Specific embodiment
As shown in Figure 1, a kind of four-stroke rotor engine, including engine cylinder body 1, engine intake 2, engine point
Firearm 3, engine exhaust port 4, engine rotor 5, engine output shaft 6, rotor gear ring 7, central gear 8, rotor seal end
9, rotor seal item 10, engine intake 2 are placed in the upper left side of engine cylinder body 1, and engine exhaust port 4 is placed in hair
The upper right side of motivation cylinder body 1, engine ignition 3 are placed at the top center of engine cylinder body 1, in engine rotor 5
Engine output shaft 6 is equipped at the heart, rotor gear ring 7 is mounted on engine rotor 5, and central gear 8 is fixedly mounted on engine
Cylinder body 1 and with 7 internal messing of rotor gear ring, rotor seal end 9 is mounted on the two sides of engine rotor 5, and rotor seal item 10 surrounds
It engine rotor 5 and is fixed at rotor seal end 9.
As shown in Fig. 2A to Fig. 2 D, the combustion chamber of engine cylinder body 1 is divided into two by engine rotor 5 and rotor seal item 10
A separate space, in 5 rotation process of engine rotor, the volume of two separate spaces of this engine cylinder body ceaselessly becomes
Change, four air inlet, compression, work done and exhaust courses of work, each course of work of engine are completed inside engine cylinder body 1
It is carried out in the different separate spaces inside engine cylinder body 1, hence it is evident that be different from reciprocating-piston engine, reciprocating piston
The Four processes of engine are in the closed chamber office work of a cylinder body.
Engine working process: the working principle of rotor-reciprocating engine as shown in Fig. 2A, Fig. 2 B, Fig. 2 C, Fig. 2 D
It is as follows:
As shown in Fig. 2A, engine rotor 5 is rotated counterclockwise by 0 degree to 120 degree, and engine intake 2 is opened, newly
Fresh fuel oil passes through engine intake 2 and enters engine chamber after mixing with air, while engine exhaust port 4 is opened,
When engine rotor 5 is diverted to 240 degree of positions by 120 degree of positions counterclockwise, the engine of engine right side closed chamber does work
Oil gas discharge after burning, since the volume of airtight chamber on the left of engine chamber changes from small to big to which absorption is more fresh mixed
Conjunction oil gas enters engine chamber and starts when engine rotor 5 is rotated counterclockwise from 240 degree of positions to 360 degree of positions
Machine air inlet 2 is closed, and is filled with fresh mix oil gas in the closed chamber of the engine chamber of 5 lower section of engine rotor.
As shown in Fig. 2 B, the compression process of engine, when engine rotor 5 is transferred to 360 degree by 0 degree of position counterclockwise,
Fresh mix oil gas below 1 combustion chamber of engine cylinder body is squeezed into the top of 1 combustion chamber of engine cylinder body by engine rotor 5.
As shown in Fig. 2 C, fresh mix oil gas is squeezed into engine chamber by the work of engine, engine rotor 5
When top, the igniting of engine ignition 3 is ignited fresh mixed oil and gas, and the mixed oil and gas in engine combustion room pushes after lighting
When engine rotor 5 turns to 360 degree by 0 degree counterclockwise, the mixed oil and gas after burning is pushed into engine cylinder by engine rotor 5
The lower section of 1 combustion chamber of body.
As shown in Fig. 2 D, the exhaust process of engine, when engine rotor turns to 120 degree by 0 degree of position, engine
Exhaust outlet 4 is opened, and the mixed oil and gas after burning below engine chamber is slowly squeezed out engine combustion by engine rotor 5
Room, when engine rotor 5 is turned at 360 degree of positions by 240 degree of positions, engine exhaust port 4 is closed, so far engine one
A working cycles are completed.
Compared to existing rotary engine, the utility model by the gear ratio of engine rotor gear ring and central gear by
3:2 is changed to 2:1, engine rotor when the every rotation four of engine output shaft is enclosed in four courses of work of rotor-reciprocating engine
From taking two turns, engine ignition does work twice, i.e., the every rotation of engine rotor take two turns (720 degree) when engine acting once, because
The rotary engine impulse stroke time of this utility model increases, so that engine rotor forms lesser torsional wave when operating
It is dynamic, so that engine operating is more steady smooth, the cylinder compression ratio of engine is improved, also improves the transmission effect of engine
Rate；The utility model changes the shape of engine rotor and engine cylinder body simultaneously, so that the motion profile of engine rotor
Match with the inner wall shape of engine cylinder body, while engine rotor is directly installed on engine output shaft and can effectively subtract
Noise when engine operating is lacked.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
