Abstract

The utility model relates to an auxiliary oxygen increasing and air supplying pressure booster which is characterized in that an air supply port, a filter screen, a filter cavity and an air inlet are connected in series, wherein one end of the air inlet is arranged in an atomization cavity, and the left lower side of the atomization cavity is connected with the air inlet; the inner diameter of the air inlet is 8 cm, and the air inlet is communicated with the atomization cavity; the inner diameter of the air supply port is 0.3 mm, and the air supply port is communicated with the atomization cavity simultaneously. When an air inlet door is opened, under the suction of an engine, the air inlet enters the main body of a fuel economizer through clean air from an air filter because the mass of air is lighter than that of gasoline, and then enters an air inlet hollow throat through the air supply pipe of 0.3 mm after being filtered once more by the filter cavity and the filter screen, so that the air inlet enters a combustion chamber in advance; and secondly, secondary atomized and mixed gas in the auxiliary oxygen increasing and air supplying pressure booster enters a cylinder for increasing pressure and supplying air, so as to improve the air change efficiency and promote combustion, so that the aims for increasing the engine efficiency, reducing the tail gas emission, and prolonging the service life of the engine are achieved.

Description

Auxiliary oxygenation air-admission pressure-booster

Technical field

The utility model relates to a kind of Motor Vehicle gas handling system, is a kind of auxiliary oxygenation air-admission pressure-booster concretely.

Technical background

At present, motorcycle generally adopts the overwhelming majority that accounted for of Carburetor fuel feeding, this mechanism simple structure, easy to maintenance, but there is obvious deficiency: as the carburetor type four stroke engine, 720 ° of four strokes finishing motor of crankshaft rotating, i.e. air inlet, compression, work done, exhaust.And conventional carburetor formula four-stroke gasoline engine, when piston is moved toward lower dead center by top dead center, intake valve is opened, air stream drinks up the gasoline of Carburetor the inside and air formation mixed gas in the time of Carburetor, be drawn onto in the cylinder and burn, but four stroke engine based on Carburetor, because the major defect of Carburetor is to have inadequate natural endowment on itself working principle, Carburetor is the negative pressure that relies on the formed certain value of air flows in the suction tude, fuel oil or foam-like fuel oil and Air mixing aspiration are gone into engine cylinder, be subjected to the influence of throttle inflow stream, make Carburetor in the overall process of engine operation, be under the negative pressure state always and move.Therefore, this has just determined that also Carburetor can not obtain more satisfactory air inflow.Under engine idle and medium and small load condition, because the air quantity of demand is limited, but require to obtain wellatomized mixed gas, at this moment, the closure throttling action is remarkable, and this certainly will cause the mixed gas overrich that forms through Carburetor, and general air fuel ratio is all below 10: 1, form easily admission line inwall oil film, make that engine combustion is insufficient, power descends, engine life is short, discharging exceeds standard, especially HC is for very.

The model utility content

The purpose of this utility model is to provide a kind of auxiliary oxygenation air-admission pressure-booster, make guaranteeing former Carburetor fuel feeding simple structure on the basis easy to maintenance, also to have the reduction oil consumption, prolong motor working life, can be used as the auxiliary oxygenation air-admission pressure-booster of the oil supply system of motorcycle.The utility model is realized with following technological scheme: gas supplementing opening, filter screen, filtering cavity, suction port series connection, one end of suction port is installed in the inside of atomizing cavity, the left bottom of atomizing cavity connects suction port, the internal diameter 8cm of suction port, and communicate with atomizing cavity, the internal diameter 0.3mm of gas supplementing opening communicates with atomizing cavity and suction port simultaneously.Install after the auxiliary oxygenation air-admission pressure-booster, when the four stroke engine piston moves from top dead center toward lower dead center, intake valve is opened, the gasoline that is drunk up in air and the Carburetor forms mixed gas and is drawn onto in the cylinder, the air of auxiliary oxygenation air-admission pressure-booster the inside also is drawn onto in the cylinder by piston, when piston is moved toward top dead center by lower dead center, IC Intake Valve Closes, auxiliary oxygenation air-admission pressure-booster the inside produces vacuum, under action of pressure, the gasoline of Carburetor the inside is drunk up with air formation mixed gas is compressed to auxiliary oxygenation air-admission pressure-booster the inside, forms the inflammable mixture of primary atomization.When intake valve is opened, under the suction of motor, because of the quality of air is lighter than gasoline, the cleaned air that suction port is come by air-strainer enters the main body of fuel economizer, after process filter chamber and filter screen filter once more, gas supplementing opening by 0.3mm enters the air inlet trunnion, does sth. before others have a chance to and enters the firing chamber; Secondary-atomizing mixed gas in the secondly auxiliary oxygenation air-admission pressure-booster enters cylinder and carries out super charge, strengthens scavenging efficiency, promotes burning, increases engine power, reduces exhaust emissions and prolongs the motor purpose in working life thereby reach.

Compared with the prior art, use this auxiliary oxygenation air-admission pressure-booster can solve the Carburetor atomization badness, the oil consumption that causes is big, and drawback such as be short of power.

In sum, just because of this auxiliary oxygenation air-admission pressure-booster has the Carburetor of solution atomization badness, the oil consumption that causes is big, the function that is short of power, thus prolong motor working life and save fuel oil.
