Stress Analysis in Cylinder Liner for Tata Indica V2 Diesel Engine

The cylinder liner is one of the most important components in an internal combustion engine that possesses the intricate structural arrangements coupled with complex patterns of various operational loads. Due to the high combustion temperature produced during engine operation, the inner periphery of the cylinder liner has every chance of large stress accumulation. As a result, the surface wears off and there will be irregularities in the cylinder surface which in turn affects the engine's performance. The function of a liner is to provide effective heat transfer and generate minimum stress within so that the engine can be highly durable and used in the long run. Thus it is important to optimize the thickness of the cylinder liner and cylinder liner material combination. The current study focuses on the influence of liner thickness and material combination on temperature distribution and stress conditions in the cylinder liner assembly. A 3D model of a Tata Indica V2 diesel engine was modeled and investigated the influence of parameters such as the thickness of liner and material combination on temperature distribution and stress conditions using ANSYS 14.0 under steady-state condition. The cylinder liner material and its thickness were optimized to obtain optimize heat transfer rate and to minimize the thermal stresses. The results showed that there is a minimum stress accumulation at the inner periphery of the cylinder liner when the liner thickness is 2.5 mm. The highest temperature was observed for the A383-Ductile iron combination which is 189.330C. It is also observed that liner and cylinder block made of aluminium alloys have minimum thermal stress and are least for the A356-A390 combination (36.78 MPa). Hence it can be concluded that Aluminium alloys with high thermal resistance are most suitable for liner material. Citation: Ajeesh A S, Robin David, Thoufeek N A, Vinay V A, Mohammed Arif.
