Effect of Variable Turbocharger Pressure Ratio on Diesel Engine Emissions by Using Simulation Software

Abstract

The phenomenon of global warming is one of the most important problems facing us at the present time, which has not been treated so far, and that the root cause of this phenomenon is the greenhouse gases surrounding the globe, and hence the aim was to reduce the rates of these gases and know the causes of the occurrence and attempts To reduce or minimize these causes. Emissions from motor vehicles and power plants are one of the main reasons for the presence of greenhouse gases, so there has to be a solution that reduces these emissions, and here are the emissions from motor vehicles in general and diesel engine in particular. The engine was tested to reduce its emissions, and the method used was to use a turbocharger in the engine. A comprehensive study of these emissions and their different types, causes and methods of reduction was done by changing the speed of the engine rotation without the use of a turbocharger. The same study was carried out using a turbocharger at different pressure ratios and speeds until the pressure ratio and the speed required to produce as little emissions as possible.
