DESIGN AND MODELLING OF DIESEL PARTICULATE FILTER TO REDUCE THE EMISSIONS FROM CI ENGINE

The present study deals with modelling of a catalytic converter system for a compression ignition engine. Many models fabricated and tried to fit with an existing diesel engine. Since the compatibility of a diesel engine, exhaust with DPF is essential as the pressure gradient need to be maintained. The size of the diesel particulate filter is also important since the fabricated model size need to be sufficient to handle the gasses without affecting the flow and engine performance. This work consists of checking the fuel emission after changing the existing catalytic converter with disc mesh coated with titanium oxide, copper nitrate and cerium oxide. Since these are readily available, are cheap, and fabrication is also easy. Hence, the cost is reduced. The engine test results showed that the emissions reduced with the new fabricated catalytic converter comparing with diesel and Algae biodiesel blends.
