For realizing above-mentioned purpose, the technological scheme that the utility model adopts is:

The automobile exhaust pipe of the described a kind of energy-saving and pollution-reducing of the utility model; Comprise the filtration constrictor; Said filtration constrictor one end is connected with gas exhaust manifold and reflow pipe; The said filtration constrictor the other end is connected with the exhaust port pipe, and said filtration constrictor inner chamber is provided with the honeycomb manifold and filters the interception pipe, and said reflow pipe has the function of Purge gas.

Further, the interception shell of said filtration interception pipe is fixedly connected on the filtration contraction shell that filters constrictor.

Further, said honeycomb manifold one end is fixed on the interception shell, another termination of said honeycomb manifold corresponding the outlet of gas exhaust manifold.

Further, the quantity of said gas exhaust manifold is four, and said four gas exhaust manifolds are the corresponding arrangement of square, and said reflow pipe places the central authorities of four gas exhaust manifolds.

Further, said honeycomb manifold wall is provided with a plurality of apertures.

Further, said honeycomb manifold passes the loudspeaker wall of interception shell, and said honeycomb manifold is welded on the loudspeaker outer wall of interception shell.

Further, said filtration interception pipe is horn-like.

After adopting said structure; The utility model beneficial effect is: the automobile exhaust pipe of the described a kind of energy-saving and pollution-reducing of the utility model; Comprise and filter constrictor, reflow pipe and gas exhaust manifold; Said filtration constrictor inner chamber is provided with the honeycomb manifold and filters the interception pipe, and said reflow pipe has the Purge gas function.When using the utility model, the gas of an engine emission part is discharged through filtering constrictor, reduces the discharge of harmful gases amount, has protected environment; The loudspeaker parietal layer that another part harmful gas is filtered the interception pipe stops, returns to oil cylinder after the inflow reflow pipe purifies and burns once more, has improved the motor thermal technology and has led and move rate density, reduces oil consumption.The utlity model has simple in structurely, be provided with rationally, advantage such as fabricating cost is low.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1; The automobile exhaust pipe of the described a kind of energy-saving and pollution-reducing of the utility model; Comprise and filter constrictor 2, the mouth of said filtration constrictor 2 one ends and gas exhaust manifold 4 is connected as a single entity along the wall welding along the mouth of wall and reflow pipe 5, and said filtration constrictor 2 the other ends are connected with exhaust port pipe 1; Said filtration constrictor 2 inner chambers are provided with honeycomb manifold 21 and filter interception pipe 22, and said reflow pipe 5 has the function of Purge gas; The other end of said gas exhaust manifold 4 is provided with welded plate 3, be convenient to car body in other parts be connected.

As shown in Figure 2, gas exhaust manifold 4 quantity of the utility model are four, and gas exhaust manifold 4 quantity are to confirm according to the engine cylinder number of motor vehicle.Said four gas exhaust manifolds 4 are the corresponding arrangement of square, and said reflow pipe 5 places the central authorities of four gas exhaust manifolds 4, and this is the optimal layout scheme of four gas exhaust manifolds 4 of the utility model, and concrete layout also needs decide according to the car load design proposal.

Like Fig. 3, shown in Figure 4, said honeycomb manifold 21 1 ends are fixed on the interception shell 221, said honeycomb manifold 21 another terminations corresponding the outlet of gas exhaust manifold 4, each is to honeycomb manifold 21 and the 4 corresponding connections of a gas exhaust manifold.The interception shell 221 of said filtration interception pipe 22 is fixedly connected on the filtration of filtering constrictor 2 and shrinks on the shell 23.

As shown in Figure 4; Said honeycomb manifold 21 walls are provided with the effect that a plurality of apertures 211 can play filtering noxious gas; Said honeycomb manifold 21 passes the loudspeaker wall of interception shell 221, and said honeycomb manifold 21 is welded on the loudspeaker outer wall of interception shell 221, and said filtration interception pipe 22 is horn-like; The loudspeaker wall of filtration interception pipe 22 effectively blocking harmful gas is directly discharged, and the harmful gas that is stopped flows into reflow pipe 5.Can establish air-strainer in the reflow pipe 5, the harmful gas that the loudspeaker wall of this spline filter interception pipe 22 stops filters in reflow pipe 5, and the gas after the filtration returns to oil cylinder.
