In 1860, the lux model in france is designed and manufactured into a first practical gas engine according to the structure of a steam engine, in 1866, the Europe cloud in Germany successfully manufactures a1 st piston reciprocating type, single-cylinder and four-stroke internal combustion engine, so that a lot of scientists and a lot of train enterprises have accumulated to input huge manpower and financial resources to study the internal combustion engine and improve the internal combustion engine until the day 100, however, the fuel utilization efficiency of the internal combustion engine still is only 40%, and the energy utilization efficiency of a motor easily reaches more than 90%.

However, it is not difficult to find out the working principle of an internal combustion engine, which is inefficient because of the problem of the working mode. Modern vehicles and equipment mostly need a power source rotating circumferentially, and a piston type internal combustion engine adopts a reciprocating motion working mode. First, the reciprocating motion needs to be converted into circular rotation twice, the conversion process consumes energy, and the faster the speed, the higher the loss. Secondly, the reciprocating motion needs to continuously counteract inertia, and the faster the speed, the larger the weight, and the more energy is consumed to counteract the inertia. The internal combustion engine is designed by imitating the structure of a steam engine, and adopts a working mode of reciprocating motion of a piston, so that the efficiency is low, which is the constraint of the time background. When the motor is designed, the motor adopts circular rotation to do work at first, so that the efficiency is high.

The existing piston reciprocating internal combustion engine has low fuel utilization efficiency, and the piston reciprocating internal combustion engine has larger running vibration and noise,

When the piston reciprocating internal combustion engine is used for large-scale equipment and ships, the piston is heavy, and the inertia which needs to be counteracted is large when the piston is in reciprocating motion, so that the high-speed engine is abandoned, and the low-speed internal combustion engine is selected.

The internal combustion engine with the triangular rotor is also an internal combustion engine which is practically applied at present, but the internal combustion engine with the rotor is insufficient in combustion due to the fact that the rotor is not provided with the high compression ratio of the traditional internal combustion engine, so that the problems of increased oil consumption and pollution in emission can be caused.
