This volume takes you from the basic operation of the carburetor and fuelling theory to the most sophisticated electronically controlled fuel injection in use today. Divided into two main parts, theory and practical tasks, detailed text covers the common carburetor and injection system types (including older designs), plus their supporting components such as air filters, fuel pumps and sensors. Practical advice covers overhaul, set up and the use of diagnostic equipment, plus an entire section on fault finding.
