Intake manifold with variable geometry vases. Intake system Intake system tuning elements

For optimal engine operation, the intake manifold of a car must have certain geometric parameters matched to a given crankshaft speed. For this reason, the classic design ensures correct filling of the cylinders only within a limited engine speed range. To ensure the flow of a sufficient amount of air into the combustion chamber at any speed, 16 valve engines VAZ 21127 and 21129 (Lada Vesta, Lada Iks Rey, Lada Priora, Lada Kalina 2, Lada Granta) use a system for changing the geometry of the intake manifold. Engine 21179 1.8 l. ., and all 8 valve modifications use a conventional plastic intake manifold without changing the length.

The intake system with a VAZ resonance chamber has an adjustable volume: controlled dampers reduce or increase its volume depending on the number of revolutions per minute. The volume of the chamber changes from larger to smaller, and the minimum volume value is used in the mode from 3500 rpm.

In one position of the baffle inside, air enters the inlet channels of the cylinder head from the first receiver through long channels. In the second position of the baffle, the second receiver is filled with air from the first, and from there the air enters the channel of the cylinder head.

The intake manifold of the VAZ 2106 itself is not difficult to remove, but before doing this, you first have to perform the following procedures:

• Pliers
• extension cords

Now there is little to do, with a certain effort it is necessary to pull the collector housing with your hands and remove it from the studs. This operation is clearly demonstrated below:

Self-replacement of the intake manifold on the VAZ 2107

To be honest, I have never had to deal with such cases in my practice when the VAZ 2107 intake manifold needed to be replaced. Since the part is made of aluminum alloy, it is actually very reliable and serves almost the entire life of the car. But this manual will help you if you are disassembling the engine, that is, the process of removing the manifold will be clearly shown. Below is a list of the required tools you will need to complete this repair:

1. Ratchet handle
2. Socket heads 13: regular and deep
3. Small to medium extension cord
4. Vorotok



Before proceeding with this procedure, you must first remove the carburetor. After you've dealt with this, you can move on.

The first step is to disconnect two hoses: the coolant supply and from the vacuum brake booster, this is clearly shown in the photo below:



Now you can unscrew the two nuts securing the intake manifold from above, schematically shown below in the photo:



The most convenient way to do this is with a ratchet and a medium extension:



Then we unscrew the three nuts from the bottom, which are visible in the picture below (the central one is not visible):



Also, using the ratchet handle, we do it quite quickly and conveniently:



After that, you can start removing the collector. Pulling it slightly to the side and remove it from the studs:



If it is necessary to replace this part with a VAZ 2107, we buy a new one at a price of about 1,500 rubles (500 rubles for a used one) and install it in the reverse order.

The intake manifold of a VAZ 2106 car can be replaced without assistance

Intake manifold device

To such an intake manifold, a photo of which is posted on our Internet portal, the pipes coming from the cooling system are connected. When diagnosing the operation of this component of the engine starting system, it is required to monitor the tightness of the joint of these parts with the fittings of the manifold system and the wear of the clamping clamps.

By its design, the intake manifold VAZ 2106, the price of which is not transcendental, but is in the permissible range, is a fairly reliable mechanical unit and rarely fails. Among the identified defects, it is necessary to note the incorrect installation of such a part as the intake manifold gasket, which occurs due to the incorrect installation of a spare part on a car either by a driver or by a car mechanic at a service station. Rarely, but still it happens that the intake manifold is corrosive and excessive air supply appears, which, of course, requires replacing it with a new product.

A standard manifold can be purchased at all specialized VAZ auto parts stores. Consider the intake manifold, the design of which is very simple. It consists of an inlet pipe, a drain pipe and a fitting through which the coolant is drained and cooled for normal vehicle operation.

Removal and replacement of the intake manifold

In case of damage, it is necessary to remove the VAZ 2106 intake manifold and replace it with a new product. For this purpose it is necessary:

5. De-energize the vehicle by removing the wire from the negative terminal of the battery.
6. Drain the antifreeze from the cooling system into a specially prepared container.
7. Dismantle the air purification filter on cars of the early years of production, and in modern vehicles - also disconnect the air supply hose from the filter.
8. Next, we carry out similar actions with the vacuum tube and the ventilation hose going to the crankcase from the air supply chamber. Having removed the fasteners, we dismantle this chamber with a hose.
9. Disconnect the fuel supply hose, while paying attention to the cessation of the flow of gasoline.
10. We remove the throttle cable fastening bracket, the sealing ring and disconnect the cable from the throttle valve lever.
11. We put marks on the antifreeze supply hoses from the body part of the air damper of the automatic principle of operation. We exclude leakage of antifreeze from the removed cooler pipes.
12. We put marks and disconnect the vacuum tubes from the front of the carburetor along with electrical wires and a career ventilation hose (if any).
13. We dismantle the fasteners and unscrew the vacuum hose of the brake booster vacuum from the intake manifold.
14. On some modifications, it is required to remove the installed wiring from the connector block coming from the temperature sensor.
15. We dismantle the fastening of the generator device from above to the intake manifold of the "six".
16. On some modifications, it is required to disconnect and dismantle the crankcase ventilation hose from the rear of the cylinder head.
17. Visually inspect the disconnection of all components of the vehicle systems from the intake manifold and dismantle it.

