Description
Technical field
The present invention relates to field of power machinery, igniting for rotary engine field, more particularly to a kind of rotary engine is logical
Road.
Background technology
The development of economic and automobile industry, snafu change is brought to our life.Engine is used as automobile
Core component, though from aspect of performance or its discharge effect on environment degree, all have strict requirements to engine.
Rotary engine has that simple in construction, power to weight ratio is high, fortune compared to conventional reciprocating formula engine as a kind of new engine
The advantages of turning steady.Therefore, rotary engine is by extraneous attention rate also more and more higher.
But the special motion mode of rotary engine makes it that following two features are presented：First, cylinder interior air-flow be with
The motion of rotor rotation direction, that is to say, that the air-flow of combustion chamber is in lack change in one-way flow, cylinder acutely on the whole
Vortex and tumble flow.Second, long and narrow chamber structure causes the air-flow velocity near time of ignition spark plug very big.
Two more than rotary engine features can cause to face three below defect in its course of work：Firstth, spark
Flow velocity near plug is too high so that ignition energy is easy to be taken away by high velocity air, and the lost of ignition energy can further cause a little
Fire is not easy success.In order to improve the stability of igniting, igniting success is set to come more, it is necessary to install more powerful ignition system
Mend, this will increase the cost of engine.Secondth, the characteristics of unidirectional stream being presented due to cylinder interior air-flow, and this unidirectionally flows
Direction is to flow to combustor head from combustion chamber rear portion, and this results in the flame after lighting a fire successfully and is easy to be brought towards combustion chamber
It is anterior, it is impossible to maintain near spark plug.This will be such that the fuel of combustion chamber postmedian is not ignited in time, imperfect combustion
Increase the unburned hydrocarbon content in emission.3rd, the fuel relatively low to some volatility, such as heavy oil, aviation kerosine, due to
Lack in the volatility difference and cylinder of fuel and change violent vortex and tumble flow, this makes to be difficult to form flammable mixing near spark plug
Gas, so results in that fuel is more difficult to be ignited, and burns also more unstable.The above defect all makes rotary engine
Efficiency of combustion reduces and discharges exceeded, and also exactly these disadvantages described above make rotary engine without the traditional reciprocating engine of the image of Buddha
Machine is used widely like that, is also rooted in the hearts of the people like that without image of Buddha reciprocating engine.
In addition, rotary engine is in the running, three-apexed rotor can be contacted in rotation process with cylinder face, and this is required
Not so the spark plug installed can cause the collision of rotor and spark plug not above cylinder face.Therefore, spark plug and combustion
It is to be connected by one section of passage not occupied by spark plug between burning room.Traditional spark plug passage is all circular channel, this circle
The passage of shape realizes the connection of spark plug and combustion chamber really.But this circular passage has two sides the problem of bring
Face：First, the air-flow in combustion chamber is not easily accessed the circular channel, and this, which is resulted in, can not form enough concentration near spark plug
Gaseous mixture and be difficult to light a fire successfully.Second, the wall surface temperature of circular channel is not high, and this is difficult to the liquid fuel that volatilizees to some
Igniting be very unfavorable.Because：, also can be because even if the droplet after liquid fuel atomization has been entered in the passage
Make fuel be attached on wall to be difficult to volatilize for wall surface temperature is low, so as to cause fuel can not form combustion mixture in time.
In summary, the special working method of rotary engine result in the ignition difficulties of its cylinder fuel, and light a fire
Flame easily moves to combustor head and causes combustion chamber postmedian fuel not burn timely afterwards.In addition, rotor starts
Machine in the running, to avoid rotor from being collided with spark plug, is not occupied between spark plug and combustion chamber by one section by spark plug
Passage is connected.And traditional circular spark plug passage is unfavorable for air-flow into the passage, and it is unfavorable for the rapid evaporation of fuel.
This has been further exacerbated by rotary engine ignition difficulties and the low defect of efficiency of combustion.
