Stifling hot weather from global warming are threatening our wellbeing, and the cars that we rely so heavily upon, are a major contributor to global warming. All kinds of vehicles emit air pollutants such as carbon monoxide, nitrogen oxides, hydrocarbons as well as other air pollutants and greenhouse gases. Fortunately more modern and fuel efficient vehicles burn less fuel and generate fewer emissions.
In their efforts to find solutions, governments around the world require auto manufacturers to reduce emissions with more efficient engine combustion chambers while drivers themselves are responsible for maintaining acceptable emissions levels in their own cars. Automobile emission testing standards are in place to regulate emissions and actually set limits on the amount of pollution a vehicle can emit.
Measuring Emissions Mandatory before a Car is Sold
All cars sold in the UK, for instance, are required to undergo an official emissions test under EU law to ensure they meet the most recent emissions standards. These tests are required before a car be sold to the consumer. All new cars registered in the EU from September 2015 have to meet this standard. The test ensures consistency with all vehicles, requiring the vehicle to be fitted with equipment to measure emissions.
The vehicle performs a standardized drive cycle that is known as the New European Drive Cycle (NEDC), and this is made up of set acceleration/deceleration levels, all the while replicating a range of different driving conditions. With levels lower than the limits set for the Euro-6 standard, the car receives the Euro-6 approval certificate, and it can be sold. These tests are carried out in government-approved test facilities and are witnesses by a government-appointed independent approval agency.
Manufacturers of Engines Follow Test Procedures
In the United States, the tests are carried out by the manufacturer and the results are submitted to the US Environmental Protection Agency (EPA). They decide whether to accept these results or test the vehicle themselves. Vehicle emission testing standards are different to those in the EU.
The Environmental Protection Agency of the United States has adopted emission standards for almost every kind of engine, from automobiles to cruise ships, and to show compliance with these emission standards, manufacturers of all engines have to follow test procedures specified in the Code of Federal Regulations.
The Fight Continues
Reducing vehicle emissions is a critical step towards fighting global warming and with automobile emission testing standards in place, manufacturers are moving away from fossil fuel-powered vehicle dependence and moving towards electric cars and also towards alternative fuels in efforts towards restricting restrict vehicle emissions.
