An extremely interesting and useful video that has already received more than 8 million views on YouTube. In it, the author makes a working version of an internal combustion engine from a conventional refrigerator compressor. Moreover, the top cover of the cylinder is made of transparent acrylic, as a result of which all ongoing processes and combustion of gases in the combustion chamber are clearly visible. The engine has all working components: ignition system, carburetor power system, etc.
It is definitely recommended for all DIYers to watch.
