Introduction to Marine Engineering

Section 6.4 Major Components of a Diesel Engine

To understand how diesel engines work, you will need familiarity with the major components of the engine and how they work together. Figure 6.4.1 illustrates a medium-sized, four-stroke, turbocharged, diesel engine with inlet ports and exhaust valves. Figure 6.4.2 provides a cross section of a similarly sized V-type diesel engine which might be used for marine propulsion.
