Less Pollution with Euro 6 Diesels

Less Pollution with Euro 6 Diesels

Thinking of how cars affect the environment may seem to be a very 21st Century idea. But, the Euro 1 standard for engine emissions was actually first introduced in 1992. Since then, progressively more stringent Euro standards have been implemented, so that we now have the Euro 6 standards.

These standards are designed to oblige manufacturers to build engines more in tune with improving our air quality. The Euro 6 standards that all new petrol and diesel cars must meet, is currently the toughest yet. But what is required of a Euro 6 diesel engine?

Lower ‘NOx’ Emissions

Euro 5 regulations focused on exhaust particulates, which meant that diesel models needed to be fitted with exhaust particulate filters. Euro 6 regulations targeted a reduction in nitrous oxides, or ‘NOx’ emissions, as they are a significant cause of more greenhouse gases and air pollutants.

A Euro 6 diesel car must emit more than 50 percent fewer nitrous oxides than a Euro 5 diesel. The cap is 80 mg/km. Back in 2000, the nitrous oxide limit was 500 mg/km. It just shows how much the industry needs to have changed their car engines and their values. Because diesel engines naturally produce higher levels of nitrous oxides than petrol cars, it makes the Euro 6 regulations a real challenge to meet. Car manufacturers are having to invest in yet more new diesel engine filtration technology to clean up exhaust emissions.
