Abstract
The utility model discloses a purifying device for tail gas of a motorcycle engine, which comprises the motorcycle engine, a gas supply device, a muffler and a jetting device, wherein gas is supplied to the motorcycle engine by the gas supply device; the purifying device is characterized in that a gas supply pipe for supplying gas to the jetting device is arranged on the gas supply device; the jetting device comprises a gas inlet pipe, a negative pressure control valve, a check valve and a gas outlet pipe; the gas inlet pipe is connected with the gas supply pipe; and the gas outlet pipe is communicated with the muffler. The jetting device of the purifying device provided by the utility model is used for indirectly inputting fresh air into the muffler according to a working condition of the engine; under a high-temperature oxygen-rich condition, HC and NO in the muffler are oxidized and re-combusted; and the combustion efficiency of gasoline is increased, the combustion is more complete and the pollution to atmospheric environment is greatly reduced.
Description
Technical field
The utility model relates to a kind of motorcycle engine exhaust gas cleaner.
Background technique
At present national environmental protection portion to the motorcycle exhaust discharging require increasingly highly, and how the product of this low output value of motorcycle is made in control and is realized under the condition of cost that exhaust emissions reaches national requirements and becomes the target that each main frame producer is pursued.The effective way that can efficiently realize this target at present is to adopt electric injection system, catalyst three-element catalytic technology.
Chinese patent CN200720125187.3 discloses the automatically controlled air washer of a kind of motorcycle, and it adjusts the aperture of solenoid valve by electronic controller according to the tach signal of motor, promptly controls the air mass flow through solenoid valve, to realize the dynamic adjustments air compensation.Yet though this solenoid valve helps precisely controlling the air inlet opportunity of secondary air, its cost is higher relatively also.
In addition, catalyst three-element catalytic technology is to install the catalyzed conversion agent additional in the silencing apparatus the inside, and its defective is that the cost increase is very high, and working life is limited.
The model utility content
The purpose of the utility model is the deficiency to existing technology, and a kind of motorcycle engine exhaust gas cleaner with bowel relaxing functions is provided.
For achieving the above object, the utility model adopts following technological scheme to realize:
The motorcycle engine exhaust gas cleaner comprises motorcycle engine, to the air feeder of this motor air feed; Silencing apparatus and injection apparatus; Said air feeder is provided with the air supply pipe to said injection apparatus air feed, and said injection apparatus comprises suction tude, negative pressure control valve, one-way valve and steam outlet pipe, and said suction tude is connected in said air supply pipe; Air in the said air supply pipe is got into by suction tude, is delivered in the silencing apparatus through negative pressure control valve, one-way valve and steam outlet pipe.
Further, said motor comprises cylinder head, the air supply passage that is provided with gas-entered passageway, the exhaust passage that is connected with silencing apparatus in this cylinder head and is connected with said steam outlet pipe, and this air supply passage is connected in said exhaust passage.
Further, injection apparatus comprises the negative pressure pipe, and this negative pressure pipe is connected to the gas-entered passageway of said cylinder head.
Further, said air feeder comprises the sky filter.
The beneficial effect of the utility model is: be input to fresh air in the silencing apparatus indirectly through injection apparatus according to engine operating condition; Under high-temperature oxygen-enriched condition; HC in the silencing apparatus and NO are realized oxidation and burning again; Improve the combustion efficiency of gasoline, make burning more abundant, significantly reduced pollution atmosphere environment.
Description of drawings
Fig. 1 is the structural representation of the said motorcycle engine exhaust gas cleaner of the utility model.
Embodiment
For structure, characteristic and effect thereof to the utility model, can have and further understand and be familiar with, lift a preferred embodiment at present, and be described with reference to the accompanying drawings as follows:
As shown in Figure 1, the described motorcycle engine exhaust gas cleaner of the utility model comprises motorcycle engine 1, to the air feeder 2 of this motor air feed, and silencing apparatus 3 and injection apparatus 4, institute's air feeder 2 comprises the empty filter 21 of filtered air.Said air feeder 2 be provided with to said injection adorn 4 put air feed air supply pipe 22, said injection apparatus 22 comprises suction tude 41, negative pressure control valve, one-way valve and steam outlet pipe 42, said suction tude 41 is connected in said air supply pipe 22.
As shown in Figure 1, said motor 1 comprises cylinder head 11, exhaust passage 112 that be provided with gas-entered passageway 111 in this cylinder head, is connected and the air supply passage 113 that is connected with said steam outlet pipe 42 with silencing apparatus, and this air supply passage 113 is connected in said exhaust passage 112.
Further, injection apparatus comprises negative pressure pipe 43, and this negative pressure pipe 43 is connected to the gas-entered passageway 111 of said cylinder head 1, controls the switch motion of the valve of this negative pressure control valve to import negative pressure.But the one-way valve air only flows to the silencing apparatus direction.
During use, the oil gas that gets into suction tude by motorcycle carburetor makes in the negative pressure pipe and produces negative pressure, when negative pressure value reaches one regularly; Negative pressure control valve is opened, and sucks air, and air sucks injection apparatus 4 by empty filter 21; One-way valve through injection apparatus 4 gets into air supply passage 113 through steam outlet pipe, and 112 get into silencing apparatus 3 through the exhaust passage, thereby in silencing apparatus 3, replenish fresh air; And utilize high temperature to burn again, discharge tail gas is effectively reduced.
The above is merely the preferred embodiment of the utility model; It is not the practical range that limits the utility model with this; Allly be familiar with this operator; The principle and the technical characteristics of utilization the utility model, various changes and the decoration done all should be covered by within the protection category that these claims define.
