Abstract
In this work, an effort has been designed to raise the reliability of engine using Al-Sic composites with other alternatively materials for the engine valve guides. Aluminum matrix composites have found the most suitable inside automotive, aerospace and aircraft industries and contain the greatest promise for future year’s growth. The finite element analysis of the Al-Sic composite with Titanium alloy (Ti-834), Copper Nickel Silicon alloys (CuNi3Si), and aluminum bronze alloy as an alternative material for engine valve guide was done using Ansys 13.0 software. The stress analysis of engine valve guide under the different pressure and temperature is considered, the pressure is taken as from 10 MPa to 100 MPa with different temperatures varying from 600℃ to 650℃. The temperature, principal stress and principal strain distribution on the entire surface area of the engine valve guide were obtained. The stresses were observed to be well below the permitted stress for all the materials but the Al-Sic composites found the most suitable one. Valve guide is modeled in pro-engineer software and analysis is carried out in Ansys 13.0. The deformations and stresses induced due to structural and thermal loading is illustrated and discussed.

In reaction to increasing worldwide competition and developing concern for environment, the auto manufactur-. Yasar Deger [13] Noticed that the efficiency of the interdisciplinary multi physics analyses and the quality of their results are highly dependent on the probability to access the knowledge and expertise of company specialists in finite element applications, materials sciences and fluid dynamic An example of such a close cooperation at Sulzer Innotec was the numerical analysis of the thermo mechanical stresses in the exhaust manifold of a diesel engine with active water cooling system. P. Gudim et al [19] in the year 2009 suggested a CAD model of a damaged internal combustion engine piston and by using the finite element analysis tool ANSYS to perform a linear static and a coupled thermal-structural analysis of the component. Such materials allow reducing the difference of the coefficient of thermal expansion for cooling and heating and as a result it increases the dimensional stability of the piston
