- the air intake device of internal combustion engines conventionally comprises an intake manifold, also called a distributor, which has the function of communicating the outlet of the air filter and the inlet of the various intake ducts provided in the engine cylinder head.
- the intake manifold conventionally has a body which is fixed on the cylinder head of the engine; this body generally comprises a large capacity distribution chamber also called plenum and several tukulures which leave this distribution chamber to supply air with combustion of each of the combustion chambers of the engine.
- the intake manifold of an internal combustion engine is generally connected to a greater or lesser number of vacuum sockets used to operate components as diverse as the braking system or Master Vac, EGR valve, fuel return valve fitted to the injection rail, systems for adding non-combustible substances or secondary combustible substances such as crankcase gases, fuel vapors from the canister or even the recirculated burnt gases, as well as the collector pressure measurement sensor.
- the pressure prevailing in the intake manifold, which is necessary for controlling the injectors, is in fact conventionally operated by means of an absolute pressure sensor connected by a flexible pipe of length suitable for a tapping opening into the chamber. of distribution.
- the collector depression measurement sensor is generally positioned in the engine compartment outside the engine; such an arrangement makes it necessary to provide suitable fixing systems and therefore also complicates the engine mounting operations.
- the object of the present invention is therefore to remedy these drawbacks by means of a suitable intake device comprising an intake manifold which groups together almost all of the tappings in a simple and economical manner. necessary for the operation of the engine and thanks to an air filter serving as support for the pressure sensor.
- the intake manifold is characterized in that the nozzles are carried by a single attached piece which is fixed to the body of the manifold in line with at least one corresponding opening opening into the distribution chamber.
- the nozzles are integral with the nozzle holder part.
- the nozzles are grouped together on the nozzle holder piece according to their function and to each group of nozzles corresponds an adapted opening arranged at through the collector body to open into the distribution chamber.
- the air filter is characterized in that it comprises a support adapted to receive the pressure sensor.
- the support incorporates clip means allowing easy mounting and dismounting of the pressure sensor.
- Figure 1 is a partial perspective view of the air intake device for internal combustion engine 1 according to the invention.
- FIG. 2 is a partial perspective view of the intake manifold for an internal combustion engine according to the invention.
- Figure 3 is a detail view of the nozzle holder plate shown in Figure 2;
- Figure 4 is a partial sectional view in cross section of the intake manifold to the right of one of the nozzles;
- Figure 5 is a view similar to that of Figure 4, showing an alternative embodiment of the taps.
- the air intake device shown is intended to equip an internal combustion engine with non-illustrated spark ignition of the in-line four-cylinder type equipping for example a motor vehicle.
- the intake device comprises an air filter 1 extending near an intake manifold referenced 2.
- This air filter 1 and this manifold 2 which are more particularly intended to be positioned side by side on the cover engine cylinder head, are connected to each other through a throttle body and connecting pipes not shown.
- the air filter 1 comprises a substantially cylindrical plastic housing made of two separate parts 10 and 11, both of which are molded.
- a first half-body 10 encloses a resonator cavity intended to reduce the intake noise while the second half-body 11 forms the housing for a filter cartridge not shown and has inlet 13 and outlet 12 holes for the oxidizing fresh air.
- the two half-bodies 10 and 11 are joined axially by a so-called quarter-turn fixing system; the second half-body 11 is immobilized on the cylinder head cover by means of a system of elastic straps provided with hooks, while the first easily removable half-body 10 allows, by its withdrawal, to freely access the housing of the filter cartridge.
- the various bearing surfaces of the second half-body 11 on the cylinder head cover are provided with elastic shock-absorbing pads, not shown, which come to interpose and operate a vibration decoupling.
- the half-body it also has, from molding, a support 6 extending projecting from the upper part of the half-body 11 and intended to receive a pressure sensor 3.
- This pressure sensor 3 has the function of measuring the absolute pressure prevailing in the distribution chamber of the intake manifold 2; the value of the manifold pressure used by the engine control system not shown to control the operation of the engine.
- the support 6 is more particularly designed to immobilize the sensor 3 in position by clipping.
- the support 6, adapted to the generally rectangular shape of the sensor 3, essentially comprises a bottom wall 18 on which the sensor 3 rests, as well as side walls 15 partially surrounding the wall 18 so as to form an open housing on the top at the interior of which the sensor 3 is positioned.
