摘要： An exhaust gas reaction chamber has an inner chamber surrounded and encompassed by an outer chamber, and a "U" shaped pipe(9) extends through both chambers and has a single feed port(11) positioned within the inner chamber. Both ends of the pipe(9) receive exhaust gases discharged through two paired exhaust passages(9a, 9b) discharging through a single port(11). A thick wall housing(22) surrounds the reaction chamber(10) but is spaced from the thin metal walls(14a, 15a) which form the reaction chamber(10).

摘要： An exhaust manifold for a multi-cylinder engine employs three concentric exhaust reaction chambers. Exhaust inlet pipes convey hot exhaust gases from the exhaust ports of the engine directly into the innermost reaction chamber. The concentric reaction chambers extend substantially at right angles to the exhaust inlet pipes which are parallel. Concentric tubes encircle the exhaust inlet pipes and each is connected to one of the concentric exhaust chambers. The flared portions of the exhaust inlet pipes engage in surface contact with the correspondingly flared portions of the tubes. End members having concentric shoulders engage cylindrical shells which defines the exhaust reaction chambers. Bolted spacers are positioned substantially midway of the length of the shells and space them in concentric fashion.

摘要： An exhaust manifold for a multi-cylinder internal combustion engine is provided with preliminary oxidation reaction chambers, each of which receive exhaust gases from exhaust port liners each serving a pair of adjacent cylinders of different exhaust timing. These preliminary oxidation reaction chambers each communicate downstream with a main oxidation reaction chamber subdivided into a plurality of concentric subchambers. The subchambers enclose the preliminary oxidation reaction chambers and exhaust gas inlet pipes. Combustion of unburned hydrocarbons (HC) is accomplished in the preliminary oxidation reaction chambers, and the exhaust gases are maintained at relatively high temperature and retained for a sufficient period of time in the subchambers to accomplish combustion of the unburned carbon monoxide (CO).

摘要： An internal combustion engine exhaust manifold has a lateral opening through which exhaust gases may heat intake mixtures for the engine. The exhaust manifold comprises a thick wall housing enclosing a thin wall liner, the liner having inlet tubes receiving exhaust gases from the engine exhaust ports, and having a discharge pipe. The liner is secured in the lateral opening of the housing so that its inlet tubes and discharge pipes may move by differential expansion. Internally threaded sockets fixed to the liner extend into the housing opening and the sockets project through clearance openings in a stationary support ring fixed to the housing opening. Threaded fasteners are received in the sockets and a heat shield is mounted within the liner to prevent exposure of the ends of the threaded fasteners to the hot exhaust gases within the liner.

摘要： An engine exhaust reaction chamber system having an inner exhaust reaction chamber surrounded by an outer exhaust reaction chamber, the system having a partition plate means for preventing exhaust flow bypass through the outer exhaust reaction chamber positioned within the annular space of the outer exhaust reaction chamber. A guide plate may also be positioned within the annular space of the outer exhaust reaction chamber in order to separate the outer exhaust reaction chamber into first and second outer exhaust reaction chamber passages. Further, a middle exhaust reaction chamber may be positioned between the inner and outer exhaust reaction chambers, the middle exhaust reaction chamber also being provided with a partition plate in order to prevent exhaust flow bypass through the middle exhaust reaction chamber and being provided with a guide plate separating the middle exhaust reaction chamber into first and second middle exhaust reaction chamber passages.

摘要： An exhaust reaction chamber assembly is provided for a four-cylinder in-line internal combustion engine having two pairs of exhaust ports, the ports in each pair being closely spaced. The assembly includes an exhaust manifold having two preliminary reaction chambers each connected to receive exhaust gases from one of said pairs of exhaust ports, respectively. A main reaction chamber is provided within the exhaust manifold and two curved passages each connect one of the preliminary reaction chambers to the main reaction chamber, respectively, each passage curving for about 90 DEG . The passages have aligned outlets so that the exhaust gases from each passage are directed toward the other passage. The gases are then directed perpendicular to the inlet in an elongated direction through the main reaction chamber. In one embodiment, the aligned outlets are spaced apart within the main reaction chamber, and in a modification the aligned outlets are formed in a single pipe having a side window opening into the main reaction chamber. A restriction may be placed between each passage and the preliminary reaction chamber to which it is connected, in order to increase residence time.
