Abstract
The utility model relates to an air inlet manifold structure for automotive engines, which comprises a constant pressure cavity (2) for the air inlet manifold. Air flows into the constant pressure cavity (2) through an air cleaner and a back end of an engine and then respectively into four horizontal air passages (4) through a section of vertical air passage (3) with a shrinking cross section. The utility model is characterized in that air smoothly flows into these four air passages (4) from the constant pressure cavity at an accelerated speed to ensure air entry consistency for each air passage. In addition, higher reinforcing ribs (7) are arranged along centerlines of air passages 1(14) and 4(17). A reinforcing rib (8) at an intersection between a horizontal section (4) and a vertical section (3) of the air passage forms a right-angled triangle with a horizontal air passage and a vertical air passage as two right-angle sides. A reinforcing rib (6) on the air passage 2 and 3 is lower, thus ensuring intensity during molding and mechanical processing and slightly increasing weight of the air inlet manifold. One end of the air inlet manifold adjacent to a cylinder cap is provided with a water passage to preheat incoming air and accelerate even mixing of fuel and air.

Description of drawings: Fig. 1 looks schematic representation for the utility model structural principle master; Fig. 2 looks schematic representation for the utility model structural principle right side; Fig. 3 is the utility model structural principle schematic rear view.
Embodiment: there are shorter stiffening rib (6), high stiffening rib (7), tabular stiffening rib (8) in the below at the air flue (4) of the vertical air flue (3) of convergent, level, tabular stiffening rib (8) is positioned at bend place that the vertical air flue (3) of convergent is connected with the air flue (4) of level and is connected with high stiffening rib (7), and the vertical air flue (3) of suction port (1), pressure stabilizing cavity (2), convergent, the air flue (4) of level, water route (5), short stiffening rib (6), high stiffening rib (7), tabular stiffening rib (8) overall shape are reclinate hunchbacked shape; Be provided with high stiffening rib (7) at 1 air flue (14), 4 air flues (17) air flue upper edge air flue center line, tabular stiffening rib (8) in vertical air flue (3) intersection of the air flue (4) of level and convergent present with level and vertically air flue be the right-angled triangle of right angle side, and that middle 2 air flues (15), 3 air flues (16) are gone up short stiffening rib (6) is shorter, intensity when having guaranteed casting and machining also makes the weight of air inlet air flue that increase is just arranged slightly.The air inlet air flue has water route (5) near cylinder cap one end, and air inlet is had pre-heat effect, has quickened fuel oil and has mixed with the even of air.Because intake manifold is longer, form overhang, for proof strength, be provided with the support of reinforing function in the below of intake manifold pressure stabilizing cavity (2), simultaneously at the standoff installation base in the intake manifold pressure stabilizing cavity outside.
The utility model principle: whole motor tilts 50 ° to exhaust side, in order to reduce the whole height of motor, makes 4 air flue horizontal arrangement after the installation.Air-flow is from pressure stabilizing cavity, and the arm air flue of process convergent enters in the cylinder head.Since the water route of motor be arranged in intake duct below, inevitably to the air inlet heating, therefore outside 4 air flues, all be furnished with the water route from the 1 air flue outside, each air flue is heated evenly.On the water route, be provided with two cooling-water temperature sensor interfaces, an air inlet pressure sensor interface and a crankcase ventilation connecting-tube nozzle mounting platform are arranged on pressure stabilizing cavity.Because intake manifold is longer, form overhang, for proof strength, the support of reinforing function has been arranged in the arranged beneath of intake manifold pressure stabilizing cavity, outside the intake manifold pressure stabilizing cavity, cast out the installation base of support simultaneously.Whole motor tilts 50 ° to exhaust side, and 4 intake ducts of the intake manifold after the installation are horizontal arrangement, help reducing the whole height of motor; The overall shape of intake manifold is reclinate hunchbacked shape, the length of the intake manifold that both extended, and the while does not influence the height of motor again; Air-flow is from pressure stabilizing cavity, and the arm air flue of process convergent enters in the arm air flue of one section level, and benefit is the speed that increases air-flow, makes full use of the inertia inflation; Make structure seem compact more.In the arranged beneath of intake manifold pressure stabilizing cavity the support of reinforing function has been arranged, cast out the installation base of support simultaneously in the intake manifold pressure stabilizing cavity outside, made overhang that long air flue forms reduce the influence of structural strength.The utility model working procedure is: air-flow enters into pressure stabilizing cavity through air-strainer from suction port, and the arm air flue of process convergent enters in the arm air flue of one section level, is done slightly to enter into cylinder head after the heating by the hot water in the water route.The corresponding pressure signal of air inlet pressure sensor collection of the corresponding temperature signal of cooling-water temperature sensor collection of water route sensor interface, installation, the installation of air inlet pressure sensor interface is passed to the electronic control unit of motor simultaneously, so that electronic control unit is made corresponding judgement.
