The invention is a piston internal-combustion engine with in-combustion chamber combustible mixed gas flow gathering ring, simple in structure and manufacturing process and characterized by that: it has an in-combustion chamber combustible mixed gas flow gathering ring which comprises top, outer circle, bottom, basal body and inner wall and can be made of cast iron, or stainless steel, or alloy, or composite. Thus, the combustible mixed gas has good mixing uniformity and combustion completeness, which can increase effective power of internal-combustion engine and reduce pollutant discharge.
Description
Affiliated technical field
The present invention relates to a kind of piston IC engine with combustion chamber combustable mixing gas flow collection ring, especially a kind of combustion in IC engine chamber interior between combustion engine cylinder head bottom surface, piston head and body end face is installed the internal-combustion piston engine that is provided with combustable mixing gas flow collection ring.
Background technique
At present, its combustion-chamber shape of the internal-combustion piston engine of known present application generally all needs to be designed to be able to satisfy the shape of fuel combustion performance.The uniformity that internal-combustion piston engine inflammable gas gas mixes and the completeness of burning will directly influence the useful horsepower output of internal-combustion engine and the spatter property of toxic emission.If can make inflammable mixture in the firing chamber obtain very high flowing velocity and produce strong air-flow, burning mixture can obtain the good mixing uniformity under strong air-flow effect, improve combustion efficiency and the useful horsepower of internal-combustion engine and the completeness of fuel combustion of fuel, and reduce the discharging of pollutant.
Summary of the invention
Mix the deficiency of inhomogeneous and incomplete combustion for the inflammable mixture that overcomes existing internal-combustion piston engine, the invention provides a kind of piston IC engine with combustion chamber combustable mixing gas flow collection ring, can improve the uniformity and the combustion completion of internal-combustion engine inflammable mixture.
The present invention solves the scheme that its technical problem takes, a kind of piston IC engine with combustion chamber combustable mixing gas flow collection ring is that inner the installation in order to the uniformity of improving inflammable mixture and the ring type of combustion completion in a kind of firing chamber between combustion engine cylinder head bottom surface, piston head and body end face put internal-combustion piston engine.
Piston IC engine with combustion chamber combustible mixing gas collection ring is installed between piston-type internal combustion engine cylinder lid bottom surface and the body end face, and by below the cylinder head bottom surface, body, combustion chambers of internal combustion engines has been formed in the above space of conflux ring and piston head.
Piston IC engine with combustion chamber combustable mixing gas flow collection ring is characterized in that the internal-combustion piston engine setting is equipped with, and forms chamber combustable mixing gas flow collection ring by ring top, ring cylindrical, ring bottom, matrix and ring inwall.Ring top, ring cylindrical, matrix and ring bottom are mainly used in the fixing of ring and support, and the effect of ring inwall is a flow characteristic of improving flammable mixed gas, i.e. the direction of gas flow, the form of speed and air-flow.As making air-flow produce strong eddy current or turbulent flow by the shape of selecting the ring inwall.
The shape of the combustable mixing gas flow collection ring cylindrical of piston IC engine with combustion chamber combustable mixing gas flow collection ring should be chosen according to the shape of combustion chambers of internal combustion engines, as rectangular ring, circular ring, keystone ring, elasticity fracture ring, cylindrical raised ring, cylindrical leg ring, special-shaped ring etc.
The base shape of chamber combustable mixing gas flow collection ring can be chosen according to the free space shape of firing chamber, as the rectangular ring of routine, trigonometric form ring, ladder type ring, shaped rings etc.
The inner wall shape of piston IC engine with combustion chamber combustible mixing gas collection ring will directly determine shape, mixing uniformity, speed and the form of inflammable mixture air-flow, as adopt the rectangle inwall, trapezoidal inwall, the inner wall shape of isoline transition can produce strong turbulence, adopt the circular arc inwall, shrinkage expansion shape inwall can produce strong stable air whirl.
The manufactured materials of piston IC engine with combustion chamber combustible mixing gas collection ring should have good heat resistance, impact toughness and mechanical strength.Can select gray cast iron for use, stainless steel, various alloys and composite material etc.
The firing chamber of internal-combustion piston engine that combustable mixing gas flow collection ring is installed is by below the combustion engine cylinder head bottom surface, body, conflux ring internal face, the above space of piston-top surface is formed, the inwall radial dimension that is installed in the conflux ring between cylinder head and the body less than with the cylinder head inwall of conflux loop wire connection part and the radial dimension of body inner wall of cylinder, so when compression stroke begins, gas is during from cylinder barrel one side direction cylinder head one side flow, conflux ring internal face upside is an extending section, and the inwall downside is the compressing section.Gas flow is during to the downside compressing section of conflux ring inwall, since air-flow path pass through reducing of area, the gas that flows can be quickened suddenly and stacking energy, when gas during by conflux ring inwall upside extending section again because the increase of gas by area, the speed and the energy of air accumulation are discharged suddenly, make gas produce strong air whirl or turbulent flow,, help the perfect combustion of inflammable mixture to promote the mixing uniformity of inflammable mixture.
When the expansion space stroke of internal-combustion piston engine begins, inflammable mixture burning and violent the expansion, the gas of High Temperature High Pressure is during from cylinder head one side direction cylinder barrel one side flow, the upside of conflux ring internal face is the compressing section, downside is an extending section, air current flow is to conflux ring upside compressing section, because reducing suddenly by area, air-flow is compressed and quickens, when air flow stream is crossed conflux ring downside extending section, gas flow speed is accelerated, energy is further discharged, with the combustion efficiency that improves flammable mixed air and the useful horsepower of internal-combustion engine.
The invention has the beneficial effects as follows, piston IC engine with combustion chamber combustable mixing gas flow collection ring structure and manufacturing process are simple, the adoptable material of chamber combustable mixing gas flow collection ring is extensive, design and installation are simple and easy and do not need internal-combustion engine is made large-scale modification and repacking, and available material has cast iron, stainless steel, various alloy and composite material etc.Be provided with and install the internal-combustion engine system of piston IC engine with combustion chamber combustible mixing gas collection ring, inflammable mixture has good mixing uniformity and combustion completion, can increase the useful horsepower of internal-combustion piston engine and reduce the discharging of pollutant.
