- There is a giant two step migration in Indian automotive industry from Bharat stage IV to Bharat stage VI emission norms. This emission regulatory migration demands substantial engineering efforts to design, develop and validate engine, engine components and complete exhaust after treatment system. In this context, cylinder bore distortion plays a vital role on engine blow by, oil consumption and its effect on DPF ash loading. For BSVI engines, overall thermal loading is increased and that causing more mechanical & thermal stresses over the engine and subsequent components. Increased engine bore distortion have ill effects on the engine and after treatment devices. Reduction of bore distortion help piston rings to confirm with bore, which results into low oil passing through rings towards the combustion chambers which finally results into low oil burn off in combustion chamber. In the present work, the study was conducted to reduce cylinder bore distortion by various design of experiments which includes different torque plate honing with changing head bolt torque values, use of conditioned gasket and repeatability of bolt uses on the bore distortion values. Study resulted into improvement of bore distortion around 30 % from baseline.
