l l l l l




PURPOSE AND PERSPECTIVE OF THE CHAPTER L L L L L




The purpose of this chapter is to introduce students to the basic construction and operation of an internal
l l l l l l l l l l l l l l l l l




combustion engine. It describes the many engine components and how to identify the various pieces. Also
l l l l l l l l l l l l l l l l




explained are the different engine classifications along with the different systems and how they work together
l l l l l l l l l l l l l l l l




to keep the engine operating effectively.
l l l l l l




CHAPTER OBJECTIVES L




Upon completion of this chapter, the student should be able to:
l l l l l l l l l l




• Explain the principles of internal combustion engine operation.
l l l l l l l




• Identifyinternal combustion engine parts by name.
l l l l l l




• Explain various engine classifications and systems.

CHAPTER OUTLINE L




• In a simple one-cylinder engine, the reciprocating (up-and-down) motion of the piston is changed to
l l l l l l l l l l l l l l




usable rotary motion by the connecting rod and crankshaft. A flywheel gives momentum to the
l l l l l l l l l l l l l l l




crankshaft between power strokes. Valves control the engine’s intake and exhaust. (PPT Slide 4)
l l l l l l l l l l l l l l




• During one four-stroke cycle, the intake, compression, power, and exhaust strokes are completed. This
l l l l l l l l l l l l l




action takes 720°, or two crankshaft revolutions. (PPT Slide 5)
