Abstract
The utility model discloses a kind of cylinder head of general gasoline engines, including air intake duct, inlet valve conduit, exhaust duct and exhaust valve guide, the end face of gas lid is equipped with concave surface, the concave surface that air intake duct, inlet valve conduit, exhaust duct and exhaust valve guide are equipped with gas lid end face interlinks, the guide rod of inlet valve and the guide rod of exhaust valve are installed on respectively in inlet valve conduit and exhaust valve guide, cylinder head end face sets one end with concave surfaces and is arranged on one end of cylinder body, and the inlet valve conduit and exhaust manifolds axis and the equal structure of cylinder body axis are at an angle.The cylinder head of the general gasoline engines can not only improve air inlet and exhaust efficiency, so as to ensure the normal operation of general gasoline engines.
Description
Technical field
The utility model is related to a kind of cylinder head of general gasoline engines.
Background technology
A kind of existing general gasoline engines, containing cylinder crankcase, which includes cylinder block and crankcase.
Cylinder block is located at the one side of crankcase, and cylinder block and crankcase are a whole structure.Cylinder block includes cylinder body and cylinder
Lid.Cylinder head includes air intake duct, inlet valve conduit, exhaust duct and exhaust valve guide, and the end face of gas lid is equipped with concave surface, air inlet
The concave surface that road, inlet valve conduit, exhaust duct and exhaust valve guide are equipped with gas lid end face interlinks.The guide rod of inlet valve
It is installed on respectively in inlet valve conduit and exhaust valve guide with the guide rod of exhaust valve.Cylinder head end face sets one end with concave surfaces and sets
On one end of cylinder body.Inlet valve and exhaust valve in cylinder head control respectively the unlatching of air intake duct and exhaust duct and
It closes.Since the axis of the guide rod of the guide rod and exhaust valve of inlet valve is parallel with cylinder body axis, that is to say, that inlet valve
It is vertical with cylinder body axis with exhaust valve, thus when air-flow enters cylinder body from air intake duct and inlet valve can generate it is certain
Intake resistance, so as to influence engine charging efficiency.Equally, waste gas stream is certain through that can be generated during exhaust duct from cylinder body
Exhaust resistance, so as to influence exhaust efficiency.The above situation affects the normal operation of general gasoline engines.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of cylinder head of general gasoline engines, the general gasoline engines
Cylinder head can not only improve air inlet and exhaust efficiency, so as to ensure the normal operation of general gasoline engines.
In order to solve the above technical problems, a kind of cylinder head of general gasoline engines of the utility model, including air intake duct, inlet valve
Conduit, exhaust duct and exhaust valve guide, the end face of gas lid are equipped with concave surface, air intake duct, inlet valve conduit, exhaust duct and exhaust
The concave surface that is equipped with gas lid end face of door conduit interlinks, the guide rod of inlet valve and the guide rod of exhaust valve be installed on respectively into
In valve guide bushing and exhaust valve guide, cylinder head end face sets one end with concave surfaces and is arranged on one end of cylinder body, it is described into
Valve guide bushing and exhaust manifolds axis and the equal structure of cylinder body axis are at an angle.
The inlet valve conduit and exhaust manifolds axis and the angle that cylinder body axis is formed are 15 degree 20 degree.
In the cylinder head of above-mentioned general gasoline engines, due to inlet valve conduit and exhaust manifolds axis and cylinder body axis
Equal structure is at an angle, thus air-flow from air intake duct and inlet valve enter cylinder body when intake resistance reduce, waste gas stream is from gas
Cylinder body reduces through exhaust resistance during exhaust duct, so as to improve air inlet and exhaust efficiency, has ensured the normal fortune of general gasoline engines
Row.
Description of the drawings
Fig. 1 is a kind of structure diagram of the cylinder head of general gasoline engines of the utility model.
Specific embodiment
In Fig. 1, a kind of cylinder head of general gasoline engines, including air intake duct 8, inlet valve conduit 7, exhaust duct 2 and exhaust valve
Conduit 1, the end face of gas lid are equipped with concave surface 5, and air intake duct 8, inlet valve conduit 7, exhaust duct 2 and exhaust valve guide 1 are and gas
The concave surface 5 that lid end face is equipped with interlinks.The guide rod of inlet valve and the guide rod of exhaust valve are installed on 7 He of inlet valve conduit respectively
In exhaust valve guide 1.Cylinder head end face sets one end with concave surfaces and is arranged on one end of cylinder body.The inlet valve conduit and
Exhaust manifolds axis and the equal structure of cylinder body axis are at an angle, i.e., the axis 6 of inlet valve conduit is formed with cylinder body axis 4
One angle, exhaust manifolds axis 3 and 4 structure of cylinder body axis are at an angle.
To improve air inlet and exhaust efficiency and production cost, 7 axis 6 of inlet valve conduit and 1 axis 3 of exhaust manifolds with
The angle that cylinder body axis 4 is formed is 15 degree 20 degree.
In the cylinder head of above-mentioned general gasoline engines, due to 7 axis 6 of inlet valve conduit and 1 axis 3 of exhaust manifolds and cylinder
4 equal structure of body axis is at an angle, thus air-flow from air intake duct 7 and inlet valve enter cylinder body when intake resistance reduce,
Waste gas stream reduces from cylinder body through exhaust resistance during exhaust duct 2, so as to improve air inlet and exhaust efficiency, has ensured all-purpose gasoline
The normal operation of machine.
