Abstract

nRecent analysis that has given performance on the basis of thermal analysis of thermostat valve. Play an important role in automobile Cooling system. And its performance can change according to its different temperature conditions. Thermostat valve has been extensively study with the primary direction it’s Bring Down engine temperature and upgrade performance of engine. Thermostat valve play an important role in automobile cooling system for durable the engine temperature in working condition. In this spot we use computer model analysis and simulation to examine thermal changes in thermostat valve using two different apparatus/material for analysis of thermostat Valve thermal analysis and simulation display the thermal changes in thermostat valve and tell how it will effect on cooling system. In automobile engine, there was a cooling system which work as cooling to the all vehicle. In such system the thermostat valve is operating all the cooling system with help of wax which is present in charge cylinder. The wax having something different property which work as at time of high temperature as fluid and at time of low temperature as solid structure in cooling system. The thermostat is 10/heart of cooling system it’s because of the without thermostat the system will not work properly. The engine is a reciprocating device which is work on heat of the fuel crate heat which is control by the cooling system. There was two different type of cooling system one is water cooling system another one is air cooling system. Most probably for the giant engine the water cooling system is used which is give power lost to engine but its profitable for the engine life. Air cooling system is maintenance free which is profitable but its work on small size of engine just like two wheeler engine.n

Abstract

nAnalysis of thermal changes of piston, in an automobile an engine is heart of automobile likely in engine that actual mean to piston, who having very important role in the engine, Piston is always subjected to various loads mainly subjected to thermal and mechanical stresses. The role of piston is very clear i.e. transmit or the guide the piston rod which is connected to crankshaft while transmitting piston has to carry out gases pressure forces, thermal stresses too. Piston is the reciprocating part of engine which converts chemical energy into thermal energy then mechanical energy. Therefore piston is always carrying thermo-mechanical load on the piston, piston fails occurs due to fatigue failure which occurs due to cyclic mechanical and thermal loading on the piston. To increase the life of piston and to increase sustainability in thermo-mechanical load wide range of research are going on to modify the design, thermal properties by changing various material alloy, method of, manufacturing are also changed. This follows a conventional technique for calculating critical dimensional values using empirical equations and material constants derived from prior data. Using solid modelling software such as CATIA v5 and SOLIDWORKS, a three-dimensional model of a piston is created, and meshing is done or can be built using a finite element model. Further, a finite element model can made by ANSYS which gives help for actual report of analysis. Thermal flux and temperature distribution are studied in thermal analysis by applying various temperatures to the piston’s surface.n

Abstract

nThis paper includes the design and thermal analysis of an uncoated & coated IC engine piston made of aluminium-silicon alloy. Thermal analysis is performed on pistons cylinder comprised of aluminium alloys covered with artistic material (Y2O3ZrO2). The bonding is done by unique material (Ni-Cr-Al). Designing is done by appropriate machine design approach and the piston dimensions are determined by finite element analysis (FEA). FEA was performed using ANSYS. The coating effects on the thermal behaviour of the pistons are also investigated.n
