“…Most failures occurring in turbochargers emerge on the turbine housing which is exposed to the high temperatures of the exhaust gases. 8,9 On the other hand, the compressor housing that supplies the compressed air to the combustion chamber is associated with low-temperature conditions. Figure 2 shows typical crack locations on the turbine housing which occur because of the engine thermal shock test.…”

In order to predict the thermomechanical failure of the turbine housing, it is essential to consider temperature-dependent inelastic materials undergoing thermal cyclic loads and to obtain the transient temperature distributions. This paper presents the analysis methods to calculate the thermal stresses and the plastic strain ranges for prediction of the fatigue life. The presented work is based on the engine motoring mode test that is commonly used for accelerated engine endurance tests. The results showed that the localized critical regions coincided well with the crack locations identified on the basis of a thermal shock test. The plastic strain values were predicted to lie within the range 0.216–0.396% corresponding to a range of 628–1450 cycles for 1600 target cycles.

Each after treatment system design should be done in such a way that considering the complete system objectives. Energy efficient exhaust system development requires minimum fuel consumption and maximum utilization of exhaust energy for reduction of the exhaust emissions and also for effective waste energy recovery system such as in turbocharger, heat pipe etc. from C.I. engine. Traditional manifold optimization has been based on tests on Exhaust system. This trial & error method can be effective but is very expensive & time consuming. Beside this method cannot provide any information about the actual flow structure inside the system. This vital information can be obtained using 3-D CFD analysis. The design engineers can study the flow structures & understand whether a particular system performs correctly or not.
