Cylinder bore deformation plays an important role between piston and cylinder bore. The cylinder bore deformation may happen due to manufacturing process tolerances, assembly loading, thermal loading and dynamic gas loading. It has significant impact on the friction, fuel economy, lubricant oil consumption, reduction in power, increase in emissions, uneven power generation in different cylinders etc. This work proposes FEA analysis procedure that could be used to evaluate the cylinder bore distortion due to assembly (clamping) load of cylinder head bolts. Cylinder bore deformation due to head bolt clamp loading is predicted using FEA analysis package MSC NASTRAN for 3 cylinder inline Diesel engine. The effect of various parameters like effect of increase in pretension force on amount of bore deformation are studied. The predicted results are compared with previous experimental results and fair agreement have been observed.
