Abstract
The utility model discloses an air inlet for engine cylinder head, wherein, an air inlet (1) is arranged on a cylinder head and is characterized in that: the middle part of one side wall of the air inlet (1) is sunken towards the air inlet (1). The utility model can improve air input efficiency and dynamic performance of engine inlet and is simple in structure.
Description
Technical field
The utility model belongs to engine art, particularly a kind of inertia intake duct of engine cylinder head.
Background technique
At present, motorcycle engine cylinder head intake duct mostly is straight barrel-shaped and dolioform greatly.These structure intake ducts design unreasonable in high torque engines, make engine power performance bad.
Summary of the invention
The purpose of this utility model provides a kind of engine cylinder head intake duct.It can improve the intake efficiency and the power performance of engine inlets, and simple in structure.
For reaching above-mentioned purpose, the utility model intake duct is arranged on the cylinder head, it is characterized in that: cave in to air flue in the middle part of intake duct one sidewall.
The utility model improves the air inlet rate of intake duct because the middle part of intake duct is set to dumbbell-like shape, and gas can reach the inertia air inlet in intake duct, make engine power improve 5-10%, moment of torsion improves 8-12%, and oil consumption reduces, and therefore can improve the mechanical property of motor.The utility model also has characteristic of simple structure.
Below in conjunction with accompanying drawing the utility model is described further.
Description of drawings
Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is the rotation diagram of a-a face among Fig. 1;
Fig. 3 is the rotation diagram of b-b face among Fig. 1;
Fig. 4 is the rotation diagram of c-c face among Fig. 1;
Fig. 5 is the rotation diagram of d-d face among Fig. 1;
Fig. 6 is the rotation diagram of e-e face among Fig. 1.
Embodiment
Referring to Fig. 1-Fig. 6.Intake duct 1 is arranged on the inlet and outlet door, it is characterized in that: the middle part of a sidewall of intake duct 1 is to air flue 1 depression.
The a-a surface of revolution of air flue 1 is circular, and from b-b surface of revolution rounding off, to c-c, the d-d surface of revolution is circular for cashew nut shape to the e-e surface of revolution.
This intake duct mates with suction tude, Carburetor, empty filter and the silencing apparatus of motor, makes the air inflow abundance of motor, has improved the overall performance of motor, makes engine power improve 5-10%, and moment of torsion improves 8-12%, and oil consumption reduces.
Claims (3)
1. engine cylinder head intake duct, intake duct (1) is arranged on the cylinder head, it is characterized in that: cave in to air flue (1) in the middle part of intake duct (1) one sidewall.
2. engine cylinder head intake duct according to claim 1 is characterized in that: (a-a) surface of revolution of air flue (1) is for circular.
3. engine cylinder head intake duct according to claim 1 is characterized in that: air flue (1) from (b-b) surface of revolution rounding off, to (c-c), (d-d) surface of revolution for cashew nut shape to (e-e) surface of revolution be the circle.
