Abstract
Exhaust system of car is studied by thermal analysis. Temperature is uniformly distributed from $22{^{\circ}C}$ to $200{^{\circ}C}$ on exhaust system due to heat transfer. The largest deformation of 2.6919mm is shown at the left end of muffler. The inner face combined with exhaust manifold is applied by the largest thermal equivalent stress of 914.61MPa. After the elapsed time of 360 second, the end of muffler is shown to have the largest deformation of 2.5538mm and the bolt combined with this muffler is applied by the largest equivalent stress of 887.79MPa. By reinforcing material at the end of muffler or fastened bolt shown with highest thermal deformation or stress, the durability at this system can be improved.
