How a putt putt engine works.

19-12.14

A pop pop boat works by pulses instead of a flow. Most pop pop engines have two exhaust tubes because when the operator puts water in the engine the operator wants water to come out the other tube to tell them that the engine is full.

When the engine is full of water and you heat the engine up, some of the water turns into steam which then shoots the water out. The momentum and force of the leaving water, causes the boat to go forward. The pressure is greater outside than in the engine making the water rush back.

The steam bubble then condenses, creating a vacuum which draws water back in through the exhaust tube. The cooled water that is brought back into the boiler is then heated and flashed into steam, and the cycle repeats.

The boat goes forward because when it shoots out water it goes in one direction and when it sucks in water it pulls the water from many directions making the boat go forward and then slow down and go forward again. This cycle repeats until the flame goes out.

You can get many engines but the two most common engines are the flat and the coil engine. I’m going to talk about the flat engine first. The flat engine is a simple engine and is the most powerful engine I have seen so far. They are easy to make but are a lot of money. This engine is a medium sound and is good for small boats.

Now for the coil one it is simpler then the flat boiler and is soundless. All you need for this engine is a hollow copper rod. The closest engine to the pop pop engine is the valveless pulse jet engine. The putt putt boat was in the Boy Scouts of America but it was named jet boat. There are many names for the putt putt boat.

I have never wrote an essay on something like this and that is the end and hope you like it. But before I end I will give you two websites:

1. Pop pop boat – Wikipedia, the free encyclopedia

2. How to Make a Simple Pop Pop Boat – YouTube
