Setting the ignition timing for any vehicle is a very important parameter, ignoring which will cause some systems to malfunction. How to perform this operation? All this and more - further in our article.

Reason for adjustment

For example, if the ignition is set incorrectly, it will be difficult to start the engine, fuel consumption will also increase and there will be a loss of power. In other cases, incorrectly installed ignition led to engine overheating or detonation.

Therefore, adjustment is one of the components of the current car repair. Currently, there are many ways to install the ignition on cars. Ignition for cars is set both with the help of a stroboscope and without it.

Working order using the stroboscope

To make adjustments with a stroboscope, you need to prepare a stroboscope, car tool kit, dielectric gloves.

The event for setting the ignition should be carried out onopen space, without visible interference in the form of sunlight. The stroboscope must be in good condition, without mechanical damage, as during work you can get an electric shock.

Stages of work

Setting the ignition timing with a strobe is quite simple. Need:

1. Carefully read the instructions for safe work with the device.
2. Stop the engine.
3. Connect the device to the battery using special clamps with strict polarity.
4. Attach the signal cable to the spark plug wire of the first cylinder to form a connection with the device.
5. When working, it is necessary to prevent wires from getting into rotating units.
6. Find the white marks on the crankshaft pulley (or flywheel) and engine housing.
7. Set the gearshift lever to neutral.
8. Start the engine.
9. Using dielectric gloves and waiting for the idle speed to stabilize, slightly loosen the bolt for fastening the turns of the distributor.
10. Use the strobe lamp to highlight previously found marks.
11. Slowly rotate the distributor body to match the marks.
12. Turn off the engine.
13. Turn off the appliance.
14. Fixing the body of the distributor, you should test the vehicle.

Strobe replacement device

Thanks to the use of this device, it is quite easy to set up the ignition. But there are situations when it is necessary to adjust the lead angle without this device. Setting the ignition timing without a stroboscopeis also possible. In this case, the driver should not despair, because you can use an ordinary neon lamp. True, you will have to work at a darker time of the day.

It is forbidden to carry out work on setting the ignition angle in an enclosed space. Exhaust fumes can be a source of fatal poisoning. Additionally, when carrying out repairs, you will need a medium-sized flashlight in order to protect yourself from getting into the working parts of the car. The device that will replace the stroboscope should be made independently. To do this, you need to take a piece of 15 mm plastic pipe and fix a converging lens on one side. A neon lamp of the TN-0, 3 type must be placed inside the tube. Another type can also be used. The main thing is that it fits in brightness. Two wires must be removed from the lamp, one of which will be connected to the mass of the car, and the second will be wound on the high-voltage wire of the candle of the first cylinder. It is necessary to wind 10 turns over the insulation. The wires must be with a thick wall of insulation, while they are not screwed to the lamp, but soldered.

When working with a homemade device, you can not hold it in your hands, as a breakdown of the insulation of the high-voltage wire of the candle may occur and, as a result, you can get serious injury. The device should be placed in a convenient place so that the light from the neon lamp, passing through the lens, hits the mark. Thus, the ignition timing is set toengine.

Working procedure using a substitute

When working on setting the advance angle, sparks in the engine compartment should not be allowed.

The work of setting the ignition depends on the brand of the engine. Setting the ignition timing without using a stroboscope is carried out according to the same principle as using it:

1. Need to start the engine in neutral.
2. Then, looking at the offset of the marks, slowly turn the cover of the distributor.
3. When aligning marks, the process should be stopped.

Note. It must be remembered that the part illuminated by the pulsed light appears to be static.

Ignition check on diesel units

Diesel engines almost do not differ from gasoline engines in some properties, but they are also demanding on the ignition setting. Setting the ignition timing of the Volkswagen T-4 will be the main example for considering repair work. Preliminary work will be carried out using a stroboscope and a tachometer.

Adjustment is made immediately after installing the ignition distributor in the event that the value of the ignition timing at idle does not correspond to the required indicators.

1. If the car has air conditioning, you must turn it off. The engine, in turn, should be warmed up to average operating standards, that is, the coolant temperature should be 80 degrees.
2. After warming up, stop the engine.
3. Next, the tachometer is connected to the 1st and 15th terminal of the ignition coil. The ignition must be turned off at this point.
4. The stroboscope connects according to the rules of polarity to the battery. A separate clamp is connected to the I/O wire of the first cylinder.
5. Next, the hose must be removed from the pressure control valve to vent the engine. It is worth diverting the hose so that in the end only clean air enters it.
6. Next, you need to start the engine, alternately letting it run both at idle and at high speeds. Once the fan kicks in, leave only idle running.
7. Disconnect the 2-pole coolant temperature sensor connector. However, turning it off may cause the engine to stop. In this case, when restarting, the connector must be replaced. If this is not done, the ignition timing will be adjusted incorrectly.
8. If the engine does not stop when the sensor plug is disconnected, it is necessary to let it run at higher speeds.
9. The light of the strobe lamp should be directed to the crankcase. To avoid damage from the fan, it is first turned off.
10. If during flashes of the risk of the moment it corresponds to the mark, then it is not necessary to adjust the ignition.

Ignition adjustment on diesel units

In other cases, it may be necessary to adjust the ignition timing. To do this, it is enough to unscrew the locking screw a little and set the position of the distributor so that the mark coincides with the risk. Then tighten the lockingscrews. They must be tightened using a torque wrench to control the tightening force. The torque value should be 25 N/m.

After that, you need to connect the temperature sensor and sharply press the gas pedal three times. Then again look at the coincidence of the marks. In a positive combination of circumstances, measuring instruments should be removed. Do not forget about the previously disabled fan drive.

Ignition Timing - Carburetor

On VAZ vehicles, setting the ignition timing is quite simple. Even a novice motorist can handle the adjustment.

The engine, as in any case, should be turned off. Next, you need to set the position of the piston of the 1st cylinder to TDC, after unscrewing and removing the candles, and plugging the open holes with cotton wool. Next, the HF and risk mark on the ICE cover are combined. Alignment is done by turning the crankshaft with a special key 38 clockwise. As soon as the cotton wool is pushed out of the holes, the shaft is turned slowly until the marks are aligned. It is worth remembering that on VAZ cars there are three marks that correspond to the ignition timing. For example, the first mark indicates a 10 degree ignition advance, the second is 50, and the third corresponds to zero degrees.

VAZ 2107 car with a carburetor engine can run on both 92 and 95 gasoline. Therefore, for these types of fuel,adjust the ignition. To do this, you need to choose an advance angle of 5 degrees. After that, you need to install the candles in place.

What's next?

Setting the ignition timing (VAZ-2107 carburetor is no exception) does not end there.

Next, you need to take a 13 open-end wrench and slightly unscrew the ignition distributor nut. You can use a regular light bulb or take a voltmeter. One wire is connected to the mass, the second to the low-voltage outlet of the coil. After that, you need to turn on the ignition of the car and slowly turn the cover until the lamp lights up, or the voltmeter indicates voltage. Next, you need to tighten the fixing nut. This completes the ignition timing for cars with a carburetor.

Checking performance

Setting the ignition timing of the VAZ-2106 is checked in a simple way: you need to accelerate the car to a speed of 40-50 km / h, turn on the fourth gear and sharply press the gas pedal. If the ignition adjustment was carried out correctly, at this moment characteristic knocks should appear for several seconds. If detonation tapping was not heard, you need to turn the distributor housing clockwise and set the ignition again.
