Today's Technician: Automotive Engine Performance

This second edition has been updated throughout to provide the theory and hands-on experience in engine performance. Students and technicians will find coverage of engine design and operations, ignition systems, emission controls, and OBDII systems in the Classroom Manual. Located in the Shop Manual at the end of each chapter are two new features: Job Sheets and ASE Challenge questions, providing a format for students to perform the tasks covered in each chapter, and questions reflecting the actual content of ASE certification tests.
