Part - 2 ( CRAWLER TRACTOR THAT WORKS WITH FIRE )

► See the full rewiel of the crawler tractor in this video:

From the first moment I got to know this engine, I immediately noticed that it was an engine with unusual characteristics. I found that the piston strokes are relatively large, approximately 16 mm, considering the 12 mm diameter of the piston. Even so, the engine reached records in rotations (2900rpm) and maintained excellent torque.

My engine hit 1900rpm with 30mm strokes for each piston, practically twice as much and 14.5mm in diameter. In both examples, we have good rotation and good torque. Obviously mine has a lower speed, but on the other hand, it's among the highest torque motors I've made.

I was surprised by the 2500rpm when riding on a flat track and much more impressed by the 2900rpm in free spin. Considering its low displacement of 3.62 cc, it still shows a good breath of torque. In addition to the test carried out in the video, I have already performed another experiment, where the war tank pulled up 900 grams of weight and its rotation remained at 1500rpm. All this power is admirable, I didn't imagine so much torque, the engine starts to lose torque at rotations close to 600rpm.

It does not need lubrication on the pistons, only after a long time, it is interesting to put grease on the joints.

Even without a liquid cooling system, it heats up to the point of burning your fingers, but it doesn't stop it from running continuously for hours.

I also observed, in addition to the good performance, it is a well-designed project, aiming to reduce the manufacturing cost. Because only a 5 ml glass syringe was used, to make the two cylinders and pistons, very well thought out.

The use used high temperature silicone o-ring to secure the glass syringes and test tube to the aluminum block, allowing for possible replacement of the glass cylinder.

► Features:
- The stroke of each piston is 16 mm and 12 mm in diameter for each piston and even with a stroke a little longer than usual, it reached this high rotation.
- Total weight is 1,263 grams fueled.
- Only the motor has a weight of 420 grams.
- The length of the cold piston is 20 mm.
- The length of the hot piston is 50 mm.
- The length of the connecting rod is 51 mm.
- The test tube is 40 mm long, 16.5 mm outside diameter and 14 mm inside diameter.

Thank you all for the attention.

*► ENGLISH:* ► Why is it considered a Stirling engine?
- Because it is an external combustion engine, it works in an open cycle, that is, the cylinder sucks in the fire; different from Stirling which operates in a closed cycle.

► HOW DOES THIS ENGINE WORK?
The engine works with the difference in temperature between the hot cylinder and the cold cylinder, where its operating cycle works with the air confined inside the engine, without contact with the external environment.
When the air takes off into the hot cylinder, it is heated and the air expands, with this volume change, it pushes the piston, then the reverse cycle occurs, sucking the piston with vacuum.
This engine is called a "Stirling engine".

*► PORTUGUÊS:* ► Porque é considerado um motor Stirling?
- Porque é um motor de combustão externa, o seu funcionamento é em ciclo aberto, ou seja, o cilindro aspira o fogo; diferente do Stirling que opera em ciclo fechado.

► COMO FUNCIONA ESTE MOTOR?
O motor funciona com a diferença de temperatura entre o cilindro quente e o cilindros frio, onde seu ciclo de funcionamento funciona com o ar confinado dentro do motor, sem contato com o ambiente externo.
Quando o ar descola-se para o cilindro quente, ele é aquecido e ocorre a expansão do ar, com essa variação de volume, empurra o pistão, em seguida ocorre o ciclo inverso, sugando o pistão com o vácuo.
Este motor se chama "motor Stirling".

*► INDONESIA:*► Mengapa dianggap sebagai mesin Stirling?
- Karena ini adalah mesin pembakaran luar, ia bekerja dalam siklus terbuka, yaitu, silinder menyedot api; berbeda dengan Stirling yang beroperasi dalam siklus tertutup.

► BAGAIMANA CARA KERJA MESIN INI?
Mesin bekerja dengan perbedaan suhu antara silinder panas dan silinder dingin, di mana siklus operasinya bekerja dengan udara yang dikurung di dalam mesin, tanpa kontak dengan lingkungan luar.
Ketika udara lepas landas ke silinder panas, dipanaskan dan udara mengembang, dengan perubahan volume ini, mendorong piston, kemudian terjadi siklus sebaliknya, mengisap piston dengan vakum.
Mesin ini disebut "Stirling engine".

*► ESPAÑOL:* ► ¿Por qué se considera un motor Stirling?
- Por ser un motor de combustión externa, trabaja en ciclo abierto, es decir, el cilindro aspira el fuego; diferente de Stirling que opera en un ciclo cerrado.

► ¿CÓMO FUNCIONA ESTE MOTOR?
El motor trabaja con la diferencia de temperatura entre el cilindro caliente y el cilindro frío, donde su ciclo de funcionamiento funciona con el aire confinado en el interior del motor, sin contacto con el medio exterior.
Cuando el aire sale al cilindro caliente, se calienta y el aire se expande, con este cambio de volumen, empuja el pistón, luego ocurre el ciclo inverso, succionando el pistón con el vacío.
Este motor se llama "motor Stirling".
