    摘要: Cette installation (10) comprend un réacteur de dénitrification (12) contenant un catalyseur structuré (14) à travers lequel des fumées à traiter (1) passent pour être dénitrifiées. L'installation comprend également un conduit de by-pass (16), qui est pourvu de registres (24, 26), et par lequel les fumées à traiter contournent le réacteur de dénitrification sans passer par le catalyseur lorsque les registres sont ouverts. Afin que l'installation puisse décolmater efficacement le catalyseur, tout en présentant un encombrement minimal, le conduit de by-pass est accolé au réacteur de dénitrification, en en y étant raccordé, en amont du catalyseur, par une ouverture d'entrée (20), tandis que des moyens de décolmatage (30) sont prévus pour projeter un fluide (2), à la fois, tangentiellement à la surface libre amont (14A) du catalyseur, pour en retirer des poussières (P), et vers l'ouverture d'entrée du conduit de by-pass pour évacuer ces poussières par le conduit de by-pass conjointement avec au moins une partie des fumées à traiter.

    摘要: The invention relates to an exhaust manifold for an internal combustion engine, having at least one exhaust pipe (18) and a flange (12) which can be fastened to an engine block of the internal combustion engine. On the side facing away from the engine block, the flange (12) is provided with a channel (22) which is connected to a fluid line (26) and which is in fluid connection with the interior of the exhaust pipe (18) via a lateral opening (28) in the exhaust pipe (18). The fluid pipe (26) opens into the channel (22) on the side of the flange (12) that faces away from the engine block.

    摘要: An internal combustion engine is capable of improving cleaning efficiency by preventing an increase in the temperature of the exhaust gas to lessen the deterioration of the catalyst. The internal combustion engine 1 includes a convergent section 32, a divergent section 33, and a branch section 21. The branch section 21 branches a shock wave 35, propagating in a downstream direction at a higher velocity than exhaust gas 36 flowing into an exhaust path 16 from a combustion chamber 10 when an exhaust valve 9 is opened, from a portion of the exhaust path 16 which is upstream with respect to the divergent section 33, and propagates the shock wave 35 back to the exhaust path 16. The exhaust gas 36 is caused to pass the convergent section 32 and to collide against the shock wave 35 between the branch section 21 and the divergent section 33, thus to increase the pressure of the exhaust gas 36 in the convergent section 32. Such exhaust gas 36 is caused to pass the divergent section 33 to generate a new shock wave 35b and thus to decrease the temperature of the exhaust gas. A catalyst 41 of an exhaust cleaning device 40 is provided in a portion of the exhaust path 16 which is downstream with respect to the divergent section 33.

    摘要: A secondary air supply system includes a CPU, a first air supply pipe, a second air supply pipe, a first shut-off valve and a second shut-off valve. One ends of the first air supply pipe and the second air supply pipe are connected to an air cleaner box and the other ends thereof are connected to an exhaust port. The CPU controls opening/closing of the first shut-off valve and the second shut-off valve based on a state of an engine. The first shut-off valve and the second shut-off valve are selectively opened by the CPU, so that air in the air cleaner box is supplied to the exhaust port through the first air supply pipe or the second air supply pipe.

    摘要: This invention is to provide a tappet clearance adjusting cover (51) coupled with a secondary air valve (4). The tappet clearance adjusting cover (51) is disposed on a cylinder head (5) of an engine. The secondary air valve (4) includes a recessed element (42) and a cap (43) which jointly form a receiving space receiving therein a one-way valve. The recessed element (42) is provided with an inlet pipe (45) interposed between the cap (43) and the tappet clearance adjusting cover (51). By disposing the secondary air valve (4) on the tappet clearance adjusting cover (51) and arranging the inlet pipe (45) between the cap (43) and the tappet clearance adjusting cover (51), with the one-way valve (46) received in the receiving space of the secondary air valve, heat dissipation can be improved while the one-way valve (46) is protected against premature deterioration and carbon deposition caused by a high-temperature exhaust gas from the cylinder head. Thus, reliability as well as a service life of the one-way valve (46) is effectively increased.

    摘要: An internal combustion engine (1) is provided in which a secondary air passage (30) is located above a combustion chamber (3). A water jacket (36) is provided between the secondary air passage (30) and an exhaust passage (6) that communicates with the combustion chamber (3). Further, a water jacket (35) is provided between the secondary air passage (30) and an intake passage (4) that communicates with the combustion chamber (3). The water jacket (35, 36) is formed so as to circumscribe the secondary air passage (30). Accordingly, the exhaust gas flowing in from the exhaust passage (6) and staying in the secondary air passage (30) can be cooled down by the coolant flowing through the water jacket (35, 36).

    摘要: An engine includes a cylinder (7), an exhaust port (12), an exhaust valve (78), a secondary air supply pipe (73), and an electromagnetic valve (34). The electromagnetic valve (34) is opened in a predetermined time period after a point in time when a lift amount of the exhaust valve reaches about half a maximum value during a time period in which an opening of the exhaust port is opened. This causes air to be supplied from a secondary air supply pipe (73) to the exhaust port (12).

    摘要: The present invention relates to an arrangement (1) in a secondary air injection-system for an internal combustion engine, a secondary air injection system comprising such an arrangement (1) and an automotive vehicle comprising such a secondary air injection system. The arrangement comprises means (4) for receiving an airflow (5) from a secondary air injection pump- At the downstream side of the airflow receiving means (4) is arranged a shut-off valve means (3) for selectively passing on or restricting said airflow (5). A flexible interconnecting means (6) is arranged to receive the airflow (5) and pass it on to at least two reed-type non-return valves (7a, 7b) arranged to substantially only allow an airflow in the downstream direction. At the downstream side of each respective reed-type non-return valve (7a, 7b) a means for communicating any airflow (5) passed there through to an associated exhaust bank (2a, 2b) of the internal combustion engine.
