Characteristics and malfunctions of the VAZ 2110 16 valve engine

VAZ-2110 engines with a two-shaft head with 16 valves are built on the basis of the old one and a half liter VAZ 21083 engine. Changes affected only the cylinder head and air supply system. Twin-shaft 16-valve engines were installed in two types - a 1.5-liter engine (VAZ-2112) and a 1.6-liter engine (VAZ-21124). The ignition system on these engines is different. Today we will look at the ignition module for the injection 16-valve engine 2112 and find out its differences from the 1.6-liter engine 21124.

Technical specifications

The VAZ 2110 engine has high performance. At the same time, several variants of power units from AvtoVAZ were installed on the vehicle during the production process. The “Ten” had in its arsenal several variants of a sixteen-valve engine.

Let's look at the main technical characteristics of the VAZ engines with which the 16-valve model 2110 was equipped:

VAZ 21120

Not a very popular version of the power unit. Although the engine power is high, as practice has shown, this engine did not take root on the VAZ 2110, since it had a number of design flaws. Basically, the engine was installed on a car marked VAZ 21103.

VAZ 21124

A sixteen-valve version of the power unit, which received almost 100 horsepower and had high technical characteristics.

The average lifespan of a Lada engine is 250,000 km. If you use high-quality oil in the VAZ 2110 engine, you can increase the service life of the power unit by 20-30 thousand km.

Symptoms of module malfunction

Signs of a faulty ignition module on a VAZ-2110 are always acutely felt:

• hesitant engine starting or failure to start;
• failures during sudden changes in speed;
• high fuel consumption;
• two cylinders do not work, the engine is feverish;
• lack of dynamics;
• a sharp drop in power;
• drop in power and thrust after warming up.

Other faults

We unscrew and look at the spark plugs.

Checking the high voltage wires.

These symptoms may not only be caused by the ignition module. To determine the malfunction, it is enough to spend a few minutes diagnosing spark plugs, high-voltage wires and caps. This will eliminate the remaining elements of the ignition system and make sure that it is the ignition module that is faulty.

1. Checking the spark plugs . To do this, unscrew them, put on the caps, place them on the cylinder head and crank the engine with the starter. The spark should be stable on all spark plugs. We replace non-working spark plugs and repeat the test. Under no circumstances should you crank the engine with the starter with the high-voltage wires removed. This will lead to a breakdown in the ignition module cover.
2. Checking the high voltage wires . We remove the caps and hold the wire contact through the insulator at a distance of 10-15 mm from the head . With good wires, the spark should pierce this distance vigorously and confidently. Next we check the wires for resistance. A working wire should have a nominal resistance of 7-10 kOhm. Any deviation from this value indicates the need to replace the entire set of high-voltage wires.
3. Checking the caps for breakdown.

   We also look at the block and especially the wires included in it.

If all these elements are in good condition, the ignition module must be checked.

In addition, it is better to check the spark plugs and wires on a warm engine, since a half-dead ignition module can operate cold for some time and fail when heated. You also need to be sure that all sensors are working properly. This can be indicated by an error code or Check Engine light.

Algorithm for checking the ignition module on a VAZ-2110

We begin the test with the block connected to the module.

To check the module, we only need a multimeter and it will take 15-20 . This is quite simple to do, the main thing is to adhere to the algorithm and know the nominal values ​​of the working module:

1. We check the power supply and the presence of pulses supplied from the ECU . We check the power between the central terminal (15) of the wire block connected to the module and the engine ground. When the ignition is on, the voltage should not be less than 12 V. Otherwise, either the battery is dead or the ECU does not work.
2. We check the pulses from the ECU on the wiring block . We install one tester probe on connector 15, the second on the far right, then on the far left. The assistant cranks the engine with the starter, and at this time we record short-term voltage surges with a tester. If there are no impulses from the ECU, it is he who is to blame.
3. We check the resistance on the secondary windings of the coils . We put the tester in resistance measurement mode and measure it at the high-voltage terminals of the module cover. Between pins 1 and 4 and pins 2-3, the resistance should be 5.4 kOhm. Otherwise, the module must be replaced.
4. We check the resistance of the primary windings between contacts 15 and the rightmost, then the leftmost terminals. Nominal - 0.5 Ohm . Deviation is not allowed.
5. Check the module for a short circuit . In ohmmeter mode, install one multimeter probe on the central terminal, the second on the metal body. There shouldn't be any resistance. If the device detects at least some resistance (other than unity or infinity), the module must be replaced.

Service

VAZ 2110 engines are serviced quite typically. Thus, scheduled maintenance is carried out within 10-15 thousand km. If the vehicle is operated on LPG, then maintenance must be reduced to 8-10 thousand km in order to preserve the engine and extend its service life.

When servicing, it is necessary to pour only high-quality oils into the VAZ 2110 engine. Thus, there are a number of lubricating fluids that must be poured into the engine. Do not forget about using a high-quality oil filter, which will also affect the service life. The power unit maintenance scheme is quite simple, and is provided by AvtoVAZ in the repair manuals.

