DESCRIPTION:

Fundamentals There comes a time when work stops and the mechanic becomes abstracted, distant from the task at hand. Something about the machine does not conform to the picture in the mechanic’s mind. Images flash by until he or she finds one that most closely conforms to actual conditions. Once that is done, repairs can begin. Constructing visual images is what mechanics do; the other stuff is mere wrench-twisting. This chapter provides grist for these mental images.

• Because the material must be conveyed in words, it tends to be abstract. But once you can picture how these engines work, you will have made the first step in the journey to becoming a real mechanic.
• Spark-ignition engines operate in a cycle consisting of four events: intake, compression, expansion (or power), and exhaust. A fresh charge of air and fuel is inducted into the cylinder, which then is compressed by the piston and ignited by the spark plug.
• The pressure created by combustion reacts against the piston to generate torque on the crankshaft. The spent gases then exhaust into the atmosphere. Four-stroke-cycle engines require four up and down strokes of the piston, or two full crankshaft revolutions, to complete the cycle.
• Two-stroke-cycle engines telescope events into two strokes or one crankshaft revolution. For convenience we abbreviate the terms to four-cycle or four-stroke, and two-cycle or two-stroke.
