CCOG for AM 182 Fall 2024


Course Number:
AM 182
Course Title:
Engine Performance II
Credit Hours:
4
Lecture Hours:
0
Lecture/Lab Hours:
80
Lab Hours:
0

Course Description

Reinforces the use of automotive scan tools, lab scopes, and electronic test equipment. Reviews the operation and testing of electronic ignition systems. Introduces intermediate fuel delivery and emissions control system concepts and testing. This is the second course in a three-course sequence. Audit available.

Addendum to Course Description

This course is designed for students with no previous industry experience. Students will develop the skills, knowledge and attitudes necessary to perform, with limited supervision, the appropriate procedures involved in engine performance diagnosis and adjustments on cars, pickups and vans. This course will prepare students for the Auto Shop Lab capstone courses which provide the opportunity to practice learned skills on customer and school controlled vehicles in a “working shop” setting. This will begin the skill level necessary for employment at an apprentice level.

The course material will be presented in a lecture/laboratory format and include videos, handouts and hands-on lab experience in the shop. Students are required to read assigned materials, take notes, complete homework assignments and research information in service manuals and with electronic service information systems.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Perform engine performance inspection, maintenance, diagnosis, and repairs relating to engine performance systems at an intermediate level.
  • Access and utilize repair information in a rapidly changing technology.
  • 欧洲杯决赛竞猜app_欧洲杯足球网-投注|官网 and implement strategies and processes to solve engine performance problems.
  • Perform diagnosis and repair of fuel delivery systems to professional and ethical standards.
  • Demonstrate intermediate-level knowledge of fuel delivery and emission control systems.
  • Communicate professionally with employers, customers, and co-workers using industry standard language and following industry standard protocols.

Outcome Assessment Strategies

  • Students will demonstrate effective work with fellow technicians in the following ways:
    • Attendance requirements include penalties for excessive days missed and late arrivals.
    • Lecture participation requirements include bringing textbooks to class, being prepared to take notes and remaining attentive in class.
    • Laboratory participation requirements include demonstrating good craftsmanship, using time wisely, treating equipment properly, using procedures properly, demonstrating acquired skills and correct use of tools.
    • Demonstrate preparedness for ASE testing by achieving a passing score on all written exams and completing homework assignments.
    • Demonstrate understanding of course material through passing scores on lab activities.

Computation
Hours: 15

  • Perform engine performance inspection, maintenance, diagnosis and repairs relating to engine performance systems at an intermediate level.
  • 欧洲杯决赛竞猜app_欧洲杯足球网-投注|官网 and implement strategies and processes to solve engine performance problems.

Students measure engine performance (emissions system) components using voltmeters, lab scopes, gas analyzers and scan tools, and compare results (percentages, ppm, volts, pulse width, etc…) with manufactures/industry specifications.  Apply Ohm’s Law theory to electrical system circuit analysis.

Students perform engine performance (emissions system) analysis/testing, using voltmeters, lab scopes, gas analyzers, etc…, and compare readings to manufacturers/industry specifications.

Assessment:  Feedback is immediate, direct and pass/no pass for classroom or lab assessed activities.  Homework and exams are “A-F” grades with direct feedback delivered within 1 week. 

Communication
Hours: 4

Communicate professionally with employers, customers, and co-workers using industry standard language and following industry standard protocols.

Students work in teams to communicate with staff to check out tools, school cars, and have repair orders written for lab projects.

Students verbally explain to instructor methods and reasoning behind various types of testing procedures performed as hands on lab activities.


Students present a verbal report to the class on a subject of their choice related to current industry technical advances, innovations, safety standards, and/or diagnostic or trouble shooting procedures related to emission systems.
