Course Content (Themes, Concepts, Issues and Skills)

While studying the four stroke cycle", students will be able to classify engines based on cylinder number, configuration and/or valve train design. Students will trace engine lubrication and cooling systems as well as understand the causes of wear and part failure. Students will also become familiar with the concepts of volumetric efficiency, horsepower and torque. In addition, students continue to develop and practice skills related to hazardous waste disposal, and avoidance of potential shop hazards.

  • Utilize proper safety procedures
  • Identify cylinder and valve train configuration
  • Use hand tools properly
  • Utilize appropriate industry protocol
  • Grind valves and valve seats
  • Inspect", measure and install piston rings
  • Adjust valve train
  • Install distributor
  • Locate and use proper seals and gaskets in reassembly procedure
  • Visually inspect engine components
  • Use precision measuring tools: micrometer", dial bore indicator, plastigauge
  • Evaluate condition of reciprocating and rotating parts
  • Clean engine machined gasket surfaces
  • Assess condition of oil and coolant pumps
  • Complete accurate measurements using compression gauge
  • Perform cylinder leakage test
  • Perform oil pressure test and determine necessary action

Students perform engine analysis/testing, using plastigage, oil pressure gauges, 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 €œA-F€ grades with direct feedback delivered within 1 week.

Communication
Hours: 2

1. Communicate effectively with employers, customers and co-workers.
2.  Develop and implement strategies and processes to solve internal engine repair problems.
 

Students continue their practice from previous courses by working in teams to communicate with staff to check out tools, school cars, and have repair orders written for lab projects.

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

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

Human Relations
Hours: 15

1. Perform internal engine repair to the highest professional and ethical standards.
 

Students build on previous course work in human relations to continue the practice of human relations introduced through class discussions and homework.
Students work in teams to complete assigned lab projects.  Team work is focused on working in a diverse cultural environment, being sensitive to Others needs and diffusing difficult situations in a calm and respectful manner. 
Students work with lab partners, staff members, and their instructor to bring customer/school cars in /out of the shop for class lab projects.

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