Abstract
A kind of cylinder cover of automobile engine air intake duct, it is characterized by comprising cylinder head body, air intake duct, exhaust duct and tappet bore are formed with cylinder head body, between air intake duct and exhaust duct at the top of combuster, air inlet aditus laryngis is formed with the exit of air intake duct, the outlet of air inlet aditus laryngis is formed with annular groove, seat ring is set in annular groove, it is located in the inner wall of air inlet aditus laryngis at the lower end of tappet bore and is formed with concave arc transition face and convex arc-shaped transitional surface, through concave arc transition face and convex arc-shaped transitional surface rounding off between air intake duct, air inlet aditus laryngis and tappet bore.The lower end position secondary operation concave arc transition face of tappet bore and convex arc-shaped transitional surface are located at by the air inlet aditus laryngis inner wall to air intake duct, the position air inlet aditus laryngis is set to obtain rounding off, air inlet is avoided to produce vortex, air from the position by when it is more unobstructed, improve air inflow, make the combustion efficiency of combustion chamber more preferable, so as to improve the power of fuel utilization ratio and engine.
Description
Technical field
The present invention relates to cylinder cover of automobile engine, more particularly to a kind of air intake duct of cylinder cover of automobile engine.
Background technology
Engine cylinder cap is for closed cylinder and forms combustion chamber.Air inlet can be all formed with engine cylinder cap 1 '
Road 2 ' and exhaust duct 3 ', air intake duct and exhaust duct are communicated with combustion chamber, and aditus laryngis 4 ' is formed with the outlet of air intake duct, existing engine
For the aditus laryngis inner wall of cylinder head after machine-shaping, the lower end junction of aditus laryngis and tappet bore can form the step 5 ' of one, and
Handled without secondary operation, when air passes into the stepped locations of the aditus laryngis from air intake duct, there is partial air to be subject to platform
The stop of rank forms vortex, causes air inflow to reduce, so as to influence the combustion efficiency of combustion chamber, ultimately results in the power of engine
Reduce.
The content of the invention
The purpose of the invention is to overcome prior art there are the shortcomings that, there is provided a kind of throat location to air intake duct into
After row secondary operation, aditus laryngis inner wall rounding off, air inlet is more in general, improve a kind of automobile engine cylinder of engine power
Lid air intake duct.
A kind of technical solution of cylinder cover of automobile engine air intake duct of the present invention is：It is characterized by comprising cylinder head sheet
Body, is formed with air intake duct, exhaust duct and tappet bore in cylinder head body, between air intake duct and exhaust duct at the top of combuster, into
The exit of air flue is formed with air inlet aditus laryngis, and the outlet of air inlet aditus laryngis is formed with annular groove, seat ring is set in annular groove, in air inlet aditus laryngis
Wall, which is located at the lower end of tappet bore, is formed with concave arc transition face and convex arc-shaped transitional surface, air intake duct, air inlet aditus laryngis and tappet bore it
Between through concave arc transition face and convex arc-shaped transitional surface rounding off.
The invention discloses a kind of cylinder cover of automobile engine air intake duct, is located at by the air inlet aditus laryngis inner wall to air intake duct
The lower end position secondary operation concave arc transition face of tappet bore and convex arc-shaped transitional surface, make the position air inlet aditus laryngis obtain round and smooth mistake
Cross, avoid air inlet from producing vortex, air from the position by when it is more unobstructed, improve air inflow, make the combustion efficiency of combustion chamber
More preferably, so as to improve the power of fuel utilization ratio and engine.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of cylinder cover of automobile engine air intake duct of the present invention；
Fig. 2 is close-up schematic view at the A of Fig. 1；
Fig. 3 is the structure diagram of existing cylinder cover of automobile engine air intake duct.
Embodiment
The present invention relates to a kind of cylinder cover of automobile engine air intake duct, as shown in Fig. 1-Fig. 2, it is characterised in that：Including gas
Cylinder cap body 1, is formed with air intake duct 2, exhaust duct 3 and tappet bore 4, combuster between air intake duct and exhaust duct in cylinder head body
Top 5, air inlet aditus laryngis 6 is formed with the exit of air intake duct, and the outlet of air inlet aditus laryngis is formed with annular groove, seat ring 8 is set in annular groove,
The inner wall of air inlet aditus laryngis, which is located at the lower end of tappet bore 4, is formed with concave arc transition face 9 and convex arc-shaped transitional surface 10, air intake duct, into
Through concave arc transition face and convex arc-shaped transitional surface rounding off between gas aditus laryngis and tappet bore.Pass through the air inlet larynx to air intake duct 2
Mouthful 6 inner walls are located at the lower end position secondary operation concave arc transition face 9 and convex arc-shaped transitional surface 10 of tappet bore 4, make the position into
Gas aditus laryngis 6 obtains rounding off, avoid air inlet produce vortex, air from the position by when it is more unobstructed, improve air inflow, make
The combustion efficiency of combustion chamber is more preferable, so as to improve the power of fuel utilization ratio and engine.
