16 valve engine on the carburetor.

The heart of the car VAZ 2109 is its engine. The gearbox and clutch, together with the engine, create a power unit that forms a single unit and is fixed in the engine compartment.
16 valve engine VAZ 2109, compared to 8 valve, is distinguished by the best burden when they achieve large revolutions. This article discusses the question of how to remake the carburetor motor in a 16-valve engine on the VAZ 2109 to the injection engine.

Features of the injection motor on cars VAZ 2109

By car VAZ 2109 four-row, four-stroke, gasoline engine:

• The location of the cylinders in one row, in the engine compartment, the device is transversely.
• Sixteenth fuel has two distributive shaft. The cylinders work in this order: 1 - 3 - 4 - 2, the crankshaft pulley is counting.
• Phased distribution injection - the power supply system of the unit.
• Manages the engine controller.
• Most of the devices have a neutralizer of exhaust gases.
• On the engine on the right are located: camshaft drives, and generator.
• Left - thermostat, oil pressure sensors and coolant temperature, starter.
• Rear - oil filter, Collector graduation, crankshaft location sensor.
• In front intake manifold, with nozzles fuel ramp, detonation sensor, dipstick for oil level, generator, crankcase ventilation hose, phase sensor.
• From above, under the plastic lid, there are: a receiver, candles and high-voltage wires.
• The cylinder block is made of cast iron by casting.
• Cylinders are crushed in the block, have a nominal diameter of 82 millimeters. Repair dimensions can be increased by 0.4 mm or 0.8 mm.
  The cylinder class marking is made by Latin letters, below the block case. The maximum wear of the cylinder should not exceed 0.15 millimeters per diameter.
• The cylinder block with special bolts in the lower part is mounted, with removable lids, five bearings supports. The covers are not interchangeable, are specifically scattered on the outer surface.
  From the axial movement of the crankshaft protects the installation of the thrust half-trap in the nests on the middle support. From the side of the crankshaft pullee, a semiring of steel and aluminum is installed, behind the element is made of metal ceramics.
  One half hour or both change with an increase in the axial clearance of the crankshaft of more than 0.35 millimeters.
• Inserts of connecting rod and indigenous bearings are made by steel aluminum, thin-walled. On the fifth, the fourth, the second and first, the upper indigenous liners of the BC have on the inner surface of the groove.
  The grooves are missing on the lower indigenous liners, the top liner on the third support and connecting rod liners.
• On the car VAZ 2109 with a 16 crankshaft valve engine is made of high-strength cast iron, has five indigenous and four rod cervix. It has eight counterweights that are cast at the same time with shafts.
• Oil to connecting rod cervies is served from indigenous through, drilled in crankshaft shaft Channels that are closed with plugs.
• The crankshaft is mounted in front of the camshaft drive. It is connected to it, it serves as a damper for crankshaft oscillations.
• A flywheel with a steel gear crown is enshrined behind the crankshaft, which serves to start the engine starter.
• Pistons made of aluminum. In the longitudinal section, the cross section of the skirt of the conical shape, in the transverse section has an oval shape.
  On the outer surface at the top three grooves are made, for the installation of piston rings. For the lower oil-circuit ring in the groove, holes are performed, the oil from the walls of the cylinder is sent to the piston finger.
  On the bottom of the piston, the arrow is knocked out, which when installing the part should be directed towards the crankshaft pulley.

Tip: In the worn cylinder is not recommended, without its boring, install a new piston. It may turn out that in a new piston under the top ring, the flow will be slightly higher than in the same, which will lead to a breakdown of a "step" ring, which is formed at the top with the wear of the cylinder.

Two tops piston rings are compression.
They do not allow a breakthrough to the carcard of the engine of gases, and contribute to the removal of the heat piston to the cylinder:

• The head shared for four cylinders is installed. It is made of aluminum alloy. A gasket reinforced with metal elements is mounted between the head and block.

Tip: When repairing the engine, the gasket must be replaced.

