The present study is to seek the prospect of pine oil to be used as a substitute to that of diesel fuel. Pine oil is certainly available in India and it has found to be the least viscous oil due to which it has potential for utility as an alternative fuel may be explored.Therefore, due to low viscosity, no further transformation is done and the study is carried out by its direct blending with diesel fuel in various proportions. In this study, a comparative evaluation and analysis of physio-chemical properties of pine oil, its various blends with diesel has been done. Experimental analysis of performance and combustion of the blended fuels on CI engine has been conducted aiming to maximum substitution of pine oil to diesel in order to reduce emissions and improve quality of exhaust gas without decreasing the performance of the engine.

Robotic arms have become a crucial part of every industry, ranging applications from welding or assembly of various components to works that involve high precision. To enable small industries to take advantage of robotics and automation, optimization of the design through analysis is very essential. It also reduces the cost of the product and increases the life cycle. This study comprises the design and analysis of a human arm type robotic arm under different loading conditions using Finite Element Analysis (FEA) simulation. A minimalistic approach has been adopted throughout the design of the robotic arm. In this paper, the Computer-Aided Design (CAD) model of the robotic arm is developed using Creo Parametric software and is exported to Ansys. From the results of this study, it is found out that material properties play a vital role in different loading conditions. Thus, optimization of design is achieved by observing the effect of changing materials, using Ansys Workbench. Finite...
