Camshaft 2112 inlet. Tuning and sports camshafts

27.09.2019

Each of us is trying to improve your car in every way, and the way to this is a great set. When it comes to the engine, all in one voice says about increasing its power. Although, if you more seriously approach the question, then you must pay attention to its torque.

We know that it is possible to squeeze the largest power with stable maximum turnover, but such an engine mode is rarely applied. An ordinary driver is more important than the rigging of the car, which obediently responds to the gas pedal both in the course mode from the place and when it is accelerated. Such behavior of the machine is provided by a large and relatively constant torque on low and medium-sized turns than and "sin" VAZ engines. At the low speed of rotation of the crankshaft, they do not have enough "thrust".

The owners of the VAZ car often complain about the jerk of the car at the beginning of the movement, noticeable failures at harsh pressed On "Gas", many quickly "flies" the clutch and practically everyone notes the inefficiency of the fifth transmission. Indeed, when engine revolutions less than 3000 rpm. It has its insufficient taughtness. The torque curve depends on the parameters of the gas distribution, the so-called "phases of the camshaft", as well as the "time-section" of the opening of the valves, which are specified by the camshaft camshaft profile. Depending on its corner of turning and the valve opening is obtained. For better operation of the car on low revolutions It is achieved to feed the desired volume of the working mixture into the cylinder, that is, they are noticeably narrowed by the opening phase of the inlet valve.

Unlike ordinary camshafts, in sports models Fittings with other geometric sizes are used. Their higher and wide form leads to the fact that the valve rises to a large height and is in the open state longer, which ensures the supply of a full mixture. The cam profile is characterized by the smoothness of the forms, which makes the operation of the gas distribution mechanism more reliable on the wide phases.

From the foregoing it follows that the maximum engine power and its torque can have different values. And if the use of a standard camshaft involves an increased torque on medium-sized circulation, the sport ensures maximum return on high revolutions Engine. Sports camshaft on VAZ cars is installed with a split gear (), with which more accurate adjustment and phase adjustment becomes possible. With it, the highest power is adjusted on the necessary engine speed.

The use of tuning camshafts can be achieved by the engine under load without noticeable interruptions, even when the revolutions decreased to the limit level. At the same time, the border of detonation is moved, that is, they cease to "knock the fingers" on the small and medium turns of the crankshaft. Noticeably reduced fuel consumption and reducing toxicity exhaust gases. As a result, the engine's tendency to detonation decreases, which means its resource increases.

Camshafts on VAZ engines It is quite sensitive to adjusting the gaps, so the tuning camshafts have noticeably increased the plot of outbabing cams on the closing side of the valve. This makes it easier to adjust the gaps and reduces them several times. Make this fact on the following example: after installing the tuning camshaft, the adjustment of valve gaps is required after 60,000 km of engine run. When using the usual camshaft, no less than four adjustments would need. This significantly increases the life of the product and saves the means and the time necessary for each valve adjustment. Calculate yourself: competent adjustment takes at least 3.5 hours and costs about 20 USD.

Classification of camshafts

You can divide into two groups: lower and riding. By name it can be seen that some increase the moment on low engine speeds, while others on high speed. This is achieved by changing the height of the lifting and a special profile of cams, as well as certain phases of opening / closing valves.

Low camshafts

This type of product has a small height of the rise in the absence of valve overlapping zone. Such a regime prevents the working mixture to be discarded on low revs back into the inlet. Of course, the small height of the lifting causes the loss of filling in high speed and it leads to a decrease in the maximum engine power. Therefore, mainly they are used when driving around the city.Do not forget that the engine power, mostly affects only maximum speed your car that is not critical indicator. For example, you can bring the following numbers: reducing the power of the VAZ-2109 engine per 10 hp It will reduce the maximum speed of only 6 km / h.

The advantages of the lower shafts include an increase in torque on "Nizakh". This will allow you to sharply accelerate from the traffic light, not including reduced transmission. On medium turnover, these camshafts are no better than serial, but on high even worse.

