Hello everyone this is my air engine made using very simple parts like cardboard, disposable syringe, straw, pen end caps and bicycle spokes. I blowed air through mouth, use compressor for best results.

How much economical can you make your engine? Here it is costs only about Rs.10. Blowed air through mouth thats why produces lower rpm use compressor(i dont have one) iam sure it will give good results. Hope you all like my engine and video. Took nearly 20minutes to make the engine.

What acts as valves? Did you just drill a hole in the syringe wall to act like the exhaust port in a 2 stroke?
There are no valves i supply air through the mouth of the syringe and air exhausts through the mouth, its a timing mechanism. Look at the picture for some clarity in concept. <br> <br>http://imageshack.us/photo/my-images/819/220pxoscillatingcylinde.png/
hey how to like it da <br>
Good work! <br> <br>Maybe you could improve the efficiency adding a sliding contact between the hose and the air inlet. Thus the air will not get away.
Thank you rimar2000.
