Abstract
The utility model discloses a horizontal single cylinder diesel engine having helical intake with round main intake which can reduce the contact areas of the airs and the air wall in an intake and can improve the workability of the diesel engine. A cylinder cover is provided with the intake which supplies the airs to the cylinder. The horizontal single cylinder diesel engine having helical intake with round main intake is characterized in that the main intake is composed of a main intake whose cross section is circular and a helical spiral which conducts rounding-transition connection with the main intake, and the helical spiral is in 3D helical form; the lower end of the spiral part is communicated with the inlet port of the cylinder.
Description
Technical field
The utility model relates to a kind of horizontal single cylinder diesel, and specifically a kind of main air intake is the horizontal single cylinder diesel of round spiral inlet duct.
Background technique
Horizontal single cylinder diesel has advantage simple in structure, easily manufactured, easy to maintenance, that operating cost is low and receives praises from customers.
The quality of air inlet quality directly has influence on the service behaviour of diesel engine in horizontal single cylinder diesel.The sectional shape of the intake duct of traditional horizontal single cylinder diesel has rectangular and square, after air enters the intake duct of above-mentioned sectional shape, bigger with the area of contact of gas wall on the one hand, strengthened intake resistance, flow velocity at the edge of these sectional shapes slows down on the other hand, even can produce disturbance, these shortcomings all can cause the air inlet quality of diesel engine to descend, and the service behaviour of diesel engine is affected.
Summary of the invention
The purpose of this utility model provides and a kind ofly can reduce air and gas wall area of contact in the intake duct, and the band main air intake that improves diesel engine work performance is the horizontal single cylinder diesel of round spiral inlet duct.
Technical solution of the present utility model is:
A kind of is the horizontal single cylinder diesel of round spiral inlet duct with main air intake, it is characterized in that described main air intake by cross section to be round main airway link to each other with rounding off with it, be the spiral helicine spiral part of three dimensional space and form, the lower end of helical part communicates with cylinder intake valve.
The beneficial effects of the utility model:
1, do not changing under the integrally-built situation of horizontal single cylinder diesel, reduced the area of contact of air and gas wall in the horizontal single cylinder diesel main air intake, make the air that enters in the cylinder smooth more, improve the air inlet quality, help improving the service behaviour of diesel engine.
2, intake duct manufacturing of the present utility model is simple, and its moulding process is identical with tratitional technology, and production process, manufacture cost are the same with tratitional technology.
3, applied range not only can be used for the horizontal single cylinder diesel of 1125,1130 types, also can be used for the horizontal single cylinder diesel of other model.
Description of drawings
Fig. 1 is the structural representation of intake duct of the present utility model.
Fig. 2 is that the P of Fig. 1 is to view.
Fig. 3 is the A-A sectional drawing of Fig. 1.
Fig. 4 is the B-B sectional drawing of Fig. 1.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.A kind of is the horizontal single cylinder diesel of 1125 or 1130 types of round spiral inlet duct with main air intake, intake duct at the promising cylinder air feed of cylinder head direct casting, main air intake by cross section to be round main airway 1 link to each other with rounding off with it, be the spiral helicine spiral part 2 of three dimensional space and form, the lower end 3 of spiral part 2 communicates with cylinder intake valve.The entry end 4 of main airway 1 communicates with air intake branch.Main airway 1 and rounding off structure that link to each other, that be the spiral helicine spiral part 2 of three dimensional space with it as shown in Figure 1, its P to view and relevant sectional view respectively shown in Fig. 2,3,4,5.
It is same as the prior art that present embodiment does not relate to part.
