Abstract
A kind of novel piston ring is not changing internal combustion engine cylinders and piston structure, mainly the thickness of original ring is divided into more than two or two, and the opening of these two rings is merged into a ring symmetrically, is contained in the same piston ring groove.Load onto this ring, can improve power, oil consumption obviously descends, and reduces noise, and carbon deposit is few, starts easily.
Description
The present invention relates to a kind of compression ring of internal-combustion engine piston ring.Originally the piston ring of internal-combustion engine is installed although the opening of multiple tracks compression ring intersects owing to there is an opening to cause gas leakage, has gas leakage all the time, and this gas leak phenomenon brings fuel and the power loss that can't save to motor.
Purpose of the present invention proposes a kind of novel piston ring, under the situation that does not change cylinder body and piston structure, loads onto this ring, can increase power, saves oil consumption, reduces noise, and carbon deposit is few, improves advantages such as compression ratio.
When work done was compressed, seal compression was higher than more more for its " assembly gas " according to internal-combustion engine in the present invention, and work doing efficiency also designs with regard to high more principle.
The present invention takes the thickness of an original ring is divided into more than two or two, and the opening of these two rings is merged into a ring symmetrically, is contained in the same piston ring groove.The assembling that all uses the same method of the head-end compression ring and second ventilation ring or multiple tracks compression ring had so both kept the opening performance of former ring, did not also need original external form redesign has been solved because the opening of original ring causes oil consumption and power loss.
Accompanying drawing 1 is the scheme of installation of novel piston, and accompanying drawing 2 is original piston ring schematic representation, and accompanying drawing 3 is schematic representation of novel ring, and accompanying drawing 4 is the novel ring scheme of installations of gaining in strength, and accompanying drawing 5 is to strengthen the ring schematic representation.Accompanying drawing 6 strengthens the monolithic schematic representation of ring.
Describe structure, installation method and the preparation process of this novel piston ring in detail below in conjunction with accompanying drawing.
(1) piston rod in accompanying drawing 1 accompanying drawing 4, (2) piston, (3) oil ring, (4) novel piston second road compression ring, (5) novel piston top compression ring, (6) cylinder block.
(4) (5) of accompanying drawing 1 are second road and the top compression rings that generally need not the novel piston ring that strengthens, its structure such as Fig. 3.Accompanying drawing 2 is structural representations of original piston ring, (4) (5) in the accompanying drawing 4 are two roads and the head-end compression rings that strengthens novel ring, its structure is shown in accompanying drawing 5 and accompanying drawing 6, the novel ring of this enhancing mainly uses in heavy duty, from it structure as can be seen, because the periphery of compression ring takes chamfering method to make, thereby do not increase the friction of ring and casing wall.The material that the angular dimension of chamfering can encircle according to thickness, work done pressure size and the making of original ring determines, shown in accompanying drawing 5 accompanying drawings 6.
The Manufacturing material of novel piston can be according to the cylinder block material of internal-combustion engine, and watt level is selected original material for use, also can adopt the new process of new material powder metallurgy to make, and adopts different powder metallurgy proportioning sintering to form according to different internal-combustion engine models.Make piston ring with powder metallurgy, it is simple to have technology, the yield rate height, and quality is good, cost is low, is easy to advantages such as batch process.
Can be used for the making of original piston ring too with the new process of powdered metallurgical material making piston ring.
Claims (3)
1, a kind of piston gas ring is characterized in that the thickness of an original ring is made into more than two or two, and the opening of these two rings is staggered is merged into a ring, is contained in the same piston ring groove.
2, novel piston ring as claimed in claim 1 is characterized in that increasing the thickness of ring, and the periphery of ring is improved the intensity of ring with the method for chamfering and do not increased the friction of ring and casing wall.