High camshafts

These products, on the contrary, have high lifting, a large zone of overlapping valves and wide phases. Such a regime increases the filling on the "vertices", which is due to an increase in the flow section in the zones of the valves and through the use of the effect of inertial supervision. This leads to an increase in engine power, and the maximum torque is shifted to the high revolutions zone. Unfortunately, the failure is noticeable on the "Nizakh", which is due to the wider phase, during which the working mixture is pushed back into intake manifold at low speeds. And what best features It has horseraded camshaft, the stronger this effect.

Tuning and sports camshafts

The riding camshafts are additionally divided into tuning and sports. Their difference, mainly relates to phase characteristics, lifting valves and overlap heights. The greater the height of the lifting, the higher the moment and, as a rule, power at high speed.

Practically unsuitable for use in urban driving conditions. They have a noticeable failure at low revs and rather unstable increased revs idle move. The maximum return on them occurs only in the region of almost limit frequencies of the engine rotation, which is unacceptable under normal driving conditions.

One of bright representatives sports class products can be called

Replacing the camshaft on the 16-valve VAZ-2112 motor occurs when they are wear and use and the production of support necks. Most often it happens when time passes overhaul Power block or CHC. This is a rather complicated procedure, but it really makes it yourself.

On the video below the installation of camshafts and split gears on 16 valve engine VAZ family

Video material will tell how to replace switchgear on VAZ-2112 16 valves will give some recommendations and tips.

The process of replacing camshafts

Distributional shafts with gears and fasteners

In order to install camshafts on VAZ-2112 16 valves, they must first dismantle. Like any spare part, they are installed in the reverse order of disassembly.

So consider phased process Removing and installing intake and graduation distribution Vala.

Installation of distributional shafts

Now that everything is removed, you can change the installation of new camshafts on the car:

Choice

The switchgear shafts of the cylinder block for the VAZ-2112 are made only by the manufacturer only, therefore the analogues are not necessary.

Original catalog numbers: intake - 2112-1006015, graduation - 2112-1006014. Each camshaft is on average about 3000 rubles.

Marking inlet camshaft labeling of the graduation camshaft

Nuances

When installing the bearing housing and block head, it is impossible to apply a sealant that contains silicone. This is due to the fact that the motor is heated, and accordingly the sealant, which highlights the pairs, which can get into cylinders and then on the system. It is worth using a sealant that in the instructions or on the package it is indicated that it is safe for the oxygen sensor.

When applied to the sealant on the cavity, it is not worth a lot to apply it, because when tightening the bolts, it can get inside and this will lead to the clogging of oil channels, and there will be no lubricant accordingly. Absence lubricant will lead to elevated wear of parts that will quickly fail.

conclusions

Replacing and installing camshafts on the 16-valve VAZ-2112 is not entirely easily, but quite real. The main thing is to ensure the result, it is caution and execution of instructions. It is worth noting separately that the intake and exhaust camshaft are different, and not interchangeable. There is an additional katch under the phase sensor.

Replacing camshafts on VAZ 2114 do it yourself

Distributional shafts, like other mechanisms and nodes of the car, determine the quality of the engine. This material will prompt you how to determine the malfunction of the shafts, how to replace the camshafts on the VAZ 2112 16 valves, and that it is necessary to prepare.

The pulleys of the 16-valve VAZ 2112 must be replaced when they wear out or there are mechanical damage. In particular, we are talking about:

failure or a spent resource of the operation of the support neck of the pulley;
mechanical bending of the camshaft;
exhaust service resource, as well as element cams.

If during the operation of the engine in the valves there is some other stupnery, then it is usually caused by one of such damage. In the event that you recorded a reduced pressure motor fluid In the system, this may indicate an increase in gaps in bearings.

To do this, in order to eliminate this malfunction, it is necessary to inchlip and restore the support cervix. You should also increase the grooves, with which the engine fluid flows. This is done so that the lubricating fluid after the next column produced lubrication of the elements of the DVS. As for the neck, they should be polished by green paste gay after grinding.

Stages of work

To properly implement the process of replacing the graduation elements, we suggest you to use the instructions prepared specifically for our users. Also, this manual is suitable for those who want to replace the seals of the graduation camshaft, sensors or plugs.

