4F30.52 - Gas Engine Model

See paragraph one in the procedure section.
Code Number:
Demo Title:
Gas Engine Model
4 cycle engines
Area of Study:
Heat & Fluids
Gas engine model.

Make sure the batteries in the power module are in good shape.  Turn on the power module and observe the engine parts.  The moving parts will all be seen to move in correct sequence.  In particular, note the movement of the valves, pushrods, camshaft, piston, and crankshaft. The firing order is shown by the LED's that serve as spark plugs.
