Abstract
The utility model relates to a piston and a combined air ring of an internal combustion engine. The utility model is characterized in that the piston is only provided with an air ring groove and an oil ring groove, an upper and a lower piston rings are embedded in the air ring groove, and the openings of the upper and the lower rings are staggered. The utility model changes three air ring grooves of the original piston into one air ring groove. The sealing property is improved, the wear of the cylinder jacket is reduced, the service lives of the piston, the piston ring and the cylinder jacket are prolonged, and the power is added. The internal combustion engine of the utility model is used for a motorcar, and can make the motorcar have high speed and oil consumption saving.
Description
The utility model relates to a kind of internal combustion engine, piston ring.
Present internal combustion engine generally has three road compressions, one oil ring groove, each embedding one piston ring in three roads.Owing to there are three road compressions to exist, the 3rd piston ring that closes on oil ring groove has lubricant oil, first road then lubricant oil is then few,, influence sealing big to barrel wear, make piston, piston ring, cylinder sleeve weak point in working life, after a period of time, must change piston, rering at internal combustion engine, cylinder sleeve must the boring cylinder.
The purpose of this utility model is at above-mentioned piston, the existing problem of piston ring, is intended to design that a kind of barrel wear is little, good airproof performance, long service life, the internal combustion engine that can improve power, piston ring.
The purpose of this utility model realizes in the following manner, and internal combustion engine, Combined gaseous ring have compression 1, oil ring groove 2 on the piston, the embedded piston ring with opening of compression.Compression is that there is spacer ring 3 in groove central authorities together, and the upper and lower piston ring of Combined gaseous ring is embedded in the spacer ring upper and lower, and the ring opening staggers, and is added with diaphragm seal 5 in the middle of the lower piston ring.
The utility model is described in detail in detail with reference to the accompanying drawings.
Fig. 1 piston structure schematic representation.
Fig. 2 upper piston ring structural representation.
Fig. 3 lower piston ring structure schematic representation.
The utility model is with three road compressions on the original piston, and one oil ring groove changes one compression 1 into oil ring groove 2, improved the lubricating condition of top compression ring groove, barrel wear is reduced, increase sealing, improved the working life of piston, piston ring, cylinder sleeve.
Combined gaseous ring is made of the diaphragm seal 5 on upper and lower piston ring and the lower piston ring, and upper and lower ring opening staggers, and forms the imperforation compression ring, has improved sealing, has blocked the gas leakage that produces from opening.After blocking opening, improved air pressure, strengthened explosive force, also had simultaneously gas and leak the down opening of ring from the opening of the last ring interior circle by ring, for this reason, the utility model is adding a diaphragm seal on the ring down.
Also have a groove 4 on the piston, alleviated the weight of piston, make piston motion laborsaving, increased power.
The utility model is because the annular groove number reduces, and surface of contact reduces, and piston weight reduces, and has improved sealing, has increased power, has prolonged working life.The utility model is with east wind 140-47 vapour, diesel-oil vehicle, and test trip 40,000 km play speed, quickens soon, and climbing power is strong, and fuel-economizing is nearly 20%, and motor is estimated to use 300,000 km-50, ten thousand km, with respect to former stroke 110,000 km, improve working life 3-5 doubly, effect is obvious.It is all local uses of power source that the utility model is suitable for the internal-combustion engine.
Claims (2)
1, internal combustion engine, Combined gaseous ring, compression (1), oil ring groove (2) are arranged on the piston, the embedded piston ring of compression with opening, it is characterized in that compression is together, there is spacer ring (3) in groove central authorities, the upper and lower piston ring of Combined gaseous ring is embedded in the spacer ring upper and lower, and the ring opening staggers, and is added with diaphragm seal (5) in the middle of the lower piston ring.
2, piston according to claim 1, Combined gaseous ring is characterized in that also fluted (4) on the piston.
