Experimental Analysis of Diesel Engine Performance and Emissions with the Integration of Cyclonic Separator Device

The high population density and demographic dynamics have triggered a boom in the uptake of larger and more fuel-efficient diesel goods vehicles because diesel is cheaper than gasoline. Nevertheless, availability of diesel engines has lead to an increase of pollution especially in the urban area. This research examines whether a cyclonic separator which is an attachment device mounted on the vehicle exhaust system can sufficiently reduce particulate emissions from diesel engines. Thanks, the cyclonic separator is used to gather particles of size from 1μm to 50μm, to control the emission of diesel exhaust pollutants. Although we find that the utilization of the device decreases the pollution emission, our study shows that the installation of the device causes backpressure leading to a marginal reduction in thermal efficiency of between 0.8% to 1.01%. Nevertheless, the cyclonic separator can be considered one of the possible means to solve the problem of reduction of emissions of diesel engines and protect urban environment from pollution.
