Abstract
The utility model provides an improved choke valve structure of a two-stroke engine, which has good sealing performance, can efficiently improve the concentration of mixed gas in the engine, and further improves the cold start performance of the engine. The improved choke valve structure includes a choke valve and an air filter housing, and is characterized in that a protruding object is arranged on the choke valve, and a bulge is arranged on the air filter housing.
Description
Technical field
The utility model relates to technical field of engines, is specially a kind of modified model two stroke engine of the choke flap structure.
Background technique
Small-sized two-stroke hand-held engine is being easy to fire burns in order to make in the cylinder when cold start-up, through the method for closing chock plate mixture strength is improved.Traditional two stroke engine choke gear edge is easy to gas leakage, thereby does not reach desirable air fuel ratio concentration, and cold machine state motor is difficult to start.
Summary of the invention
To the problems referred to above, the utility model provides a kind of modified model two stroke engine of the choke flap structure, and its good seal performance can effectively improve engine mixed gas concentration, thereby improves the engine cold-start performance.
Its technological scheme is such: it comprises chock plate and empty filter outer cover, and it is characterized in that: said chock plate is provided with protruding thing, and said empty filter outer cover is provided with convexity.
It is further characterized in that: the protruding thing of said chock plate when said chock plate is closed its position over against chock plate middle part; Said empty filter outer cover raised position is over against the chock plate middle part; When said chock plate is closed, protruding thing of said chock plate and the protruding surface of contact frictional fit of said empty filter outer cover.
Use the utility model structure two stroke engine of the choke flap structure; Its beneficial effect is: it effectively reduces the gap between motor chock plate and the air door, and during engine start, mixture strength is stable; Improved the engine cold-start performance, motor is easy to start.

Fig. 2 is an A portion partial enlarged drawing among Fig. 1;
Fig. 3 is choke closed state hold device figure;
Fig. 4 is chock plate opening state figure.
Embodiment
See Fig. 1, Fig. 2, the utility model comprises chock plate 4 and empty filter outer cover 3, and chock plate 4 is provided with protruding thing 5, and it is protruding 6 that empty filter outer cover 3 is provided with, the protruding thing 5 of chock plate when chock plate 4 is closed its position over against chock plate 4 middle parts; Protruding 6 positions of empty filter outer cover are over against the chock plate middle part; When chock plate 4 is closed; Protruding thing 5 of chock plate and the empty protruding 6 surface of contact frictional fit of outer cover of filtering, the mutual frictional force that produces leaches mouth with chock plate 4 and sky and fits each other along the limit closely, has reduced the gap between air door connection and the chock plate 4; Improve sealability, thereby improved mixture strength.Fresh air gets into after the sky filter, gets into motors through the inlet hole on the chock plate 48, because chock plate inlet hole 8 diameters are less, the amount of fresh air of passing through is few, in Carburetor, produces rich mixture entering starting work subsequently.Among the figure, the 1st, empty filter inner cover, the 2nd, filter core, the 7th, chock plate handle.
