Abstract
The utility model provides an improved structure for the tail end of the automobile engine, which is composed of a preposition tube drilled with a plurality of small holes and an outer sleeve tube whose diameter is bigger than that of the preposition tube. The outer sleeve tube is sheathed in the preposition tube; the rear part of the outer sleeve tube backwards extends for a section; the extended section is provided with a fan impeller. Therefore, when the automobile moves forward, the outer sleeve tube sucks the fresh cold air from the front side, and the fan impeller jointly acts the function of sucking the waste gas in the silencer and the air cylinder, which cause the burning in the air cylinder to be complete; therefore, the goal of achieving the oil saving, improving the output, reducing the contamination, reducing the carbon deposit in the air cylinder and prolonging the service life is achieved.
Description
The utility model belongs to the automobile internal machine technology.
The waste gas of motor car engine behind baffler, from the tailpipe to the atmosphere in.Because pipeline, baffler are to the mobile resistance that exists of waste gas, cause the back segment exhaust of each release unclean, residual exhaust gases is many in the cylinder, back pressure is high, this makes combustible gas incomplete combustion in the interior next work cycle of cylinder, both wasted fuel, influence power, increase the pollutant in the waste gas, even cause carbon deposit in the cylinder, accelerated wear test and scrap.A kind of improved tail pipe structure is arranged recently, form by two layers of sleeve pipe: preceding pipe and rear sleeve, its utilizes the helical blade be fixed in the rear sleeve to make waste gas through the effect of out-of-date generation vortex, and from the effect of the fresh cold air of rear sleeve front end inspiration outside, reaches the purpose of alleviating the problems referred to above.
Task of the present utility model provides a kind of further improved tail pipe structure, strengthen in the tail pipe pumping action and cooling action to waste gas, burn more fully in the cylinder thereby make, reach fuel-economizing, improve and to exert oneself, to reduce pollution, and the purpose that reduces carbon deposit, prolongs cylinder and piston working life.
Task of the present utility model be achieved in that tail pipe by one in tube wall, rear portion preposition pipe and diameter of being drilled with a plurality of apertures form greater than its outer sleeve.The latter is enclosed among the former, the rear portion is also extended one section backward; The two also welds with supporter supports; The outer sleeve front end make horn mouth in case when automobile advances inspiration fresh cold air and make waste gas cooling step-down, and afterbody is had reducing slightly so that the waste gas speedup is sprayed; After having a blast fan to be contained in preposition pipe in the outer sleeve, it is both by rotation that the high pressure exhaust gas of each release leading portion stream impacts, again in this release, back segment plays the suction exhaust to waste gas.
Such tail pipe has stronger pumping action to the waste gas in front baffler and the cylinder, makes the interior toxic emission of cylinder more thorough, and this has just guaranteed that combustible gas can burn more fully in the next work cycle.
It is axial sectional views of first embodiment that this specification has 2 width of cloth accompanying drawing: Fig. 1; Fig. 2 is the axial sectional view of another embodiment.
Below in conjunction with Fig. 1 first embodiment is elaborated: ［ 1 ］ is the female thread of preposition pipe ［ 3 ］ front end among the figure, and it is connected with the baffler (not shown); ［ 6 ］ be in the preposition pipe, the aperture at rear portion; ［ 8 ］ be the tubaeform of preposition pipe outlet port; ［ 2 ］ be the horn mouth of outer sleeve ［ 5 ］ front end; ［ 15 ］ be the reducing of outer sleeve afterbody; ［ 4 ］ be that thin plate (uniform along 120 ° of circumference) is supported in two groups each 3 of the front and back of being welded between preposition pipe and outer sleeve; ［ 11 ］ be blast fan, be contained on the axle ［ 13 ］, axially fixing by circlip ［ 12 ］; ［ 10 ］ be the rolling bearing of two band seal closures, they use high temperature lubricating grease lubrication; ［ 9 ］ be to support the antero posterior axis bearing ［ 7 ］ of impeller and two groups of dunnages of ［ 14 ］, every group by form each and bearing support, outer sleeve welding along 120 ° of 3 uniform thin plates of circumference; The center cone form is made in the place ahead of front-end bearing pedestal ［ 7 ］, and the vertex of a cone forward.Outer sleeve is clamped and is suspended on the chassis with the clamp (not shown).
It between preposition pipe and the outer sleeve is several (being depicted as 4 among the figure) and the swash plate (or spiral plate) of the axis angle degree of pipe that second embodiment (Fig. 2) and first difference are to be supported on, be welded between two pipes, make waste gas and cool air mixing, make air-flow blow the blade of impeller ［ 11 ］ from tilted direction simultaneously.For more effectively promoting impeller, the gradient of swash plate orientation should with the opposite orientation of blade skew.Preceding half section of every swash plate is preferably bored some apertures ［ 17 ］.
