The engine of the utility model can reduce the content of carbon monoxide, hydrocarbon and oxynitride in the exhausted waste gas.
Description
(1). technical field
The utility model relates to a kind of fuel engine, particularly a kind of motor that can make waste gas circulation and burn once more of air injection reaction.
(2). background technique
At present, general fuel engine is that fuel oil and air mixing are burnt in the firing chamber, the control of its burning back toxic emission, main dependence installed the content that three-way catalyst reduces CO, hydrocarbon, oxynitrides, but its cost is higher, and catalyzer loses catalysis easily by the lead pollution in the gasoline.
(3) summary of the invention
The purpose of this utility model provides a kind of air injection reaction and exhaust gas recirculation motor, and it can make the content of CO in the engine emission waste gas, hydrocarbon, oxynitrides reduce, and reduces the pollution of toxic emission to environment.
For reaching above-mentioned purpose, air-strainer of the present utility model is communicated with the suction tude of cylinder head by Carburetor, cylinder head exhaust valve place is provided with a breathing pipe and is communicated with one-way valve, one-way valve is communicated with the secondary air filter cleaner by the air jet cut-off valve, and the air jet cut-off valve also is communicated with the suction tude of cylinder head; Suction tude also is communicated with activated carbon canister by the fuel evaporation control valve; Carburetor also is parallel to the fuel evaporation control valve by negative pressure control switch and suction tude; Deaerator one end is communicated with the engine exhaust mouth, and the other end is communicated with air-strainer, and air-strainer is communicated with the fuel evaporation control valve: fuel tank is communicated with activated carbon canister, negative pressure control switch respectively, more than each parts adopt pipe to connect.
Owing to adopted such scheme, after air filters by the secondary air filter cleaner, enter air outlet flue through air jet cut-off valve, one-way valve, breathing pipe, impel CO imperfect combustion in the waste gas and nytron compounds to carry out secondary combustion, reduce CO and hydrocarbon compounds content in the discharging waste gas.The gas blowby that engine chamber is discharged from flue gas leading after deaerator is introduced the air-strainer filtration, enters combustion chambers burn again, can reduce the content of oxynitrides.Active carbon in the activated carbon canister can adsorb fuel tank and Carburetor vaporized gas, after being drawn into air-strainer and filtering by negative pressure, enters combustion chambers burn again, and the direct discharging of hydrocarbon when reducing Parking reduces the pollution to atmosphere.
The utility model is described in further detail below in conjunction with drawings and Examples.
(4). description of drawings
Fig. 1 is a structural representation of the present utility model.
(5). embodiment
Referring to Fig. 1, the air-strainer 2 on the motor is communicated with the suction tude 5 of cylinder head by Carburetor 7.Cylinder head 14 exhaust valve places are provided with a through hole, rely on breathing pipe 3 one-way valve 4 outer with being fixed on cylinder head to be communicated with.One-way valve 4 is communicated with secondary air filter cleaner 8 by air jet cut-off valve 6, and air jet cut-off valve 6 also is communicated with the suction tude 5 of cylinder head, and suction tude 5 also is communicated with activated carbon canister 13 by fuel evaporation control valve 11.Carburetor 7 is parallel to fuel evaporation control valve 11 by negative pressure control switch 12 and suction tude 5; Deaerator 9 one ends are communicated with the waste gas mouth of motor 1, and the other end is communicated with air-strainer 2, and air-strainer 2 is communicated with fuel evaporation control valve 11; Fuel tank 10 is communicated with activated carbon canister 13, negative pressure control switch 12 respectively.
Air jet cut-off valve 6 is by negative pressure, and control ambient air inlet passage 3 enters in the air outlet flue of motor 1 again; Fuel evaporation control valve 11 is by negative pressure, and the fuel vapor of control fuel tank 10 enters air-strainer; Negative pressure control switch 12 is by negative pressure, and the fuel vapor in the control Carburetor 7 enters air-strainer 2.
During engine operation, air enters Carburetor 7 after filtering by air-strainer 2, after fuel oil in the Carburetor 7 mixes, enters the firing chamber in the motor 1, again ignition.Simultaneously, air is subjected to the control of air jet cut-off valve 6 after also filtering by secondary air filter cleaner 8, enters cylinder head 14 air outlet flues through one-way valve 4 from breathing pipe 3, impels CO imperfect combustion in the waste gas and hydrocarbon to carry out secondary combustion.After the secondary combustion, CO and hydrocarbon in the discharging waste gas reduce in a large number.In addition, the gas blowby that engine chamber is discharged from flue gas leading after deaerator 9 is introduced air-strainer 2 filtrations, enters firing chamber 1 burning again, can reduce the content of hydrocarbon.
During Parking, motor quits work, fuel tank 10 and Carburetor 7 vaporized gas, by the active carbon adsorption in the activated carbon canister 13 that is communicated with it, after treating engine start, after the fuel-steam of absorption is drawn into air-strainer 2 filtrations by negative pressure in the activated carbon canister 13, enter the firing chamber of motor 1 again, the direct discharging of hydrocarbon when reducing Parking reduces the pollution to atmosphere.
