During the last several years, significant efforts have been directed toward the development of ultra-clean, gasoline-powered vehicles in the automotive industry. With the coming of increasingly stringent emissions legislation, this development is more critical now than ever before. This has led to an increase in the technical information available. Recent Developments in Ultra-Clean Gasoline-Powered Vehicles provides the reader with technical information including a description of fundamental processes, insight on technical issues, key trends, and future R & D directions. This book is organized into 14 chapters and contains 53 technical papers. Each chapter begins with an overview of the chapter topic authored by an expert in the subject field, followed by the related SAE technical papers.
