Enclosed Power Point Presentation 3. Laboratory Introduction I. Introduction : The gasoline engine consists of many parts that function together as a smooth power team. It is important to be able to identify these parts and explain how they fit and work together. Students are to disassemble a typical four-stroke cycle engine, study the basic parts, and then prepare to check for wear and reassembly of the engine in the two laboratories that follow this one. Before starting to disassemble the engine, make sure it is full of oil, then run the engine for a minute or two. Safety glasses must be worn! Remember, the speed of work done in the next three labs is not important! What is important is a careful, workmanlike approach to the job. At the beginning of this lab the instructor will properly disassemble an engine that will be similar to yours. It is your job to pay close attention to the techniques used, as well as to take detailed notes for your own purposes. Following the instructors disassembly, you and a partner will be charged with the disassembly of an engine that will be assigned to you. The following disassembly procedure will take you step-by-step through the process. The procedure is generic in that it works with a number of different types of engines that are present in the lab. Reminders have been given to you for each step, and will let you know when engine differentiation is important. It important that you remember that this is not a race! Careful attention should be given to each step....
