An experienced car enthusiast should in many cases feel that something is wrong with the engine. Most of these signals are ignored by the novice driver until the final breakdown occurs. Correct ignition timing makes it possible to enjoy driving a car. Therefore, machine manufacturers strongly recommend adjusting it at every service. But, you can easily do it yourself.
It is necessary
- - nylon brush;
- - a cleaning cloth;
- - control lamp 12V;
- - probe;
- - starting handle.
Instructions
Step 1
Remove the engine valve cover. Place the mark on the crankshaft pulley opposite the middle mark (5 degrees) on the front cover of the engine and align the mark on the timing gear (timing) with the mark on the camshaft cover. The normal operation of the internal combustion engine is ensured by the correct setting of the ignition timing (advance). Due to late ignition, the engine loses in power, since complete combustion of fuel does not occur, in addition, it overheats, loses throttle response and consumes much more fuel than it should. At an early moment of ignition, detonation knocks appear, valves and pistons can burn out.
Step 2
Set the piston of the first cylinder to top dead center (TDC). To do this, unscrew the plug in this cylinder, insert a small plastic or wooden stick into this hole, slowly turn the crankshaft. At TDC, it will stop and slowly begin to decline. The order of the cylinders: 1-3-4-2.
Step 3
Take a nylon brush, a cleaning cloth, a 12V test lamp, a dipstick and a starting handle. The most reliable and simple way to set the ignition timing yourself is to set it with a warning lamp.
Step 4
Remove the cover of the breaker-distributor. Set the octane corrector nut to the "0" position. Connect one end of the lamp wire to the "+" terminal (the power wire that goes from the ignition coil to it), and the other to the "-", ground.
Step 5
Turn on the ignition and turn the crankshaft slowly with the starting handle, watching the control lamp. The moment the lamp comes on, notice if the mark on the pulley matches the mark on the timing case cover. If this does not happen, change the ignition timing with the octane corrector nut. One turn per division is equal to one degree of engine crankshaft rotation. The adjusting margin using the octane corrector is from -5 ° to + 5 °.
Step 6
Set the octane-corrector nut to the "0" position and slightly unscrew, to move, the nut of the plate that secures the ignition distributor. This should be used in the case when it was not possible to establish the ignition moment by adjusting the octane of the corrector.
Step 7
Align at the same time the mark on the crankshaft with the mark on the front cover of the internal combustion engine and the mark on the timing gear with the mark on the camshaft cover. Connect the test lamp as in the previous paragraphs. Slowly turn the distributor body around its axis until the lamp lights up. Secure it in this position. Start the engine. Check its operation by ear for detonation knocks or interruptions. If so, use the octane corrector to achieve smooth operation. Finally check the ignition timing while driving.