Installation of the intake manifold is carried out in the reverse order of removal of the product, taking into account the following features:

The necessary revision of the intake manifold is carried out for a more uniform flow of the gasoline-oxygen mixture through the cylinders of the power plant. The mixture of fuel and air "pulsates" in the cylinders due to incorrect dislocation of the carburetor flaps over the intake manifold of the "six". If some of the partitions on neighboring highways are removed, then the output is the elimination of constructive mistakes in standardizing the linear dimensions of the highways. In addition, a volumetric space is formed under the carburetor device, where the diffusion of the fuel-air mixture occurs before distribution along the highways.

Another way to modify the intake manifold is to fully coaxially align the carburetor windows, holes and cylinder head. Obstacles in the form of steps at the articulation points of the products create strong air currents that prevent the correct flow of fuel aerosol into the engine cylinders, and the vehicle loses its aerodynamic properties. It is required to remove these internal elevations and polish the internal planes of the cylinder head and intake manifold, which will make it possible to increase the torque value and the value of the vehicle's ultimate dynamics. At higher engine speeds, the result will be more noticeable.

This work is done to reduce the number of revolutions at which maximum torque is achieved and to increase power at high revs.

The most important thing is to mate the manifold (applies to both inlet and outlet) with the cylinder head. To do this, it is necessary to paint the mating plane of the head with a slow-drying paint (for example, Kuzbasslak) and lean the collector against it. Next, use a round file to select all light areas around the air ducts on the manifold. Then wash off the paint from the head and the manifold and repeat the procedure in reverse (paint the manifold, sharpen the head). You can limit yourself to one such cycle, but you can also repeat it again for accuracy. Accuracy can be checked by painting both the manifold and the head and clamping tracing paper between them. All inaccuracies can be seen from the print.

It is more difficult to deal with the gasket. You can't finish it with a file. You should use a drill or a round file clamped in a drill. The gasket is being finalized on site. Do not touch the metal inserts in the gasket around the exhaust ports.

Next is polishing. It makes sense to do it when the engine is overhauled. To do this, the valves, the axis of the rocker arms, the rocker arms themselves, and the camshaft are removed from the dismantled head. Then the collector is removed, the gasket is removed and they are screwed back on.

Now there are two options:

First, a 2 - 3 mm thick cable is taken and a layer of coarse abrasive paste (such as GOI) is applied to it and translational and rotational movements are made inside one of the channels (this is very long, hard and boring). Then, having visually checked the quality of rough processing, a tarpaulin is tightly wound on the cable and smeared with GOI paste. The procedure is repeated. This method does not guarantee maximum quality along the entire inner surface of the canal, but it guarantees that the most critical parts of the bulut are processed.

The second method, which I have not tested, but very promising, is a sandblasting machine. Here everything is the same as in the first method, but instead of a cable, a jet of compressed air with abrasive particles is used.

The standard VAZ 2106 intake manifold is designed to direct the air-gasoline mixture into the engine cylinders. Additionally, with the help of this important unit in the vehicle system, the fuel supply is heated, because when the combustible mixture is discharged, a reaction occurs with the release of cold.

The uniformity of the distribution of the air-fuel mixture over the cylinders largely depends on the intake manifold. Many believe that internal manifold polishing can reduce intake losses. But this operation itself is a torn page from a large book and can not fundamentally change anything. The uneven distribution of the mixture over the cylinders is primarily due to design errors in the design of the collectors. Different intake path lengths result in non-uniform cylinder filling, with the power balance across the cylinders varying depending on which carburetor throttle is open. Quite primitive (for the intake manifold of a rear-wheel drive VAZ) It looks like this: when throttling on the 1st chamber, as well as when the carburetor is idling - 1 and 4 cylinders operate on a richer mixture than 2 and 3. When throttling by 2 -th chamber (max load mode) a more enriched mixture enters 2 - 3 cylinders; and 1 and 4 are experiencing fuel "air hunger". The reason for this pulsation of the mixture through the cylinders is the unfortunate location of the carburetor flaps above the intake manifold. After removing part of the partitions between adjacent channels, we kill 2 birds with one stone:

1. Align the length of the channels.

2. A cavity appears under the carburetor, in which the mixture is mixed before entering the inlet channels, regardless of which chamber is throttled.

