Description
Technical field
It is a kind of planetary gear type rotary polygonal piston engine the present invention relates to internal combustion engine technologies field.
Background technology
The explosive motor that current automobile is used, typically all reciprocating-piston quartastroke engine, it is swollen by gas
Swollen promotion piston is moved back and forth and work done in cylinder, and the rotary motion for being converted to main shaft will will be moved back and forth by connecting rod crank
It is operated.Because intake valve port and exhaust valve port and air inlet, exhaust passage are more narrow and small, cause air inlet and exhaust obstructed,
And part energy is always consumed during reciprocating motion is converted into rotary motion, therefore cause existing resurrection plug four
Stroke IC engine it is less efficient, and crank reciprocating member make it that the mechanism of engine is complicated, fuselage both bulk, the range of speeds
It is narrower, engine is very limited in terms of speed is improved.The book number that People's Transportation Press 2003 year 2 months publishes is
ISBN7-114-04210-8's《Automobile construction (first volume)》To describe a kind of existing known triangle piston rotary for page 322

Just the requirement that quartastroke engine changes to volume of cylinder is met, when engine works, fuel gas passes through spark ignitor
Outburst, is transmitted to rotor journal by three-apexed rotor and promotes main shaft to rotate work done.Above-mentioned rotary engine is due to its air inlet and row
Gas is more unobstructed, therefore does not need valve mechanism, reduces frictional dissipation and washes the energy that valve spring is consumed open, and arranges
Gas is consistent with the direction of motion of expanding gas work done, and piston will not be reversed all the time, and rotor each rotation is by multiple combustion gas
Thrust, the energy of expanding gas is fully used for promoting main shaft work done, therefore has knot compared with reciprocating-piston quartastroke engine
The advantages of structure is simple, vibration is slight, work doing efficiency is high, power is big.But existing triangular piston rotary engine, due to it
Main shaft is eccentric crankshaft, causes the volume of engine larger, and because the compression of working chamber volume is smaller, makes the combustion of combustion gas

The positive pole of extraneous power supply is electrically connected, and cylinder block 3 is electrically connected by the negative pole of wire and extraneous power supply.When this hair
It is bright be petrol engine when, it is necessary to light the air mixture in combustion recess 29 by the timing arcing of spark plug 54.
Embodiment two：As shown in Figure 3, spark plug 54 is separately installed with each cambered surface of three-apexed rotor 4, spark plug 54
Arcing end is located in combustion recess 29 and the air mixture in combustion recess 29, the terminals of spark plug 54 are lighted in energy arcing
It is electrically connected by the positive pole of wire, carbon brush and ignition coil and extraneous power supply, cylinder block 3 passes through wire and extraneous power supply
Negative pole be electrically connected.By the way that spark plug 54 is arranged in each cambered surface of three-apexed rotor 4, when each cambered surface is rotated to successively
During the right part of cylinder block 3, by carbon brush and the momentary connection high-tension circuit of cylinder block 3 arcing, point occur for the terminals of spark plug 54
The air mixture in now corresponding combustion recess 29 is fired, so makes firing circuit not only simple but also rationally effective.
In addition, when the present invention is Diesel engine, then need not install spark plug 54, spark plug is replaced with fuel injector
54, fuel injector, which is provided with, can spray the oil spout end of vaporific diesel oil, oil spout end be located at cylinder type intracavitary, fuel injector by oil pipe with
Injection pump is connected, and diesel oil is sprayed into combustion chamber and forms oil mist particles by fuel injector, and equal with the air that is inputted by air admission hole 27
Even mixing, when the volume of working chamber 10 drastically becomes small, spontaneous combustion occurs for vaporific diesel oil and expansion working.
Above technical characteristic constitutes embodiments of the invention, and it has stronger adaptability and implementation result, can basis
The non-essential technical characteristic of increase and decrease is actually needed, to meet the demand of different situations.
The course of work of the embodiment of the present invention one and embodiment two is：With the work cambered surface AB and cylinder type of three-apexed rotor 4
Exemplified by the working chamber formed between face i.e. AB working chambers, illustrate the course of work of the present invention.The present invention starts with reciprocating-piston
Four stroke working cycles of machine are identical, including air inlet, compression, work done and exhaust Four processes.First, as shown in Figure 4, when three
When the angle top B of angle rotor 4 turns over 27 left side edge of air admission hole, AB working chambers start air inlet, due to air admission hole 27 and steam vent 28
Now it is connected, i.e. intake and exhaust are overlapping, at this moment the volume of AB working chambers is minimum, equivalent to the top dead centre of conventional engine
Position.Secondly, as shown in Figure 5, as controlled three-apexed rotor 4 is rotated further, the volume of AB working chambers gradually increases, flammable mixed
Close gas and cylinder is constantly inhaled into by air admission hole 27, when three-apexed rotor 4 is rotated by 90 ° position shown in arrival accompanying drawing 6, AB works
The volume for making chamber reaches maximum, and equivalent to the bottom dead center position of conventional engine, suction stroke terminates.Then, triangle
Rotor 4 is rotated further, and the volume of AB working chambers is gradually reduced, when the angle top A of three-apexed rotor 4 has crossed the right edge of air admission hole 27
During edge, AB working chambers are completely enclosed, and start compression travel, when the rotation 180 degree of three-apexed rotor 4 reaches position shown in accompanying drawing 7,
The volume of AB working chambers is minimum, and equivalent to the top dead center position of conventional engine, compression travel terminates, at this moment spark plug
Mixed gas is lighted in 54 arcings, starts expansion working stroke.Afterwards, when three-apexed rotor 4 rotates 270 degree, the appearance of AB working chambers
Product reaches maximum again, and equivalent to the bottom dead center position of conventional engine, expansion space stroke terminates.Then, such as the institute of accompanying drawing 8
Show, when the angle top B of three-apexed rotor 4 has turned over the left side edge of steam vent 28, AB working chambers are connected beginning with steam vent 28
Exhaust.Finally, when three-apexed rotor 4 is rotated by 360 °, AB working chambers are made to be returned to position shown in original accompanying drawing 4, so far AB works
Chamber completes a working cycles.At the same time, remaining two working chamber 7 also each completes a working cycles.
