Abstract
A diesel engine part - double cylinder boost diesel engine pavilion type air outlet pipe is composed of an air outlet pipe and a 1st exhaust manifold and a 2nd exhaust manifold, which are communicated with the air outlet pipe at the same time; wherein, the exhaust inlet end of the two exhaust manifolds is provided with a mounting flange respectively, and the end surface interlocking the exhaust outlet of the air outlet pipe and the booster inlet of the exhaust outlet is provided with a mounting flange, as well as the internal chamber of the air outlet pipe is provided with a separator plate communicating with the air outlet pipe. The separator plate divides the air outlet pipe into two exhaust hollow chambers which are not blow-by with each other, and the two exhaust manifolds are communicated with the exhaust hollow chambers respectively, and the two exhaust manifolds are all the big well-rounded arc elbow pipes. The height of the inlet and outlet of the air outlet pipe-namely the height from the plane center of the mounting flange at the end of the exhaust manifold exhaust inlet to the plane of the mounting flange at the end of the air outlet pipe exhaust outlet H is 76 - 78mm. the air outlet pipe discharges the waste gas of the two exhaust manifolds at both sides of the separator plate respectively, and is free of blow-by, so that the booster efficiency impact due to the overheat of the exhaust temperature of the engine can be avoided.
Description
Technical field:
The utility model relates to a kind of diesel engine accessory, relates in particular to a kind of outlet pipe of two cylinder supercharged diesel engines.
Background technique:
Outlet pipe is the important spare part of supercharged diesel engine, the two cylinder pressure-increasing machine outlet pipes of Sheng Chaning have the following disadvantages in the market: 1, exhaust is same outlet between first cylinder and second cylinder, the time exhaust waste gas of two cylinders is scurried mutually in engine low rotation speed, make motor row temperature too high and influence the performance of efficiency of turbocharger; 2, outlet pipe not enough garden of angle, garden transition from the gas exhaust manifold to the outlet pipe when design is sliding, and the engine exhaust resistance is increased, and it is obstructed to be directed at engine exhaust easily, and the row's of causing temperature is too high; 3, the excessive height from outlet pipe exhaust entrance center to outlet pipe exhaust outlet plane, on the one hand the total height of motor is increased, influence motor overall structure and attractive in appearance, exhaust tubing consumption is increased, cause the increase of cost of production, nor be beneficial to the energy that makes full use of waste gas.The patent No. is that 200420078802 utility model patent discloses a kind of diesel engine pulse type gas exhausting pipe, this model utility is improved the outlet pipe of four cylinder four-stroke diesel engine, it links to each other the 1st, 4 arms, 2nd, 3 arms are continuous converges for total mouthful with exhaust then, its in twos the arm concourse cut water is set, can avoid answering back to of blast air, reduce the loss of exhaust energy.But this outlet pipe just is provided with cut water at the arm concourse that links to each other in twos, and 2, the relief opening of 3 arms remains and communicates, and the concourse of 1,4 arms is half waist cut waters, still can not well solve the problem that waste gas is scurried mutually.This outlet pipe is mainly used in the cylinder four-stroke diesel engine in addition, is unsuitable for big, discontinuous, the uneven two cylinder supercharged diesel engines of working of operational vibration.
The model utility content:
The purpose of this utility model is to provide a kind of more optimized structure, the material consumption is low, reliability is high, can effectively solve the two cylinder supercharged diesel engine separated type outlet pipes that the waste gas of two cylinders is scurried mutually, and the exhaust that above-mentioned prior art exists is smooth, row's temperature is too high, two cylinder waste gas are scurried the problem that efficiency of turbocharger is brought into play that influence mutually to overcome.
The technological scheme that the utility model is taked is: a kind of two cylinder supercharged diesel engine separated type outlet pipes, comprise outlet pipe and first gas exhaust manifold that is connected with outlet pipe simultaneously, second gas exhaust manifold, the exhaust entrance end of two gas exhaust manifolds has mounting flange respectively, the exhaust outlet of outlet pipe has mounting flange with the end face that the pressurized machine import connects, the dividing plate that one perforation outlet pipe is arranged at the inner chamber of outlet pipe, this dividing plate is divided into mutually not two exhaust cavities of gas blowby with outlet pipe, and first gas exhaust manifold and second gas exhaust manifold are connected with two exhaust cavities respectively.The thickness of this dividing plate is 2～6mm.
Further improvement of the utility model is: first gas exhaust manifold of described garden arc and the knuckle of second gas exhaust manifold are R80～R90.
Another improvement of the present utility model is: the import and export of described outlet pipe height---planar central to the height H on outlet pipe exhaust outlet end mounting flange plane that is discharge manifold exhaust entrance end mounting flange is 76～78mm.
Owing to taked above technological scheme, the two cylinder supercharged diesel engine separated type outlet pipes of the utility model are compared with existing two cylinder supercharged diesel engine outlet pipes, have following beneficial effect:
1, owing to has one outlet pipe is divided into two dividing plates of the exhaust cavity of gas blowby not mutually at the inner chamber of outlet pipe, the waste gas of first gas exhaust manifold and second gas exhaust manifold is discharged from two exhaust cavities of dividing plate both sides respectively, can not scurry mutually, can effectively avoid engine exhaust temperature too high and influence the performance of efficiency of turbocharger.
2, the circular arc degree of first gas exhaust manifold of this outlet pipe and second gas exhaust manifold is bigger, is R80～R90 rounding off, can reduce the engine exhaust resistance, makes engine exhaust smooth and easy, reduces row's temperature.
3, reduced the whole height of outlet pipe, shortened the length of outlet pipe, the import and export of outlet pipe of the present utility model height---the planar central that is discharge manifold exhaust entrance end mounting flange is to the height H on outlet pipe exhaust outlet end mounting flange plane only about 77mm, reduced about 30mm than original 107mm, both improve overall structure and aesthetic property, reduced the materials consumption of outlet pipe again.Be beneficial to simultaneously and make full use of exhaust energy.
Below, the technical characteristics to the utility model two cylinder supercharged diesel engine separated type outlet pipes is further described in conjunction with the accompanying drawings and embodiments.
