Abstract
Description
- This invention generally relates to exhaust gas recirculation (EGR) systems in internal combustion engines. More particularly, this invention relates to devices that connect an EGR apparatus to the exhaust manifold of a diesel engine.
- Diesel engines convert chemical energy from a fuel into mechanical energy. The fuel usually is petroleum-based. Most diesel engines compress air in a cylinder and then inject fuel into the cylinder for the compressed air to ignite. The ignited fuel generates rapidly expanding gases that actuate a piston in the cylinder. The piston usually is connected to a crankshaft or similar device for converting the reciprocating motion of the piston into rotational motion. The rotational motion from the crankshaft may be used to propel a vehicle, operate a pump or an electrical generator, or perform other work. The vehicle may be a truck, an automobile, a boat, or the like.
- Many diesel engines have an exhaust gas recirculation (EGR) system to reduce the production of nitrogen oxides (NOX) during the combustion process in the cylinders. The EGR system typically diverts a portion of the exhaust gases for mixing with air entering the engine for combustion. The exhaust gases generally lower the combustion temperature below the temperature where nitrogen combines with oxygen to form nitrogen oxides (NOX).
- To divert the exhaust gases, most EGR systems connect to the exhaust manifold of the engine. The exhaust manifold generally is an accumulation chamber above the cylinders that gathers the exhaust gases for expulsion from the vehicle. Many EGR systems have a pipe or other conduit that connects to the exhaust manifold. The pipe may divert the exhaust gases through a gas cooling device such as a heat exchanger prior to mixing the exhaust gases with the incoming air to the cylinders. The exhaust gases may have a temperature in the range of about 300° F. (149° C.) through about 1,500° F. (815° C.) during engine operation.
- In many EGR systems, the pipe or other conduit is connected to the exhaust manifold by bolting a flat connection surface on the pipe against a flat connection surface on the exhaust manifold. A gasket usually is placed between the connection surfaces. The flat connection may increase the assembly time and costs due to the dimensional variations of the pipe and other components in the EGR system. The flat connection may distort and leak from the higher temperatures, thermal cycling, and thermal expansion at the connection with the exhaust manifold.
- Some EGR systems use a pipe with a flexible element to reduce the assembly variation and thermal expansion from the connection with the exhaust manifold. The flexible element may increase the costs of the EGR system and may leak and fail from the higher temperatures and thermal cycling of the connection with the exhaust manifold.
- This invention provides a connection system for exhaust gas recirculation (EGR) in a diesel engine. The connection system presses surfaces on an EGR conduit and an exhaust manifold together. The connection system compresses a sealing strand between one of the surfaces and an inside surface of a groove formed in one of the surfaces.
- A connection system for exhaust gas recirculation (EGR) may have an EGR conduit, an exhaust manifold, and a sealing strand. The EGR conduit forms a first surface surrounding an inlet. The exhaust manifold forms a second surface surrounding an outlet. The sealing strand is disposed in a groove formed in one of the first and second surfaces. The groove has an inside surface. One of the first and second surfaces is a convex surface. The other one of the first and second surfaces is a concave surface. The first and second surfaces form a first seal. The stealing strand forms a second seal between the inside surface and one of the first and second surfaces.
- Another connection system for exhaust gas recirculation (EGR) may have an EGR conduit, an exhaust manifold, and a sealing strand. The EGR conduit forms a convex surface surrounding an inlet. The exhaust manifold forms a concave surface surrounding an outlet. The sealing strand is disposed in a groove formed in one of the convex and concave surfaces. The groove has an inside surface. The convex surface presses against the concave surface. One of the convex and concave surfaces compresses the sealing strand against the inside surface.
- A further connection system for exhaust gas recirculation (EGR) may have an EGR conduit, an exhaust manifold, and a sealing strand. The EGR conduit forms a concave surface surrounding an inlet. The exhaust manifold forms a convex surface surrounding an outlet. The sealing strand is disposed in a groove formed in one of the convex and concave surfaces. The groove has an inside surface. The concave surface presses against the convex surface. One of the convex and concave surfaces compresses the sealing strand against the inside surface.
