEL administers a variety of tests for all types of vehicles as follows:

Light Duty Vehicle Emission Testing

This type of testing is administered to cars and light trucks. The vehicles are placed on a chassis dynamometer under controlled conditions made to simulate the on-road experience. The vehicle drives on the dynamometer rollers as chemical analyzers measure the pollutants produced from the exhaust.

Heavy Duty Chassis Testing

Ideal for on road trucks and buses up to 80,000 lbs., the dynameters used in this application perform whole vehicle tests to measure greenhouse gas emissions and fuel efficiency.

Heavy Duty Engine Testing

Heavy duty engine testing is used to measure emissions in small to large engines ranging from those used in garden tools to engines you would find in heavy duty trucks and buses.

On Road Emissions Testing

Portable Emissions Measurement Systems are used to glean deeper insights on in-use emissions performance of vehicles and nonroad equipment under typical operating conditions.

Small Nonroad Spark Ignition Engines

This type of emission testing is conducted on small spark ignition gasoline engines such as those found in garden and lawn tools and small generator sets.

Fuels and Chemicals Analysis

The NVFEL facility features a Fuel and Chemistry Center that tests standard fuels, experimental fuels, and analyzes non-regulated pollutants.

With on road vehicles being a major source of pollution, it’s good to know that the NVFEL has tests in place to ensure things don’t get out of hand. With greener vehicles on the road, we just may get to our environmental goals. With everyone doing their part, the earth will be a cleaner place to live in.
