The ignition system is one of the main systems in a car. If the ignition timing is set incorrectly, the engine will overheat, will not develop full power, fuel consumption will increase significantly, and detonation will appear. You can use a stroboscope to check the ignition timing. You can install it both at the service station and on your own.
Instructions
Step 1
Disconnect the vacuum hose from the vacuum corrector. To check the ignition moment, connect the plus terminal of the stroboscope to the "plus" terminal of the battery. Connect the “minus” clamp of the stroboscope to the “minus” of the battery.
Step 2
Remove the high-voltage wire from the socket of the first cylinder of the distributor sensor cover. Insert the strobe sensor in this place and connect the high-voltage wire to it. Remove the rubber plug from the clutch housing hatch. Start the engine, set on it, according to the tachometer, the crankshaft speed in the range of 820-900 rpm.
Step 3
Direct the light flashing stream of the stroboscope into the hatch of the clutch housing. The mark on the flywheel will appear stationary in the flashing light. If the ignition timing is set correctly, then it will be between the middle and the previous scale divisions. If not, adjust the ignition timing.
Step 4
Loosen the nuts securing the distributor sensor slightly. To increase the ignition timing, turn the distributor sensor housing clockwise (the "plus" mark on the flange of its housing to the projection on the drive housing). Note that one graduation on the flange corresponds to 8 degrees of crankshaft rotation. To decrease the angle, turn the valve housing counterclockwise (the minus mark is towards the protrusion on the housing).
Step 5
Stop the engine. Remove the cap from the first cylinder spark plug. Unscrew the candle. Set the piston to top dead center. To do this, insert a long screwdriver into the hole of the spark plug and, rotating the crankshaft by hand, stop it at the moment when it stops and begins to drop. Remove the clutch housing rubber plug. At this point, the average mark on the flywheel should be right in front of the notch on the scale.
Step 6
Open the cover of the distributor sensor and, holding it with your fingers to remove the gaps, align the rotor mark and the stator petal in one line. Fasten the distributor sensor. Check the ignition setting with the engine warm at a speed of 60 km / h on a flat road. To do this, sharply press the accelerator. If temporary knocking is felt, which quickly passes, then the ignition timing is set correctly.
