What are the euro 4 grade fuels? | Effects of sulphur on the atmosphere and people

FuelThe euro 4 grade petrol is made available in the cities like Hyderabad and other 13 cities in Andhra Pradesh by April 1st.  They had decided to provide the euro 4 grade petrol and diesel across India from October 1st. They had increased the petrol rates by Rs.0.50 and diesel rates by Rs.0.26 for the euro 4 grade. They increased the petrol rates by Rs.0.26 and Rs.0.21 for diesel for the euro 3 grade petrol.

  • The oil companies and the government companies are making the changes in the purifying processes to provide high quality petrol. They had spent 32 thousand crore rupees.

What are euro 3 and euro 4?

The euro 3 and euro 4 are the rules which will tell the levels of the pollution released from the vehicles. According to these regulations, the levels of the sulphur should be reduced from the vehicles and so the pollution is also reduced. The levels of the sulphur is reduced to 350PPM in euro 3 and it is reduced to 50PPM in euro 4. The sulphur content is reduced by 550-350 PPM in the petrol and diesel used in India.

  • It is very important to reduce the pollution due to vehicles and it is very useful to reduce the sulphur content. The pollution is reduced by reducing the sulphur content and the particles like carbon monoxide and nitrous oxides are reduced in the air. The sulphur should be reduced to 10PPM to reduce the pollution by 95%.
  • The manufacturers of the cars are making modifications in the engine to reduce the pollution and the high pressure injection system reduces the pollution by the diesel engine and if the sulphur levels are more in the diesel, then this technology is not useful.
  • The maintenance of the vehicle increases if the sulphur content is more in the diesel or petrol used. The piston ring and the exhaust systems spoil soon due to more sulphur.
  • There are many advantages of the sulphur content is reduced to 50PPM for the vehicles and pollution.

Health problems:

The sulphur dioxide is produced due to oxidation of the sulphur in the fuel and the materials like nitrogen oxide and carbon monoxide also increase due to the increase in the sulphur content in the fuels. There will be increase of the pollutants in the air and they lead to the breathing problems, heart problems and the rate of sudden deaths increase. The global warming increases and the paintings of the buildings get damaged. The amino acids increase and the acid rains will also increase. As a result the crops are affected.

In foreign countries:

They are trying to reduce the sulphur content to 10PPM and this was started in 2005.

  • The diesel which consists of 50PPM of sulphur is available in Sweden from 1990 and they had produced the diesel with 5PPM of sulphur in 1992.
  • They had introduced the euro 4 fuels in 2008 in Argentina.
  • They had reduced the sulphur levels to 15PPM in 2006 in Canada.

Where does the sulphur come from?

The petrol and diesel are manufactured from the crude oils and they contain the sulphur. The content of the sulphur varies according to the sources and in different areas. They are called as sweet crude if the sulphur content is less and they are called as sour crude if the sulphur content is more. The sulphur content is less in the fuels which are manufactured in Nigeria. The content of sulphur is more in the Middle East regions and the sulphur content increases from 1 to 3% suddenly in the crude oils.
