Surface improvements [india] limited, in association with nagel, germany and nagel, india have been able to successfully establish plateau honing parameters in a wide range of ic engine cylinders, mostly cast iron. This is particularly important in view of the strict pollution control norms in automobiles. Appropriate use of conventional or diamond rough honing followed by the right grades of base and plateau honing combination has yielded excellent results. This has brought a new level of achievement in critical surface finish and geometry parameters, so important to meet euro norms. It si well known that achieving the correct grade of plateau honing brings in the twin benefits of both vastly reduced oil consumption and more importantly vastly reduced harmful emission. This makes conformity with euro norms and easier tasks.
