Abstract
The utility model relates to an engine exhaust manifold layout, in particular to an engine exhaust manifold structural layout, which is characterized in that: the dimension for the section of a header pipe (5) in a collection section is enlarged gradually from the end section of a first exhaust channel (1) towards the rear section of the engine; a second exhaust channel (2), a third exhaust channel (3) and a fourth exhaust channel (4) are arranged with same sectional area dimension and slide into the header pipe air channel via the internal side of the header pipe (5); the central line of the exhaust channel is arranged at the internal side of a header pipe central line (6) and is not in tangency with the header pipe central line; an oxide sensor mounting hole (7) is positioned on a subtype surface at the internal side of the header pipe between the fourth exhaust channel (4) and an exit flange (8); the exist flange (8) is connected to a flange at the transferring section of the catalyst via a three-point bolt (10); the three point of the bolt are distributed at the interval of 120 degree; a waste gas recycle passage mounting interface (8) is arranged over the header pipe between the fourth exhaust pipe and the exit flange of the header pipe. The utility model has the advantages that: compared with conventional design, with a gradually expanded header pipe, the utility model is able to reduce the mutual interface between the exhaust gas between different cylinders via the layout of the exhaust channel, which facilitates the casting and the assembly of waste gas recycle system. In addition, with compact structure, the utility model facilitates the energy saving and satisfies the requirements in exhaust regulations.
Description
Technical field: the utility model relates to the enmgine exhaust housing, is specially a kind of Engine Exhaust manifold Device.
Background technique: in-line four cylinder enmgine exhaust structural type is varied, mainly is divided into two kinds of mono-layer tube air flue and bimetallic tube air flues by the layout pattern of manifold.The mono-layer tube air flue is that four manifolds directly import a house steward (four unifications), and the bimetallic tube air flue is that per two air flues are one group, and (two-in-one) again pools together behind the remittance house steward separately respectively.The conventional engines gas exhaust manifold mainly adopts the cast iron materials casting, and modern motor is in order to satisfy the Abgasgesetz of increasingly stringent, and the gas exhaust manifold of stainless steel welding has obtained popularization.
Summary of the invention: the purpose of this utility model be to provide a kind of simple in structure, the volume that takes up space is little, parts are compact, solve the motor cast iron engine exhaust manifold device that engine exhaust ties up to the installation question of space when nervous.The purpose of this utility model is achieved in that it is made up of first air flue (1), second air flue (2), the 3rd air flue (3), the 4th air flue (4), the Duan of compiling house steward (5), house steward's center line (6), lambda sensor mounting hole (7), outlet(discharge) flange (8), exhaust gas recirculation passage mounting interface (9).The Duan of compiling house steward (5) sectional dimension enlarges to the motor rear gradually from the terminal beginning of first air outlet flue (1), is the flaring type Duan of compiling house steward; Second air flue (2), the 3rd air flue (3), the 4th air flue (4) air flue are the uniform section size, among the inboard slick and sly camber line of the Duan of compiling house steward (5) (11) the incision Duan of the compiling house steward (5), its center line is in house steward's center line (6) inboard, and is not tangent with house steward's center line (6); Lambda sensor mounting hole (7) is arranged on the inboard mold joint of the house steward place between the 4th air flue (4) and the outlet(discharge) flange (8); Outlet(discharge) flange (8) adopts 3 bolts (10) to be connected with catalyst converter group section flange, and 3 are 120 degree and distribute; Exhaust gas recirculation passage mounting interface (9) has been arranged in house steward top between the 4th air flue (4) and house steward's outlet(discharge) flange (8); First air flue (1) is that one is connected with second air flue (2), the 3rd air flue (3), the 4th air flue (4), the Duan of compiling house steward (5), house steward's center line (6), lambda sensor mounting hole (7), outlet(discharge) flange (8), exhaust gas recirculation passage mounting interface (9).The utility model advantage is: this arrangement compact structure, saved cabin space, and this scheme has reduced the weight of car load, helps energy saving, reaches emission regulation demands.
Description of drawings: Fig. 1 is the utility model structural configuration schematic representation, and Fig. 2 arranges schematic representation for the utility model outlet(discharge) flange.
Embodiment: the Duan of compiling house steward (5) sectional dimension enlarges to the motor rear gradually from the terminal beginning of first air outlet flue (1), is the flaring type Duan of compiling house steward; Second air flue (2), the 3rd air flue (3), the 4th air flue (4) air flue are the uniform section size, among the inboard slick and sly camber line of the Duan of compiling house steward (5) (11) the incision Duan of the compiling house steward (5), its center line is in house steward's center line (6) inboard, and is not tangent with house steward's center line (6); Thereby reduce the phase mutual interference between each cylinder exhaust.Lambda sensor mounting hole (7) is arranged on the inboard mold joint of the house steward place between the 4th air flue (4) and the outlet(discharge) flange (8); Help casting.Outlet(discharge) flange (8) adopts 3 bolts (10) to be connected with catalyst converter group section flange, and 3 are 120 degree and distribute; Exhaust gas recirculation passage mounting interface (9) has been arranged in house steward top between the 4th air flue (4) and house steward's outlet(discharge) flange (8); First air flue (1) is that one is connected with second air flue (2), the 3rd air flue (3), the 4th air flue (4), the Duan of compiling house steward (5), house steward's center line (6), lambda sensor mounting hole (7), outlet(discharge) flange (8), exhaust gas recirculation passage mounting interface (9), helps gas exhaust manifold casting and exhaust gas recirculation assembling.The utility model is compared with conventional design, and this gas exhaust manifold arrangement belongs to flaring type house steward, and air flue is arranged the phase mutual interference can reduce between each cylinder exhaust, helps casting the assembling with gas recirculation system; Compact structure, help energy saving, reach emission regulation demands.