- In a method for connecting an exhaust gas recirculation (EGR) conduit to an exhaust manifold, a concave surface engages a convex surface. The convex surface and the concave surface are clamped together. A sealing strand is compressed between an inside surface of a groove formed in one of the convex and concave surface surfaces and one of the convex and concave surfaces.

Theconnection system 100 includes an exhaust gas recirculation (EGR)conduit 102, anexhaust manifold 104 for the diesel engine, a sealingstrand 106, andbolts 108. TheEGR conduit 102 forms aconvex surface 110 surrounding aninlet 112 into theEGR conduit 102. TheEGR conduit 102 forms agroove 114 along the circumference of theconvex surface 110. Thegroove 114 has aninside surface 115. TheEGR conduit 102forms mounting bores 116 adjacent to theinlet 112. Theexhaust manifold 104 forms aconcave surface 118 surrounding anoutlet 120 out of theexhaust manifold 104. Theexhaust manifold 104forms mounting cavities 122 adjacent to theoutlet 120. During assembly, the sealingstrand 106 is disposed in thegroove 114. TheEGR conduit 102 is connected to theexhaust manifold 104. Theconvex surface 110 engages theconcave surface 118. Thebolts 108 are inserted through the mounting bores 116 and fastened into the mountingcavities 122. Thebolts 108 clamp theconvex surface 110 against theconcave surface 118 to form a first seal. Theconcave surface 118 compresses the sealingstrand 106 against theinside surface 115 of thegroove 114 to form a second seal. While a particular configuration is shown, theconnection system 100 may have other configurations including those with additional components. - The
EGR conduit 102 may be a tube or pipe for diverting exhaust gases to an EGR system in a vehicle. TheEGR conduit 102 may be an EGR cooler device such as a coolant-exhaust gas heater exchanger that uses the engine coolant to reduce the temperature of the exhaust gases. TheEGR conduit 102 may have other configurations. TheEGR conduit 102 may be made from cast iron or steel. Other materials may be used. - The sealing
strand 106 may have a rectangular, triangular, circular, or like cross-section. The sealingstrand 106 may have a thickness greater than the depth of thegroove 114. The sealingstrand 106 may have a smaller cross-section area than the cross-sectional area of thegroove 114. The sealingstrand 106 may have a variable cross-section.

The sealingstrand 106 may be made from a malleable material such as steel or copper. Other materials may be used. When assembled, the sealingstrand 106 is compressed against theinside wall 115 of thegroove 114 to form a seal between theEGR conduit 102 and theexhaust manifold 104. The sealingstrand 106 may conform to any irregularities on theconvex surface 110 or theinside surface 115. The sealingstrand 106 may trap carbon particles from the exhaust gases to seal any leaks that may develop. - The
groove 114 may be positioned at about the midpoint of the surface. Thegroove 114 may be positioned between the midpoint and either edge of theconvex surface 110 or theconcave surface 118. The position of thegroove 114 may vary between the edges of either surface. Thegroove 114 may have an essentially circular circumference. Thegroove 114 may have an elliptical or oval circumference. Theinside surface 115 of thegroove 114 may have an angular, circular, or like configuration. - The
bolts 108 may be essentially equidistant from each other. There may be two, three, or other multiples ofbolts 108. Other mechanical connection devices may be used to hold theEGR conduit 102 and theexhaust manifold 104 together. - The
convex surface 110 and theconcave surface 118 may have essentially matching profiles. Theconvex surface 110 andconcave surface 118 may have a spherical, parabolic, or like profile. Theconvex surface 110 and theconcave surface 118 may have profiles that connect the surfaces together along essentially the entire circumference of each surface when theconnection system 100 is assembled. Theconcave surface 118 may have a socket-like profile to receive theconvex surface 110. During assembly, theconvex surface 110 may be shifted, rotated, or otherwise repositioned in theconcave surface 118 to accommodate or reduce the effect of dimension variations when the EGR conduit is connected to other components in the EGR system or the diesel engine. When assembled, theconvex surface 110 presses against and forms a seal with theconcave surface 118. -