Open the hood of your 16 valve vases 2112. Remove the protective casing of the gas distribution mechanism strap.
After that, it is necessary to remove the cover of the GBC, as well as the device for controlling the emergency pressure (sensor) of the engine fluid. The sensor is removed so that it is not damaged during the work. You can also remove the tip of the sensor wires.
When the sensor is dismantled, you need to unscrew all the screws that fasten the housing of the camshaft bearings. This is done with the facest of the "8". All bolts should be unscrewed evenly, not one.
After that, dismantle the casing of the grade valve flap of the valve VALA 2112. It should be noted that the housing is dismantled with the candlestones. They need to be pulled out of the housing.
Now it concerns the plugs of the technological holes. During the procedure for replacing the camshafts, the plugs are often lost in motorists. Caps are small parts of a round shape.
The plugs need to be dismantled from the installation locations in the GBC, a total of a plug - two, and they are located in the area of \u200b\u200bthe rear ends of the camshafts.

When these elements are dismantled, put them separately. The plugs are better not to lose.
After that, it is possible to disassemble the camshaft of the exhaust valve. The camshaft of the exhaust valves is desirable to shoot first. When the graduate valve camshaft is removed, proceed to dismantling the element of the inlet valves.
Now the case is left behind the glands. We proceed to the dismantling of the glands, lay them aside. By the way, when dismantling the glands also be careful not to damage them. After removing the seals, make an inspection of dismantled devices. On the glands should not be mechanical damage, traces of wear, microcracks, etc.
If you decide to install sports camshafts on your 16 valve VAZ 2112, then you need to purchase tuned items in advance. Installation of sports elements is distributed among Russian motorists. Take your sports camshafts and lubricate their cams, as well as the reference elements of the engine fluid.
Consider: graduation and intake sports components are not interchangeable, marked with marking. For example, figures 1006014 are applied on the components of the exhaust valves.
After that, around the perimeter of the GBC 16 valve VAZ 2112, as well as on the surface of the housing of the pulley bearings, you need to apply a small layer of sealant. More accurate place of application are marked in the photo. With a sealant, it is better not to overdo it.
When the sealant is applied, the pulleys can be put in place of installation.
Then make the installation of the housing of the bearings on the GBC. Tighten all the screws evenly until the parts of the items will not be faced with the GBC. By the way, the screws are also desirable to tighten in a certain sequence, you can learn more about it on video and photos.
Then the glands should be pressed, as well as mount the plugs in the GBC 16 valve VAZ 2112. After that, the assembly must be made in the reverse order, do not forget about the sensor.

How to distinguish inlet camshaft from graduation VAZ-2112: photo

The distributional shafts of the 16-valve VAZ-2112 introduce the working mixture, and produce exhaust gases. In contrast to the 8-valve motor, where one camshaft serves for inlet and release, on the 16 valve - for each phase it is its element. This improves not only the characteristics of the engine, but also contributes to a smaller consumption. fuel mixes.

Differences of camshafts

The difference between the intake and exhaust camshaft in the presence of a groove under the phase sensor

In fact, the difference in the design of the graduation and intake camshaft is not. There is only one reason why they are not interchangeable. On inlet distributional There is a katch, which is calculated under the gas distribution phase sensor.

Some car enthusiasts instead of standard factory camshafts set sports that increase power. It is in this case that the essential difference begins.

The inlet camshaft has a larger cam size, which in turn opens the valve not by 7.6 mm, and by 13.2. This allows the engine to increase the power characteristics. So itself and graduation has some other characteristics - the valve is open at 7.6, and by 10.8 mm, which significantly adds power.

Sports camshaft differences

conclusions

Distributive shafts of the 16-valve engine on VAZ-2112 are no different constructive features, Besides the fact that an additional edge under the camshaft sensor (phases) is flowing on the intake shaft. If the intake and graduation element is confused by places - this will lead to a violation of the phases of gas distribution and if the engine will work for a long time in this mode, the owner inevitably waits for overhaul of the block head, at best.

Proper tightening bed of camshafts, as well as the remaining parts of the cylinder head, determines the normal functioning of all nodes and units. So, in order to tighten the threaded connections used typical scheme Tightening and dynamometer key.

