availability analysis of Crank Case manufacturing in a two wheeler automobile industry
Applied Mathematical Modelling, 2010Co-Authors: Savita Garg, Jai Singh, D V SinghAbstract:Abstract The paper describes the availability of Crank-Case manufacturing system in an automobile industry. The units discussed here fail either directly from normal working state or indirectly through partial failure state. The machines are subjected to both preventive and corrective maintenance. Failure and repair times of the units are independent. The problem is formulated using probability consideration and supplementary variable technique. The system of equations governing the working of system consists of ordinary as well as partial differential equations. Lagrange method and Runge–Kutta method is used to solve partial differential equation and ordinary differential equation respectively. The study reveals that successful program of preventive and routine maintenance will reduce equipment failures, extend the life of the equipment, and increase the system availability to considerable margin.

experimental investigations of ethanol blended biodiesel fuel on automotive diesel engine performance emission and durability characteristics
Renewable Energy, 2019Co-Authors: Senthil Kumar Kandasamy, Arun Saco Selvaraj, Thundil Karuppa Raj RajagopalAbstract:Abstract 500 h durability, performance and emission tests are conducted on a single cylinder high speed automotive diesel engine for the ethanol blended biodiesel fuel. Esterified cotton seed methyl ester of 5% by volume is mixed with 95% neat diesel to obtain the base biodiesel fuel (B5). The base fuel is mixed with 20% pure ethanol to derive the ethanol blended biodiesel fuel (B5E20). The parameters like blow-by, Crank Case pressure and lubricating oil consumption are experimentally investigated along with performance and emission characteristics for both the test fuelled engines. The result of these tests showed a significant loss in maximum brake power and maximum brake torque at the end of 500 h durability run when the engine is fuelled with B5E20. The lubricating oil consumption and positive Crank pressure of B5E20 fuelled engine is comparatively higher than B5 fuelled engine during the durability trials. Reduction in smoke and CO emissions are noticed for B5E20 fuel over the entire range of speed whereas NOX and unburned hydro carbon emissions get decreased at lower to medium speed range and increases thereafter. As expected, all the engine emissions increase after 500 h of durability run for both the fuels.
