RE: EVOC 501, WR2 Topics & Tasks
The purpose of the WR2 assignment was to prepare a list of specific topics
and a list of related specific tasks appropriate for the course I teach in Automotive
Engine Performance. The following six
criteria were specified:
1. Comply with all of the General Criteria for Written Reports.
2. Emulate the Fred Fudrucker example for FORMAT, but include my own CONTENT.
3. Write a brief SYNOPSIS of the description of the "occupation" that my course is intended to prepare people for, as that occupation is described in the Dictionary of Occupational Titles (DOT) and indicate whether or not I believe the information in the DOT is accurate.
4. List and briefly describe FIVE TOPICS appropriate for the course I teach.
5. On a separate list, describe an appropriate SPECIFIC TASK for EACH of the five topics described. These tasks should be written in terms that indicate exactly what it is that students are expected to be able to DO and how student competency will be measured.
6. Include a deliberate and obvious error somewhere in the report. Describe this error on a separate sheet of paper that will be given to the instructor (only) along with the copy of the report that is submitted for grading.
The following sources of information were used relative to this assignment:
1. Fournier, Phil – From my own professional experience
2. Dictionary of Occupational Titles (Vocational rehab link on DOL website) http://www.vocrehab.com/title_search_1.htm
James D. – Automotive Engine Performance, Prentice Hall publishing,
I believe that the attached report meets all six of above listed criteria. I have (or at least, will have) prepared and distributed a copy of this memo and the attached Topics and Tasks, for all of the other class members. I respectfully request full credit: one point for meeting each of the above listed criteria.
Topics and Tasks for a course in Automotive Engine Performance
By Phil Fournier
Dictionary of Occupational Titles Description:
(Tune-up Mechanic 620.281-066)
Tunes automotive vehicle engines to ensure efficient operation: Removes spark plugs, using socket wrench, and tests them, using spark-plug tester. Cleans electrodes in sandblasting machine, sets spark gap with feeler gauge, and replaces or installs new plugs. Inspects distributor breaker points for wear and pits, using feeler gauge, and replaces or resets points. Observes ignition timing, using timing light, and adjusts timing, using handtools. Adjusts carburetor needle setting, using handtools, and verifies adjustment, using instruments, such as fuel analyzer, vacuum gauge, oscilloscope, and tachometer. Sets valve tappets, using feeler gauge or dial indicator. Replaces defective coils, condensers, and electrical connection. Removes and cleans carburetor and fuel pump. Examines battery and connections and electrical charging and starting circuit. Adjusts, and repairs fan belt, and fuel and water pumps.
Please Note: The above, wordy job description is hopelessly outdated, starting with the job title. Indeed, even for a document published in 1991, it is outdated, listing technology that went out of use 30 years ago. Many of today’s technicians have never worked on a carburetor (last model in 1990) and distributor points were discontinued in 1974. The title in common use today is “drivability technician”.
Topics for a course in Engine Performance:
1. Information about base engine systems.
2. Information about starting and charging systems.
3. Information about ignition systems.
4. Information about fuel systems.
5. Information about computer control systems.
Tasks for a course in Engine Performance:
1. Given an illustration of engine vacuum gauge readings, each student will correctly match the vacuum gauge reading with the appropriate engine condition or malfunction. (measured by fill-in-the-blank test question).
2. Using a battery load tester, each student will demonstrate correct technique to test a battery’s state of charge. (measured by a performance evaluation).
3. Using an ignition system oscilloscope, each student will demonstrate their ability to display a parade pattern and a raster pattern on the oscilloscope. (measured by a performance evaluation).
4. Each student will write out the names and a short description of the three types of fuel delivery systems on modern automobiles. (measured by a short essay test question).
5. Each student will learn the operation of a closed loop system. (measured by a short essay test question).