Also of great importance is the coincidence of the carburetor and intake manifold windows; intake manifold and head. The mixture moves in the channels at a high speed and the steps at the joints form powerful vortex flows that increase aerodynamic losses and prevent the mixture from entering the cylinders. Removing the steps at the junctions of the carburetor and intake manifold; the intake manifold and the head, as well as polishing the manifold and the inner cavities of the head to a mirror finish - we expand the range of torque and maximum power, and the higher the rpm, the more pronounced the result.

The step between the textolite gasket and the intake manifold, which is typical for most factory manifolds, creates additional resistance to flow in the intake tract.

Another way to optimize mixture formation on the standard manifold is to twist the air-fuel mixture in the large diffusers of the carburetor, and then continue this twisting in the intake manifold channels. Various primitive devices periodically enter the market, for example, homogenizers (in the jargon "turbines"), which are mounted under the carburetor and supposedly improve the mixture formation process. The mixture is indeed slightly twisted, but the homogenizer itself blocks the cross-section of the inlet channel and is a significant obstacle to the flow. So there is more harm from such a twist. Twisting the mixture without blocking, and in some cases even increasing the cross-section of the inlet channels, is technically much more difficult, but it is really feasible. This is our "secret weapon" and a topic for a separate conversation.

On sports cars, until the injection was firmly established on them, a different scheme was used - the installation of several carburetors. It gives a significant increase in torque and stretches it across the entire range - from low to max revs, as well as increases max power. But the general laws of working with collectors, outlined above, work here as well. And with the complex application of all methods, the results are brilliant.

The VAZ receiver is responsible for filling the cylinders. Its shape, volume, as well as the intersection of the intake pipes and the receiver greatly affect the behavior of the VAZ engine. The VAZ throttle controls the amount of air entering the intake tract. The intake manifold on which the VAZ carburetor is installed has a completely different design. In a VAZ injection engine, the air-fuel mixture passes along the shortest path in the channel to the VAZ valve seat, and in an engine with a VAZ carburetor, the air-fuel mixture passes through the entire manifold. This is the main reason for the difference between the intake manifolds. Standard receiver vaz is designed for maximum efficiency in the low and medium range of VAZ engine speeds, so its use in tuning will be somewhat inappropriate. The same applies to the VAZ throttle, its capacity may not be enough for a highly accelerated engine. And the standard carburetor vaz very often it becomes a spare part that does not allow the full potential of the engine to be revealed. VAZ receivers, which are installed for engine tuning, have a different design. They differ in the length of the channel, the volume of the receiver, the shape of the channel and the location throttle vaz... By the length of the channel, you can understand to what range of engine operation the receiver is tuned. With a long intake duct, the receiver is set for a low and medium range of engine operation, with a short one - for a higher rev range. The volume of the receiver must not be less than the volume of the engine. The location of the throttle and the volume of the receiver determines how even the distribution of air between the cylinders will be. In any case, whether you have a VAZ carburetor or a VAZ receiver installed, replacing them with tuning ones is required only with a deep revision of the VAZ engine. Today it has become very fashionable to install zero resistance filters on both injection and carburetor engines. Remember that filters require frequent cleaning. Otherwise, the timing valve may suffer from sand and

The standard VAZ 2106 intake manifold is designed to direct the air-gasoline mixture into the engine cylinders. Additionally, with the help of this important unit in the vehicle system, the fuel supply is heated, because when the combustible mixture is discharged, a reaction occurs with the release of cold.

Tuning

The uniformity of the distribution of the air-fuel mixture over the cylinders largely depends on the intake manifold. Many believe that internal manifold polishing can reduce intake losses. But this operation itself is a torn page from a large book and can not fundamentally change anything. The uneven distribution of the mixture over the cylinders is primarily due to design errors in the design of the collectors. Different intake path lengths result in non-uniform cylinder filling, with the power balance across the cylinders varying depending on which carburetor throttle is open. Quite primitive (for the intake manifold of a rear-wheel drive VAZ) It looks like this: when throttling on the 1st chamber, as well as when the carburetor is idling - 1 and 4 cylinders operate on a richer mixture than 2 and 3. When throttling by 2 -th chamber (max load mode) a more enriched mixture enters 2 - 3 cylinders; and 1 and 4 are experiencing fuel "air hunger". The reason for this pulsation of the mixture through the cylinders is the unfortunate location of the carburetor flaps above the intake manifold. After removing part of the partitions between adjacent channels, we kill 2 birds with one stone:

1. Align the length of the channels.

2. A cavity appears under the carburetor, in which the mixture is mixed before entering the inlet channels, regardless of which chamber is throttled.

