Self-made miniature single-cylinder external combustion engine
The external combustion engine was a type of heat engine. It was a device that provided power by expanding the gas when it was heated and compressing it when it was cold. The principle was that a certain amount of gas was filled in a closed cylinder. One end of the cylinder was a hot chamber, and the other end was a cold chamber. The gas was compressed in the low-temperature cold chamber, and then circulated to the high-temperature hot chamber to be quickly heated, causing the pistons to move back and forth. The fuel burned continuously in the combustion chamber outside the cylinder and was passed to the gas through the heater. The gas did not directly participate in the combustion and was not replaced. Self-made miniature single-cylinder external combustion engine required the following experimental equipment: alcohol lamp, air cylinder, power cylinder, connecting pipe, small wooden board, fan blade, miniature ammeter, small magnet, coil, etc. The specific experimental steps were as follows: 1. Check whether the gas in the cylinder is sealed or not, and gently turn the wheel to observe whether the cylinder is pushed up by the cylinder. 2. Light the spirit lamp and heat it with an external flame. Let it stand for 1 to 2 minutes. 3. He gently turned the wheel to make it work. 4. Observe the experimental phenomenon. 5. When the experiment was over, the alcohol lamp had to be extinguished first before the rotation of the motor was stopped. At the same time, there were also the following precautions: 1. The two cylinders of this teaching aid were made of glass and should be handled gently to avoid collision with hard objects. During the heating process, avoid water droplets on the cylinder to prevent sudden cold and explosion. During the experiment, the personnel could not leave. When the rotation stopped, they had to take it away from the fire source. They could not heat it for a long time. 2. Steam is easy to condense in the power cylinder, which will cause the power cylinder to be stuck. Treatment method: If it is slightly condensed, you can pull out the connecting pipe at the end of the power cylinder, blow it at the power cylinder with a hot air fan, and at the same time, turn the rotating wheel several times until the steam is discharged. If it is heavily condensed, you should pull out the power cylinder's valve and wipe the water vapor in the valve and cylinder with a clean cloth. Check the sliding resistance during assembly. 3. In order to discharge the water vapor in the cylinder out of the system, corresponding measures need to be taken (the reference material does not specify the specific measures, and may need to be determined according to the actual situation).

What material is the engine cylinder head made of?
The engine cylinder head was generally made of aluminum alloy. The aluminum alloy had good thermal conductivity, which could effectively reduce the engine temperature and ensure that the engine would not be overheated during continuous high-speed operation. In addition, the aluminum alloy material could also reduce the weight of the entire engine and improve the acceleration performance of the car. The application of aluminum alloy engine cylinder head can improve the performance index of the entire engine, including improving fuel economy, engine power and response, reducing noise, vibration and impact, and improving the reliability and safety of the car.
The world's earliest internal combustion engine
In 1860, the first successful commercial internal combustion engine was developed. But before that, many engineers and scientists had made promising attempts. For example, about 50 years before Renoir, the French engineers Nicepelle and Claude Nicepsey created an internal combustion engine called the Pyréolophore, which was fueled by a mixture of moss, coal dust, and resin. Francois Issac De Rivaz invented an internal combustion engine powered by hydrogen and oxygen, which used electric sparks as an ignition device and was installed on a carriage. The car became the world's first internal combustion engine car. In 1823, Samuel Brown obtained the first patent for an internal combustion engine that could be used in industrial production, namely the " gas vacuum engine." In 1826, Samuel Morey of the United States developed a non-compressed gas or steam engine with a vaporizing; in 1833, Lemuel Wellman Wright of the United Kingdom invented a tabletop double-acting gas engine with a water-jacket cylinder; in 1838, William Barnett developed what was considered the first engine to use cylinder compression. However, from a commercial success point of view, the internal combustion engine developed by Adrian Renova was the earliest. The novel " Hundred Years of Spaceship " is equally exciting.

Mining mines prone to spontaneous combustion and spontaneous combustion of coal seams
A series of fire prevention and extinguishing measures should be taken in mines that are prone to spontaneous combustion and spontaneous combustion coal seams. These measures include setting up observation stations or observation points for spontaneous combustion, arranging them in rock formations or coal seams that are not easy to spontaneously combust, adopting retreating mining, leaving no roof protection coal, etc. In addition, it was necessary to prepare a special design for mine fire prevention and extinguishing, and adopt technical means such as injecting mortar, injecting noble gas, spraying chemical inhibition agent, etc. to implement active prevention. The mine should also establish a natural combustion monitoring system to detect and discover changes in gas concentration and temperature in a timely manner, and carry out early warning and measures to improve and improve. Comprehensively consider the management of the goaf after mining, the fire prevention and extinguishing needs of the adjacent working faces and adjacent coal seams to ensure safe mining.
