Abstract

The utility model relates to a direct rotary combustion engine, which belongs to the manufacture of combustion engines which provides a combustion engine works in a directly rotating mode according to the working principle of combustion engines. The utility model is characterized in that through the combustion working process of an elliptical working chamber which is formed between more than two upper halt elliptical cavities which are uniformly distributed on the inner side of a stator body and a plurality of lower elliptical cavities which are arranged on the periphery along the surface of the outer body of the rotor body. Owing to the characteristics, the utility model is a combustion engine which has the advantages of simple structure, easy manufacture and low loss and the performance of the utility model can be used for the fields, such as automobiles, etc.

Description

Direct rotary combustion engine

The utility model belongs to the internal-combustion engine manufacturing.

Since the seventies in 18th century, that is from steam engine has been arranged, just have many Designers and inventor seeking a kind of structural type always---inflation process is directly become the rotary engine that rotatablely moves by internal compression, in the hope of the to-and-fro motion in the cancellation conventional engine, make motor to higher rotating speed development.Wankel RC configuration is considered to the most successful a kind of rotary piston machine at present in the prior art.But the idling of this motor is less stable also, and the hypervelocity phenomenon easily takes place when bottom gear or gearshift, easily forms the shake line at the cylinder face.Require in the modern times under the situation of low blowdown and low fuel consumption, Wankel engine will be obtained strong competitive position, must further improve and perfect.The utility model has been exempted some defectives that exist owing to structurally have unique advantage and it is simplified in other motor, fuel can more be made full use of, and also have good reliability, stability, therefore have more actual application value.

The purpose of this utility model, there is the structure relative complex in the cylinder piston type motor that has been to overcome present extensive use, factors such as manufacture process requirement height, use direct rotation mode, provide a kind of simple in structure, stable work in work, the internal combustion engine that manufacturing is more convenient.

For achieving the above object, the utility model has adopted directly to promote the working method of rotor rotation after the fuel combustion.It is a foundation with the internal combustion engine principle, its structure is divided into rotor, rotor body two-part, by the plural upside of ellipse cavity of equiblibrium mass distribution in the rotor inner side surface, and be arranged in the burning working procedure of the oval working room that constitutes between several second oval cavity in one week of rotor body outer face, directly make rotor rotation produce the torsional moment acting.

Advantage of the present utility model is to adopt direct rotation mode, compares with existing reciprocating engine, does not have reciprocating mass and exhaust valve, and volume is little, and is simple in structure, easily processing, and speed can further improve, the long fuel availability height of combustion stroke.Owing to be directly to rotate periodic duty, so air inlet, igniting can be worked under higher frequency.Plural operation point balanced operation makes and operates steadily reliably.Motor directly rotates acting, has avoided as reciprocating engine, needs to produce the energy loss that surface friction drag causes through transmission repeatedly.Reciprocating engine because the torsional vibration of engine shaft system causes the loss of energy, also causes to a certain extent component is damaged when work simultaneously.Directly rotaryly then exempted this and kept away end.Its designs simplification of this motor, thereby give to make processing and bring convenience compares with reciprocating engine that processing technology is relative to be required lowly, simultaneously manufacture cost is greatly reduced, and makes to make to produce to become more easy.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof

Fig. 1 is the grown form schematic diagram of Direct rotating type motor; Fig. 2 has increased a upside of ellipse cavity and air advances snifting valve under the groundwork state; Fig. 3 is by a plurality of direct rotary engine monomers and connects and be combined into cluster engine.

Fig. 1 has provided the grown form of direct rotary combustion engine.Its structure is divided into stator, rotor body two-part.At the first half of rotor inner side surface (can according to the practical use difference of motor) journey equiblibrium mass distribution oval cavity more than two (among Fig. 1 1.).At the Lower Half of making several oval cavitys of arranging with certain inclination angle in one week of rotor body outer face (among Fig. 1 2.).Upside of ellipse cavity in the rotor forms the oval cavity (among Fig. 1 1.) of a complete closure with arbitrary second elliptic cavity body in the rotor body.In first cavity of stator, install spark plug, advance snifting valve (among Fig. 1 3. 4.).After the air inlet igniting, fuel expands to promote second cavity (rotor body) rotation in the cavity internal combustion, and the dilation gas along with gas enters the next one simultaneously, and is next again ... half cavity continues acting, is discharged from (among Fig. 1 5.) with the end gas of burning.Form the overall process of one stroke like this.If on rotor, increase in the upside of ellipse cavity system one advance snifting valve (among Fig. 2 6.) through air inlet light start working after, pour air again and make that burning is more abundant, fuel availability is higher, exhaust is more cleaned.With regard to motor generally speaking, simultaneously with correspondent frequency air inlet, igniting, promote the motor smooth running in the plural upside of ellipse cavity.By the adjustment to air inlet state, ignition frequency, it can reach the effect similar to direct current motor substantially.Adopt a plurality of motor monomers on this basis and connect and form cluster engine (as Fig. 3), with further raising engine power.

The utility model can be widely used in the fields such as automobile owing to have good economy, If accessing as early as possible, development and use will produce very positive social effect.
