Abstract
The utility model relates to a cylinder cover for a mini car engine for repairing the cylinder abrasion of the engine to obtain the performance index of an original engine. The cylinder cover uses material which is the same as a cylinder; generally, cast steel or cast iron is used. Casts do not allow to have the defects of cracks, through holes, lean, slag enclosure, shrinkage, shrinkage porosity, etc. The cylinder cover is arranged in the cylinder, and then must do a pressure test without a leaking phenomenon. The utility model has the advantages of simple method and low cost; the cylinder cover for a mini car engine can obtain the power performance and the economy of the original engine.
Description
The utility model is the cylinder liner of using in reparation behind the minicar engine cylinder wear.
Cylinder is the important component part of motor car engine.In production practices, in order to improve the quality and to reduce the cost, usually cylinder and piston are carried out classification, when assembling, match.When engine operation, piston is constantly motion in cylinder, so no matter cylinder uses what high-abrasive material, design, manufacturing how conscientiously to improve the quality, cylinder still can wear and tear.The wearing and tearing of cylinder mainly be the ovality of cylinder bore and not the post degree surpass the scope of regulation.When cylinder wear arrived to a certain degree, the power character of motor will significantly descend, and the consumption of fuel and lubricant oil also can sharply increase, particularly minicar engine.At this moment motor just must carry out large repairs, the just essential cylinder of changing during overhaul.The air cylinder structure complexity requires the technical specifications height, the cost height.
The purpose of this utility model is that cylinder liner of design is guaranteeing that the cylinder after the reparation can recover original power character of motor and Economy, and reparation is simple, with low cost again.
The purpose of this utility model is realized by following structure.
Cylinder after the wearing and tearing is repaired, and the cylinder aperture after the reparation is big, can't match with former piston.Process a cylinder liner and pack in the cylinder bore, the endoporus of cylinder liner and former piston match, and the external diameter and the cylinder-bore of cylinder liner match, and general outer diameter D is in 62～70 millimeters scopes.The material of cylinder liner is cast iron or cast steel, through pneumatic test, does not have the seepage phenomenon.
Because adopted the method with edge cover after the cylinder reparation of wearing and tearing, method is simple, and is with low cost, can reach the power character and the Economy of former motor, effective.
Fig. 1 is the structural representation of minicar engine dress cylinder liner.
Concrete structure of the present utility model is provided by following description of drawings and embodiment.
Motor car engine is a multi cylinder, and two cylinders, three cylinders, four cylinders, six cylinders, eight cylinders, twelve-cylinder are even arranged.Commonly used is four cylinders, six cylinders and eight cylinders.The cylinder 1 that has worn and torn is carried out reconditioning, process the external diameter of cylinder liner 2 according to the endoporus of the cylinder after the reconditioning 1, outer diameter D is in 62～70 millimeters scopes.Cylinder 1 is selected interference fit for use with cooperating of cylinder liner 2, and the size of magnitude of interference is selected on demand.The endoporus of cylinder liner 2 matches by the piston diameter of original use.The material selection of cylinder liner 2 and cylinder 1 identical materials, usually usefulness is cast steel, cast iron, foundry goods does not allow defectives such as crackle, open-work, misrun, slag inclusion, shrinkage cavity, shrinkage porosite, and cylinder liner 2 is packed into and must be carried out bulge test behind the cylinder 1, does not have the seepage phenomenon after suppressing.
Claims (2)
1, a kind of minicar engine cylinder liner is characterized in that: cylinder liner (2) is equipped with in cylinder (1) lining after wearing and tearing are repaired, and the endoporus and the former piston of cylinder liner (2) match, and outer diameter D is in 62～70 millimeters scopes.
2, minicar engine cylinder liner according to claim 1 is characterized in that: the material of cylinder liner (2) is cast iron or cast steel, does not have the seepage phenomenon through suppressing test.
