1. Europe: In the European Union (EU), the maximum sulfur content in diesel fuel for CRDI engines is 10 parts per million (ppm) as per the Euro 6 emission standard. This regulation aims to reduce emissions and improve air quality.
2. United States: The United States Environmental Protection Agency (EPA) has set a sulfur limit of 15 ppm for diesel fuel used in on-road vehicles equipped with CRDI engines. This standard was introduced as part of the EPA's clean diesel regulations.
3. Japan: In Japan, the maximum sulfur content in diesel fuel for CRDI engines is 10 ppm as per the country's emission regulations. This limit helps in controlling emissions and protecting the environment.
4. China: The sulfur content limit in diesel fuel for CRDI engines in China has been gradually reduced over the years. Currently, the standard set by China's Ministry of Ecology and Environment is 10 ppm for diesel fuel used in most regions.
5. India: In India, the Bharat Stage (BS) emission standards regulate the sulfur content in diesel fuel. The current BS VI emission standard, which came into effect in 2020, mandates a sulfur limit of 10 ppm for diesel fuel used in CRDI engines.
These sulfur limits aim to reduce the emission of harmful pollutants, including sulfur oxides (SOx), which can have adverse effects on human health and the environment. Lower sulfur content in diesel fuel helps in improving air quality, reducing engine wear and tear, and extending the life of emission control systems in CRDI engines.
