Course outline and Syllabus

TEXT

 Text at the time of Class wiil be known

Presents logical diagnostic paths to identify vehicle HC-CO failure areas.

Teaches a progression of failure detection from most likely to more complex cause. Emphasizes use of infrared analyzer and manufacturer's specified adjustments.

** This is not an entry level class, please bring a pencil to class! **

Lecture four (4) hours per week for 8 weeks. 

Course Purpose:

AUT 215 is a one semester course designed to provide practicing automotive

technicians with specialized training in the sampling and analysis of vehicle

emissions. The student will become acquainted with State and Federal laws

pertaining to vehicle exhaust emissions from mobile sources. The student will be instructed in the use of the test equipment designed to measure varying concentrations of different exhaust gases. Through the efficient use of a logical and systematic diagnostic procedure, the student should be able to determine the operating conditions of the engine and related emission control devices and make any needed repairs or adjustments.

Teaching Procedures:

The course will be taught through a series of planned lectures with films, pictures, slides and handouts when necessary to illustrate practical application of theory to actual operation of automotive emission systems. Selected demonstrations will be used when necessary to show the student how faulty emission systems effect automotive operating efficiency, the student will be taught proper test equipment use for trouble shooting the emission system, how to hook up the equipment and how to read and the information gained through it's use.

 

Entry Level Competencies:

Ability to read, write, and speak the English Language.

Course Objectives/Educational Outcome:
        1. To describe the most significant features of State and Federal laws regarding vehicle exhaust emissions and their control.
        2. To locate and identify the various emission control devices used by automotive manufacturers.
        3. To explain the purpose of each emission control device.
        4. To explain the causes and effect relationship of combustion efficiency and exhaust emissions.
        5. To demonstrate the efficient use and operation of a gas infrared exhaust analyzer.
        6. To identify and explain the proper procedures required to diagnose and repair a vehicle with excessive emissions.
        7. To list general problem areas that can contribute to excessive HC emissions.
        8. To list general problem areas that can contribute to excessive CO emissions.

Major Elements of Content (NATEF):
        1. Positive crankcase ventilation (PVC) system.
        2. Spark timing control system.
        3. Idle speed control system.
        4. Exhaust gas recirculation (EGR) system.
        5. Exhaust gas treatment. Air injection reaction (AIR); catalytic converter.
        6. Inlet air temperature control system.
        7. Intake manifold heat control system.
        8. Fuel vapor control system.

 

Optional Elements of Content:

None.
