Abstract
A novel swirl chamber for an internal combustion engine comprises an upper swirl chamber body and a lower swirl chamber body, wherein three or two connecting passages are arranged on the lower swirl chamber body; and the novel swirl chamber is communicated with a main combustion chamber through the connecting passages. Through the adoption of the novel swirl chamber, the mixing of fuel gases is more complete, so as to achieve the purposes of controlling the emission of the internal combustion engine and reducing oil consumption.
Description
Technical field
The present invention relates to a kind of internal-combustion engine turbulence chamber.
Background technique
Internal-combustion engine (diesel engine, petrol engine and other gas engine) is China's major impetus machinery, and there are direct spray type and non-direct spray type (eddy cell type, pre-burning cell-type etc.) in its firing chamber.Wherein swirl chamber diesel occupies critical role in Chinese national economy; As power such as automobile, tractor, agricultural water pump, reaper, small engineering machinery, spitkits; Be widely used in industry-by-industries such as traffic, agricultural, industry; Nearly 8,000,000 of Annual output is the tangible characteristic and the advantage of China's internal combustion engine development.
In order to adapt to the strict demand of Abgasgesetz, some new trends have appearred in the development of internal-combustion engine and development, and the most significant trend is exactly satisfying under the emission performance prerequisite up to standard, how to improve economic performance.As far as single-cylinder engine,, can only realize through improving, improve original oil supply system and combustion system owing to relate to manufacture cost.Existing traditional swirl combustion cell structure is mostly for hanging bell, by about two bodies form, the upper body is hemisphere and cylindrical combination, lower body is cylindrical inserting.The connecting passage of vortex chamber and main combustion chamber (also claiming the main jet hole) design is on inserting.In order to improve starting performance, the type that has also is designed with the starting aperture on inserting.The connecting passage (main jet hole) of existing traditional vortex chamber and main combustion chamber is single passage (single spray orifice), and its channel cross-section shape and size size is different because of type, and the internal-combustion engine oil consumption is higher.
Summary of the invention
For overcoming the above-mentioned deficiency of existing internal-combustion engine turbulence chamber, the present invention provide a kind of can
Reduce the internal combustion engine turbulence chamber of oil consumption.
The technological scheme that the present invention solves its technical problem is: a kind of internal combustion engine turbulence chamber; Form by upper body, vortex chamber and vortex chamber's lower body; Described vortex chamber lower body is provided with three or two connecting passages, and described vortex chamber communicates with main combustion chamber through described connecting passage.
Further, described connecting passage has three, and three connecting passages are arranged in delegation.Further, in three connecting passages, two connecting passages on both sides are about the center line symmetry of middle connecting passage.
Perhaps: described connecting passage has three, and three connecting passages are arranged in Pin Zixing.
Perhaps: described connecting passage has two, and two connecting passages are arranged in delegation.
Further, the cross section of said connecting passage is shaped as circle, ellipse, long-round-shape or square.
Further, the longitudinal section center line of said connecting passage is 20o ~ 70o with the angle of the vertical center line of inserting.
Further, the longitudinal section center line of said connecting passage is 50o with the angle of the vertical center line of inserting.
Further, also offer Starting Hole on the described vortex chamber lower body.
During internal combustion engine, the gas in the compression stroke, getting into turbulence chamber through connecting passage has three strands or two strands of air-flows, with the fuel oil premixing that sprays into turbulence chamber; During expansion stroke, eddy current stronger premixed gas in turbulence chamber center portion passes one of them connecting passage, faces the piston head guiding gutter of main combustion chamber, forms main eddy current; Meanwhile, also have the part combustion gas in the vortex chamber, pass remaining connecting passage, form two secondary eddy current,, thereby reach the controlling combustion engine discharging, reduce the purpose of oil consumption so the more traditional vortex chamber of combustion gas mixing is more complete facing to piston head valve pit.
Beneficial effect of the present invention is: combustion gas mixing is more complete, thereby reaches the controlling combustion engine discharging, reduces the purpose of oil consumption.
Description of drawings
Fig. 1 is a sectional view of the present invention.
Fig. 2 is that the A of Fig. 1 is to view.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain.
With reference to Fig. 1, Fig. 2, a kind of internal combustion engine turbulence chamber is made up of upper body, vortex chamber 1 and vortex chamber's lower body 2, and described vortex chamber lower body 2 is provided with three or two connecting passages 3, and described vortex chamber communicates with main combustion chamber through described connecting passage 3.In the present embodiment, described connecting passage 3 has three, and three connecting passages 3 are arranged in delegation, and in three connecting passages, two connecting passages on both sides are about the center line symmetry of middle connecting passage.The longitudinal section center line of said connecting passage 3 is 20o ~ 70o with the angle of vertical center line inserted, and is 50 ° in the present embodiment, and also 30 °, 40 ° etc. certainly all is suitable numerical value within 20o ~ 70o scope.In the present embodiment, also offer Starting Hole on the described vortex chamber lower body.
During internal combustion engine, the gas in the compression stroke, getting into turbulence chamber through connecting passage has three strands of air-flows, with the fuel oil premixing that sprays into turbulence chamber; During expansion stroke, eddy current stronger premixed gas in turbulence chamber center portion passes middle connecting passage, faces the piston head guiding gutter of main combustion chamber, forms main eddy current; Meanwhile, also have the part combustion gas in the vortex chamber, pass the connecting passage on both sides, form two secondary eddy current,, thereby reach the controlling combustion engine discharging, reduce the purpose of oil consumption so the more traditional vortex chamber of combustion gas mixing is more complete facing to piston head valve pit.
Certainly, three connecting passages also can be arranged in Pin Zixing.Connecting passage also can only be provided with two, and two connecting passages are arranged in delegation.
The shape of the cross section of said connecting passage can be circle, ellipse, long-round-shape or square etc., and the shape and size size is different because of type.Also offer Starting Hole 4 on vortex chamber's lower body described in the present embodiment.
