Abstract
The utility model discloses an energy-saving device for electrically adjusting the idle speed of an electronic fuel injection engine, which is composed of an air filter and an adjusting valve. The air filter is communicated with an inlet port of the adjusting valve, and an outlet port of the adjusting valve is communicated with an inlet pipe of the electronic fuel injection engine. The adjusting valve is provided with a straight-through pipe on which a through hole perpendicular to the axis of the straight-through pipe is arranged; a rotatable valve rod is inserted in the through hole, and the valve body is provided with a valve hole perpendicular to the axis of the valve rod; the valve hole is communicated with the straight-through pipe; one end of the valve rod extends out of the straight-through pipe and is connected with a speed reducing motor which can drive the valve rod to rotate; the speed reducing motor is electrically connected with an automobile power supply through a switch; the speed reducing motor drives the valve rod to rotate to change the relative connectivity of the valve hole of the valve rod and the straight-through pipe so as to adjust the air inlet amount. When the air inlet amount is small, the idle speed of the electronic engine is reduced, and the consumption of fuel oil is saved. The utility model is convenient for operation, has accurate adjusting accuracy of the air inlet amount, and low failure rate.
Description
Technical field
The utility model relates to a kind of economizer, particularly a kind of economizer of motorized adjustment electronic fuel injection engine idling.
Background technique
Discharging and the raising efficiency of engine of existing automobile in order to reduce tail gas generally all used electronic fuel injection engine, and this electronic fuel injection engine is not used Carburetor, and by size to firing chamber in the electronic oil spout of microcomputer control according to air inflow.When the electronic fuel injection engine idling is rotated, the too high easy waste fuel oil of idling.A kind of device of controlling the electronic fuel injection engine idling occurred is economizer for this reason, as shown in Figure 2, this device is by air-strainer 1, regulating valve 2 constitutes, air-strainer 2 is communicated with the suction port 21 of regulating valve 2, the air outlet 22 of regulating valve 2 is communicated with the suction tude of electronic fuel injection engine, the structure of regulating valve 2 is, has a straight-through tube 3, offer a through hole 31 perpendicular to the axle center on the straight-through tube 3, be plugged with valve rod 4 in this through hole 31, this valve rod 4 offers the valve opening 41 perpendicular to valve rod 4 axle center, this valve opening 41 can be communicated with straight-through tube 3, two ends of valve rod 4 stretch out outside the straight-through tube 3, sheathed spring 5 between one termination of valve rod 4 and the straight-through tube 3, valve rod 4 the other ends are connected with a backguy 6, pulling backguy 6 moves up and down valve rod 4 in the through hole 31 of straight-through tube 3, the valve opening 41 of valve rod 4 is changed with the amount of connection of straight-through tube 3, and then adjusting air inflow, air inflow hour, the idling of electronic fuel injection engine reduces, saved the consumption of fuel oil, after unclamping backguy 6, valve rod 4 restPoses under the effect of spring 5.The shortcoming of the existence of this device is, uses the idling air inflow of manual tune electronic fuel injection engine, and degree of regulation is lower, and the manual tune inconvenient operation also easily breaks down sometimes and can't work.
Summary of the invention
The purpose of this utility model is the lower problem of manual tune inconvenient operation, degree of regulation that exists for the device that overcomes above-mentioned control electronic fuel injection engine idling, and a kind of economizer of easy to operate, motorized adjustment electronic fuel injection engine idling that degree of regulation is more accurate is provided.
The utility model is by air-strainer, regulating valve constitutes, air-strainer is communicated with the suction port of regulating valve, the air outlet of regulating valve is communicated with the suction tude of electronic fuel injection engine, the structure of regulating valve is, has a straight-through tube, offer a through hole perpendicular to the axle center on the straight-through tube, be plugged with rotary valve rod in this through hole, this valve rod offers the valve opening perpendicular to the valve rod axle center, this valve opening is communicated with straight-through tube, one end of valve rod stretches out the straight-through tube loong shunt to be tied a reducing motor and can drive valve rod and rotate, and this reducing motor is electrically connected with automobile power source by a switch.
Working principle of the present utility model is:
Reducing motor drives valve rod and rotates, and the valve opening of valve rod is changed with the relative connection amount of straight-through tube, and then regulates air inflow, air inflow hour, the idling reduction of electronic fuel injection engine, the consumption of having saved fuel oil.
The beneficial effects of the utility model are:
1, by the idling air inflow of reducing motor motorized adjustment electronic fuel injection engine, easy to operate, the degree of regulation of air inflow is more accurate.
2, rate of fault is low.

Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is the structural representation of the device of existing control electronic fuel injection engine idling.
Embodiment
See also shown in Figure 1, be embodiment of the present utility model, be by air-strainer 1, regulating valve 2 constitutes, air-strainer 2 is communicated with the suction port 21 of regulating valve 2, the air outlet 22 of regulating valve 2 is communicated with the suction tude of electronic fuel injection engine, the structure of regulating valve 2 is, has a straight-through tube 3, offer a through hole 31 perpendicular to the axle center on the straight-through tube 3, be plugged with rotary valve rod 4 in this through hole 31, this valve rod 4 offers the valve opening 41 perpendicular to valve rod 4 axle center, this valve opening 41 is communicated with straight-through tube 3, one end of valve rod 4 stretches out straight-through tube 3 loong shunts to be tied a reducing motor 7 and can drive valve rod 4 and rotate, and this reducing motor 7 is electrically connected with automobile power source by a switch 8.
The working principle of present embodiment is:
Reducing motor 7 drives valve rods 4 and rotates, and the valve opening 41 of valve rod 4 is changed with the relative connection amount of straight-through tube 3, and then regulates air inflow, air inflow hour, the idling reduction of electronic fuel injection engine, the consumption of having saved fuel oil.
