A tube junction is produced having at least two inlets and an outlet, and at least one bend between the two inlets by providing a forging die with a first recess contoured to hold a bent tube piece. A second recess opens into the first recess and, terminates in a moveable counterpunch. A tube piece having two inlets is bent to bring the two inlets into positions relative to each other generally similar to relative positions of the inlets in a finished tube junction. The bent tube piece is placed within the forging die, and pressurized internally to bulge the tube piece wall into the second recess and form a neck for the outlet. Motion of the counterpunch away from the first recess is controlled as the neck forms under pressure in the second recess.

Method for producing an exhaust gas manifold for a multi-cylinder engine

Emission control system for internal-combustion engines

Process for the acoustic examination of monoliths for damage and device

A method and apparatus for cleaning of a soot filter in the exhaust line of a diesel engine with a combustion chamber placed in front of the soot filter where a fuel nozzle and an adapted electrical ignition mechanism is built in thereby enabling an after burning of the exhaust without secondary air. The exhaust in the combustion-chamber is mixed with the fuel, which is injected through the fuel nozzle, and ignited by an ignition-device with the existing portion of the unburned oxygen. The hot exhaust effects the burn down of the accumulated soot in the soot filter.

Device for catalytically purifying exhaust gases from a combustion engine and process for implementing such device. A porous catalyst body bears against the inner walls of a casing above a winding of a metal wire netting. The annular space between the catalyst body (1) and the casing (2) is obturated by means of an annular seal made of a non-inflammable ceramic fibre material, so that such fibre material is pressed inside and between the windings of the wire netting (3). Further, the wire netting is wound with a superposed layer of fibre material.

Device for catalytically purifying exhaust gases for a combustion engine

The invention relates to a manifold on a six-cylinder in-line engine for the conduction of the exhaust gases between the engine block and the exhaust piping, the manifold comprising pipe lines which are formed by half shells consisting of sheet metal and which are welded together in their common separation plane said half shells also forming wall portions between said pipelines to provide support against thermal stresses.

Manifold on a six-cylinder in line engine

An engine exhaust manifold includes two sheet metal half shells welded together to form exhaust passages and adjacent webs for rigidity and absorption of vibrations.

Manifold on an internal combustion engine

A sheet metal housing for a metal monolithic body for an automobile. Noses are impressed in the sheet metal to engage the facing ends of the monolithic catalyst body.

Catalytic converter having monolith mounting means therein

Apparatus for catalytic purification of internal combustion gases wherein a cylindrical catalyst body is housed in an external housing between which a shock absorbing resilient envelope is interposed. A seal ring is provided at least one end of the body extending outwardly from the frontal edge into abutment with the housing.
