Abstract

Un sistema de recirculación de gases de escape y succión de aire (1, 2) para un motor diesel (30) que comprende: un conducto de succión (3, 4) que se provee para canalizar el aire aspirado de la atmósfera a por lo menos un cilindro (5) de dicho motor (30), donde el conducto de succión (3, 4) incluye un colector de admisión (3) y una línea de succión que está conectada al colector de admisión (3) que está posicionada corriente arriba de dicho colector de admisión (3), y un sistema de recirculación de los gases de escape (2) que se provee para introducir nuevamente en el conducto de succión (3, 4) una parte de los gases de escape procedentes de un tubo de escape (6) de dicho motor (30), donde dicho sistema de recirculación (2) comprende un conducto de recirculación de los gases de escape (8, 9, 10) que está instalado con una compuerta de salida (11) para dicha parte de los gases de escape que es apropiado que esté comunicada con el conducto de succión (3, 4). El colector de admisión (3) comprende una sección transversal de entrada (17) que tiene una primera área de tránsito de fluido para permitir la entrada en el colector de admisión (3) del aire proveniente de la línea de succión 4. El conducto de succión (3, 4) además comprende una sección transversal de conducto (18) que tiene una segunda área de tránsito de fluido que está situada corriente arriba de dicha compuerta de salida (11). El sistema de recirculación de gases de escape y succión de aire (1, 2) está caracterizado porque la segunda área de tránsito de fluido es un área invariante y reducida en comparación con la primera área de tránsito de fluido.An exhaust gas recirculation and air suction system (1, 2) for a diesel engine (30) comprising: a suction duct (3, 4) that is provided to channel the air drawn from the atmosphere to minus a cylinder (5) of said motor (30), where the suction duct (3, 4) includes an intake manifold (3) and a suction line that is connected to the intake manifold (3) that is positioned current above said intake manifold (3), and an exhaust gas recirculation system (2) that is provided to reintroduce a portion of the exhaust gases from a tube into the suction duct (3, 4) Exhaust (6) of said engine (30), wherein said recirculation system (2) comprises an exhaust gas recirculation duct (8, 9, 10) which is installed with an outlet gate (11) for said part of the exhaust gases that is appropriate to be communicated with the suction duct (3, 4). The intake manifold (3) comprises an inlet cross section (17) that has a first fluid transit area to allow entry into the intake manifold (3) of the air coming from the suction line 4. The intake duct suction (3, 4) further comprises a cross section of conduit (18) having a second fluid transit area that is located upstream of said outlet gate (11). The exhaust gas recirculation and air suction system (1, 2) is characterized in that the second fluid transit area is an invariant and reduced area compared to the first fluid transit area.