The VAZ 2110 engine with 16 valves is quite unpretentious in the use of oil. So, both semi-synthetic and synthetic lubricant are ideal for him. Many car enthusiasts ask the question: how much oil should be poured into the engine? Almost all engines require 3.5 liters of oil.

Overhaul of VAZ 2111 engine

Overhauling an engine is a rather labor-intensive process; in this article we will consider the entire process of such repairs using the example of a 1.5 liter VAZ-21113 16V engine from 2000, after traveling 95 thousand km. During the repair, the following parts were removed and replaced:

First of all, we get rid of antifreeze and oil.

When unscrewing the cover, remove the receiver mount.

We get rid of the throttle cable and connectors from the diesel engine, remove the ground wires.

It's worth removing the receiver.

In front of you is a receiver, explosive wires and spark plugs.

Armed with a 10mm wrench, unscrew the bolts that secure the timing belt cover.

We remove the ground wires, and then the gas pipe mounting bracket.

We place the front wheel on the jack, after aligning the marks, remove the bolts securing the gears, as well as the roller nuts.

After this, we remove the gears, the main thing is to protect them from losing the key, and remove the rollers and cover. First, you may have to remove the pulley located on the crankshaft.

Before removing the fastening bolts, you should hit the threads a little with a hammer, this should be done through a wrench.

Then unscrew the fastening bolts holding the ramp and hexagon.

After removing the bolt, remove the dipstick along with the trunk.

We take out the ramp, as well as the injectors, move it to the right, and pull it towards us.

We put it aside; do not unscrew the hoses.

Remove the head cover.

Perhaps the bracket will get in the way, you should remove it.

To remove the middle head, unscrew the fastening bolts; there are cases of removing the camshaft along with the head, like mine.

We remove the camshafts and spark plug wells.

Malfunctions

A major overhaul of a VAZ 2110 engine means restoring the engine and its components to factory standards. This operation is carried out when the motor has passed its service life and there is exhaustion in the main components.

Due to the fact that the engines have been in use for a long time, some engines are 10-15 years old, a major overhaul is inevitable. So, the combustion chambers have already worn out, and the pistons have burned out from service life and mileage. In addition, engine oil for the VAZ 2110 no longer helps to maintain performance to such an extent.

So, it is worth repairing the power unit at a car service center, especially with regard to the 16-valve engine. The VAZ 2110 8-valve engine is used by most motorists in garage conditions, since it has a simple design that is similar to the Classic and Samara power units.

Detailed instructions for disassembling and repairing the VAZ 2110 engine:

2. Remove the clutch from the engine.

3. Remove the tension roller, camshaft drive belt and spacer washer, which is installed under the tension roller.

4. Remove the toothed pulley from the camshaft.

5. We unscrew four bolts, three of which attach the water pump. Unscrew the fastening nut on the rear cover of the camshaft drive belt and remove the cover.

6. To remove the water pump, insert a screwdriver between the block and the flange of the pump housing and thus move it from its seat. After completing these operations, remove the water pump.

7. Remove the head from the cylinder block.

8. Unscrew the bolts (there are 16 of them) securing the oil sump, then remove it together with the gasket.

9. Unscrew the bolts (there are 3 of them) securing the oil receiver and remove it. Please note that there are spring washers under the bolt heads.

ECU diagnostics

In modern times, many methods have become available for conducting self-diagnosis or diagnosing a power plant malfunction with your own hands. Without any problems, you can purchase various diagnostic equipment, and you don’t have to go to a car service center. So, you can connect to the ECU using a standard OBD II cable and a tablet, or purchase an ELM 327.

Also, some errors can be diagnosed using the instrument cluster. First you need to enable test mode:

1. The ignition is turned off. Battery included.
2. Press the “Reset” control button and, holding it pressed, turn on the ignition. All positions of the familiar areas (segments) should light up on the LCD – LCD control.
3. Press any of the control buttons. The LCD should display the program version (Ver 1.0).
4. Press any of the control buttons. The following error codes (if any) should be displayed on the positions of the first and second lines of the LCD.
5. Press the “Reset” control button and hold it for no more than 3 seconds. (maybe a typo, I need more than 3c). Error codes should clear to zero.
6. Press any of the control buttons. All positions of symbols (segments) should light up on the LCD – LCD control.

Error codes: 2-overvoltage of on-board network;

3-fuel level sensor error (if a break in the sensor circuit is detected within 20s);

4-error of the coolant temperature sensor (if an open circuit of the sensor is detected within 20s);

5-outside temperature sensor error (if there are no sensor readings within 20s, indication on the LCD is “-C”);

6-engine overheating (the criterion for triggering the acoustic alarm is met);

7-emergency oil pressure (the criterion for triggering the acoustic alarm is met);

8-defect of the brake system (the criterion for triggering the acoustic alarm is met);

The 9-battery is discharged (the criterion for triggering the acoustic alarm has been met);

E-determination of an error in a data packet stored in EEPROM.
