Problems solved by technology

However, traditional engines are subject to a single working cycle mode, with low efficiency and poor adaptability to working conditions
At present, the electromechanical hybrid has become the development trend of the power system, but the structure of the traditional engine is low in integration with the motor, the system structure is not compact, and the power coupling is difficult. In addition, there are the following defects:
[0003] 1. The crankshaft connecting rod piston engine has complex structure, large volume, loose space layout, large vibration and loud noise during use, and there is an included angle between the connecting rod and the piston axis, and a large deflection angle is formed under the condition of large force , forming a radial thrust on the piston, increasing the mechanical loss and increasing the wear of the piston / cylinder liner
[0004] 2. The thermodynamic cycle mode is single, the adaptability to working conditions is insufficient, and the energy efficiency level is low under non-ideal working conditions
[0005] 3. The power-to-weight ratio of the traditional piston engine is small, and it is difficult to realize a large power solution. The heavy-duty piston engine is not only large in size and heavy in weight, but also very difficult to manufacture
[0006] 4. When building a hybrid electric power system, electromechanical matching is poor, coupling is difficult, and the degree of structural integration is low. The entire system has complex structure, large volume, and low power-to-weight ratio

Description

technical field [0001] The invention relates to the field of engines, in particular to a dual-rotor variable cycle deflagration piston engine. Background technique [0002] The engine is the core power source of the modern industrial system and one of the core mechanical equipment for production and life, occupying a very important position, although the existing technology is mature and widely used. However, traditional engines are subject to a single working cycle mode, with low efficiency and poor adaptability to working conditions. At present, electromechanical hybrid has become the development trend of the power system, but the structure of the traditional engine is low in integration with the motor, the system structure is not compact, and the power coupling is difficult. In addition, there are the following defects: [0003] 1. The crankshaft-connecting rod piston engine has complex structure, large volume, loose spatial layout, large vibration and loud noise during ...
