#2 - Automotive - Engines

In this lesson, we look at engines.

For most cars and trucks, we use a 4-Stroke Engine.

For most small engines (scooters, chainsaws, ...) we use a 2-Stroke Engine.

The 4-Stroke Engine

If you have never seen a 4-Stroke engine before, watch this 8-minute video.  It's okay if it doesn't make a lot of sense now.

Borrowed from YouTube (because of too many distracting overlays)

Now Test Yourself (with a partner)

The video below has no talking and only music. 
Get a partner.  Can you explain what is happening?
Be sure to watch at 35 seconds when the colours help you see where combustion is happening.  
(This coloured animation helps to show that combustion is only happening once at any given time.)

Next Steps

Now we are going to move to the official NB engine curriculum provided by CDX Auto.    You will need to use this login information.     ----->

1. Watch this video explaining 4-Stroke Engines.
   If it doesn't work in Google Chrome, it should work in Internet Explorer. Since you watched the above videos, this should be review.
   
   
2. Try out this 4-Stroke Engine animation.  
   These allow you to go through the different stages of the engine to help your understanding.
   (This animation is only basic, so use the bottom controls.)
   
   
3. Try this detailed animation of 4-Stroke Engine Mechanical Components. Check out all the buttons (bottom left) as there's lots of information here.
   
   
4. If that's not enough, you can try this animation sequence showing you what to test.   (Warning, you have to go through each test in order, waiting for each test to complete, or you won't see all the tests.)
