Embodiment Construction

[0024] Depend on figure 1 It can be known that the assembly structure of the ring cylinder engine is: piston (2) is housed in the cylinder block (1), and piston (2) and rocking arm (4) are all fixedly connected on the rocking arm shaft (3). The rocking arm (4) is hinged with the small end of the connecting rod (5), and the big end of the connecting rod (5) is hinged with the crank pin on the crankshaft (6). The creation axis of the inner wall surface of the cylinder body (1), the creation axis of the outer surface of the piston (2), and the center line of the rocker arm shaft (3) are three coincident lines. The piston (2) can swing around its axis and relative to the cylinder (1) in the cylinder (1).

[0025] exist Figure 4 In the shown first embodiment, the cylinder body (1) is fixedly connected with the central shaft (10), the cylinder body (1) is equipped with a cylinder head (11), and the cylinder body (1) is equipped with a piston (2), Piston (2) and rocking arm (4) a...

Abstract

The invention relates to a ring cylinder engine which can obviously reduce engine friction power consumption, reduce the restriction of piston inertial force and linear velocity to the engine, simplify the engine structure, reduce engine manufacturing and use cost and widen the application field of new heat engine materials. The engine comprises a new ring curved surface cylinder and a piston, the restriction mode of a revolute pair is used for substituting a movement pair between a cylinder and a piston of the traditional reciprocating piston engine, so that no direct contact exists between the engine cylinder and the piston, the movement pair is also not in direct contact with fuel gas, and thus, various defects caused by direct contact of the movement pair used by the traditional reciprocating engine cylinder and the piston with the fuel gas are avoided. The greatest friction power consumption source of the traditional reciprocating piston engine is eliminated, and the heat efficiency of the engine is improved. The invention eliminates an impact between the engine cylinder and the piston, provides a possibility to manufacture the engine cylinder and the piston by using high temperature structural ceramics and also provides a possibility for the engine cylinder and the piston to thoroughly get rid of the restriction of linear velocity.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to an annular curved surface cylinder piston engine. Background technique [0002] It is well known that the cylinder of a traditional reciprocating piston engine exists kinematically as a constraint of the piston, and there is force and relative motion between the cylinder and the piston. A well-designed traditional reciprocating piston engine consumes more than 50 percent of its total frictional power consumption due to the friction between the cylinder block and the piston, and the frictional power consumption varies with the engine speed. increased sharply. Due to the existence of friction, due to the limitation of material properties, the cylinder and piston must be well lubricated and cooled, otherwise they will quickly fail due to wear, friction and overheating. Since the cylinder body and the piston are in direct contact with the gas, it also brings disadvantages to the nor...
