Abstract
The utility model discloses a quadruple cylinder engine cylinder cover exhaust structure which comprises a cylinder cover body. The cylinder cover body comprises a first combustion chamber dome, a second combustion chamber dome, a third combustion chamber dome and a fourth combustion chamber dome which correspond to cylinder holes in a cylinder body and are sequentially arranged, a first exhaust hole, a second exhaust hole and a third exhaust hole are formed in the cylinder cover body, the first combustion chamber dome is communicated with the first exhaust hole through an exhaust channel, the fourth combustion chamber dome is communicated with the third exhaust hole through an exhaust channel, and the second combustion chamber dome and the third combustion chamber dome are simultaneously communicated with the second exhaust hole respectively through exhaust channels. The quadruple cylinder engine cylinder cover exhaust structure can effectively solve the problem of exhaust frustration caused by mutual interference when gas is exhausted, so that the usage rate of fuels is effectively increased, and the fuels are saved.
Description
Technical field
The utility model relates to technical field of automobile parts, relates in particular to a kind of four cylinder engine cylinder head exhaust structure.
Background technique
Engine cylinder cap is one of important spare part in motor car engine, in cylinder head, there is the firing chamber dome corresponding with each cylinder-bore (firing chamber is generally the combination of the cylinder-bore in arc dome and the cylinder block in cylinder head), in cylinder head, be provided with the gas-entered passageway and outlet passageway and inlet hole and the exhaust port that are connected with each firing chamber dome; Exhaust port in current cylinder head is one, and institute's combuster dome is all connected with described exhaust port by exhaust passage.But this structure of such cylinder can cause gas to form phase mutual interference at exhaust port place in the course of the work, thereby causing gas to be discharged is obstructed, affect the normal discharge of gas, the energy part that so just easily causes fuel to produce is discharged gas for overcoming interference, thereby cause the waste of fuel, reduced the utilization rate of fuel.
Model utility content
For prior art above shortcomings, the purpose of this utility model is just to provide a kind of four cylinder engine cylinder head exhaust structure, can effectively solve gas discharge time, discharge the problem of being obstructed because phase mutual interference causes, thereby effectively improve the utilization rate of fuel, and then fuel saving.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of four cylinder engine cylinder head exhaust structure, comprise cylinder head body, described cylinder head body has the first firing chamber dome corresponding with each cylinder-bore in cylinder block and that set gradually, the second firing chamber dome, the 3rd firing chamber dome and the 4th firing chamber dome, it is characterized in that: on cylinder head body, offer first row pore, second row pore and the 3rd exhaust port; Described the first firing chamber dome is connected with first row pore by exhaust passage, the 4th firing chamber dome is connected with the 3rd exhaust port by exhaust passage, and the second firing chamber dome and the 3rd firing chamber dome are connected with second row pore by exhaust duct respectively simultaneously.
Further, two days exhaust ducts between the second firing chamber dome and the 3rd firing chamber dome and second row pore are parallel to each other.
Compared with prior art, the utlity model has following advantage: simple in structure, interference-free each other when each firing chamber dome carries out exhaust by exhaust passage, thus avoid being obstructed because of the discharge that interference causes, can effectively improve like this utilization rate of fuel, and then fuel saving.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
In figure: 1-cylinder head body, 2-first row pore, the 3-the three exhaust port, 4-second row pore.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: referring to Fig. 1, a kind of four cylinder engine cylinder head exhaust structure, comprise cylinder head body 1, described cylinder head body has the first firing chamber dome corresponding with each cylinder-bore in cylinder block and that set gradually, the second firing chamber dome, the 3rd firing chamber dome and the 4th firing chamber dome.On cylinder head body 1, offer first row pore 2, second row pore 4 and the 3rd exhaust port 3; Described the first firing chamber dome is connected with first row pore 2 by exhaust passage, the 4th firing chamber dome is connected with the 3rd exhaust port 3 by exhaust passage, and the second firing chamber dome and the 3rd firing chamber dome are connected with second row pore 4 by exhaust duct respectively simultaneously.
Two days exhaust ducts between the second firing chamber dome and the 3rd firing chamber dome and second row pore 4 are parallel to each other.
Interference-free each other when each firing chamber dome carries out exhaust by exhaust passage, thus avoid being obstructed because of the discharge that interference causes, can effectively improve like this utilization rate of fuel, and then fuel saving.
Finally it should be noted that, above embodiment is only in order to the technical solution of the utility model to be described but not restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or are equal to replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present utility model.
Claims (2)
1. a four cylinder engine cylinder head exhaust structure, comprise cylinder head body, described cylinder head body has the first firing chamber dome corresponding with each cylinder-bore in cylinder block and that set gradually, the second firing chamber dome, the 3rd firing chamber dome and the 4th firing chamber dome, it is characterized in that: on cylinder head body, offer first row pore, second row pore and the 3rd exhaust port; Described the first firing chamber dome is connected with first row pore by exhaust passage, the 4th firing chamber dome is connected with the 3rd exhaust port by exhaust passage, and the second firing chamber dome and the 3rd firing chamber dome are connected with second row pore by exhaust duct respectively simultaneously.
2. four cylinder engine cylinder head exhaust structure according to claim 1, is characterized in that: two days exhaust ducts between the second firing chamber dome and the 3rd firing chamber dome and second row pore are parallel to each other.
