Analysis of emission reduction in VCR diesel engine using urea based catalytic convertor

Abstract Air pollution from mobile sources is a subject of widespread concern. By 2030, the number of vehicles on the road is expected to be close to 1300 million. Diesel engines are mostly used in industry because they produce higher torques at lower speeds, allowing them to perform heavy tasks. Incomplete combustion products such as CO, HC, NOx, particulate matter, and others result from incomplete combustion in diesel engines. These contaminants have a detrimental effect on air quality, the atmosphere, and human health, resulting in pollutant emission standards that are stricter. Several tests have been carried out to see whether other biofuels can be used in place of diesel. In this paper, solid urea catalytic converters are used to conduct various tests using a mixture of cucumber seed oil, gasoline, and a Nano additive (cerium oxide). The experiments are carried out in order to calculate and discuss the emissions of different incomplete combustion materials. Emissions values are plotted on graphs and compared to pure diesel emissions. The experiment was carried out on a four-stroke diesel engine with a single water-cooled cylinder that ran at 1500 rpm.
