After supporting element 2 and cylinder head kingbolt 1 are relatively fixed, sealing element 4 is sleeved on to the outside of supporting element 2, is locked by rotation
Nut 3, locking nut 3 make sealing element 4 be resisted against the outer surface of integrated cylinder housing 5, are made by the rotation of locking nut 3
It obtains sealing element 4 and the pressing force for the outer surface for being resisted against integrated cylinder housing 5 increases, to realize supporting element 2 and via hole
The gap formed between 51 is sealed, and interconnecting piece 24 and the installation site of engine intake and exhaust system are attached, thus
Realize effective fixation of engine intake and exhaust system.
Further, the diameter of the interconnecting piece 24 is less than the diameter of the supporting element 2, the periphery wall of the interconnecting piece 24
On offer third external screw thread 241.In above structure between interconnecting piece 24 and supporting element 2 formed shoulder structure, when engine into
Interconnecting piece 24 is passed through the mounting hole on engine intake and exhaust system by exhaust system after being installed, so that engine breathing system
Unite against shoulder structure on, by using nut and third external screw thread 241 cooperation realization engine intake and exhaust system it is quick
Installation.
Further, the radial section of the operation portion 23 is regular polygon.It, can by the above structure of operation portion 23
It is effectively matched the structure of installation tool, consequently facilitating installation operation, improves the efficiency of installation.
It is to be appreciated that above-mentioned just changeable row using regular hexagon as optimum embodiment, can also be other polygon certainly
The structure of shape, then this, the application no longer repeats.
Specifically understand, the sealing element 4 is tubular rubber part, including sealing 42 and damping portion, the damping portion
It is circumferentially positioned at the outside of the sealing 42, the internal diameter of the damping portion is greater than the diameter of the via hole 51；The sealing
42 are sleeved on 2 periphery wall of supporting element, the sealing 42 towards the end face of the integrated cylinder housing 5 be taper
Face, the tapered surface are caught in the gap between the via hole 51 and the supporting element 2；The damping portion and the integrated gas
The outer surface of cylinder head cover 5 leans.Above-mentioned sealing element 4 is tubular rubber part, and sealing 42 is arranged in inside, and vibration damping portion annular is set
It sets in the outside of sealing 42, the setting of vibration damping portion is protruded in 42 two sides of sealing respectively, and two end faces that sealing 42 protrudes are cone
Shape face structure.When sealing element 4 is sealed, the tapered surface of sealing 42 is caught in the gap that supporting element 2 and via hole 51 are formed, and is subtracted
Vibration portion is resisted against the outer surface of integrated cylinder housing 5.With this configuration, the close of integrated cylinder housing 5 is on the one hand realized
Envelope, meanwhile, it is capable to the superposition for effectively avoiding junction from vibrating, so as to which the strength and stability of system is effectively ensured.
Specifically, the end face of the damping portion towards the integrated cylinder housing 5 is embedded with the first copper ring 43, and described
One copper ring 43 is coaxially disposed with the supporting element 2, the end face towards the integrated cylinder housing 5 of first copper ring 43 with
The end face towards the integrated cylinder housing 5 of the damping portion is concordant；The damping portion is far from the integrated cylinder cover
The end face of cover 5 is embedded with the second copper ring 44, and second copper ring 44 is coaxially disposed with the supporting element 2, second copper ring 44
The end face and the damping portion far from the integrated cylinder housing 5 the end face far from the integrated cylinder housing 5 it is flat
Together.The first copper ring 43 and the second copper ring 44 are set by the both ends in vibration damping portion, so that vibration damping portion strong obtains effectively itself
Increase, avoids the service life of sealing element 4 being improved, to drop using the generation of the routed damage phenomenon in the vibration damping portion occurred for a long time
The cost of low maintenance.
Specifically, the edge of the via hole 51 is provided with reinforcing rib, and the reinforcing rib is arranged in the integrated cylinder cover
On the inner side end of cover 5.It is avoided by setting reinforcing rib structure so that the intensity of the edge of via hole 51 is effectively enhanced
Integrated cylinder housing 5 caused by sealing element 4 or other components damages the generation of phenomenon, to effectively reduce integrated cylinder
The maintenance cost of housing 5.
Specifically, the air inlet system and exhaust system include air filter, after-treatment system and silencer, wherein air filter, silencer
Refer to the prior art with the specific structure of after-treatment device, and therefore not to repeat here.
