Abstract
The utility model relates to a sealing type combustion engine with polygon cylinder rollers, which comprises a piston, rollers, a cylinder, etc., wherein, the piston is arranged in the cylinder which is an octagon which is centrosymmetrical. The piston is a dodecagon which is centrosymmetrical. The periphery of the top part of the piston is provided with the rollers which are slipped into the slot in an omega shape, and the cone apex angles of the cones of the two contiguous rollers are complementary. The sealing type combustion engine with polygon cylinder rollers changes sliding friction between the wall of the cylinder of the existing internal combustion engine and a piston ring to rolling friction between the cylinder wall and the rollers. Thus, the utility model reduces abrasion, increases the power by 15%-20%, and saves the fuel by 50%. An automobile does not need to carry out major repair when running for ten million km.
Description
The utility model relates to a kind of polygonal cylinder roller sealed type internal-combustion engine.
The piston of existing internal-combustion engine is a cylindrical body, and cylinder is a cylindrical hole, and does sliding friction by piston and piston ring and cylinder wall.Because sliding friction will consume certain effective merit, also consumable and weakened the merit that internal-combustion engine is done simultaneously.This frictional loss makes the gap of piston and casing wall become big thereupon, the casing wall distortion, the sealability variation, compression ratio also degenerates in succession, and at the reciprocating engine knock of generation in a flash sound, gas leakage string oil, power sharp fall, problems such as difficult starting are comed one after another, and therefore must carry out the internal-combustion engine overhaul.
The purpose of this utility model solves the existing in prior technology problem with regard to being, and a kind of frictional force that provides is little, power is high, the polygonal cylinder roller sealed type internal-combustion engine of long service life, fuel saving and 10,000,000 kilometers no overhauls of automobile running.
The purpose of this utility model realizes by following measure.A kind of polygonal cylinder roller sealed type internal-combustion engine, comprise piston, pin-and-hole, cylinder etc., piston places in the cylinder, cylinder is centrosymmetric Octagon, piston is centrosymmetric dodecagon, roller is housed around the top of piston, and roller is filled in the groove of Ω shape and the cone-apex angle complementation of adjacent two roller cones.
The projection of described piston axis direction becomes the shape of compensation mutually with the cylinder cross section, and piston and cylinder are centrosymmetric Octagon.
The middle part of described roller is a cylindrical body, and two ends are that cone and cylindrical length equate with the length of side of piston.Roller is filled in the groove of Ω shape, and roller surface is given prominence to piston 0.5-2 millimeter scope.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model plan view.
Fig. 2 is the utility model plan view.
Plan view when Fig. 3 is centrosymmetric Octagon for the utility model piston.
Among the figure: 1, cylinder 2, roller 3, piston 4, pin-and-hole
As shown in Figure 1 and Figure 2, piston 3 places in the cylinder 1, and cylinder 1 is centrosymmetric Octagon, and piston 3 is centrosymmetric dodecagon.When the projection of piston 3 axial directions became the shape of compensation mutually with cylinder 1 cross section, piston 3 and cylinder 1 were centrosymmetric Octagon (as shown in Figure 3).Pin-and-hole 4 is located on the piston 3, around the top of piston 3 roller 2 is housed, and roller 2 contacts with cylinder wall, seals.Roller 2 is filled in the groove of Ω shape, within the outstanding piston 0.5-2 millimeter scope in roller 2 surfaces, and the cone-apex angle complementation of adjacent two rollers, 2 cones.The middle part of roller 2 is a cylindrical body, and two ends are cone, and cylindrical length equates with the length of side of piston 3.
Owing to adopt said structure,, change into the rolling friction between cylinder and roller, thereby make friction factor reduce and reduce wearing and tearing greatly the sliding friction between the cylinder wall of existing internal-combustion engine and piston, the piston ring.
The utility model compared with prior art, it is little to have frictional force, power height, the advantages such as long service life. Use the utility model can improve power 15-20%, fuel savings 50%, 1,000 ten thousand kilometers no overhauls of running car are a kind of internal combustion engines with promotional value.
