How many revolutions does the Changhe Suzuki Big Dipper have to turn

First, the ignition timing does not have a great impact on the car, the combustion of gasoline in the engine must be ignited by the spark plug jumping out of the spark, to make the engine start smoothly, and burn well, the spark of the spark plug must be strong enough, but more importantly, the time when the spark jumps out must be appropriate and correct, too early and too late will affect the horsepower of the engine, the time when the spark jumps out of the spark plug is the so-called ignition timing. It is generally expressed in terms of the angle of how many crankshaft turns before the piston goes to the top dead center, such as 10° before the top dead center, rather than in time.

2. Ignition timing adjustment.

1. Adjust the gap between the power-off contacts of the distributor.

The size of the contact gap not only affects the strength of the spark, but also affects the opening and closing of the contact. If the contact gap is adjusted after adjusting the ignition timing, even if it is a small change. It will destroy the ignition time that has been adjusted, so the contact gap must be adjusted before the ignition timing adjustment, and the gap must be adjusted to 0

35～0.40 mm range.

2. Find out the position of the top dead center of the compression stroke of the first cylinder, and loosen the spark plug of the first cylinder.

Slowly shake the crankshaft, when you hear a deflating sound, it means that the first cylinder is compressing the stroke. Open the sight hole cover on the flywheel housing and slowly shake the crankshaft so that the timing mark is aligned.

3. If there is an octane number selector, it should be adjusted in"0"on the scale position.

4. Determine the position where the contact of the cut-off is just opened.

Unscrew the fixing screws of the distributor housing, and turn the shell along the direction of rotation of the distributor shaft first, so that the two contacts are in a closed position. Then turn on the ignition switch and turn the shell of the distributor in the opposite direction of rotation of the distributor shaft while facing the high-voltage wire of the ignition coil against the tie iron (about 2 3 mm) until a spark is found. Finally, tighten the set screws of the distributor housing.

5. Connect the high-voltage line according to the ignition order

Replace the fire divider, insert the first cylinder high-voltage wire into the plug-in hole where the distributor cover and the conductive piece of the distributor head are aligned, and plug in the high-voltage wire of each cylinder in the order of clockwise direction.

6. Start the inspection:

Start the engine to run to a normal temperature, accelerate suddenly, and if the engine makes a short and slight knocking sound and disappears immediately, the ignition time is appropriate. If there is no knocking sound, that is, the ignition time is late, the fixing screw of the distributor shell should be loosened, and the distributor shell should be rotated a little in the opposite direction of the distributor shaft. If the detonation sound is severe, that is, the ignition time is early, the distributor shell should be turned in the opposite direction of the above until it is suitable.

Hello, generally the crankshaft needs to be rotated twice.

Changhe Suzuki Beidouxing K14B engine uses timing chain instead of timing belt, which reduces the cost of regular maintenance, and is generally maintenance-free and replacement-free. If there is a more serious accident in the vehicle, the chain is damaged, the steps to replace or adjust the chain are more complicated, the engine needs to be removed, in accordance with the maintenance manual, and at the same time with special tools can be completed, if the improper operation may lead to further damage to the engine, it is recommended to check and deal with the regular maintenance station.
