Abstract
The utility model discloses an energy-saving piston, which comprises a piston body, C-shaped opening gas rings and a C-shaped opening oil ring, wherein five grooves are formed outside the upper end of the piston body, the four C-shaped opening gas rings and the C-shaped opening oil ring are respectively arranged in the grooves from top to down, staggered angles of the four C-shaped opening gas rings from top to down are respectively characterized in that the staggered angle between a first gas ring and a second gas ring is 180 degrees, the staggered angle between the second gas ring and a third gas ring is 90 degrees, the staggered angle between the third gas ring and a fourth gas ring is 180 degrees, the gas rings have effects of sealing, and the oil ring has an effect of lubrication. The energy-saving piston has the advantages of good sealing condition, complete combustion, low exhaust pollution, energy saving and environment friendliness, cylinder pressure is increased, oil consumption is reduced, and power is improved.
Description
Technical field
The utility model relates to a kind of piston, particularly a kind of energy-saving piston.
Background technique
Diesel engine has piston structure, and the sealed precision between cylinder and the piston is determining the sealability and the efficiency of energy utilization of machine, and the sealed precision of cylinder and piston depends on the assembling of piston gas ring.What the piston ring great majority that existing piston is joined adopted is the structure of an oil ring and two compression rings or an oil ring and three compression rings, such sealing structure poor performance, and expend the energy.
Summary of the invention
The purpose of the utility model is the problem that to have piston seal property difference now and expend the energy in order to solve, and a kind of energy-saving piston that can overcome above-mentioned shortcoming is provided.
The utility model is made up of piston body 1, C type opening compression ring 2 and C type opening oil ring 3, and outside, piston body 1 upper end offers five grooves 11, in the groove 11 by last under be respectively arranged with four C type opening compression rings 2 and a C type opening oil ring 3.
Described four C type opening compression rings 2 bicker degree that from top to bottom staggers is respectively: first compression ring and second compression ring bicker degree that staggers is 180 degree; Second compression ring and the 3rd compression ring bicker degree that staggers is 90 degree, and the 3rd compression ring and the 4th compression ring bicker degree that staggers is 180 degree.
The compression ring of the utility model plays the effect of sealing, and oil ring plays lubricated effect.
The beneficial effect of the utility model is: air-proof condition is good, and cylinder pressure increases, and burning consumes oil and reduces fully, and power improves, and exhaust pollution is little, energy-conserving and environment-protective.
