Abstract

The utility model relates to an oil saving device for an engine. The utility model is composed of a housing, flow guiding blades, and a shaft core. The utility model is processed in injection molding by high temperature resisting engineering plastics. A plurality of flow guiding blades with an inclined surface, which are arranged in the utility model, are extended from the shaft core to the housing with an outer diameter and are connected as a whole, and the flow guiding blades which have the same angle and the same direction form a helical shape in centripetal uniform arrangement. Through the utility model, adjusting the inflow capacity of the air in a right amount according to the actual demand of the running of the engine can be realized, and the mixed atomization of fuel oil and the air is more ideal and more uniform. Therefore, the power performance of the engine is improved, fuel oil consumption is reduced, and the exhaust level of harmful exhaust gas is reduced.

Description

Engine economizer

The utility model relates to a kind of fuel economizer of motor.

The most nature suction air methods that adopt of motor are burnt, fail to regulate its air mass flow in right amount according to the engine running actual demand, cause easily and start difficulty, quicken not smooth, particularly in winter during starting a cold engine, have only the chock plate in the pull-up Carburetor to reduce the air influx, increase the concentration of inflammable mixture, just can make motor start operation smoothly.

The purpose of this utility model provides a kind of engine economizer.It can regulate the air influx in right amount according to the real-world operation state of motor, and can form the air swirl along Carburetor air intake or engine charge pipeline axis high speed rotating when high engine speeds turns round.Make fuel oil and air mixing atomize betterly, average, also can increase the intake of inflammable gas in the cylinder simultaneously.

The purpose of this utility model is achieved in that a kind of engine economizer.Form by shell, guide vane, axle core.Fuel economizer is extended and is linked to be whole inclined-plane guide vane to the external diameter housing by the axle core by several and constitutes, and its angle and direction is identical, and entad evenly distributed curl; In each blade, be provided with several air holes.It is fixedly installed on the carburetor air mouth or in the engine charge pipeline.When time of engine low speed or starting a cold engine, because of the guide vane in the fuel economizer flows into air certain drag effect is arranged, so just can play the function of chock plate, thereby reduced the air influx in right amount, increase the concentration of inflammable mixture, it is easier that it is lighted in cylinder, so that motor normally starts operation; In addition when high engine speeds turns round, a large amount of air enter Carburetor or engine charge conduit by the fuel economizer guide vane at a high speed, because of guide vane has certain disturbance to air ventilation, its air hole can produce the air turbulence effect again, thereby has changed original airflow direction---form one air swirl along Carburetor or admission line axis high speed rotating.Because the effect of inertia of swirling eddy will cause air velocity quickening, flow to increase, and also can produce certain air-flow inertial pressure.

The utility model contrast prior art has following advantage: because the effect of fuel economizer guide vane, not only can make motor regulate the air influx in right amount according to the running actual demand---when low-speed running, suitably improve the concentration of inflammable mixture, be convenient to its easier lighting in cylinder; When running up, can improve the mixed proportion of air and fuel oil again, also can increase the intake of cylinder combustion gas.And make fuel oil and air mixing atomize betterly, average, thereby make in the engine cylinder burning more completely.Its torsional moment is increased, and power character is further improved, and vehicle quickens more convenient.Also can reduce the emission level of fuel consumption and harmful exhaust simultaneously.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the plan view of Fig. 1;

Fig. 3, the 4th, the plan view of Fig. 1, worm's eye view.

In Fig. 1, fuel economizer is provided with six and is extended and be linked to be whole inclined-plane guide vane (2) to external diameter housing (1) by axle core (3), and its angle and direction is identical, and entad evenly distributed curl; Can see in fuel economizer external diameter housing (1) bottom referring to Fig. 2, Fig. 4 and to be provided with the usefulness that four sheet support foots are used for installing and locating: among each guide vane (2), be provided with the air hole (4) of three long strips in addition as seen from Figure 3, be used to produce the air turbulence effect.When the air low-speed flow through fuel economizer guide vane (2) when entering carburetor inlet, thereby can run into certain resistance---reduced the influx of air in right amount, also just played the function of chock plate; If when air a large amount of during at a high speed by fuel economizer guide vane (2)---because of guide vane (2) has certain disturbance to air ventilation, so changed original airflow direction, formation is along the air swirl of carburetor inlet axis high speed rotating.Big more its revolving ability of flow, flow velocity is also just corresponding strong more.

This fuel economizer adopts thermostability engineering plastic injection moulding machine shaping.The quantity of guide vane (2) can be provided with according to the fuel economizer diameter; The sheet support foot is looked its mounting point and is determined to set up---and not essential.

Claims

A kind of engine economizer is characterized in that: fuel economizer is extended and is linked to be whole inclined-plane guide vane (2) to external diameter housing (1) by axle core (3) by several and constitutes, and its angle and direction is identical, and entad evenly distributed curl; In each blade (2), be provided with several air holes (4).
