Ingredients and Function

Part of Lesson Plan: **Ingredients to Internal Combustion (updated) by Thomas Dougherty

Activity Overview / Details

While the animation is running , I will explain the necessary ingredients to internal combustion:

Fuel, Ignition and Compression.

If the engine has these three ingredients at the proper time it will run. If an engine does not run, it is missing one of the ingredients.  Students will learn that fuel is introduced on the intake stroke, compression takes place on the compression stroke and ignition takes place at the top of the compression stroke.  The animation illustrates the fuel/air charge in blue and combustion and exhaust in red.  Students will be able to correlate these illustrations to invisible events on the actual engine by observing and comparing the positions of the piston and valves.
