Abstract
An intake-air duct 5 for a combustion engine of a motor vehicle within an engine compartment is covered by a bonnet 3 and has a radiator, 2 past which the intake-air duct 5 is conducted in the longitudinal direction of the vehicle. When the bonnet 3 is closed, the intake-air duct 5, in its front region which is situated upstream, is partially bounded directly by the bonnet 3 and a transverse beam 4 (radiator cross member) which is present on the body side above the radiator, 2. Downstream, the air intake duct may comprise two circumferentially closed intake pipes 6.
Description
1 Intake-air duct for a combustion enQine of a motor vehicle 2333270 The
invention relates to an intake-air duct for a combustion engine of a motor vehicle within an engine compartment covered by a bonnet and having a radiator, past which the intake-air duct is conducted in the longitudinal direction of the vehicle, and having a transverse beam running above the radiator.
For reasons to do with space, in the engine compartment of a motor vehicle it is frequently difficult to conduct the intake-air duct past the radiator. There is generally insufficient space in particular at the sides.
For reasons to do with space and simplifying assembly, DE 41 23 360 A l, DE 39 01 658 C2, DE-AS 1 066 887 and JP 07-21 50 75 A have already disclosed integrating regions of the intake-air duct into the bonnet and fastening the connecting regions between the bonnet and regions situated fixedly below the bonnet tightly via interconnected seals.
The present invention is concerned with the problem of providing an intake duct region conducted past the radiator using means which are structurally as simple and economical on space as is possible.
According to the present invention there is provided an intake-air duct for a combustion engine of a motor vehicle within an engine compartment covered by a bonnet and having a radiator, past which the intake-air duct is conducted in the longitudinal direction of the vehicle, and having a transverse beam running above the radiator, including: in a subregion extending in the flow direction the flow space of the intake-air duct is bounded by the bonnet and the transverse beam, when the bonnet is closed, vertical boundary walls which are connected tightly to the transverse beam or which originate from the latter, tightly adjoin the bonnet via a compressible seal, an intake-air duct which is circumferentially closed by its own walls is present downstream of the transverse beam.
The invention is based on the concept of using, in a bonnet region which is situated at the front in the longitudinal direction of the vehicle and in which there is little space for conducting an intake-air duct past a radiator because of the bonnet being 2 pulled down as far as is possible, the transverse beam (so-called radiator cross member) which is situated above the radiator, and also the bonnet itself as boundary walls for the intake duct. In this arrangement, vertical boundary walls can be produced by an additional part fitted to the transverse beam. This additional part forms at least one circumferentially closed intake-air flow duct downstream. When the bonnet is closed, the vertical flow duct walls are sealed with respect to the bonnet by a seal. This seal consists of a soft, strongly compressible material.
The advantage of such an intake-air conducting means according to the invention is that the free space which is situated between the transverse beam above the radiator and the bonnet can be used, in the direction of the vertical axis, entirely as intake duct area. The soft seal which seals the vertical boundary walls of the flow duct with respect to the bonnet enables a functional compression travel when the bonnet is closed. Because of this necessary compression travel of the bonnet a fixed, upper boundary wall of the intake-air duct could not be situated vertically below the closed bonnet without a clearance. Rather, an unused free space into which the bonnet can briefly dip during the closing process has to be left there. In the design according to the invention this free space can be used entirely as flow duct region.
An advantageous preferred embodiment of the invention is now described and illustrated systematically in the drawing, in which Fig. 1 shows a perspective view of an upstream front region of an intake- air duct to be bounded by the bonnet, Fig. 2 shows a side view of the intake-air duct.
In an engine compartment 1 of a motor vehicle a radiator 2 is installed transversely to the longitudinal axis of the vehicle. The front boundary of the engine compartment 1 is a hinged bonnet 3 which is indicated in Fig. 2 merely by dash-dotted lines.
Above the radiator 2 there is located a transverse beam 4 which is fastened on the body side and which is also called a radiator cross member.
That forked region of an intake-air duct 5 which is situated upstream is fastened on this transverse beam 4. Downstream, this intake-air duct 5 is designed in the form of two circumferentially closed intake pipes 6.
In that forked part of the intake-air duct 5 which is situated upstream, 3 the intake air flows in in accordance with the plotted arrows. The forked part is bounded vertically at the bottom by the transverse beam 4 and vertically at the top by the bonnet 3. The vertical walls in the forked part of the intake-air duct 5 are sealed with respect to the bonnet 3 by a circumferential seal 7. This seal 7 is only shown in Fig. 2 while it is not illustrated in Fig. 1. This seal 7 is expediently connected fixedly to the upper, vertical edge of the forked part of the intake-air duct 5.
By means of the design according to the invention of that front region of the intake-air duct which lies upstream, the free space, which has previously lain unused between the transverse beam 4 fitted above the radiator 2 and the bonnet 3, is used in an extremely rational manner to save on space.
