Correctly adjusted ignition timing is the key to stable engine operation and minimum operating fuel consumption. Take advantage of the optical method and tune your car's engine with a stroboscope.
Necessary
- - stroboscope for tuning engines;
- - a set of automotive tools;
- - dielectric gloves.
Instructions
Step 1
Roll the car out of the garage to adjust the ignition. Avoid direct sunlight interference, choose the afternoon for work. Inspect the stroboscope and make sure there are no mechanical damages on its body. Remember that contact with the high-voltage converter circuit of the appliance can cause you serious injury.
Step 2
Stop the car engine. Using the clamps and observing the polarity, connect the device to the battery. To avoid a short circuit in the event of an erroneous connection of the contact wires, check your actions with the instructions supplied with the device. Attach the signal cable to the wire connected to the spark plugs of the first cylinder and capacitively coupled to the stroboscope.
Step 3
Arrange the wires so that they do not get caught in the moving parts of the machine. Look for the white mark on the flywheel or crankshaft pulley. Identify similar markings on the motor housing. Remove metal objects from yourself: watch, bracelet, chain, etc. Place the vehicle's gear lever in neutral.
Step 4
Wear dielectric gloves. Avoid any contact of body parts and clothing items with moving parts of the mechanism. Start the car engine and let it warm up, achieving a steady idle speed. Loosen the mounting bolt that prevents the distributor from turning.
Step 5
Aim the strobe lamp at the crankshaft pulley, illuminating the mark on its housing and the line on the engine. Slowly rotate the distributor body in a certain direction, achieving the alignment of the marking strokes. Stop the engine and turn off the stroboscope. Fix the distributor body by tightening the mounting bolt.
Step 6
Check the ignition control in dynamics by accelerating the car to 50 km / h on a horizontal section of the road. Press the gas pedal sharply. Detonation knocks, lasting no more than two seconds, signal a positive result of your work.
