Gasoline and diesel are the most widely used fuels, and efforts are being made to revise the standards set for car fuels to meet stricter gasoline and diesel standards. The purpose of considering these standards is to ultimately reduce the consumption of these fuels for humans and the environment with less pollution. Undoubtedly, increasing the quality of fuel consumption of cars plays a very important role in improving the air quality of metropolitan areas and thus the health of the residents of these cities.
Diesel cars now account for 50 percent of the world's fuel consumption. These engines use diesel. Experts at Black Ruby Caspian Energy Development Co are trying to apply the same standards for gasoline in diesel. Gasoline also contains compounds that increase the emission of pollutants. One of them is sulfur compounds. Many of the things that have been considered in determining gasoline standards can be done more easily for diesel.
The most important pollution of diesel is due to the presence of sulfur compounds. According to the Euro 2 standard on diesel, the permissible amount of sulfur in this fuel can reach 5000ppm or even higher. Now, the permissible amount of sulfur in diesel has reached less than 50 ppm according to the new standards, which can be provided to the stations in the refineries of big cities based on these specifications.
Euro 4 emission standards (diesel)
Carbon monoxide: 0.50g / km
Nitrogen oxides and hydrocarbons: 0.30g / km
Titanium: 0.025g / km
