The name comes from the noise made by some versions of the boats. Pressure and volume can be measured separately and coupled appropriately to obtain the P V diagram.
The area of the P-V diagram is the work done by the mediuII steam per cycle.
Putt putt boat engine cycle. The two-cycle engine was sometimes called the make-and-break a reference to the ignition system or one-lunger single cylinder and was instantly recognized by its puttputtbang sound as boats chugged through the water. Sound of two-cycle engine. Putt-putt boats are toy boats that propel themselves through water through the repeated firing of jets of water.
In each cycle water is expelled out of a pipe at the rear of the boat pushing the boat forward and then water is drawn in from the same pipe in preparation for the next cycle. The Putt-Putt Steam Boat can be used to demonstrate basic principles of Newtons Laws to students. K-PS2-2 2-PS1-2 3-PS2-2 MS-PS2-2 HS-PS2-1 The Putt-Putt Steam Boat can be loaded with water and candle fired up to investigate movement.
Students can run trials to determine which variable gives the best push to the boat. Putt Putt Boat. Blaxland 35 HP marine engine - YouTube.
A pop-pop boat is a toy with a very simple steam engine without moving parts typically powered by a candle or vegetable oil burner. The name comes from the noise made by some versions of the boats. Other names are putt-putt boat crazy boat flash-steamer hot-air-boat pulsating water engine boat.
Around the world they may be called Can-Can-boot Knatterboot toc-toc Puf-Puf boat. The device utilises energy that would otherwise slow the boat down to make it go faster. Numerically one cycle of the engine is split into two motions.
Lets say the total energy per cycle is ten units. The blow power represents around 50 of the total cycle energy. It is likely to be slightly higher than this due to the energy.
Two cycles of the putt putt sound recorded. One cycle of the boats operation can be thought to be composed of an ejection and suction. Thus the two bursts of pulses in a cycle that we see in this figure can be thought of as correspond ing to the outflow and inflow phases.
Sure I have some ideas but theyre all complicated and most likely will stop the engines cycle or at least will interfere with the engines cycle. This is actually not necessary as all we need to do is fill the tubes plus a couple of drops in the boiler as that is the state of an engine when it is running well but lets assume we do fill it. Cess that powers the putt-putt boat.
Every thermodynamic pro cess can be characterized by a cycle that can be depicted using a pressure-volume P-V diagram. Pressure and volume can be measured separately and coupled appropriately to obtain the P V diagram. The area of the P-V diagram is the work done by the mediuII steam per cycle.

This thread will be all-encompassing and the invitation is to bring any question you may have or any idea that you may want to share about Pop Pop Putt Putt Engines. How about a steam boat with no moving parts. Its called a putt-putt or pop-pop boat.
The principle is very simple. A pipe open at the stern of the boat has a closed end inside the boat that is kept very hot. Water enters the pipe and when it gets to the hot end it flashes to steam pushing the water out the pipe and propelling the boat forward.

Using simple materials that are easily sourced you can build a miniature steam boat that will propel itself around a. Back to the putt putt boat - after the explosive expansion phase water vapor begins to condense creating a partial vacuum. Since there is now a pressure differential between the atmosphere and the inside of the boiler the atmosphere pushes water into the boat engine.
The force is from the atmosphere not from suction. The very first putt putt sometimes also called pop pop boat patent was filed in 1891 in the UK but it is likely the toy was around for some time before it occurred to anyone to patent it. These boats can be a little fussy the airtightness of the boiler is especially important so Captain Nat the steam engineer will be proud if you.
