Abstract
The utility model discloses a small-displacement high-power motorcycle engine which comprises a cylinder, a cylinder cover and a piston arranged in the cylinder, wherein the cylinder cover is provided with an inlet valve, an exhaust valve and a sparking plug; the upper end surface of the piston is provided with an inlet valve anti-collision groove corresponding to the inlet valve, an exhaust valve anti-collision groove corresponding to the exhaust valve, and a sparking plug anti-collision groove corresponding to the sparking plug; a frustum is arranged at the center of the upper end of the piston; the bottom surface of the cylinder cover at the sides of the inlet valve, the exhaust valve and the sparking plug are all flat surfaces; and the flat surface at the side of the inlet valve, the flat surface at the side of the exhaust valve and the flat surface at the side of the sparking plug are in transition connection by arc surfaces. The bottom surfaces of the cylinder cover at the sides of the inlet valve, the exhaust valve and the sparking plug are flat surfaces, therefore, a plurality of inlet valves and exhaust valves can be arranged, thus greatly improving the air inlet efficiency and the exhaust efficiency; and the frustum is arranged at the center of the upper end surface of the piston and taken as a venting surface, thus improving the venting efficiency in combustion and improving the combustion speed, and further greatly increasing the compression ratio and reducing the fuel consumption rate and the discharge.
Description
(1) technical field
The utility model relates to a kind of
(2) background technique
At present, traditional small displacement engine firing chamber partly is mach spherical combustion chamber in cylinder head, and the squish face cannot be arranged in this firing chamber, and its shape is difficult to arrange plural valve simultaneously; The firing chamber is a spherical shape of protruding at piston portion.Though this types of combustion chamber is simple in structure, the motor of this kind firing chamber exists shortcomings such as compression ratio is low, velocity of combustion slow, discharging is poor, fuel consumption rate height.
(3) summary of the invention
In order to overcome the deficiency that existing small displacement engine compression ratio is low, velocity of combustion slow, discharging is poor, fuel consumption rate is high, the utility model provides a kind of compression ratio that can improve motor greatly, quickening velocity of combustion, reduces the noxious gas emission of motor and increase the high-power motorcycle engine of the thermal efficiency reduction little discharge capacity of fuel consumption rate simultaneously.
The technical scheme in the invention for solving the technical problem is: the high-power motorcycle engine of a kind of little discharge capacity, comprise cylinder, cylinder head, connecting rod, bent axle, be positioned at the piston of described cylinder, the end of described connecting rod is connected with described piston, and the big end of described connecting rod is connected with the connecting rod neck of described bent axle; Described cylinder head is provided with intake valve, exhaust valve and spark plug, and the upper-end surface of described piston is provided with the intake valve corresponding with described intake valve and dodges the hole, dodges the hole and dodge the hole with the corresponding spark plug of described spark plug with the corresponding exhaust valve of described exhaust valve; The central authorities of the upper-end surface of described piston are provided with frustum; On the bottom surface of described cylinder head: the side of described intake valve, exhaust valve, spark plug is the plane, connects with the arc surface transition between the plane of the plane of described intake valve side, described exhaust valve side, the plane of described spark plug side.
The beneficial effects of the utility model are: the bottom surface of the cylinder head of intake valve, exhaust valve, spark plug side is the plane, therefore can arrange a plurality of intake valves and exhaust valve, improves intake efficiency and exhaust efficiency greatly; The central authorities of the upper-end surface of described piston are provided with frustum as the squish face, and the squish effect when increasing burning improves velocity of combustion, thereby can improve compression ratio greatly, reduce fuel consumption rate and discharging.

Fig. 1 is the structural representation of piston upper-end surface.
Fig. 2 is the structural representation of cylinder head bottom surface.
Fig. 3 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, Fig. 3, the high-power motorcycle engine of a kind of little discharge capacity, comprise cylinder 1, cylinder head 2, connecting rod, bent axle, be positioned at the piston 3 of described cylinder 1, the end of described connecting rod is connected with described piston 3, and the big end of described connecting rod is connected with the connecting rod neck of described bent axle;
Described cylinder head 2 is provided with intake valve 4, exhaust valve 5 and spark plug 6, and the upper-end surface of described piston 3 is provided with the intake valve corresponding with described intake valve and dodges hole 7, dodges hole 8 with the corresponding exhaust valve of described exhaust valve and dodge with the corresponding spark plug of described spark plug and cheat 9;
The central authorities of the upper-end surface of described piston 3 are provided with frustum 10;
On the bottom surface of described cylinder head: the side of described intake valve 4, exhaust valve 5, spark plug 6 is the plane, connects with the arc surface transition between the plane of the plane of described intake valve side, described exhaust valve side, the plane of described spark plug side.
The bottom surface of the cylinder head of intake valve 4, exhaust valve 5, spark plug 6 sides is the plane, therefore can arrange a plurality of intake valves and exhaust valve, improves intake efficiency and exhaust efficiency greatly; The central authorities of the upper-end surface of described piston 3 are provided with frustum 10 as the squish face, and the squish effect when increasing burning improves velocity of combustion, thereby can improve compression ratio greatly, reduce fuel consumption rate and discharging.
