Abstract
The utility model discloses a secondary combustion system of a motorcar engine. The secondary combustion system comprises a secondary gulp valve, a cylinder cover and a cylinder head, wherein the cylinder cover is arranged on the upper surface of the cylinder head; the secondary gulp valve is arranged on the upper surface of the cylinder cover; a secondary air compensating hole on the cylinder head is arranged above an exhaust port of the cylinder head; the lower part of the cylinder head is provided with a secondary air compensating hole duct connected with the secondary air compensating hole on the cylinder head; the upper part of the cylinder cover, that is, the upper part of the secondary air compensating hole duct is provided with a secondary air compensating cabin; and the secondary air compensating cabin is connected with an air compensating port on the secondary gulp valve. Compared with the existing secondary combustion system of the motorcar engine, the secondary combustion system is designed more reasonably and has better durability; therefore, the problem that the secondary gulp valve of the motorcar is easy to damage can be solved.
Description
Technical field
The utility model relates to a kind of component of motorcycle, more specifically to the secondary combustion system that uses on a kind of motorcycle engine.
Background technique
Motorcycle engine also has partially mixed gas not have perfect combustion after lighting the acting of compressed mixed gas, but arrives the atmosphere the inside through emission by exhaust pipe, has so both wasted Fuel Petroleum and has also produced bigger air pollutant.Existing motorcycle engine secondary combustion system is made up of secondary air-supplementing valve, cylinder head, cylinder head, the design of secondary air compensating hole is on the right of cylinder head relief opening, secondary air-supplementing valve is directly installed on the secondary air compensating hole of cylinder head, because the relief opening of secondary air-supplementing valve and motorcycle engine cylinder head is too close, and relief opening temperature height (800 ℃～1000 ℃), pressure are big, are easy to cause caulking gum, the reed ageing failure of secondary air-supplementing valve.
The model utility content
The purpose of this utility model is the shortcoming that overcomes prior art, provides that a kind of design is more reasonable, the better motorcycle engine secondary combustion of durability system, solves the problem that the motorcycle secondary aeration valve damages easily.
The purpose of this utility model is achieved by the following technical programs.
A kind of motorcycle engine secondary combustion of the utility model system, in original motorcycle engine secondary combustion system, convert, the utility model is the same with prior art, form by secondary air-supplementing valve, cylinder head, cylinder head, main change structure is as follows: cylinder head is installed on above the cylinder head, secondary air-supplementing valve is installed on above the cylinder head, and the secondary air compensating hole design on the cylinder head is above the relief opening of cylinder head; The secondary air compensating duct that is connected with secondary air compensating hole on the cylinder head is arranged at the cylinder head bottom, and cylinder head top is that the secondary air compensating storehouse is arranged at top, secondary air compensating duct, and the secondary air compensating storehouse is connected with gas supplementing opening on the secondary air-supplementing valve, and other structures keep original state constant.
Mixed gas behind the engine combustion is by exhaust valve process relief opening, outlet pipe; be discharged into the atmosphere the inside; the beneficial effects of the utility model are in use this secondary combustion system to be fixed on the waste gas that can draw exhaust ports on the motor; through the secondary air compensating hole of cylinder head, the secondary air compensating duct of cylinder head; arrive the tonifying Qi storehouse; add to through secondary air-supplementing valve at last and carry out secondary combustion in the motor; the final function that realizes the mixed gas secondary combustion plays the effect that reduces discharging, protection environment.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model motorcycle engine secondary combustion system;
Among the figure 1, cylinder head; 2, cylinder head; 3, secondary air-supplementing valve; 4, secondary air compensating hole; 5, secondary air compensating duct 6, tonifying Qi storehouse; 7, cylinder head bolt mounting hole; 8, cylinder head bolt mounting hole; 9, bolt hole; 10, secondary air-supplementing valve bolt mounting holes.
Embodiment
A kind of motorcycle engine secondary combustion system, in original motorcycle engine secondary combustion system, convert, as shown in drawings, form by secondary air-supplementing valve, cylinder head, cylinder head, the secondary air compensating hole is designed above the cylinder head relief opening, simultaneously 3 cylinder head bolt mounting holes are set on cylinder head, other structures of cylinder head keep original state constant.The secondary air compensating oral pore road that matches in one of the bottom of cylinder head design and secondary air compensating hole on the cylinder head, the top of cylinder head is secondary air compensating storehouse of upper design and 3 cylinder head bolt mounting holes and 2 bolt holes in secondary air compensating duct, and other structures of cylinder head keep original state constant.The secondary air compensating hole of secondary air compensating oral pore road and cylinder head is connected, uses 3 bolts to pass cylinder head bolt mounting hole and cylinder head bolt mounting hole and connect cylinder head is installed in above the cylinder head; At gas supplementing opening of the bottom of secondary air-supplementing valve design, 2 secondary air-supplementing valve bolt mounting holes of both sides design, the secondary air compensating storehouse of gas supplementing opening and cylinder head is connected, and the bolt hole of using 2 bolts to pass secondary air-supplementing valve bolt mounting holes and cylinder head is fixed on secondary air-supplementing valve on the cylinder head.
Claims (1)
1. motorcycle engine secondary combustion system, form by secondary air-supplementing valve, cylinder head, cylinder head, it is characterized in that cylinder head is installed on above the cylinder head, secondary air-supplementing valve is installed on above the cylinder head, and the secondary air compensating hole on the cylinder head is positioned at the relief opening top of cylinder head; The secondary air compensating duct that is connected with secondary air compensating hole on the cylinder head is arranged at the cylinder head bottom, and cylinder head top is that the secondary air compensating storehouse is arranged at top, secondary air compensating duct, and the secondary air compensating storehouse is connected with gas supplementing opening on the secondary air-supplementing valve.
