It is an important part of any engine system and comprised of a stem and a head. Exhaust valve is precision engine components used to open to permit the burned gases to exhaust from cylinders. In this thesis, methane fluid is mixed with ethane are calculated for their combination properties. The nano particle for volume fraction 0.2, 0.4, 0.6 & 0.8. Theoretical calculations are done determine the properties for nano fluids and those properties are used as inputs for analysis. In this thesis, a finite-element method is used for modeling the thermal analysis of an exhaust valve. The temperature distribution and resultant thermal stresses are evaluated. Detailed analyses are performed to estimate the boundary conditions of an internal combustion engine. In this thesis, CREO parametric is employed for modeling and ANSYS is used for analysis of the exhaust valve. CFD analysis to determine the pressure drop, heat transfer coefficient, mass flow rate and heat transfer rate for mixed fluids (methane and ethane) at different volume fractions. 1. INTRODUCTION TO IC ENGINE VALVE 1.1. Valves Train Components for Internal Combustions Engines, which include 1. Inlet and Exhaust Valves 2. Valve Guides 3. Tappets 4. Camshafts What does an engine do?  It generates the power required for moving the vehicle or any other specific purpose.  It converts the energy contained in fuel to useful mechanical energy, by burning the fuel inside a combustion chamber.  An engine contains number of parts like Valves and other Valve train components, Piston, camshaft, Connecting rod, Cylinder block, Cylinder head etc., from which REVL supplying some of the valve train components to engine manufacturers. 1.2. Types of Engines 1.2.1. From the basic concept there are 2 major types of engine. Which are subdivided further based on their working principle. 1. Internal Combustion Engines (IC Engines) a) 2 Stroke Engines b) 4 Stroke Engines 2. External combustion Engines (EC Engines) a) Steam engines (E.g. Locomotives) b) Turbine engines (E.g. Aircraft) 1.2.2. Based on the Fuel Used, IC Engines can be classified as follows. 1. Diesel Engines (CI Engines) a) DI / IDI / CRDI b) NA / Turbo Charged 2. Petrol Engines (SI Engines) a) Carburetor Engines b) SPFI / MPFI Engines 3. Gas Engines a) LPG b) CNG 1.2.3. Based on the Application, IC Engines can be classified as follows 1. Automotive Engines a) On road Vehicles b) Off road Vehicles c) Marine Applications d) Racing Vehicles 2. Stationary Engines a) Generators b) Power Plants
