Abstract
The utility model provides an improved two-stroke engine exhaust silencer. The exhaust silencer can be used for eliminating a local overheating phenomenon of an engine, and avoiding the cylinder body breakage caused by the local superheating of the engine, and the plastic wire mesh cover molting phenomenon caused by the overhigh environmental temperature of the silencer. The technical scheme of the utility model is as follows: the improved two-stroke engine exhaust silencer comprises a silencer front cover, a silencer rear cover and an accelerant, wherein the silencer front cover is provided with a silencer inlet, the silencer rear cover is provided with a silencer outlet, and the accelerant is arranged in an accelerant cover. The exhaust silencer is characterized in that the joint of the silencer front cover and the silencer rear cover is provided with a silencer baffle plate, the front end of the silencer baffle plate and the accelerant cover are connected and fixed, and a guide plate is fixed on the rear end of the silencer baffle plate.
Description
Technical field
The utility model relates to the motor silencer technical field, the two stroke engine muffler of concrete a kind of improvement.
Background technique
After the engine internal fuel burning; Through baffler waste gas is discharged; Along with various countries' Abgasgesetz increasingly stringent, traditional two stroke engine can not satisfy various countries' exhaust emission standard, so two stroke engine constantly improves discharging through adding catalyst in recent years.At present, general two stroke engine directly is being pressed on catalyst baffler inlet, and directly links to each other with the cylinder body relief opening; The method makes cylinder body relief opening temperature too high; And baffler bonnet temperature is too high, and the serious cylinder body relief opening that causes ruptures, and phenomenons such as guard are burnt in the heat transfer of baffler bonnet.
Summary of the invention
To the problems referred to above; The utility model provides a kind of two stroke engine muffler of improvement; It can eliminate the too high phenomenon of motor local temperature, the cylinder body fracture of avoiding the motor local superheating to cause, and the too high plastics guard melting phenomenon that causes of baffler environment temperature.
Its technological scheme is such: it comprises baffler protecgulum, baffler bonnet and catalyst; Said baffler protecgulum has the baffler import; Have silencing end on the said baffler bonnet, said catalyst is loaded in the catalyst housing, it is characterized in that: said baffler protecgulum and baffler bonnet junction point are provided with the baffler dividing plate; Said baffler dividing plate front end is connected fixing with said catalyst housing, said baffler dividing plate rear end is fixed with guide plate.
It is further characterized in that: have mesopore on the said baffler dividing plate; Said pore location is over against said catalyst position; Said catalyst housing front end has inlet hole; The import of said inlet hole position on the said baffler protecgulum; Said baffler protecgulum inlet is provided with pad; Said guide plate rear end is provided with the double-screw bolt stay tube.
Use the two stroke engine baffler of the utility model structure; Its beneficial effect is: its heat that catalyst secondary combustion is produced cools off inner expansion of baffler; Avoid the engine block temperature local superheating to cause the cylinder body phenomenon of rupture, and the too high plastics guard melting phenomenon that causes of baffler environment temperature.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
See Fig. 1, the utility model comprises baffler protecgulum 2, baffler bonnet 6 and catalyst 9, and baffler protecgulum 2 has baffler import 12; Have silencing end 11 on the baffler bonnet 11; Catalyst 9 is loaded in the catalyst housing 3, and baffler protecgulum 2 is provided with baffler dividing plate 4 with baffler bonnet 6 junction points, and baffler dividing plate 4 front ends are connected fixing with catalyst housing 3; Baffler dividing plate 4 rear ends are fixed with guide plate 5, have mesopore 8 on the baffler dividing plate 4; Mesopore 8 positions are over against catalyst 9 positions; Catalyst housing 3 front ends have inlet hole 10; Inlet hole 10 positions are over against baffler import 12; Baffler protecgulum import 12 places are provided with pad 1; Guide plate 5 rear ends are provided with double-screw bolt stay tube 7.
The gas that produces behind the engine combustion gets into baffler through baffler import 12; Inlet hole 10 by catalyst housing 3 front ends carries out secondary combustion through catalyst 9 again; The gas that produces after the secondary combustion rushes at guide plate 5 through the mesopore on the baffler dividing plate 48; Under the leading role of guide plate 5, discharge by silencing end 11.
Claims (7)
