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 welldesigned 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.
