This book combines the subjects of carburation and fuel injection. The reader is taken from the basic operation of the carburettor and fuelling theory to the most sophisticated electronically controlled fuel injection in use today. The text covers the common carburettor 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 a whole section on fault finding.
