Abstract
The utility model relates to a motor bicycle engine cylinder head gas filling structure, wherein at least two gas filling ports capable of being matched with an angle pipe are arranged on a cylinder head and are respectively connected with a one-way vacuum valve through the angle pipe and a high temperature pipe, the one way vacuum valve is connected with an air filter through a rubber hose, fresh air in the air filter can enter a cylinder head air filling hole through the rubber hose, the one way vacuum valve, the high temperature pipe and the angle pipe when a motor bicycle engine is started, the air filling holes are respectively communicated with air discharge pipes, thereby enough air can be used to support combustion and to dilute CO, HC and NOX discharged from the air discharge pipes of the cylinder head, thereby CO and HC can be converted into CO2 and H2O as much as possible under the effect of filled air, the content of NOX can be diluted and lowered, the pollution content of motor bicycle engine combustible mixed gas discharged into air after burning can be prominently lowered, the ecological environment can be protected, and the structure is matched with improvement of other component structures to achieve national III standard requirements.
Description
Technical field
The utility model relates to a kind of motorcycle engine, is specifically related to the improvement of motorcycle engine cylinder head gas supplementary structure.
Background technique
In motorcycle engine, atomizing forms burning mixture through Carburetor for gasoline and air, realize air inlet, compression, acting and exhaust cycle by the confined space of compositions such as the component on the motor such as cylinder block, cylinder head, inlet and exhaust valve, spark plug, piston, piston ring, cylinder head pad, chemical energy is converted into the mechanical energy of piston up-down inflammable mixture.Piston links to each other by wrist pin with crankshaft-link rod, and the moving up and down to be converted into of crankshaft-link rod piston rotatablely moves, and realizes the output after the Conversion of energy.In air inlet, compression, acting and the exhaust cycle process of motor, burning mixture enters the firing chamber from cylinder head suction port, intake valve, be compressed, light the acting of promotion piston then, gas after the burning is discharged in the air by exhaust valve, cylinder head air outlet flue, silencing apparatus, gas after directly will burning is in this way discharged from silencing apparatus, make burning mixture also directly be discharged in the air through burning generation and CO, HC, NOx, bring influence to air quality, worsened our living environment, it is strong healthy to have influence on human health.For this reason, country has formulated the pollutant emission standard of vehicle, and forces to carry out, and the Professional visitors has realized the emission request of Europe II by the mode that increases a gas supplementing opening cooperation making-up air device on cylinder head.Along with the further raising of country to emission standard, original product structure can't reach the requirement of state III, therefore seeks the pollutant emission of a kind of reduction motorcycle engine, and the solution that satisfies state III requirement becomes the task of top priority.
Summary of the invention
The purpose of this utility model provide a kind of rational in infrastructure, tonifying Qi is smooth and easy, effectively reduces motorcycle engine and discharges pollutants, and reaches the cylinder head gas supplementary structure of state III emission standard.
Technological scheme
The purpose of this utility model is achieved in that a kind of motorcycle engine cylinder head gas supplementary structure, comprise intake duct, inlet valve seat ring, exhaust valve seat insert, air outlet flue, bend pipe and unidirectional vacuum valve, its special way is: cylinder head is provided with two gas supplementing openings that communicate with air outlet flue, bend pipe is directly installed on respectively on the gas supplementing opening of cylinder head, be provided with heat-insulating block between cylinder head and the bend pipe, unidirectional vacuum valve links to each other by the high temperature pipe with bend pipe.
Described motorcycle engine cylinder head gas supplementary structure, its special way is: two tonifying Qi holes on the cylinder head lay respectively at the upside and the downside of air outlet flue.
Described motorcycle engine cylinder head gas supplementary structure, its special way is: cylinder head is double state cylinder head, and tonifying Qi hole one end that is positioned at the air outlet flue upside communicates with gas supplementing opening, and the other end communicates with two relief openings of air outlet flue respectively.
Described motorcycle engine cylinder head gas supplementary structure, its special way is: tonifying Qi hole one end that is positioned at cylinder head air outlet flue downside communicates with gas supplementing opening, and the other end communicates at exhaust seat ring, air outlet flue connecting part and air outlet flue.
Beneficial effect:
Technological scheme described in the utility model, at least two gas supplementing openings that energy cooperates with bend pipe are set on cylinder head, link to each other with unidirectional vacuum valve respectively with the high temperature pipe by bend pipe, unidirectional vacuum valve links to each other with empty filter by sebific duct, the fresh air that starts in the space-time filter in motorcycle engine passes through sebific duct, unidirectional vacuum valve, high temperature pipe and bend pipe enter cylinder head tonifying Qi hole, the tonifying Qi hole communicates with air outlet flue respectively, so just there are enough air to come CO combustion-supporting and that dilution cylinder head air outlet flue ejects, HC, NOX, make CO, this two classes gas of HC is covering under the air effect of coming, and maximum possible is converted into CO
2And H
2O, the content of NOX obtain dilution and reduce, and the motorcycle engine burning mixture is obviously reduced through being discharged to airborne pollutant load after burning, and have protected ecotope, and the improvement of cooperation remaining part structure has reached the requirement of state III standard.
