Abstract
The utility model relates to a piston for a combustion engine, which is used for the fields of locomotives, automobiles, tractors, motorcycles, etc. and is particular suitable for miniature high-speed two-stroke engines. The piston is characterized in that the structure of an original piston is changed, and the defects of the structure of a traditional piston is solved thereby; thus, the sealing performance of an engine can be greatly improved, and the power performance can last forever. The service life of the engine can be extended by more than 1.5 to 2 times. With adoption of the novel structure, the processing step is decreased, and raw materials are saved; for large and medium-sized combustion engines, 3.5 yuan raw materials can be saved for each engine; if the annual output of engines is 150 thousand, 540 thousand yuan can be saved per year.
Description
The utility model relates to all size internal combustion engine, is used for fields such as internal combustion locomotive, automobile, tractor, motorcycle, especially is fit to the miniature high-speed two-stroke engine and uses.
At present, domestic and international all kinds of internal-combustion engine is continued to use separated type piston ring groove structure always, as a vapour Jiefang brand motor car engine, generally travel 30,000 li, Second Automobile Works's Dongfeng brand motor car engine, 80,000 li of general strokes, cylinder piston is heavy wear just, cause piston ring gap to increase, therefore, produce a series of adverse consequencess: piston ring gas leakage.Engine power sharply descends, and lubricant oil is contaminated in the machine.The exhausting air befouling environment, the firing chamber seals in machine oil and combustion deposits occur, hot wire electric current, spark plug or diesel fuel nozzle cisco unity malfunction or the like.Must reprocess motor and carry out the boring cylinder, change piston and piston ring.
The purpose of this utility model is in order to solve the problem of above-mentioned existence, to change traditional irrational piston ring groove structure, and design a kind of new internal combustion engine structure.
The technical solution of its piston new structure is: the three road compressions (or twice compression) of conventional piston structure are changed into widen compression together, hold two piston rings in the groove, and keep original scraper ring.In wherein the collar extension juxtaposition of two piston rings is packed groove into, block, reach the location interlocking, form excellent sealing, and the shaft axis of the shaft axis of locating stud and piston pin hole is perpendicular by locating stud.
Characteristics of the present utility model are, the sealability of motor is greatly improved, thereby generally can prolong more than 120,000 kilometers in power performance good working life that prolongs motor.In addition, because piston structure has been simplified, reduced manufacturing procedure, piston ring quantity reduces, saved raw material, for big-and-middle-sized internal-combustion engine, every motor is saved 3.5 yuan of raw material approximately, if calculate to produce 150000 motors per year, can economize on the use of funds every year 540000 yuan.
Below in conjunction with accompanying drawing structural principle of the present utility model is described in detail.
Fig. 1 internal combustion engine new structure schematic representation.
Fig. 2 piston ring outline drawing.
With reference to Fig. 1,1 piston has one compression and one frizing annular groove, annular groove intensity height.2,6 locating studs, 3.5 piston rings, 4 scraper rings.7 piston pin holes.Locating stud 2,6 is used for localization method plug ring 3,5, and piston ring 3 blocks the location by locating stud 6.Piston ring 5 blocks the location by locating stud 2.And the shaft axis of locating stud 2,6 should be perpendicular with the shaft axis of piston pin hole 7.This kind location can guarantee that cylinder wear is more even, avoids producing eccentric wear.Has good sealing property.
With reference to Fig. 2.Piston ring 3,5 all has collar extension b and matches with locating stud 2,6.Intersect (phase difference is 180) and locate interlocking with the collar extension b that reaches piston ring 3 and piston ring 5, the parameter of piston ring 3,5 is pressed the motor different model and is decided.
Claims (2)
1, a kind of internal combustion engine, by piston 1, piston ring 3,5, piston pin hole 7 compositions such as grade, it is characterized in that the compression on the piston 1 is single groove of widening, the collar extension b juxtaposition that holds two piston rings 3,5, two ring is packed in the groove, by locating stud 2,6 location interlockings.
2, internal combustion engine according to claim 1 is characterized in that the shaft axis of the shaft axis of locating stud 2,6 and piston hole 7 is perpendicular.