Before installing bolts in place, rinse them well and lubricate silicone lubricant

In order to properly tighten the bolts, you need to know the sequence. It begins with the middle part and stages goes directly to the edges. The detailed sequence can be seen in the photo below.

Drawing diagram of each bolt camshaft bed with numbering

As for the directness of the tightening force, it is 8.0-10.0 nm. After the bed is installed on the block head, the compound bolts are twisted with their hands or without a special force with a ratchet with the head.

Twist all bolts from hand, but do not delay

When all the bolts have become in place, you need to take a dynamometric key and tighten according to the standards in the order specified above.

Video from Artem Yershova "Replacement of pulleys for VAZ 2114"

In this video you can look at the process of replacing the pulleys in the 16-valve car VAZ.

Dear buyers, in order to avoid errors when sending camshafts, in the "Comment" line, specify the model of your car, year of release,number of valves.

For VAZ valve drive 2112, 2170, 2190, 21126 (16V. ) Two camshafts are used - intake and graduation. The shafts are cast from cast iron and have five supporting necks that rotate in the slots performed in the cylinder head and in one general body of the camshaft bearings. To increase the wear resistance, the working surfaces of the cams and the surface under the gland is bleached.

To distinguish the inlet camshaft from the graduation on the intake shaft near the first support, a distinctive belt of A.

1 - block head; 2 - inlet camshaft;3 gland; 4 - exhaust camshaft; 5 - camshaft bearings housing; 6, 8 - sealing rings; 7 - guide tube; 9 - block head cover; 10 - bracket fastening of the wiring harness; 11 - plugs; A - distinctive lines of the intake camshaft.

From axial movements, trees are held by stubborn colors located on both sides of the front support. The front ends of the camshafts are compacted by self-sufficient rubber glands. The rear holes located along the axis of the shafts in the head of the cylinder block and the housing of the bearings are closed with rubberized cap plugs.

Switchgears are driven by pulley 1. on the crankshaft shaft using belt with gear strap. To drive two camshafts with a non-free gas distribution mechanism, an enlarged torque is required. Therefore, the belt width is increased to 25.4 mm (instead of 19 mm in engines 2110). Accordingly, width increased pulley and rollers.

1 - gear pulley of the crankshaft; 2 - toothed belt; 3 - pulley of the coolant pump; four - tension roller; 5 - pulley of the exhaust camshaft; 6 - rear protective cover of the toothed belt; 7 - pulley of the inlet camshaft; 8 - Ring for the phase sensor; 9 - supporting roller;

A - NMT label on the crankshaft pulley; In - installation label on the oil pump lid; C and F - installation labels on the rear protective cover of the toothed belt; D - installation label on the pulley of the exhaust camshaft; E - installation label on the intake camshaft pulley

Under the pulleys of the camshafts are located two rollers: On the left - tension 4, and on the right - the support 9. At the support roller, the mounting hole was made in the center of the inner cable, and the stretch roller is located eccentric (shifted from the center by 6 mm). Therefore, turning the tension roller relative to the stiletto, you can adjust the belt tension.

The pulleys of the camshafts are distinguished by the fact that the pulley has 7 inlet camshaft welded disk 8 for the operation of the phase sensor. Belt drive front and rear is closed with plastic covers.

To set the phases of gas distribution, installation marks A, D, E on the pulleys and tags B, C, F on the lid oil pump and the rear cap of the camshaft drive. With properly installed phases, the label A should coincide with the label in, and the labels D and E - with the marks with and F.

When assembling the engine, you must always install a new gasket under the head head. The use of the former gasket is not allowed.

Before installing the gasket, it is necessary to remove the oil from the mating surfaces of the block and its head. The gasket must be clean and dry. Outputs on the surface of the gasket is not allowed.

The cylinder head fastening bolts are allowed to be reused only if they stretched to long L not more than 95 mm. If the length of the bolt is more, then replace it with a new one.

Before assembling the engine, burn the threads and heads of the bolts in advance, dipping them in motor oil. Then let's drag over the oil, withstanding the bolts for at least 30 minutes.

Remove the oil or cooling fluid from the holes in the cylinder block under the block mounting bolts.

When installing, harsh gentle belt gear is not allowed with a radius of less than 20 mm so as not to damage the cord.
