Antaradahanayantram – The Internal Combustion Engine!

Internal Combustion Engine or Antaradahanayantram

Don’t worry about the title. It means “Internal Combustion Engine” in Malayalam. In my taravadu at Kollam, I came across a book named “Kandupidithangalude Katha” or “The Tale of Inventions”. I got this word from that book. Being a fan of technology, I read about it. This was long before I learned about engines in school.

One day, I went to the back yard of my house at Kochi with a few items in hand. The intention was to create an antaradahanayantram! I took two caps of whiskey bottles and checked whether they closed on each other, which they did. Then I put a hole on top of one of them. Then I took another cap and made it a bit perforated on the side. I fixed that at the bottom of the other cap that did not have the hole.

So in effect I made a cylinder with several holes here and there. Then I made a small fan and fixed it on top of the single holed cap. I filled that cap with water and the perforated cap with kerosene. Then I put fire into the kerosene. The idea was that the kerosene will burn inside and then boil the water which in turn will make the fan spin through its steam.

I don’t know why I thought this was an internal combustion engine since it looked as if it was both internal and external. Anyway it was burning and boiling the water. Nothing was happening to the fan though. Then my dad came and asked what was I doing. I said proudly that this is my internal combustion engine. He asked me what is that and I said antaradahanayantram! He just warned me not to create an explosion and left.

I waited for some more time but nothing happened still. I was wondering what was going on. Then I noticed the flaw in my design. The steam has to come out of a narrow tube in order to utilize its power. I had just put a hole on top of the cap. So the steam was coming out just as it would if I am boiling water in an open vessel.

The design failed! I wound up my experiment and went inside. Sigh!
