Embodiment approach 1

[0069] Implementation method one: the structure includes two ring-shaped cylinders 3 and 4 whose inner cross-sections are semicircular to form a set of annular cylinders whose inner cross-sections are circular. The outside of the sleeve is designed according to the cooling requirements; the gear box is set on both sides of the cylinder, such as figure 1 , 2 , 3, 4, and 5; the cylinder block is provided with a strip-shaped air intake hole 20 and an exhaust hole 21, and the strip shape of the intake and exhaust holes is arranged according to the direction of piston rotation. One end of the hole in the forward direction of the piston can be set in a circular arc shape, and the other end can be flush, so that the piston ring can pass smoothly while quickly completing the intake and exhaust; especially at the beginning of the exhaust port, The exhaust port can be opened wider, so that the angle of the exhaust advance angle can be reduced as much as possible, so as to facilitate t...

Embodiment approach 2

[0070] Implementation method 2: Two annular cylinder blocks 42, 43 with semicircular inner cross sections are provided to form a set of circular annular cylinder blocks with circular inner cross sections, which are combined with the gear box cover 41 to form a set of internal combustion engine cylinder blocks; The gears are all arranged on the same side of the cylinder block, and two rotors 12, 13 are housed inside, and two rotor shafts 39, 40 are installed on the two rotors respectively; The circular gear 8 and the rotor 13 are connected and assembled as one, and the rotor shaft 40 passes through the rotor shaft 39 to connect and assemble the non-circular gear 7 and the rotor 12 as one, as Figure 31 , 32 As shown; in addition, the center of the rotor shaft 40 is provided with a lubricating oil passage, and the lubricating oil passage is drawn from the middle part of the two rotors for the lubricating oil to flow out for lubrication between the two rotors (not shown in the fi...

Embodiment approach 3

[0071] Implementation method three: on the basis of implementation method one, two sets of internal combustion engines are connected in parallel, two non-circular gears 7 and two non-circular gears 8, one eccentric gear 9 and one eccentric gear 10, two non-circular gears Mesh with one of the eccentric gears together, and output power through a power output shaft; Figure 33 , 34 , 35, and 36, 8 pistons are respectively assembled in two cylinders, and the distribution of cylinders and pistons is as follows Figure 39 shown.

Abstract

The invention discloses a piston rotation type internal combustion engine. An annular air cylinder with the circular inner section is formed by two annular cylinder bodies with the semicircular inner sections. Two pairs of pistons are arranged in the cylinder bodies. Two noncircular gears and two pairs of pistons are assembled into a whole through a transmission mechanism to be engaged with two eccentric gears on the same power output shaft, and power is output through an eccentric gear shaft. A special piston ring lubricating mechanism and a special piston cooling system are further arranged. Cylinder sleeves made of heat resisting materials are adopted in the parts, at the combustion expansion acting section part, of the cylinder bodies, the sections of cylinder sleeves are isolated from other machine bodies through heat isolation materials, accordingly, the parts, at the combustion acting section, of the cylinder bodies are constantly kept at the high-temperature state, combustion of mixed gas is better facilitated, combustion of the mixed gas is more rapid and more thorough, and the heat efficiency is higher; and various design schemes of serial connection and parallel connection combinations of multiple cylinder bodies and various arrangement schemes of engagement of the noncircular gears and the eccentric gears exist, efficiency is higher, and the output power is larger.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to a piston rotary internal combustion engine. Background technique [0002] Existing reciprocating two-stroke internal combustion engines have high fuel consumption, low thermal efficiency, and high pollution; four-stroke internal combustion engines have complex intake and exhaust valve systems, high power consumption, and pistons, piston rings, and cylinders are always in a state of side friction, which increases friction and increases The loss of power is increased, and their complex crankshaft connecting rod mechanism and the reciprocating motion of the piston not only consume a lot of power, but also increase the dynamic load and bearing wear of each force-bearing part due to its complex inertial motion, and also increase the The vibration of the engine seriously affects the improvement of the rotating speed, thereby further improving the performance of the internal combustion e...
