Abstract
The invention provides an exhaust manifold for an exhaust gas recirculation (EGR) engine. The exhaust manifold comprises an air inlet flange, an air outlet flange, exhaust pipes and an EGR outlet pipe, wherein the EGR outlet pipe is arranged at the junction of the exhaust pipes; and a connection flange is arranged at one end of the EGR outlet pipe. Due to the adoption of the exhaust manifold, the pressure difference of the exhaust pipes caused by exhaust gas discharged by the EGR outlet pipe is avoided, fluctuation of exhaust pressure of the engine is reduced, and the stability of performance of the engine is improved.
Description
Technical field
The present invention relates to the component in the motor car engine, particularly a kind of gas exhaust manifold that is used for the EGR motor.
Background technique
The effect of gas exhaust manifold is the waste gas that compiles each cylinder of motor, avoids the exhaust phase mutual interference between each cylinder, and reduces exhaust resistance as far as possible, makes waste gas discharge cylinder as much as possible.EGR (exhaust gas recirculatioon) technology is that a part of waste gas that cylinder is discharged is got into intake manifold again through the EGR passage, and reallocation burns for each cylinder, reaches to reduce to discharge nitrogen oxide (NO in the gas
X) purpose.The enmgine exhaust of band EGR technology is that waste gas is derived from the wherein outlet pipe on the gas exhaust manifold at present, imports intake manifold through the EGR passage.Bring shunting action owing on outlet pipe, derive waste gas; Make the gas pressure in this outlet pipe that is connected with the EGR delivery line can be littler than the gas pressure in other a few cylinder outlet pipes; Cause motor bigger exhaust pressure fluctuation to occur, thereby influence the stability of engine performance.
Summary of the invention
The object of the present invention is to provide a kind of gas exhaust manifold of the EGR of being used for motor, derive the engine back pressure fluctuation that causes to reduce EGR waste gas.
The gas exhaust manifold that is used for the EGR motor according to the invention comprises inlet flange, the flange of giving vent to anger, outlet pipe, EGR delivery line, and the EGR delivery line is arranged on the outlet pipe concourse.
Be provided with adpting flange at EGR delivery line one end.
The present invention is through being arranged on the EGR delivery line concourse of outlet pipe; Make EGR when deriving waste gas; The gas pressure fluctuation that is brought can not act on separately in the outlet pipe, has avoided the difference of pressure between outlet pipe, thereby has strengthened the stability of engine performance.And improved the combustion characteristic of motor, reduced FT, thereby reduced NO in the motor combustion gas
