Emission characteristics of a compression ignition engine using different catalyst

Catalytic converter with different catalyst for compression ignition engine to reduce pollute gases is chosen for present work. The emphasis is given on hydrocarbon (HC), carbon monoxide (CO) and oxides of nitrogen. The catalytic converter was designed and developed with different catalyst. The pellets are developed as catalyst The pellets are coated with copper oxide (CuO), cerium oxide (CrO2) and zirconium dioxide (ZrO2). Pellets are held together in a circular housing at two ends of the converter shell. Cylindrical spacer was used in between circular housing containing pellets to vary the distance and to reduce back pressure on the engine. Experiments were carried out on computerized kirloskar single cylinder four stroke (10 B.H.P, 7.4 KW) diesel engine test rig with an eddy current dynamometer. The converter was tested with different catalyst. There is considerable reduction in HC, CO and NOx.
