Diesel emission standards

Diesel emission standards are regulations set by governments to limit the amount of harmful pollutants, such as nitrogen oxides (NOx) and particulate matter, that diesel engines can emit. These standards aim to reduce air pollution, protect public health, and improve air quality. Manufacturers must use advanced technologies, like filters and exhaust treatment systems, to meet these limits. As standards tighten over time, engines become cleaner and more environmentally friendly, helping to minimize their impact on climate and health while maintaining vehicle performance.
