Abstract
The utility model relates to a kind of engine device, is specifically related to a kind of internal combustion engine cylinder device.It comprises cylinder block, the piston be placed in cylinder block, the bent axle that is connected with piston by connecting rod, and cylinder block top is provided with intake valve and exhaust valve, and the diameter of exhaust valve is identical with the diameter of intake valve.This internal combustion engine cylinder device, the diameter of exhaust valve increases identical as the diameter of intake valve, indirectly increase the diameter of cylinder, shorten the working stroke of piston, simultaneously, because of the increase of exhaust valve diameter, cylinder interior gas smooth in exhaust, reduces the pressure of piston stroking upward, less power consumption, thus when discharge capacity remains unchanged, increase the power of motor.In addition, the diameter of intake valve and the equal size of exhaust valve, effectively reduces exhaust noise, is beneficial to sound environmental protection.
Description
Technical field
The utility model relates to a kind of engine device, is specifically related to a kind of internal combustion engine cylinder device.
Background technique
At present, existing explosive motor comprises intake valve and exhaust valve, the diameter of intake valve is obviously greater than the diameter of exhaust valve, improvement intake valve being carried out to supercharging is there is in practical application, with the power of auxiliary increase motor, but this pressurized measure reckons without the pressure of engine cylinder-body exhaust, indirectly adds the pressure of piston stroking upward, thus reduces the power of motor.
Model utility content
The purpose of this utility model is that the exhaust resistance solving the existence of above-mentioned prior art is large, and piston stroking upward is subject to the deficiency of larger pressure, provides one to be beneficial to cylinder block exhaust, increases the internal combustion engine cylinder device of engine power.
The utility model is achieved through the following technical solutions:
A kind of internal combustion engine cylinder device, comprise cylinder block 1, the piston 2 be placed in cylinder block 1, the bent axle 4 that is connected with piston by connecting rod 3, cylinder block 1 top is provided with intake valve 5 and exhaust valve 6, and special way is that the diameter of exhaust valve 6 is identical with the diameter of intake valve 5.
This internal combustion engine cylinder device, the diameter of exhaust valve increases identical as the diameter of intake valve, indirectly increase the diameter of cylinder, shorten the working stroke of piston, simultaneously, because of the increase of exhaust valve diameter, cylinder interior gas smooth in exhaust, reduces the pressure of piston stroking upward, less power consumption, thus when discharge capacity remains unchanged, increase the power of motor.In addition, the diameter of intake valve and the equal size of exhaust valve, effectively reduces exhaust noise, is beneficial to sound environmental protection.
Accompanying drawing explanation
Fig. 1: the structural representation of internal combustion engine cylinder device;
In figure: 1: cylinder block; 2: piston; 3: connecting rod; 4: bent axle; 5: intake valve; 6: exhaust valve.
Embodiment
Referring to accompanying drawing, provide embodiment of the present utility model, be used for being further described structure of the present utility model.
Embodiment 1
The internal combustion engine cylinder device of the present embodiment, comprises cylinder block 1, the piston 2 be placed in cylinder block 1, the bent axle 4 that is connected with piston by connecting rod 3, and cylinder block 1 top is provided with intake valve 5 and exhaust valve 6, and the diameter of exhaust valve 6 is identical with the diameter of intake valve 5.
Compared to the internal combustion engine cylinder device of prior art, when discharge capacity is constant, the diameter of exhaust valve obviously increases, and it is identical with the diameter of intake valve, the exhaust valve that diameter obviously increases makes the gas exhaust in cylinder more smooth and easy, reduce the pressure of piston stroking upward, reduce kinetic equation loss, increase the power of motor.
In addition, the diameter of intake valve and the equal size of exhaust valve, effectively reduces exhaust noise, is beneficial to sound environmental protection.
Above embodiment is not exhaustive, and its protection domain is not limited to given embodiment.Every all technological schemes achieved by thinking of the present utility model, all belong to protection domain of the present utility model.
