Description

Firing engine

The present invention relates to a kind of firing engine, is a kind of novel rotary combustion engine that belongs in the heat engine field.

In prior art, the kind of internal-combustion engine is a lot, is divided into reciprocating type and rotary combustion engine according to its working principle with the different of structure.Reciprocating internal combustion engine commonly used because of reciprocating piston must be set, by connecting rod and bent axle with output power so complex structure, part are more, material requires height, amount of finish is big, also exist a series of technical barriers simultaneously.And rotary combustion engine is simple and compact for structure, easy processing, material requirements are low, external existing the development, and the power of rotary combustion engine that just is in the practical stage is also lower, according to some factory and R﹠D institution in China also in development test.In addition, various internal-combustion engines gas temperature in when work cylinder is all high, directly if the parts that contact with gas are untimely the cooling, then wherein can destroy matching gap or stuck because of the lubricating oil high-temp inefficacy behind the movement parts expanded by heating, each parts also Yin Gaowen cause mechanical strength to reduce or cause damage.And power and Economy are descended, so how to adopt suitable heat radiation cooling can make and send out the machine proper functioning also is the current problem that solves that needs to explore.

The purpose of this invention is to provide a kind of firing engine.It is a kind of any reciprocating parts such as piston, connecting rod, bent axle that are provided with, multi-cavity body rotor is only arranged, arbor is provided with air-inlet cavity, suction port, oil injecting nozzle, and what body was provided with detonation chamber, spark plug, relief opening only carries out parts suitably dispel the heat the burning gaseous fuel of cooling or the rotary combustion engine of the liquid fuel that is easy to vaporize.

The invention provides a kind of firing engine and be made up of body [1], rotor [2] and arbor [5] substantially, it is characterized in that: a, described body [1] are by interiorly having circular cylindrical cavity, tangent direction on a side to be provided with relief opening [8], being provided with the kettle shape housing of the bag shape detonation chamber [9] that 3 spark plugs [10] are installed at the rear of next-door neighbour's relief opening [8] sense of rotation; B, described rotor [2] are that both sides all have circular disc face, the circle elongation is connected with rotor hub [4] in one of them disc face, have more than three evenly five equilibrium and internal and external circumference be uncovered cavity cylindrical body between circular disc face at least, its back side is two spiral type curved surfaces to the radially partition between each cavity being streamline towards the direction of advance of rotating; C, described arbor [5] are to be fixed on that its excircle of body [1] center is smooth innerly for the rotation thereon of circle in rotor [2] and the rotor hub [4] be the cylindrical body of hollow, have suction port [6] in the rotor of a side [2] slewing area on cylindrical body, a middle oil injecting nozzle [7] that is equipped with in rotation the place ahead of contiguous suction port [6]; Be fixedly connected with gear ring [3] on d, described rotor hub [4] periphery.Its body [1] is to adopt up and down halved body or adopt cover that end double-body bike is fixedly connected to be synthesized, closely be installed with the lining [12] that has corresponding detonation chamber [9] and relief opening [8] access portal in the circular cylindrical cavity of being made in body [1] assembly parts after synthetic, on the inside circumference face at the lid and the end, be shaped on annular anti-attrition groove respectively.The bag shape outer side wall of its detonation chamber [9] is provided with some radiating fin [11].

The present invention compared with prior art, so it is not simple in structure, balance good, running is reliable, fault is less owing to there are movement parts such as reciprocating piston, connecting rod and bent axle, so be convenient to keep in repair, be beneficial to manufacturing.In addition, because of its multiple liquid fuel that can use gaseous fuel or be easy to vaporize, only need with air mixing the time, to be strict controlled in the lit range of detonation; Parts only adopt suitable heat radiation cooling, therefore its of many uses, good economy performance, and with low cost, expense is saved, is estimated that bright development prospect can be arranged.

An accompanying drawings specific embodiment of the present invention: accompanying drawing 1 is depicted as the internal-combustion engine main frame drawing in side sectional elevation of firing engine, and it has circular cylindrical cavity in forming or is made up of the lid ends two body with two halves amalgamation up and down by casting with common metal, be provided with relief opening [8] in the tangent direction of a side, be provided with a spark plug [10] at the rear of next-door neighbour's relief opening [8] sense of rotation bag shape is fired the body [1] of the kettle shape shelly of chamber [9].On detonation chamber [9] bag shape outer side wall, be provided with some radiating fin [11], in circular cylindrical cavity on the circle closely insert a steel lining [12] that has corresponding detonation chamber [9] and relief opening [8] access portal.The center fixation of body [1] has the arbor [5] of the cylindrical smooth interior hollow of a metal manufacturing, and the heart passes to its pressure and wants high low pressure charging fresh air than atmospheric pressure therein.In side rotor [a 2] slewing area of arbor [5], be provided with suction port [6], in the middle of the direction of advance of contiguous suction port [6], oil injecting nozzle [7] be housed, have input pressure a little more than the oil pipe of suction pressure also by passing through in the air-inlet cavity in the arbor [5].All there is circular disc face both sides, the circle elongation is connected with rotor hub [4] in disc face, is provided with eight even five equilibriums and internal and external circumference and is and roundly in the rotor hub [4] of the columniform cast rotor of uncovered cavity [2] by a circle and a side it in upward rotates, be fixedly connected with gear ring [3] at arbor [5] on the excircle of rotor hub [4] on the former face.Motor can start when being rotated by motor drives gear ring [3], rotor [2] is turned clockwise, in new gas drives in waste gas by upper right cavity relief opening [8], sweep substantially clean after, right cavity begins to enter new gas, the bottom right cavity is commencement of fuel injection then, all the other each cavitys are fuel oil (or combustion gas) and the new abundant mixing chamber of gas, its mixed proportion need be strict controlled in the lit range of detonation, until the top upper plenum can be lighted a fire by spark plug [10], the big cavity implode burning of forming in light a fire cavity and detonation chamber [9], promote rotor [2] and continue to turn clockwise along arbor [5], its power is exported by gear ring [3].Cold and hot state and the duration of runs length rotating speed of the igniting precedence of using three spark plugs during according to this internal combustion engine start just controlled adjustment.Initial and the final position of some data among the present invention such as suction port [6], oil injecting nozzle [7] wait further to carry out to determine after the test of many times apart from radian, porting flow area, detonation chamber [9] opening radian and volume, air-inlet cavity and exhaust cavity latus rectum size etc. with relief opening [8] apart from radian, suction port [6] with suction port [6].Component such as oil injecting nozzle of the present invention [7], oil pump, starting electrical machinery all can be selected for use when assembling and test voluntarily.
