Environmental research center at University of Technology hold a seminar on "Effect of Internal Combustion Engine Exhausts on Air Pollution"
Asst.Lect.AbdulRahman Shaker showed that The increase in the use of means of transport such as aircraft, ships, trains and cars have greatly contributed to the movement service of man facilitate and use of time. However, this important development led to the emergence of many problems and adverse consequences on human health and all living things and the environment, as a result of pollution from these means, especially exhaust emissions of engines.He added that internal combustion engines of all types and uses constitute a major source of air pollution because of the harmful emissions of these engines which have negative effects on humans and other organisms.
He also pointed out that the most important of these emissions are nitrogen oxides (NOX), carbon monoxide (CO), carbon dioxide (CO2), unburned hydrocarbons (HC)and smoke. Also, the most important environmental effects of fuel combustion products are global warming and acid rain, which lead to the elimination of biodiversity and causes many diseases in humans, there are several ways to reduce exhaust emissions while maintaining engine performance, he said. Some of the engine parameters such as compression ratio, exhaust gas recycling, injection timing and injection pressure are changed. Biodiesel can also be used in different proportions and mixed with pure diesel fuel, as well as the addition of some chemicals to fuel, all of which help reduce emissions and thus reduce air pollution.
The Department of Control and Systems Engineering at the University of Technology in cooperation with the Ministry of the Interior Department of Narcotic Drugs and Psychotropic Substances held a scientific symposium on the fight against drugs and its hazards in the presence of Prof. Azad Rahim and my staff and students section.
The seminar came within the definition of this deadly scourge in society.
The head of the department, Prof. Azad Rahim Karim thanked the Directorate of Combating Drugs and Psychotropic Substances in the Ministry of Interior.
