Abstract
An intake module, especially for internal combustion engines, having at least one intake duct, in which the intake duct has at least two induction tube openings; at least one induction tube opening of the intake duct having an unvarying cross section leading to the internal combustion engine, and at least one other induction tube opening of the same intake duct being connected to the internal combustion engine via a rotary valve.
Description
~1687~8 INTARE MODULE FOR AN INTERNAL COMBUSTION ENGINE
Background of the Invention The invention relates to an air induction module or intake module, especially for internal combustion engines with at least one air intake duct.
An intake module of this general type is known, for example, from German Patent Application No. DE 4,032,250.
If it is desired to use induction modules of this kind in passenger automobiles, for example, it is disadvantageous that throughout the entire working cycle they have a rotary valve in the flow cross section, which causes flow losses.
It is also disadvantageous that tolerance problems occur due to the required overall length of the rotary valve.
It is possible to make the entire component from cast metal. This, however, is for one thing expensive to manufacture. For another thing it would increase the weight.
It would be desirable to have an improved intake module - of the foregoing kind which is inexpensive and easy to manufacture, easy to install and reliable in operation.
Summary of the Invention It is the aspect of the invention to provide an intake module which comparatively alleviates the problems of the prior art.
It is also an aspect of the invention to provide an intake module which is inexpensive to manufacture, easy to install, and reliable in operation.
` 216~798 Another aspect of the invention is to provide an intake module which minimizes flow losses and tolerance problems due to the presence of a rotary valve.
These and other aspects of the invention are achieved by providing an intake module for an internal combustion engine comprising at least one intake duct, wherein the intake duct is provided with at least two induction tube openings; at least one induction tube opening of the intake duct having an invariable cross section leading to the internal combustion engine, and at least one other induction tube opening of the same intake duct being connected to the internal combustion engine via a rotary valve.
In accordance with the present invention, the induction section of the intake module has at least two induction tube openings, and at least one induction tube opening of the induction section leading through an invariable or unchangeable cross section into the internal combustion engine, and at least one other induction tube opening of the same induction section being connected by a rotary valve to the internal combustion engine.
Under operating conditions in which only part of the induction tube cross section is needed, there is no additional part to interfere with the flow resistance, and this promotes reduced fuel consumption. Under operating conditions in which an expanded cross section is necessary, the cross-sectional arèa is optimally adjusted by means of the rotary valve.
One advantageous embodiment provides for the rotary valve to be disposed in the flange of the intake module.
This arrangement facilitates assembly as well as maintenance of the rotary varlve units. Also, this embodiment makes it possible to use various material combinations between the cylinder head, the flange and the rotary valve.
In accordance with the invention it is also advantageously possible for the rotary valve to be symmetrical about its longitudinal axis. This symmetrical 216~7~8 configuration results in advantages both with respect to manufacture and to the operation of the rotary valve.
Another advantageous embodiment provides for the rotary valve to be mounted floatingly. With regard to the matter of installation tolerances, and to the generation and transmission of noise, this embodiment results in clear advantages.
An advantageous embodiment is achieved if the rotary valve and/or the air intake module is composed of a plastic (i.e, synthetic resin) material. Decided weight and cost advantages are obtained by manufacture from a plastic.
These and other features of preferred embodiments of the invention, in addition to being set forth in the claims, are also disclosed in the specification and/or the drawings, and the individual features each may be implemented in embodiments of the invention either individually or in the form of subcombinations of two or more features and can be applied to other fields of use and may constitute advantageous, separately protectable constructions for which protection is also claimed.
Brief Description of the Drawings The invention will be described in further detail hereinafter with reference to illustrative preferred embodiments shown in the accompanying drawings in which:
Figure 1 is a top plan view of an intake module according to the invention;
Figure 2 is a section taken along the line A - A of Figure l;
30Figure 3 is a sectional view through the rotary valve hous ing;
Figure 4 is a top view seen in the direction of arrow X in Figure 2;
Figure 5 shows an embodiment in which a rotary valve is mounted in a floating manner; and , , 21687i~8 Figure 6 shows an embodiment in which a rotary valve is mounted spherically.
Detailed Description of Preferred Embodiments The intake module, as shown in Figure 1, comprises induction tube 1, flange 2 and vacuum box 3. The integration of the rotary valve 4 is illustrated in section both in Figure 2 and in Figure 3 in the position in which it is installed in flange 2. The operation of rotary valve 4 may be actuated and controlled either electromagnetically, hydraulically or by means of a vacuum control unit. In a preferred embodiment, the operation of at least rotary valves is controlled by means of coupled push rods and pull rods.
The symmetry of the valve with respect to its longitudinal axis is particularly visible in Figure 3. The rotary valve 4 regulates only the flow cross section of one of the two induction tube openings 5, so that the other induction tube opening 6 can advance the combustion mixture without anything that increases resistance to flow.
The separation of the corresponding induction tube openings 5 and 6 in the flange area can be seen in Figure 3.
This separation of the openings as well as the required opening and closing of the rotary valve assures optimum combustion in any state of operation, as well as a resultant reduction of the fuel consumption. Thus it is possible to use lean mixtures in all operating states.
The use of plastic as the material of the air intake manifold duct 1, flange 2 and rotary valve 4 reduces the weight as well as the manufacturing costs.
As shown in Figure 5, the floating support of the rotary valve 4 is accomplished by means of a lubricant-doped plastic sleeve B on the rotary valve shaft 7 as well as the associated O-ring 9, which is contained in a recess in the housing.
~1~87~8 Figure 6 illustrates another embodiment in which the rotary valve shaft 7 is rounded, and the material of the shaft/bearing sleeve combination is chosen from lubricant-doped plastics.
The foregoing description and examples have been set forth merely to illustrate the invention and are not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
