6 be exhaust outlet, and 7 be air inlet, and 8 be water outlet, and 9 be thermostat.In the following with reference to the drawings and specific embodiments to of the invention a kind of
Engine cylinder head is described further.
Specific implementation mode
Technical scheme of the present invention：As shown in attached drawing 2-6, a kind of engine cylinder head includes cylinder head ontology 2, rocking arm branch
Frame 1 and camshaft 3, combuster 4 is opened up on cylinder head ontology 2, and the surface of combustion chamber 4 forms air intake duct and (do not marked in attached drawing
Show), exhaust duct (not indicated in attached drawing) and spark plug mounting hole 5, spark plug is installed (in attached drawing on spark plug mounting hole 5
It does not indicate).
As shown in attached drawing 3-6,2 lower end of cylinder head ontology is provided with air inlet 7, exhaust outlet 6, water outlet 8, and air inlet 7 connects
Tap into air flue, exhaust outlet 6 connects exhaust duct, and air inlet 7 and water outlet 8 are set to 2 homonymy of cylinder head ontology, water outlet 8 it is outer
It encloses and is connected with thermostat 9, exhaust outlet 6 is set to side opposite with air inlet 7 on cylinder head ontology 2.Side where air intake duct
Cylinder head has air cooling effect since the air of entrance is normal temperature air, therefore temperature is relatively low, and passes through cooling cycle
Cooling water temperature out increases, by water outlet 8 be arranged in 7 the same side of air inlet, may insure the equal of cooling effect in this way
It is even consistent.
Water outlet 8 connects water pipe (not indicated in attached drawing) in the prior art, and thermostat is external, and section temperature is connected by water pipe
Device, not only cooling effect is poor, and of high cost.As shown in attached drawing 5,6, thermostat 9 is directly arranged at water outlet 8 by the present invention,
Ensure that engine works within the scope of suitable temperature, the effects that saving energy consumption can be played, production cost has been saved, ensured simultaneously
Cooling effect.
Cylinder head ontology 2 is integrated casting and forming, and air inlet 7 is obliquely installed, therefore has reserved more skies in air inlet side
Between air inlet 7 and water outlet 8 be set to homonymy, while air intake duct can be set to EFI air intake duct.Exhaust outlet 6 is set to convex
The lower section of wheel shaft 3,6 angled bias of exhaust outlet, meets installation requirement.
Automatic pressure reducing valve (not indicated in attached drawing) is installed on camshaft 3, automatic pressure reducing valve is set on camshaft 3, and
It is rotated coaxially with camshaft 3, eliminates drawback caused by installation hand reducing pressure valve.
In a preferred embodiment, air intake duct is EFI air intake duct, improves volumetric efficiency using fluctuation effect, and can be with
The pressure environment in pressure stabilizing cavity is set to stablize relatively, to provide good condition using dynamic effect, while it is mutual to eliminate each cylinder air inlet
Interference improves intake uniformity.
