Do-It-Yourself: Internal Combustion Engine

Let us show you how to make an internal conbustion engine at home. It’s not that you will be able to use it somethere, but it’s going to be enough to wow your friends.

So, you’re going to need a can, CD, some foam rubber, a couple of screws and a few clips.

Here’s the can (we chose sprats in tomato sauce).

Eat the sprats and wash the can.

Take the foam rubber.

Cut out a circle. Make its diameter a couple of millimeters smaller than the diameter of the can, while its height should be a little more than the half of the height of the can.

Make a hole in the center of the cover for a connecting rod.

Pierce the foam rubber circle with a screw and fix it with washers from both sides. Tighten the screw. Then solder a piece of a straightened clip.

Insert a displacer into the hole in the cover and solder the can. At the end of the clip, make an eyelet and make one more hole in the cover which will be a little bigger than the previous one.

Use more clips to make supports for the crankshaft. Pull some polyfilm on the cylinder and fix it with a thread. It’s going to be a membrane.

Take a piece of a clip and a rubber cork to make two connecting rods.

Stick the one with the cork to the membrane and the other one to the displacer.

Made legs out of clips and solder them to the can. Then fasten a flywheel (the CD) to the crankshaft.

  1. That is not an INTERNAL combustion engine but an EXTERNAL. As you can see there is nothing energy providing INSIDE the combustion chamber… only the EXTERNAL candle.

  2. If he added a hand- wound generator, I’ll bet he could output .95 candlepower with it. Fun thing to fool with after several beers with your buddies.

  3. Nice model, but please DO listen to the comments correcting your title.
    This is NOT an internal combustion engine.
    It IS an external combustion engine.

    No one is criticizing your work, it is indeed a fine job. But the title needs to be corrected or it will confuse more people and students will give wrong answers in their class !!
