Description
Technical field
The utility model relates to a kind of motorcycle engine, especially a kind of single-cylinder air-cooled Four valve motorcycle engine cylinder
Head.
Background technique
Currently, air-cooling motorcycle engine in the market is based on two valves, although can satisfy conventional driving,
It is for pursuing the off-road motorcycle of ultimate attainment performance, it is clear that its performance is just unable to satisfy cross-country requirement；Such as use two valves
Water-cooled engine, the vehicle frame of off-road motorcycle can not but carry.In order to solve this problem, many manufacturers just use Four valve
Air cooling engine, although it is this do it is feasible, due to existing Four valve air cooling engine cylinder head structure limit, cause
Combustion chamber in cylinder head still has the bad problem of performance in terms of to fuel burning, air inlet and exhaust.
Utility model content
The purpose of this utility model is just to provide a kind of single-cylinder air-cooled Four valve that can effectively improve engine combustion performance
Motor car engine cylinder end.
The purpose of this utility model is that technical solution in this way is realized, a kind of single-cylinder air-cooled Four valve motorcycle hair
Motivation cylinder head, including cylinder head ontology are provided with combustion chamber in the cylinder head ontology, are provided with edge on the Inner Wall of Combustion Chamber
Air inlet A and air inlet B, exhaust outlet A and the exhaust outlet B that horizontal line is arranged symmetrically, on the Inner Wall of Combustion Chamber and be located at into
Between port A and exhaust outlet A, water conservancy diversion protrusion A and water conservancy diversion protrusion B are respectively arranged between air inlet B and exhaust outlet B.
In order to guide air flow direction exhaust valve, set on the Inner Wall of Combustion Chamber and between exhaust outlet A and exhaust outlet B
It is equipped with shunting protrusion.
Wherein, the water conservancy diversion protrusion A, water conservancy diversion protrusion B and shunting protrusion are chevron shaped.
It further describes, the big end of the water conservancy diversion protrusion A is connect with Inner Wall of Combustion Chamber, and small end protrudes into air inlet A and exhaust
Between mouth A and small end end is between air inlet A horizontal center line, the small end and air inlet A outer rim and exhaust outlet A outer rim
With gap.
It further describes, the big end of the water conservancy diversion protrusion B is connect with Inner Wall of Combustion Chamber, and small end protrudes into air inlet B and exhaust
Between mouth B and small end end is between air inlet B horizontal center line, the small end and air inlet B outer rim and exhaust outlet B outer rim
With gap.
In the present invention, the big end for shunting protrusion is connect with Inner Wall of Combustion Chamber, and small end protrudes into exhaust outlet A and row
There is gap between port B and with exhaust outlet A outer rim and exhaust outlet B outer rim.
By adopting the above-described technical solution, the utility model has smart structural design, practical reliable, low-cost
Advantage can effectively promote the combustibility and emission performance of cylinder head using it, so that the power of engine gets a promotion.
Detailed description of the invention
The Detailed description of the invention of the utility model is as follows:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing, but the utility model
These embodiments are not limited to, any improvement or substitution on the present embodiment essence spirit still falls within the utility model
Claim range claimed.
Embodiment 1: as shown in Figure 1, a kind of single-cylinder air-cooled Four valve motor car engine cylinder end, including cylinder head ontology 1, In
Combuster 2 is set in the cylinder head ontology 1, is provided with the air inlet being arranged symmetrically along horizontal line on 2 inner wall of combustion chamber
Mouth A3 and air inlet B4, exhaust outlet A5 and exhaust outlet B6 on 2 inner wall of combustion chamber and are located at air inlet A3 and exhaust outlet A5
Between, between air inlet B4 and exhaust outlet B6 be respectively arranged with water conservancy diversion protrusion A7 and water conservancy diversion protrusion B8.
In order to further guide air flow direction exhaust valve, on 2 inner wall of combustion chamber and it is located at exhaust outlet A5 and exhaust
Shunting protrusion 9 is provided between mouth B6.
In the present invention, the water conservancy diversion protrusion A7, water conservancy diversion protrusion B8 and shunting protrusion 9 are chevron shaped.
It further describes, the big end of the water conservancy diversion protrusion A7 is connect with 2 inner wall of combustion chamber, and small end protrudes into air inlet A3 and row
Between port A5 and small end end is outside air inlet A3 horizontal center line, the small end and air inlet A3 outer rim and exhaust outlet A5
There is gap between edge.
It further describes, the big end of the water conservancy diversion protrusion B8 is connect with 2 inner wall of combustion chamber, and small end protrudes into air inlet B4 and row
Between port B6 and small end end is outside air inlet B4 horizontal center line, the small end and air inlet B4 outer rim and exhaust outlet B6
There is gap between edge.
Wherein, the big end for shunting protrusion 9 is connect with 2 inner wall of combustion chamber, and small end protrudes into exhaust outlet A5 and exhaust outlet B6
Between and with exhaust outlet A5 outer rim and exhaust outlet B6 outer rim there is gap.
In the present invention, due to being provided with water conservancy diversion protrusion A7 on 1 upper combustion chamber of cylinder head ontology, 2 inner wall and water conservancy diversion is convex
Play B8, doing so facilitates mixed gas far from Inner Wall of Combustion Chamber wall surface so that mixed gas more concentrates and combustion chamber 2 in
