Abstract
The utility model relates to a five rings piston of gasoline engine. Because the prior art has the disadvantages of poor piston guide, great friction, poor air-tightness and low cylinder pressure, the five rings piston of gasoline engine is provided with the advantages of simple structure, guide improvement, small friction, high air-tightness and high cylinder pressure. The technique scheme adopted is that a guiding ring 5 is provided in the groove on the lower part of the outerwall of a piston 6; an upper gas ring (1), a middle gas ring (2), a lower gas ring (3) and an oil ring (4) are in turn provided in the groove of the outerwall from up to down.
Description
One, technical field
The utility model relates to piston of gasoline engine, especially a kind of petrol engine five rings piston.
Two, background technique
Number of patent application 03233396.X discloses " a kind of petrol engine Fourth Ring piston " patented technology, adopts three road compression rings with the oil ring structure, exists deficiencys such as piston guide is poor, friction is big, poor air-tightness, the cylinder pressure is on the low side.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, the petrol engine five rings piston that can improve guiding, friction is little, tightness good, the cylinder pressure is high.
The technological scheme that the purpose of this utility model adopted is, includes and is equipped with compression ring, middle compression ring, lower air ring, oil ring in the piston outer wall groove from top to bottom successively, is equipped with guide ring in its piston outer wall lower channel.
The utility model compared with prior art has following advantage:
1, can improve petrol engine compression guidance quality, tightness, cylinder be pressed rise the mixed gas fully burning of more gasifying, reduce harmful matter in the discharging waste gas, be beneficial to environmental protection piston.
2, increase the length that leads in the piston motion, make piston and casing wall impact swing and reduce,, can increase the service life to reduce wearing for piston.
3, owing to impact to reduce, cylinder is pressed and is improved, and burning has improved engine power and efficient fully, and fuel saving reaches the purpose of fuel-economizing.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is the utility model structural representation.
Among the figure: compression ring 3-lower air ring 4-oil ring 5-guide ring 6-piston among the last compression ring 2-of 1-
Five, embodiment
As shown in drawings, in the piston 6 outer wall grooves compression ring 1, middle compression ring 2, lower air ring 3, oil ring 4, guide ring 5 are housed successively from top to bottom.
Claims (1)
1, a kind of petrol engine five rings piston includes and is equipped with compression ring (1), middle compression ring (2), lower air ring (3), oil ring (4) in piston (6) the outer wall groove from top to bottom successively, it is characterized in that being equipped with guide ring (5) in piston (6) the outer wall lower channel.
