Abstract

The utility model relates to an evenly-mixed oxygen activating device for an automotive internal combustion engine, comprising a thin-shell guide flow barrel which is communicated with a mixed gas chamber of the internal combustion engine, a throttle valve and a mixed gas inlet main duct of the internal combustion engine, and the internal diameter of the thin-shell guide flow barrel is equal to or smaller than the mixed gas inlet main duct of the internal combustion engine. An internal wall of the guide flow barrel is connected with a rotatable impeller through a transversal bracket which is connected fixedly. An oxygen active layer with li 2 O are coated separately on the internal wall of the guide flow barrel, the transversal bracket and blades of the impeller.

Description

The mixing that car combustion engine is used-oxygen activated device

The utility model relates to a kind of device that makes condensed fuel atomize or the fuel air mixture homogenizing is used, and especially has the mixing-oxygen activated device of rotary component, can make the fuel air mixture homogenizing.

After air and fuel mix, enter mixed gas air inlet common excretory duct from mixed air vessel through closure, be redistributed to each cylinder, car combustion engine mixed air vessel commonly used, closure, mixed gas common excretory duct though adopted the higher Carburetor of fogging degree, but still exist specific fuel consumption big to cylinder, the incomplete combustion of fuel, CO in the waste gas, the problem that HC content is very high, this point can be from the electronics rotational speed meters to being confirmed the existing car combustion engine detecting rotational speed.Trace it to its cause, when being idle running higher this factor of mixture strength, to be that mixed gas is inhomogeneous cause prior reason, the cylinder that has has entered rich mixture, and the mixture strength that the cylinder that has enters is rare excessively, makes the rich mixture incomplete combustion, wasted more fuel, cross rare mixed gas and misfire and also wasted fuel, each cylinder has produced evident difference to the pressure of bent axle simultaneously, so cause the nonuniformity of internal-combustion engine rotational speed.

The purpose of this utility model is to propose mixing-oxygen activated device that a kind of car combustion engine is used, and it is arranged on oil nozzle to internal-combustion engine and advances in the section in the mixed gas common excretory duct.Fuel and air Mixture are mixed fully, make the mixture strength that is assigned in each cylinder even, thereby guarantee the stability of internal combustion engine.

Another purpose of the present utility model is the binding ability that improves oxygen and hydrocarbon substance, makes fuel obtain perfect combustion, thereby makes CO in the waste gas, HC and No _xContent reduce more than 50%.

Model utility is achieved in that mixing-oxygen activated device that a kind of car combustion engine is used, comprise and advance with internal-combustion engine mixed air vessel, closure IV, internal-combustion engine that mixed gas common excretory duct III is communicated with and internal diameter is equal to or less than the shell guide shell 2 that internal-combustion engine advances mixed gas common excretory duct III, it is characterized in that: the inwall at guide shell 2 is connected with a rotatable impeller G by affixed horizontal support 3; Coating material is Li respectively on the blade 6 of the inwall of described guide shell, horizontal support, impeller ₂The oxygen activated layer 8 of O.Rotatable impeller is the assembly parts G that is installed in vertical shaft 4 and blade 6 on the bearing 5.Bearing 5 is fixed with horizontal support 3, apply oxygen activated layer 8 for be coated with or one deck Li that bonds ₂The oxygen activated layer of O.

The utility model makes each working cylinder all obtain uniform mixed gas and guarantees full combustion of fuel, makes pollutant CO, HC and NO in the exhaust gas of internal combustion engines _xReduce more than 50%.

Now further narrate structure of the present utility model in conjunction with the accompanying drawings:

Referring to Fig. 1, Fig. 2: advance mixed air vessel's outlet flange disc I in the mixed gas common excretory duct at car combustion engine oil nozzle to internal-combustion engine, advance in the section that mixed gas common excretory duct flange disc II and internal-combustion engine advance mixed gas common excretory duct III the utility model is installed, allow mixed gas just can enter each cylinder arm, arrive cylinder then through rotatable impeller G.

Advance the identical or slightly little shell guide shell 2 of mixed gas common excretory duct III internal diameter with internal-combustion engine and communicate with closure IV, guide shell flange disc 1 is between mixed air vessel outlet flange disc I and advance between the mixed gas common excretory duct flange disc II.At guide shell near the center with screw or with the affixed horizontal support 3 of Bond, the affixed vertical shaft 4 at the center of horizontal support, bearing 5 is inserted in the vertical shaft top, blade 6 is installed around bearing, blade 6 is combined to form impeller G with bearing 5 or blade 6 with vertical shaft 4, blade is with metal or nonmetal making, the turning radius of blade 6 is less than the radius of guide shell 2, the shape of blade can be a rectangle, oval or circular, a safety helmet 7 is installed above bearing, and the radius of the vertical shaft radius ratio bearing of bearing 5 bottoms is big, to support impeller G.The angle that blade 6 and mixed airflow flow to is greater than zero degree, if with vertical shaft during as running shaft, blade 6 can be directly installed on the vertical shaft, at this moment, bearing will be installed in the center portion of support, then vertical shaft 4 is positioned in the bearing, can be arranged in the bearing of a support 3 having 2 or 2 vertical shafts 4 with upper blade 6, and on blade 6, guide shell inwall 2 is coated with one deck or with Bond bonding one deck Li on the support 3 ₂The oxygen activated layer 8 of O.When mixed airflow touches impeller G, because angle＞0 of blade 6 and airflow direction °, air-flow has produced torsion or thrust on blade 6, under the moment loading that air-flow produces, place the bearing 5 on the vertical shaft 4 to rotate, the speed of air-flow is higher, and impeller G rotates soon more, and the space between space between blade and the blade and blade and the guide shell inwall is exactly the place that air communication is crossed.When mixed airflow promotes impeller G high speed rotating takes place, under action of centrifugal force, with mixed airflow from the guide shell center fall to around on the inwall, advance mixed gas common excretory duct III from internal-combustion engine then and enter cylinder.At this moment, the mixed gas that fuel and air form mixes fully, and the concentration that just is assigned to the mixed gas of each cylinder is uniformly, and the thrust that mixture combustion produces is identical.So also just guaranteed the stability of internal combustion engine.When mixed gas touches oxygen activated layer bonding on the inwall, support 3 of blade 6, guide shell 28, the outer shell electron of oxygen is excited and increased in conjunction with gesture, this binding ability that has improved oxygen and hydrocarbon substance in conjunction with gesture greatly, guaranteed the perfect combustion of fuel thus, and made CO in the waste gas, HC and NO _xContent reduce more than 50%.
