This lesson is designed for entry level students to understand the four strokes of an engine and how a 4 stroke engine functions.

Students will learn to diagnose and repair ignition problems. Students will learn that there are some common problems to look for, such as a loose spark plug wire or an arcing spark plug wire, when attempting this service.

This in an introduction to what is Bore and Stroke; the meaning of short and long, larger and small; and to introduce the meaning of over square and under square. (Note: This is not about calculating the volume of a cylinder using math.)

This is an introductory lesson into the construction, operation and the diagnostic techniques used for the common automobile catalytic converter.

Introduce students to the operational theory and practical service techniques of the automotive starting system. Students will be introduced to the specialized diagnostic and service equipment required to perform these tasks. Students will also understand how to interpret customer complaints as they relate to this system.

Introduce students to the operational theory and practical service techniques of the automotive charging system. Students will be introduced to the specialized diagnostic and service equipment required to perform these tasks. Students will also understand how to interpret customer complaints as they relate to this system.

Upon completion of this lesson, students will be able to demonstrate knowledge of the four stroke cycle and the ingredients to internal combustion.  Students will identify events taking place within the cycle using a projected animation and actual cutaway engines.

Upon completion of this session, students will be able to explain how the fuel/air charge is created, how it enters the cylinder and how it is used in the engine.  They will also be able to identify major carburetor components and explain the pressure/vacuum correlation to carburetor function. The session will conclude with students performing adjustments on a small engine carburetor using colored water as fuel and on an actual running automobile engine using a gas analyzer.

Upon completion of this session, students will be able to identify air movement events in relationship with mechanical events within a four stroke cycle of a single cylinder internal combustion engine. 

Students will be able to determine where an engine is in its cycle by looking at mechanical drawings and cutaway engines and explain which event is taking place at that time.

Students will understand the minimum compression needs for internal combustion with gasoline and acceptable cylinder compression variances.

Students will perform cranking compression tests and cylinder leakage tests to determine the cause of failure.

Upon completion of this session, students will have an understanding of how a primary ignition signal is generated and be able to diagnose the lack of a primary ignition signal using a voltmeter and an oscilloscope.  They will also understand how an ignition coil functions and be able to diagnose a failed ignition coil using an ohm meter and an ignition scope.

This lesson will explain the steps to remove and replace an engine valve from an overhead valve engine.
