Final Exam Information

Intro to Engine Performance Home 

The ASE style Final Exam will be held on Tuesday March 18th at 1:00 P.M.
Alternate final time and/or date may be arranged in advance.  You may also take the Final Exam at 2:30 P.M. if you have any conflicting final tests for any other LBCC class.

You can use notes that you have created (and your assignment #8) to use while you are taking the final.

What you need to know for the Final...

Understand how to use the Solus Pro –
... Basic function of the Y and N button
... What the Troubleshooter does
..  What a PID is and the difference between an input (sensor) and output (actuator) signal
... What the DLC is – how many pins – where is it?  Why is it there?
... What an OBD II monitor is.  What happens to it when codes are erased.  What has to happen to get a monitor to “run” 
... What a custom data list is and why you would want to create one.
... What a scan tool is used for other than engine performance
... Difference between the OBD room and OEM room
... What turns ON the check engine light and what happens when a code is set
Basic no-start diagnosis
...  Difference between too lean and too rich, how to tell? 
...  what tests for too rich causing a no-start
...  what tests for too lean causing a no-start
... What causes too rich?
... What causes too lean?
...  What to check if there is Spark at the tester and no start with Propane added?
...  What do you check for if there is no Spark at the tester?
...  What does adding propane while cranking tell you?
...  How can you tell if the fuel pump is running?
...  How can you tell if the injectors are turning on and off
           (2 different ways to test injectors)
... How can a weak battery (under 10 volts cranking) cause low compression
... How can a weak battery (under 10 volts cranking) cause a lean fuel mixture during cranking
... How to check for compression using vacuum and does no vacuum mean no compression?

What do the basic sensors do?
... MAP sensor
... MAF sensor  (what happens if air/vauum leaks after the MAF sensor)
... TPS sensor
... CKP sensor
... CMP sensor
... What can cause an oil soaked air filter?
... When is manifold vacuum high?  When is it low?
... What does it mean when a vacuume gauge bounces rapidly.

Basic four stroke theory.
...What valves are open or closed when the piston is at the top dead center and bottom dead center of each of the 4 strokes.

... What opens the valves?
... What closes the valves?
... How will poor compression in one cylinder affect the way an engine runs?
... How will poor compression in all cylinders affect the way an engine runs?
... What causes poor compression?
... What do the piston rings do?
... What does the crankshaft do?

... What does the timing belt or timing chain do?
... What is the relationship in speed between the crankshaft and the camshaft?
... What happens to the compression if the timing belt or timing chain is out of time by one tooth?
... What happens to how the engine runs if the timing belt or timing chain is out of time by one tooth?

... How do you remove and install a spark plug?
... What if the spark plug is stuck?
... Where - how much anti-seeze do you use on spark plugs?
... Where - how much silicone grease do you use with spark plugs?

Ignition System Theory 

... How does the ignition system take 12 volts from the battery and raise it to 25,000 volts for the spark plugs?
... How do you test the ignition system with a 12 volt test lamp?
... What does it tell you about the primary ignition system if the test lamp flashes but there is no spark?
... What does it tell you about the secondary ignition system if the test lamp flashes but there is no spark?
... What does it tell you about the ignition system if the test lamp does not flash?


... Why wear gloves? (for heat and oil)
... Safety around opening fuel lines and replacing fuel filters
... Safety around using battery chargers so you do not risk the battery exploding
