Now a day’s so many problems raised to use biodiesel in I.C engine such as High Nox formation, Low brake thermal efficiency, less combustion characteristics etc. In our Experiment we could minimize this kind of problems by Modified injection systems, like Increases Injection pressure (210 bar), Retard Injection timing (25° Btdc) Through all parameters Experiment were carried on Direct Injection Single cylinder C.I engine using blend of biodiesel (palm seed oil B30). Here diesel as well as Biodiesel blend with modified injection parameters are analyzed and compared with original condition of engine. During Experiment, Minimized NOx formation up to 16% in Diesel and 10% in biodiesel less than the Original condition. While SFC 3.4 % decreased in diesel, 10% increase in biodiesel and also nearest 2 % Improved Brake thermal efficiency than original condition. Bot...

In this study, a static simulation is performed & presented related to crankshaft of a 4-stroke, single-cylinder petrol engine. This study addresses the tested single-cylinder engine crankshaft. It consists of static structural analysis of single cylinder engine crankshaft. Identifies and solves the problem using modeling and simulation techniques. The theme was chosen because of the growing interest in higher loads, lower weight, and greater efficiency. A three-dimensional model of petrol engine crankshaft is created using the CATIA software. Finite Element Analysis (FEA) is performed to get the magnitude of stress in the critical location of crankshaft. The preliminary static analysis is performed for the base design using ANSYS. The boundary conditions are applied according to the engine installation conditions. The analysis is performed to find the critical position on the crankshaft. Deformation, Von Mises stress obtained from the FEA study. Same Crankshaft is used for topological optimization. The same contour conditions are used for further study. The primary objective of the study is to minimize the weight of a crankshaft. Optimization is implemented by considering different production, feasibility and cost limits. The optimization process include geometry changes compatible with the current engine, reduced weight compared to existing design, cost of the crankshaft, without changing connecting rod or engine block.