All three details: block, gasket and head are fastened with screws.
The head is centered on the block with two sleeves:

• On both sides of the head at the top are five supports, for installation of camshafts.
• 16 The valve engine on the VAZ 2109 has two camshafts. Each of them are eight cams.
  In the cylinder, the pair of neighboring cams at the same time opens two valves. The camshafts are rotated from crankshaft with a toothed belt.
  Supported roller is under the pulley inlet camshaft, and tensioning - under the prom. On the toothed pulley of the intake camshaft, the disc is welded, providing the operation of the phase sensor.
  To assemble the node on the drive gears, there are installation labels: on the crankshaft pulley, it must coincide with the label existing on the oil pump housing, and labels on camshaft pulases with labels of camshaft drives located on its front lid.
• Metal-ceramic saddles and brass valve sleeve guides are pressed into the cylinder head. Inside the latter there are grooves for lubrication: for the entire length, they are made on the sleeves of inlet valves and up to 1/2 of the length of the opening on intake sleeves.
  From the contamination of the holes protect oil caps, parts made of oil resistant rubber.
• V-shaped in two rows are steel valves. The outlet valve has a head made from heat-resistant steel.
  They are powered by hydrotrifers from camshaft cams. The displacement of one millimeter of the cam axis relative to the axis of the hydrotherapler, allows the housing of the hydrotrode to turn around its axis.
  Due to this, it is evenly wearing. The operation of the hydrotherapists is performed with a constant supply under pressure of oil.
  It is provided by a channel located in Hz, which has a reverse ball valve that prevents, after stopping the engine, plums from the oil channels and channels supplying the oil to the cervical cakes located at the bottom of the bearing housing.

Tip: The hydrothels are very sensitive to the purity and quality of oil. Mechanical impurities can quickly disable them, which is accompanied by excessive noise and intensive wear of camshafts. A faulty hydrotherapler needs to be changed, it is not subject to repair.

• The valve closes under the action of one spring. She rests on the puck with the lower end, and on a plate that is held by two breadcrumbs is the top.
  Outside, folded crunches are made in the form of a truncated cone, inside - three stubborn boots, which are included in the valve rod, groove.
• On the car VAZ 2109 16 valve engine is equipped with a combined lubricant. Indigenous and connecting rod bearings, hydrotherapists, cervixes and layers of camshafts are lubricated under pressure.
  On the walls of the cylinders, then to the fingers and, camshafts camshafts, pushers, on the bottom of the pistons and valve rods, oil is splashing. Self lubricated the other engine nodes.
• Oil pump is installed on the front wall of the BC. Here are the internal engagement gears and a reducing valve. At the front end of the crankshaft installed the lead gear.
• In the Hz cover there is an oil separator for forced suction of gases.

How to redo the carburetor engine car VAZ 2109 in 16 valve injection

How to refit on the car with carburetor Engine VAZ 2109, with a 16th valve engine of injector type clearly visible on video. After carrying out all the work under the hood, there will be a completely different, pleasant view of the car VAZ 2109 engine.

Most of the "nine" owners know that you can install a 16-valve engine on VAZ 2109, thereby improving the running characteristics of its car on high revolutions crankshaft. Is it worth doing this, and how to realize the idea of \u200b\u200blife?

Why put a new power unit?

Installing a new engine can be useful to those motorists who want to improve their outdated car. Many domestic motorists know that the "nine" has pretty good running characteristics, it requires some gasoline and is generally not so good in caring, as foreign cars, so it is often tuning. Replacing the 8 CL engine on a more advanced model has its advantages:

1. Increase power.
2. Improvement sound characteristics At high speed.
3. Effective use of fuel due to the injection system.
4. More stable work power aggregate.
5. Not required permanent fit of valves.

But there are disadvantages:

1. To replace in your garage, you need a lot of details and tools.
2. On the low revolutions The engine at 16 cl down is a bit worse than its 8-valve analog.

Here are two replacement options:

1. Installing an integer engine from 2112 models. In this case, it will be necessary to replace not so much details, but the value of the whole engine can push away from this thought.
2. Refinement of the GBC for new components. This is a more economical, but very laborious process.

We put the finished engine

At the "nine" we put the engine 2112, since the power units of models are similar to each other. You will also need a fuel tube of a suitable diameter (you can take the steel, but better copper) and the gas tank from the same 12th model. Next, such works are held:

1. We dismantle the old power unit, turn off all the nozzles and electronics. In order to extract and put the engine, a tap is necessary for convenience, since the entire assembly node. This is the main problem in the garage.
2. When the engine is removed, you can install a new one planting place. It is worth it to immediately check the condition of the glands and pads, if the unit used. Check for still belt tension.
3. Next you need to replace all fuel system: Tank, gas station, fuel lines.
4. An excellent replacement for the "nine" tank is analogue from 2112. The details on the size coincide, but they have a different device that is not an obstacle to installation.
5. For fuel highways need to be taken copper tubeswho are better than bend.
6. Now you can enjoy the wiring of the injector. If the "nine" of release is 2002 and younger, then there will be no special problems with connecting wires, and for old models you will have to do new holes manually.
7. You need to install absorber and gasoline filter. Usually they are placed under the bottom and fasten with studs.
8. We put the sensors, change the wiring to the one that is suitable in length.
9. With the installation of the generator will have to sweat, since native attachments are not suitable. Look suitable, replace - you can install. If the gearbox is not changed, then it will have to be tolded with a grinder.
10. At the starter will have to change the Bendix from 12 to 9 teeth.
11. Last alteration - exhaust system. Pipes will not suit, so they will need to digest. Fit helps all the details put in place.

