In modern existence, companies have focused on developing innovative materials with superior qualities to those now accessible. The present study aims to fabricate and evaluate the mechanical properties of AA2219 alloy reinforced by Silicon oxide (SiO2) particles in this regard. Liquid metal (Stir) casting was used to make the AA2219/SiO2 composites. The quantity of reinforcement introduced to the AA2219 was varied from 0 to 9 wt% in the steps of 3. The AA2219 alloy and its SiO2 composites were subjected to hardness and tensile tests following ASTM Standards. The findings demonstrate that SiO2 filled AA2219 alloy boosted SiO2 composites had better mechanical characteristics than the AA2219 base alloy. [ABSTRACT FROM AUTHOR]

Increased demand, price rates, and the depletion of fossil fuels are occurring today. Interest in the development of biodiesel is therefore increasing. Since the mahua is inedible oil and can not be used for domestic purposes, and the mahua fruit kernel contains 35-40 percent of the oil, which can be a major source of biodiesel. In India, mahua trees are abundantly available. The process of transesterification has been used to prepare Mahua biodiesel and the properties of neat and blended mahua biodiesel are studied. It contains approximately 42.1 percent saturated and 57.9 percent unsaturated fatty acids. However, after transesterification, the viscosity of crude mahua oil is reduced, but it is still more than pure diesel. Then, the physiochemical properties of mahua oil made the properties of diesel fuel relevant. Besides, Mahua biodiesel blended with mineral diesel in volumetric percentages and blended biodiesel properties assessed against the relevant standards. In this research, the performance and emission characteristics of the compression ignition engine shall be determined by gasoline fumigation using mahua biodiesel oil. Performance and emission characteristics of the engine carried out with and without exhaust gas treatment by the introduction of a water scrub method and a silica gel chamber. Best of the biodiesel blends identified by optimizing the results and that of the biodiesel blends investigated by gasoline fumigation, which is further tested by low-cost exhaust gas post-treatment by water scrubbing and silica gel.
