Exhaust EmissionsTask 3 P4Petrol and diesel engines work in slightly

Exhaust Gas Emissions Task 3 P4 Petrol and Diesel Engine operate in a slightly different way and operate in different ways to burn different fuels and produce different exhaust gases and different diesel engines burning different fuels so different rows are produced I will. Compared to gasoline engines, diesel engines produce small amounts of unburned and partially burned fuels but produce more nitrogen oxides and large amounts of smoke. These particles are composed of soot, hydrocarbons, sulfur-based chemicals and volatile organic compounds.

What is diesel exhaust? When the engine burns diesel fuel, diesel exhaust gas is generated. It is a complex mixture of thousands of gases and particulates (commonly known as soot) containing over 40 toxic air pollutants. These include many known or suspected carcinogens such as benzene, arsenic, formaldehyde and so on. It also contains other harmful contaminants including nitrogen oxides (components of urban smog). How do people contact diesel exhaust? Because diesel exhaust particles and gas are suspended in the air, as long as someone inhale the air containing these substances, they are exposed to pollutants. Whether you are rural or urban, the popularity of diesel engines makes it nearly impossible to avoid exposure to diesel exhaust or its by-products. However, people living in urban areas and industrial areas are exposed to this pollutant.

What measures are taken to reduce the health risk of diesel exhaust? Improvements in diesel fuel and diesel engines have reduced emissions of several pollutants related to diesel emissions. However, diesel exhaust is still one of the most common and toxic substances in California's atmosphere. After complete implementation, the ARB diesel risk reduction program will reduce particulate emissions from diesel equipment by 75% (compared to 2000) by 2010 and 85% by 2020. This plan reduces the emissions of particulate matter by about 90% through cleaner combustion of diesel fuel, the use of particle capture filters to improve existing engines, and the application of new technologies in advanced diesel engines , It is required to use alternative fuels.