The motor capacity of such a car as a VAZ 2114 may seem insufficient for very many motorists. However, this can be corrected. We are thinking how to remake 8 valve engine on 16 valve in VAZ 2114

If you install the head for the cylinder block with 16 valves, then the power of the car can exceed all expectations. The reason for this is that the motor cylinders with a similar block of block can be filled with a special fuel and air mixture.

As a result, the power of the force aggregate increases significantly. It is important to note that it is absolutely safe method In order to increase the "power" of your car. So how to remake 8 valve engine on 16 valve VAZ 2114?

There is a question about the difference in car power. For example, the power of the machine whose engine reaches the volume of 1.5 l, and the number horse power Equals 77, you can significantly improve. If you replace the 8th valve head on a 16-valve, it will increase to 90 "horses"!

This is quite a big difference, so you should figure out what needs to be done (and in what order) to improve your own car.

Features of engine disassembly

The first thing to do is how it can be careful to disassemble the engine. This element of the car is the most valuable, so the motor must be disassembled extremely carefully. It is best to carefully examine the instructions and see the video on the Internet about how the masters are coping with this task, and after that, to disassemble yourself.

Under the valve lid, you can detect a lot of unpleasant defects, including the poor condition of the roller. The cylinder head can also look in the best way, and the bushings are so worn out that many are surprised that they still work.

All this means that after the engine is disassembled, you can detect a lot of faults or worn items. It is best to replace each of them. It will increase the reliability of the car and will not allow not worrying that the increased power of the vase can become a fatal factor and lead to breakage already in the near future.

It is best to install bronze bushings. They possess high reliability And rather durable.

Installation 16 valve head on VAZ 2114

In order to accomplish this simple operation, the engine should be disassembled. It is worth warning that many details will have to be replaced.

These include:

• tosol tube;
• oil pump;
• oil Carter;
• various sensors;
• crankshaft and much more.

Despite the impressive list, the method described below in the text really helps make the car even more powerful than before.

Alteration of the engine VAZ 2114

Alteration 8 valve engine in 16 valve VAZ 2114

During the process to improve the engine, you need to modify bolts. They are used to secure the 16-valve head. To upgrade the VAZ motor, there is no need to change the cylinder block, but the head will be changed anyway. In order for each bolt to reliably enter the head of the head fastening, it should be adjusted not only in diameter, but also in length.

Important information. Holes that can be found in the laying also need to be improved. They must be perfect for the size of the bolts. If this is not done, the level of engine reliability will significantly decrease.

After that, it should be changed:

• • peshni coupling;

• and then rods.

Rolling rods VAZ 2114.

It is necessary to do this during the assembly of cylinders.

Now the cerebrals of refinement and fitting wiring came.

It is important to see the difference in the structure of 16 valve pistons from 8 valve. In addition, the location of the sensors also differ. This means that it may be necessary to lengthen the wiring.

After the engine is assembled, you need to finalize the wiring. If the car owner would not want to receive extra financial expenses, then he needs to leave the ignition module, then connect the module using high voltage wires. This is the easiest way to save, so it is not worth ignoring it.

How to remake 8 valve engine on 16 valve installation features

Bolts visually can be very different from each other, but it is not necessary to scare. You need to use modified bolts.

Such bolts have the following characteristics:

1. The diameter is equal to the 8-valve bolt;
2. The length is equal to the 16-valve.

In order to facilitate the passage of these bolts into the hole, they should be drilled in advance. If you set the modified bolts over all the rules and as carefully as possible, the engine reliability can only be envied.

GBC VAZ 2114 bolts

When the auto owner seems to be that it is not able to fulfill this operation independently, it is better for help to help qualified craftsmen with sufficient experience. They will definitely do everything right and the way.

An additional option to increase the power of the car lies in the tuniting of the exhaust manifold. This is a great way to further increase the capacity of its motor vehicles.
