This study investigates the effect of biodiesel namely 20MOME (80%diesel+20%mahua oil methyl ester) on a kirloskar, single cylinder, direct injection diesel engine. Performance and emission characteristics like break thermal efficiency, exhaust gas temperature; Carbon monoxide (CO), unburned hydrocarbon (UBHC) and oxides of nitrogen (NOx) emissions were determined for 20MOME and compared with diesel fuel. The results showed that the engine performance under biodiesel blends were similar to that of neat diesel fuel with nearly the same brake thermal efficiency, and slightly higher fuel consumption. The carbon monoxide and hydrocarbon emissions decreased significantly compared to neat diesel fuel whereas the oxides of nitrogen increased.Keywords

This paper investigates the Eigen values and Eigen vector of lamina and laminate of composite plates. Lamina plays a significant role in composite laminated structures; as a result, it’s important to select an exact orientation lamina to avoid maximum amplitude. The structural stiffness and mass matrices were obtained from classical laminated plate theory and non conformal rectangular element theory. The Eigen values and Eigen vectors are derived based on vibration theory. The simply supported square plate element is designed analytically using above theories and computed in MATLAB, the variation of frequency and modes between lamina and laminate were studied for different orientation. Then the element assembled to global element level to study the changes in their vibration and compared. Finally, it also represents the first derivative frequency change with respect to fibre volume fraction and compared.