Also of great importance is the coincidence of the carburetor and intake manifold windows; intake manifold and head. The mixture moves in the channels at a high speed and the steps at the joints form powerful vortex flows that increase aerodynamic losses and prevent the mixture from entering the cylinders. Removing the steps at the junctions of the carburetor and intake manifold; the intake manifold and the head, as well as polishing the manifold and the inner cavities of the head to a mirror finish - we expand the range of torque and maximum power, and the higher the rpm, the more pronounced the result.

The step between the textolite gasket and the intake manifold, which is typical for most factory manifolds, creates additional resistance to flow in the intake tract.

Another way to optimize mixture formation on the standard manifold is to twist the air-fuel mixture in the large diffusers of the carburetor, and then continue this twisting in the intake manifold channels. Various primitive devices periodically enter the market, for example, homogenizers (in the jargon "turbines"), which are mounted under the carburetor and supposedly improve the mixture formation process. The mixture is indeed slightly twisted, but the homogenizer itself blocks the cross-section of the inlet channel and is a significant obstacle to the flow. So there is more harm from such a twist. Twisting the mixture without blocking, and in some cases even increasing the cross-section of the inlet channels, is technically much more difficult, but it is really feasible. This is our "secret weapon" and a topic for a separate conversation.

On sports cars, until the injection was firmly established on them, a different scheme was used - the installation of several carburetors. It gives a significant increase in torque and stretches it across the entire range - from low to max revs, as well as increases max power. But the general laws of working with collectors, outlined above, work here as well. And with the complex application of all methods, the results are brilliant.

Replacing the gasket

The work is performed on a cold engine.

We drain the coolant.

We remove the carburetor.

Loosen the clamp and remove the coolant drain hose from the intake manifold, ...

… Remove the vacuum brake booster hose.

Using the "13" wrench, unscrew the four copper-plated nuts securing the intake pipe to the exhaust manifold.

With the key "13", unscrew the bolt securing the intake pipe to the gearbox and lower the intake pipe all the way (see Replacing parts of the exhaust system).

Turn off the nut with the "13" head ...

... and remove the negative wire and eyelet from the stud.

Having previously removed the hose from the warm air intake, turn off the bottom with the key "13" ...

... and the upper intake nuts.

We remove the air intake.

Remove the coolant drain hose from the heater radiator from the outlet pipe.

Using the "13" wrench, unscrew the second upper fastening nut ...

... and with a key "10" the bolt of the lower fastening of the heat shield of the starter, and remove it (see Replacing the starter).

Using the "10" wrench, unscrew the two nuts securing the pipe to the coolant pump ...

... and shoot it. A gasket is installed between the pipe and the pump.

Using the "13" head, unscrew the seven collector mounting nuts ...

... and remove the intake ...

... and exhaust manifolds.

We remove two gaskets from the studs.

We install the collectors in the reverse order, replacing the gaskets with new ones and lubricating the threads of the studs with graphite grease. We fasten the intake pipe of the muffler to the manifold with new brass nuts.

How to change

To carry out this repair, you will need the following tools:

Pliers
head 13, regular and deep
crank and ratchet handle
extension cords

After the air filter, its housing and the carburetor are removed from the car, you can proceed directly to the intake manifold. The first step is to remove the two hoses, which are shown in the picture below:

Now we unscrew the fastening of the air intake body, which is bolted to the manifold on the left side:

And take it out:

Now you can unscrew the nuts securing the collector to the cylinder head of the VAZ 2106. First, we unscrew the two upper ones, which are located at the edges:

The most convenient way to do this is with a ratchet with a head:

And then unscrew the three nuts securing the intake manifold from below. Two are visible in the photo, and the third is in the center, but it is not visible.

Here you need a long extension cord with a ratchet handle, otherwise you will have to suffer for a long time:

Now there is little to do, with a certain effort it is necessary to pull the collector housing with your hands and remove it from the studs. This operation is clearly demonstrated below:

Then we finally take it out of the studs and remove it from the engine compartment:

If necessary, we will replace this part. The price of a new collector for the VAZ 2106 and other Zhiguli models of the classic family is within 1,500 rubles.

Installation is carried out in reverse order.
