Problems solved by technology

However, its structure is complex, not compact, and the inertial force is not suitable for balance, resulting in excessive vibration, which is easy to reduce the service life of the engine, and also causes structural damage, which increases the cost of maintenance and replacement. In addition, the huge inertial force of the piston connecting rod during high-speed operation. A large lateral force acts on the inner wall of the cylinder, resulting in a large friction loss of the piston ring and reducing the life of the piston ring and cylinder

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and refers to an annular reciprocating piston engine and a double row annular reciprocating piston engine widely applicable to different power machines such as motor vehicles, motor boats, and small generators. Background technique [0002] In the development history of the internal combustion engine for more than one hundred years, there have been many engines with different structural principles, especially different rotary engines, but they have not been able to challenge the absolute dominance of the reciprocating piston engine. However, its structure is complex, not compact, and the inertial force is not suitable for balance, resulting in excessive vibration, which is easy to reduce the service life of the engine, and also causes structural damage, which increases the cost of maintenance and replacement. In addition, the huge inertial force of the piston connecting rod dur...
