The invention relates to the technical field of engines, and in particular to a supercritical internal combustion direct current steam engine group. Background technique

One or more substances are rapidly burning in a certain space in a very short period of time, and a large amount of heat is accumulated in a short time, so that the gas volume rapidly expands, causing an explosion.

That is, the explosion is an extremely rapid physical or chemical energy release process. In this process, the material in the space releases the energy contained in it inside at an extremely fast rate, and transforms into energy forms such as mechanical work, light, and heat.

As is known to all, the current work cycle of a piston connecting rod crankshaft internal combustion engine, in the compression stroke, the piston compresses the atmospheric air into the combustion chamber to form a closed high pressure space, in which the high pressure air is fully mixed with the fuel, and all of them are simultaneously burned at the same time, which is The conditions for the explosion, that is to say the combustion chamber of the crankshaft connecting internal combustion engine, are the artificially created confined spaces for rapid combustion, that is, man-made controlled explosions.

Among them, the movement of the piston rod is the mechanical energy generated by the explosion. At the same time, the thermal energy generated by the explosion becomes a by-product of the internal combustion engine of the piston connecting rod, so it is called sub heat. Today's internal combustion engines produce high-temperature sub-heats above 1000 °C when doing work. However, the generation of high-temperature secondary heat has become an obstacle to the next work cycle. In order to start the low temperature of the next work cycle, people use the power of 3 to 5 percent of the work of the internal combustion engine to cool down the heat. The next work cycle is working properly. Specifically, the cooling system is used to remove heat from the cooling water. The power of the water pump and the cooling fan in the cooling system are derived from the power of the internal combustion engine.
