Description

Automobile purifying apparatus

The utility model relates to the device that adds secondary air in the fuel-air mixture of motor car engine.

Automobile is when idling, and combustion ratio is very undesirable, and therefore giving off solid flue dust such as CO, HC exceeds NBS, causes serious atmospheric pollution.In order to address this problem, people have done effort from many aspects.A kind of method is that the bromine Oxygen Generator is installed, and uses in the bromine oxygen and CO, HC.Because the amount that adds is difficult for measuring, adding is too much very few all can to cause environmental pollution equally, so this method is unavailable.Other has some to add magnetic air, magnetization wet goods method, owing to there are many technical an open questions still, effect is undesirable.Chinese patent discloses the patent application that a key name is called the fuel-saving purification by-pass collar for No. 87205883, this device is equipped with an eddy current cover in the chamber of the connecting base that cooperates with the Carburetor and the suction tude of motor, the valve body inner conical cover of its connecting base one side is axially regulated snap and balance ring, and constitute two-way cone valve manifold with mitre velve and modulating valve are common, a negative pressure gate is arranged in the air-inlet cavity that the connecting base opposite side is extended, and be equipped with one vertically and be same as two-way cone valve manifold front half part, by the taper valve pocket, the unidirectional cone valve manifold that snap and mitre velve constitute, this device is because complex structure, sensitivity is not high, and is therefore not handy.

Task of the present utility model is: design a kind of automobile that makes and can keep rational combustion ratio when idling, make CO, HC in the air discharged below NBS, have simultaneously simple in structure, with low cost, long service life, easy to maintenance, purification plant that the fuel-saving efficiency that purifies air is high.

Task of the present utility model realizes as follows: be fastened with the tonifying Qi base plate with screw below automobile carburetor, be connected with the tonifying Qi box on it, with respect to the gas supplementing opening place control atmospheric pressure board is arranged in the tonifying Qi box, be connected with automatic adjustment spring on it, spring bearer plate, on the tonifying Qi box regulator is arranged, on the groove of the recessed garden of base plate, adjusting automatically has filtrating equipment in the spring.The through hole that is communicated with recessed garden groove and suction port is arranged in the tonifying Qi base plate.

Regulator on the above-mentioned said tonifying Qi box is that manual a benefit transferred screw.

The utility model so just can be followed the tracks of automatic adjustment combustion ratio owing to adopt adjustment spring adjusting air inflow automatically, makes automobile can keep reasonable combustion ratio under the idling situation, and the CO, the HC that make discharging reach the effect of purification, fuel-economizing below NBS.

Fig. 1 is the purifier sectional view;

Fig. 2 is the purifier plan view;

A most preferred embodiment of the present utility model, as figure, have recessed garden groove and suction port, connection garden groove and suction port above the tonifying Qi base plate 1 of purifier two through holes are arranged, be connected with tonifying Qi box 2 with screw above the tonifying Qi base plate, with respect to the gas supplementing opening place annular control atmospheric pressure board 7 in garden is arranged in the tonifying Qi box, the control atmospheric pressure board is by 3 controls of the automatic adjustment spring above it, above the spring 3 is spring bearer plate 8, spring bearer plate is transferred screw 4 controls by the manual benefit on the tonifying Qi box, on bottom plate groove, adjusting automatically has in the spring by the filtrating equipment 5 of screw on base plate.

Claims

1, a kind of automobile fuel saving purification plant, comprise that base plate, tonifying Qi box, of the present utility model being characterised in that in the tonifying Qi box have the control atmospheric pressure board with respect to the gas supplementing opening place, be connected with on it on automatic adjustment spring, spring bearer plate, the tonifying Qi box regulator is arranged, on the groove of the recessed garden of base plate, adjusting automatically has filtrating equipment in the spring.The through hole that is communicated with recessed garden groove and suction port is arranged in the tonifying Qi base plate.

2, purification plant as claimed in claim 1 is characterized in that the regulator on the said tonifying Qi box is that manual a benefit transferred screw.
