Introduction

The fuel injected into the combustion chamber must be mixed thoroughly with

the compressed air and distributed as evenly as possible throughout the

chamber if the engine is to function at maximum efficiency and exhibit

maximum driveability.

The well-designed diesel engine uses a combustion

chamber that is designed for the engine's intended usage.

This task illustrates the function of a diesel fuel system.

It will

describe the principles and construction for the following components of

this system: injection systems, fuel supply pumps, governors, timing

devices, and combustion chambers. The combustion chambers described in the

following paragraphs are the most common, and cover virtually all of the

designs used in current automotive practice.
