Diesel Engine Cylinder Liner Distortion Analysis

Abstract

Internal Combustion Engine is the heart of any automobile. Hence its performance directly affects the performance of automobile. To measure the performance of engine is an important aspect. When the engine is in working, due to high combustion gas pressure and temperature heat is generated inside the cylinder that heat is transferred to the cylinder wall, crank case oil and piston. In this report, the distortion of cylinder bore has been analyzed. As for the tri biological system, the ideal conditions for the function and durability, shape of liner should be circular as possible. The distortion of the cylinder liners of internal combustion engines has significant effect on engine operation .It can affect the oil consumption, the blow-by, the wear behavior and due to friction, fuel consumption. In order to achieve future requirements regarding exhaust emissions and fuel consumption the development of low distortion engine blocks will play significant role. The calculation of engine heat transfer is difficult, due to the periodic air and fuel flow and the complex geometry of the engine. We rely primarily on experimental results. With recent advances in computational fluid dynamics, computation of engine heat transfer is becoming more possible
