Problems solved by technology

[0002] At present, the known chamfering of the intake port on the bottom surface of the cylinder head is a regular peripheral chamfering, which is easy to process and has good manufacturing processability; the disadvantage is: in the process of gradually opening the intake valve, the The gap between the valve and the chamfer is uniform, and the airflow entering the cylinder from the periphery of the intake valve is also relatively uniform, and it is difficult to form a consistent gas flow; in the case of multiple intake valves, there will be more Such a uniform intake point around the valve makes it more difficult to form the desired large swirl gas flow state

Embodiment Construction

[0012] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0013] figure 1 , 2 Among them, including cylinder head 1, intake valve 2, guide groove 3, intake port 4, arc chamfer 5, etc.

[0014] Such as figure 1 , 2 As shown, the present invention is an air intake guide structure with an intake port on the bottom surface of the cylinder head, including a cylinder head 1, the bottom surface of the cylinder head 1 is connected to the intake port 4, and the bottom surface of the cylinder head 1 corresponds to the entrance of the intake port 4 The position is provided with a guide groove 3, and the direction of the guide groove 3 is consistent with the direction of the spiral vortex of the air inlet 4.

[0015] The guide groove 3 is crescent-shaped, and the depth of the middle part of the guide groove 3 gradually decreases toward both sides.

[0016] The junction of the intake passage 4 and the cyli...

Abstract

The invention belongs to the technical field of internal combustion engine equipment and relates to an air inlet guide structure for air inlet channels. The air inlet guide structure for the air inlet channels comprises an air cylinder cover. The bottom face of the air cylinder cover is connected with the air inlet channels. Guide grooves are formed at the positions, corresponding to inlets of the air inlet channels, of the bottom face of the air cylinder cover. The direction of the guide grooves and the direction of spiral eddies in the air inlet channels are identical. The air inlet guide structure for the air inlet channels is simple and reasonable in structure, targeted improvement is conducted in order to overcome defects of an existing air cylinder cover, eddies in the air cylinder of an engine are enhanced, and it is guaranteed that fresh air and fuel in the air cylinder are more fully and evenly mixed; and tumbles in the air cylinder are enhanced, so that the flame propagation speed in the air cylinder is increased, the combustion efficiency of the engine is higher, and discharged tail gas is cleaner.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engine equipment, and relates to an air intake guide structure used for an air intake channel on the bottom surface of a cylinder head. Background technique [0002] At present, the known chamfering of the intake port on the bottom surface of the cylinder head is a regular peripheral chamfering, which is easy to process and has good manufacturing processability; the disadvantage is: in the process of gradually opening the intake valve, the The gap between the valve and the chamfer is uniform, and the airflow entering the cylinder from the periphery of the intake valve is also relatively uniform, and it is difficult to form a consistent gas flow; in the case of multiple intake valves, there will be more Such a uniform intake point around the valve makes it more difficult to form the desired large swirl gas flow state.
