Description
Technical field
The novel explosive motor that relates to of this use, especially a kind of blade type diesel engine.
Background technique
Traditional piston type diesel engine, continuous acceleration-deceleration is wanted in the to-and-fro motion in cylinder of its piston, and this structure not only influences its mechanical efficiency, and vibrations are bigger.
At present, a kind of novel rotary polygonal piston engine appears.The same with reciprocating engine, rotary polygonal piston engine also is the pressure that utilizes air, fuel mixture burning to produce.Different is, in reciprocating engine, the pressure that burning produces is kept in the cylinder, order about piston motion, connecting rod and bent axle are converted to the to-and-fro motion of piston and rotatablely move, and in rotary engine, the pressure that burning produces is kept in the closed chamber that stator inner wall and triangular rotor (be used for replacing in this motor piston) constitute.Described rotary polygonal piston engine mainly comprises: the stator that inner chamber is substantially oblong-shaped, the top at each angle of three-apexed rotor---this three-apexed rotor contacts with the inwall slipper seal of described stator, the both sides of this three-apexed rotor contact with the two ends slipper seal of stator respectively, thereby constitute three independently sealed air chamber, the fuel supply system ignition system of unifying.Four parts of combustion process comprise: air inlet, compression, burning and exhaust.When rotor moves in stator, the volume of three air chambers that are made of rotor will change.This variation can produce a kind of pumping action.Air inlet: the circulation charging stage, in that time that suction port is connected air chamber, the volume of air chamber was near its minimum value when passing through suction port from rotor apex.When rotor turns over suction port, the volume of air chamber will increase, thereby air, fuel mixture are sucked air chamber.When the summit of air chamber during through suction port, this air chamber is promptly sealed, then and begin compression.Compression: when rotor continued to move in stator, it is littler that the volume of air chamber can become, and then pressurized air, fuel mixture, and when the face of rotor forwarded the spark plug place to, the volume of air chamber was once more near minimum, and this is the starting point of burning.Burning: when spark ignitor air, fuel mixture, can produce pressure rapidly, drive rotor motion, the pressure of burning can drive rotor and move along the direction that the air chamber volume increases, combustion gas continue to expand, and promote rotor and produce power, pass through relief opening once more until the summit of rotor.Exhaust: when the process relief opening of the summit of rotor, high-pressure combustion gas can be discharged in the venting gas appliance, when rotor continues motion, air chamber begins compression, forces remainder of exhaust gas to be discharged, when the air chamber volume near hour, the summit of rotor will be through suction port, and whole circulation begins once more.
This novel rotary polygonal piston engine is compared with traditional piston type diesel engine, has the following advantages: moving parts still less, thereby its reliability is higher; More smooth and easy, all parts all continue rotation along a direction in the rotary engine, do not need to change direction tempestuously the piston in conventional engines.But also there is following defective at present in this structure: the one, and thermodynamic efficiency is lower, and it is compared with reciprocating engine, and therefore the compression ratio of firing chamber is lower, than reciprocating engine oil consumption more, and can not make high power engine; The 2nd, the cost of production height, the structure more complicated of its three-apexed rotor is difficult for processing and assembling.Exactly because there are these defectives in it, cause rotary polygonal piston engine up to the present also not by popularization and application.
The model utility content
The novel purpose of this use is: a kind of thermodynamic efficiency height is provided, and cost of production is low, the blade type diesel engine of simple in structure and long service life.
