Description
Application claims is the preference of the french application of 1254594 in the sequence number that on May 21st, 2012 submits, and the disclosure (text, accompanying drawing and claim) of this application is incorporated herein by reference in their entirety.
Technical field
The present invention relates to field of internal combustion engine, wherein cylinder assembly is equipped with the sheath of interpolation.More properly, the present invention relates to the cylinder sheath of the cylindrical wall for housing cylinder of internal-combustion engine, and relate to and comprise the cylinder assembly of the internal-combustion engine that at least one housing has the cylinder of this sheath.
Background technique
In the general form, internal-combustion engine or thermo-motor comprise engine pack, and in described engine pack, inside is formed with at least one cylinder, described cylinder are provided with movably the piston connected with bent axle by the connecting element as connecting rod.Engine pack generally includes three major components, and one of them is called cylinder assembly, and this is because described part comprises one or more cylinder.Hereinafter, unique literary style of " cylinder " assembly is adopted not get rid of the invention of the motor originally comprising single cylinder.
The side of cylinder assembly is coated with cylinder head (the second major component), is furnished with the required parts of internal combustion engine operation in described cylinder head, especially air inlet system, venting gas appliance and optionally ignition mechanism.At opposite side, cylinder assembly is coated with the motor body (the 3rd major component) holding bent axle.
The present invention relates to cylinder assembly, more properly relate to the top being called as cylindrical shell or cylinder.Each cylinder of cylinder shell should be able to send pressure from air and fuel combustion to piston, and guides piston/section assembly translation.Therefore relate to the most responsive and most important region of cylinder shell, this is because powerful thermal and mechanical stress is born on described top: the pressure in cylinder, heat flux, cylinder head on cylinder assembly mechanical fasteners power.
And the distortion of drum surface and form directly affect benefit and the performance of motor, more specifically, engine consumption, the gas flow (i.e. " seepage " gas) of housing and mechanical friction loss is affected.
The material that general use is extremely firm, such as cast iron realize the cylindrical shell that can bear large stress, and the remaining part of cylinder shell can by comparatively light material, typically be aluminum alloy and form.
Therefore cylindrical shell or:
● (when such as casting cylinder shell made of iron) is formed with integral of cylinder shell entirety; Or
● be disconnectable, the sheath therefore added is disconnectable, is namely dismountable relative to the remaining part of housing parts; Or
● (when the aluminum cylinder shell such as with casting sheath made of iron) " around " be inserted in the casting process of the cylinder shell of described cylindrical shell: therefore described sheath is inserted in foundry goods.
The present invention relates to the sheath inserting foundry goods, and relate to the cylinder assembly so obtained.The sheath inserting foundry goods bears multiple stress:
● manufacture stress
● the mechanical stress of fastening cylinder head
● the pressure when the engine is running in cylinder and the heat flux from air/fuel mixed combustion;
● the frictional force of piston/section assembly.
Under these effect of stress, use the type of material and jacket structure to be primary factor, for ensureing the good mechanical strength of sheath, especially ensure that sheath does not ftracture.
In addition, the sheath serving as cylindrical shell should keep cylindrical when the engine is running as much as possible, for ensureing that the good efficiencies of section is avoided too much oil consumption or passed into too many gas to fuel tank.One of them is the most important factor realizing this target is the good adhesive property ensured between assembly and sheath.This adhesiveness mechanically can control the distortion of sheath, ensures the good heat conductivity between sheath and cylinder shell too, and this can make the energy of spontaneous combustion to be discharged well and not change the to-and-fro motion of piston.
In addition, the interface between cylinder assembly and cylinder head, especially the sealing of cylinder head gasket can be damaged at cylinder location place to the unfavorable control of distortion.
In order to respond these problems, from file FR2887926, the known sheath for cylinder assembly comprises the top of taper and be all coated with striped except described top.
The geometrical shape of the sheath provided in this document has multiple advantage.Striped can ensure the good adhesive property between cylindrical shell and gas cylinder hut.Tapered portion can increase the contact surface between sheath and cylinder head gasket, and reduces the spacing between sheath.By reducing this spacing of the special fracture area forming cylinder assembly, also reduce the distortion of part upper cylinder aloft when the engine is running.In fact, assembly applies strong pressure between two adjacent jacket, for the required spacing that " generation " expands.The distortion of the cylinder sheath caused is very unfavorable to the contact between jacket inner wall and the piston of correspondence.The conical by its shape on sheath top or the shape of more generally enlarging also reduce the spacing between two adjacent jacket in size and geometry, improve the performance of entirety during intensification: have the cylinder shell being generally aluminum of larger expansion to promote sheath in the position of tapered portion than being generally casting sheath made of iron, so that make cylindrical shell inside (to main shaft) again close up, and the eminence part that is fastened on of cylinder head trends towards outwards opening.
Because sheath top without stripes can make sheath cylinder assembly in this region slides, limit the different impact of expansion and the risk of cracking.
But, the method relate to cylindrical shell cylindricity when the engine is running well maintained on also need to optimize.
