Description
Technical field
The invention belongs to stroke piston combustion engine technical field, lived more particularly, it relate to a kind of rotation of block form
Fill in internal combustion engine.
Background technology
Stroke piston combustion engine（Gasoline engine, diesel engine）, its recoverable amount ranks first in dynamic power machine, is widely used in
The fields such as automobile, agricultural machinery, engineering machinery, ships, battlebus, helicopter and other light aerocrafts.Stroke piston combustion engine
From the perspective of design, however it remains three major issues：
1. valve type distribution device
Valve type distribution device is in intake process, and coefficient of charge is mutually restricted with induction air flow ratio, and induction air flow ratio is higher, fills
Coefficient of discharge is smaller, inversely.When air inlet mean flow rate is more than 0.5 Mach, coefficient of charge starts drastically to decline.Designer
Many air valves design is used on stroke piston combustion engine, slows down induction air flow ratio in the way of increasing air inlet area, obtains as far as possible
Obtain maximum coefficient of charge.The disadvantage of this measure is mainly the kinetic energy for being difficult by charge air flow, is formed in cylinder and meets emission reduction reality
Gas motion form and intensity that border needs, are unfavorable for the formation and burning and PM emission reductions of gaseous mixture.Many air gate distributions are made simultaneously
It is more complicated into structure, the manufacturing cost of valve actuating mechanism greatly improved.
2nd, residual gas problem
Stroke piston combustion engine is due to structure, and the high-temp waste gas after burning can not be directly affected down all by emptying
The air inflow of one wheel, the particularly influence to gasoline engine are bigger.Because the combustion type of gasoline engine is premixed combustion, work as gaseous mixture
When input is less, gaseous mixture is seriously diluted by high temperature exhaust gas, can only enriching gaseous mixture, the row of causing to ensure trouble-free burning
Dirt increases.
3rd, toggle
Toggle is as a kind of mechanical motion mechanism, and itself is without any problem.But it is used on internal combustion engine, forms past
When bringing back to life piston type internal-combustion engine, very big disadvantage is brought.Piston is mainly manifested in do reciprocating linear motion and drive by connecting rod bent
During axle rotates, cross component force, inertia force very big, that be helpless to bent axle rotation etc. can be produced, great wave is caused
Take, also increase abrasion, the vibration and noise of complete machine of piston and cylinder sleeve.Simultaneously because the reason for toggle, making whole
The volume of individual internal combustion engine is larger.
The content of the invention
In order to solve three major issues present on stroke piston combustion engine, I have invented block form rotary piston internal combustion
Machine.It is mainly characterized in that：The air inlet of stroke piston combustion engine, compression, acting, exhaust four stroke are divided into two, one
Individual cylinder completes air inlet, compression, and another cylinder completes acting, exhaust, and two cylinders couple side by side, between two cylinders by rotate aeroscopic plate and
When by the gas compressed be sent to acting cylinder complete acting, exhaust.
Specific structure and principles and methods are as follows：
Referring to Fig. 1：Piston 2 is made bias in compression cylinder 1, rotated in an anti-clockwise direction.Slide plate 3 on piston is in spring 5

Main shaft is rotated together, and several air guide through holes are provided with aeroscopic plate 2.Width per single air guide through hole is less than slide plate thickness, air guide
The position of through hole and quantity, which should be able to be met, to compress the gas got well, and acting cylinder is sent in time.
Referring to Fig. 1：When the slide plate rotated with piston turns over air inlet, aeroscopic plate is with main shaft synchronous axial system, air guide
The air guide through hole that air guide through hole on plate is covered with common port is offset from each other, and air guide channel is closed.Now, due to two in cylinder
Individual slide plate is close to cylinder inner wall and piston outer mold surface respectively, and gas is sealed.Piston is rotated further, and gas in the jar is compressed.
When gas is compressed to the compression ratio of setting, with the air guide through hole on the aeroscopic plate of main shaft synchronous axial system, start and common port
The air guide through hole covered is overlapped, and air guide channel is opened, and compressed gas is sent into acting cylinder in time.Main shaft is rotated further, air guide
The air guide through hole that air guide through hole on plate is covered with common port, the registration of holes changes from small to large and from big to small, until
Compressed gas is all admitted to acting cylinder, and holes mutually staggers, and air guide channel is closed.Simultaneously as air admission hole is normally opened, the position in hole
Put as shown in figure 1, when piston is rotated forward, forming vacuum in cylinder, live gas is continually sucked.That is, working as
When compressing cylinder working, the compression and air inlet of gas in the jar are to carry out simultaneously.Piston is rotated further, and starts next round circulation.
Referring to Fig. 3：When Fig. 3 is that compressed gas is all sent to acting cylinder, the structural representation for cylinder state of doing work.Do work cylinder with
The basic structure of compression cylinder is the same, is at main difference：In order to supply gas conveniently, the installation site of slide plate and compression on acting cylinder body
The installation site of slide plate mutually staggers an angle on cylinder body.When compressed gas is all sent to, the timely oil spout of atomizer, burning
（Lighted a fire in time during for gasoline engine）, gas pressure is improved, promotes piston to rotate forward, until cross steam vent, gas is from normal
The steam vent discharge opened, acting terminates.It is the same with compression cylinder, piston one side by gases at high pressure promote rotate forward it is same
When, piston another side releases last round of residual gas from steam vent, that is to say, that acting is to carry out simultaneously with exhaust.Mirror
In combustion-chamber shape, gas is not easy to form vortex, and to improve combustion efficiency, spy takes multiple spot oil spout（Adopted during for gasoline engine
Use multi-point spark）.Piston is rotated further, and starts next round circulation.
Referring to Fig. 4：Fig. 4 is structural representation when two cylinders couple side by side.Compression cylinder 8,9 liang of cylinders of acting cylinder side by side, are mounted in
On main shaft 1, public end cap 5 and aeroscopic plate 4 are housed between two cylinders, two outsides fill left end cap 10 and right end cap 3, right end cap 3 respectively
In be embedded with the clamp 2 being made up of two and half garden rings, to prevent the axial float of main shaft 1, after all adjusting, with bolt 7 and spiral shell
Cap 6 is locked.To prevent in motion process, occur relative displacement between two cylinders, alignment pin can be stamped in position.Two
The piston of cylinder and the aeroscopic plate of centre are coupled using key with main shaft 1, are rotated with main shaft 1, position of each key on main shaft