- the bottom wall 18 extends in overhang in the direction of the intake manifold 2 while being supported on three sides by ribs 16, it has a wide opening 19 opening onto the edge free facing the intake manifold 2 to allow the passage of the pressure tap 4 connecting the pressure sensor 3 to the intake manifold 2 and allow the installation of the sensor 3 already connected to the pipe 4 in the defined housing by support 6.
- the side walls 15 facing the two transverse ends of the sensor 3 are provided with lugs 17 able to come to press on the upper face of the sensor 3 and therefore immobilize the latter on the support 6.
- the assembly and disassembly of the sensor 3 are carried out simply thanks to the elasticity of the side walls of the support 6 resulting from the plastic material used to form the two half-bodies 10 and 11 of the air filter housing.
- thermoformed flexible pipe 4 acting as a pressure tap conventionally extends between the sensor 3 and a corresponding tap 5 carried by the intake manifold 2 which opens to the right of the latter's distribution chamber.
- Line 4 is however of a shape and length adapted to minimize the pressure waves prevailing in the manifold distribution chamber.
- the presence of a large number of elbows 14, five in the embodiment illustrated, provides the desired result for a reduced pipe length compared to the prior art.
- the present invention is also applicable for an internal combustion engine with compression ignition, in particular in cases where the air intake device comprises a compressor or an EGR flap and where the measurement of the pressure in the intake manifold is useful for engine operation.
- This manifold 2 made of plastic conventionally comprises a body molded having a distribution chamber or plenum 22 of substantially cylindrical shape, intended to extend parallel to the non-illustrated cylinder head of the engine, and four pipes 23 directed substantially perpendicular to the distribution chamber 22 and putting the latter in communication with the corresponding intake ducts formed in the cylinder head to supply combustion air or fuel mixture to each of the engine combustion chambers.
- tappings 5,8,7 which are respectively used for the measurement of the pressure and for the connection of the recycling pipes in the combustion air of the crankcase gases and fuel vapors coming from the canister as well as for the various vacuum connections, are according the invention grouped together on a single insert 24 extending parallel to the longitudinal axis of the distribution chamber 22.
- substances suitable for the combustion air substances non-combustible in the case of crankcase gases or combustible substances in the case of fuel vapors from the fuel tank and trapped by the canister
- the nozzles carried by the plate 24 are aligned along the median longitudinal axis of the latter and grouped in two distinct groups arranged at the two axial ends of the plate 4.
- the nozzles 8 corresponding to the introduction of non-combustible substances or secondary fuel while in the other end part 47 separated from the part 46 by an intermediate part of predetermined length 45, are arranged the nozzles 7 corresponding to the different vacuum connections of the engine as well as nozzles 5 used for measuring the vacuum.
- This arrangement of the tappings in two separate groups has the function of distancing the tappings 8 used for adding substances to the combustion air from the tappings 7 and 5 used for the depressions, so as to prevent any rise of these substances through the vacuum ports.
- Each group of respective nozzles corresponds to a single opening respectively 26, 27 opening into the distribution chamber 22.
- the opening 26 associated with the nozzles 8 is shown (the opening 27 associated with the nozzles 7 and 5 which extends in the extension of the opening 26 is perfectly similar to the latter except for the axial dimensions).
- This opening 26 is in the form of an oblong orifice 123 formed through the wall of the body of the intake manifold defining the distribution chamber 22.
- the oblong orifice 123 is surrounded by a wall 116 coming from molding with the body of the collector and extending projecting above the latter.
- the upper edge of this wall 116 forming a joint plane, has a peripheral groove 29 capable of receiving a complementary shouldered boss 64 extending under the part 46 of the plate around the different nozzles.
- the tap 8 incorporates an individual chamber 61 of substantially cylindrical shape having a flared entry opening extending in the extension of the orifice 123, this chamber 61 opens out by a suitable connection endpiece 60 of the type olive (or fir type) extending perpendicular to the axis of the chamber 61.
- the connection end piece 60 to which is connected the corresponding connecting pipe, not shown, is integral with the nozzle 8.
- connection end piece 9 is not directly integrated into the corresponding tap 406 but clipped onto the latter.
- the end piece 9 comprises an actual connection end piece 80 forming a body with a cap 84 which is fixed removably on the nozzle 406 constituted by a suitable tube 406 coming from molding with the wafer.
- the invention is not limited, in particular with regard to the nozzle holder 24, to the single rectangular shape and to the location on the distribution chamber 22 which have been illustrated in the figures, of even the invention is not limited to collectors only plastic intake but also applies to collectors from the foundry.
