Abstract
Perkins is a name with a worldwide reputation for diesel engines, won from more than 70 years manufacturing at its Peterborough, UK, factory site. Now part of the Caterpillar organisation, it is winning even more acclaim for the quality of its engine testing, backed by Six Sigma quality credentials. Motor manufacturers from around the world are coming to Perkins for objective, ‘benchmark’ measurements of their products, against stringent current operating and/or legislative criteria.
