This comprehensive training and education package focuses on the major engine systems affecting engine performance and driveability, with topics ranging from engine basics to fuel, ignition, and OBD-II systems. Various manufacturers' vehicle systems are represented to illustrate the similarities and differences technicians will encounter today. Current and thoroughly-updated system information and diagnostic strategies in this edition, added to help students keep pace with emerging technologies, include: a new systematic approach to diagnosing problems; updated scanner information; new engine technology, including the throttle actuator control system; new magneto resistive sensors; recent emission inspection requirements and mandates specifically regarding OBD II; expanded discussion of fuel cell technology; expanded discussion of the operation of hybrid vehicles. Like other books in the Today's Technician series, the Classroom Manual covers the subject fundamentals, discussing theory and operation of each engine system. The Shop Manual provides the service and diagnostic "how to" component, with hands-on exercises that reinforce concepts learned in the Classroom Manual. Restructured Job Sheets in the Shop Manual provide a format for students to perform the tasks covered in each chapter.Vidler, Douglas is the author of 'Today's Technican Automotive Engine Performance', published 2003 under ISBN 9780766848641 and ISBN 0766848647.
