How many kilometers of BMW 316li timing chain is replaced

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 size of the contact gap between the power-off contacts of the distributor and 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 breaker has just opened, loosen the fixing screw of the distributor shell, and rotate the shell along the direction of rotation of the distributor shaft first, so that the two contacts are in the 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 inspection: start the engine to run to normal temperature, suddenly accelerate, if the engine makes a short and slight detonation 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.

The chain is maintenance-free for life and is not damaged and replaced.

The chain does not need to be replaced.

07 BMW 325i timing chain 150,000 km change. The transmission of the timing chain drive mode is reliable, the durability is good and can also save space, its main function is to drive the valve mechanism of the opening hole closing motor, so that the engine intake and exhaust valves can be opened or closed at the appropriate time, so as to ensure that the engine cylinder can be inhaled and exhausted normally.

Advantages and disadvantages of timing chainsThere are obvious cracks in the timing belt, which can be seen with the naked eye, and the wear of the timing belt is serious, mainly in the reduction of hardness, fiber breakage, etc. The advantage of timing belt is that the technology is mature, the cost is lower, the noise is less, and the application time is longer, and the disadvantage is that the service life is shorter.

In the future, timing belts may be replaced by timing chains. The timing chain has a compact structure, the power transmitted is higher than that of nanocracking, the reliability and wear resistance are better, and it can be free of warranty for life. When the timing chain just came out, the noise was greater than the timing belt, and until now, its noise has become very small, and the noise is smaller than the timing belt, especially the toothed silent chain, which is softer when transmitting, the impact is smaller, and the operation is more stable.

Summary. Hello dear, the 14 BMW 320i uses a timing chain. It is maintenance-free for life.

After 150,000 kilometers, it may be necessary to check whether there is elongation and whether the guide plate may be damaged. The generator still uses a belt, which needs to be replaced for 8-100,000 kilometers. The three series use the engine of the N20 series, all of which are timing chains.

Thank you dear, the timing chain life is about 15-200,000 kilometers to replace. Compared with the timing belt, the timing chain has a longer service life and a lower failure rate, and there will be wear between the timing chain and the sprocket during the operation of the engine, and there is also a certain service life. However, timing chains are lubricated by lubricating oil, and if the engine lubricating oil is not replaced for a long time or the quality of the oil is not good, it is easy to aggravate wear and tear, which will reduce the life of the timing chain.

Dear, BMW car 10,000 km maintenance cycle, after every two small maintenance, every 30,000 km to do a major maintenance. Change the oil and oil filter at every time maintenance; It is recommended to replace the air filter, air filter and fuel filter every 20,000 km; It is recommended to replace the spark plug every 50,000 km. Change the brake fluid every two years.

In addition, all BMW models are maintenance-free transmission and steering power for life, and there is no need to change the transmission oil and steering power oil.

BMW timing chains are replaced every 150,000 to 200,000 km.

The valve train that drives the engine:

Make the intake and exhaust valves of the engine open or close at the appropriate time to ensure the normal intake and exhaust of the engine cylinder.

Timing chain drive function:

The chain drive mode has reliable transmission and good durability, which can save empty hours. The whole system is composed of gears, chains and tensioning devices, among which the hydraulic tensioning device can automatically adjust the tension force, so that the chain tension is consistent, and it is maintenance-free for life, so that it has the same service life as the engine.

Durability of timing chains:

The timing chain has the inherent advantage of durability, you need to worry, you don't have to worry about "disrepair", and you don't have to worry about the chain falling off when you drive it to the market, but when the total mileage of the car reaches 100,000 kilometers, the shortcomings of the timing chain begin to appear.

318 is a timing chain.

BMW's engines are now chained, and the life of the chain is a little longer, and the chain does not need to be replaced for 200,000 kilometers under normal circumstances.

If you don't maintain it on time, the lines will be easy to elongate or wear out too much, and then replace the chain. As long as the chain is faulty, it will make an abnormal noise when it accelerates.

Hello. A timing tool is required. Taiwanese goods are about 2200 yuan.

Group words 200 at a timeCard crankshaft, card camshaft. It's not easy to operate without tools.

Welcome to the car master. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Detect the valve phase of the camshaft.

1) Turn the engine until the engine cylinder 1 is in the ignition top dead center position.

2) Remove the plug from the cylinder block (the calibration hole at the top dead center position is on the intake side below the starter).

4) Check whether the valve phase of the camshaft is correct.

1) Intake camshaft: The upper side of the double-plane segment is round, and the lower side is flat. At the 1-cylinder ignition top dead center position, the circular side on the biplanar segment is facing upwards.

2) Exhaust camshaft: The circular face on the double-plane section of the cylinder head is facing upwards. At the same time, the notch on the exhaust camshaft is directed towards the exhaust manifold.

5) Install the special wrench on the intake camshaft and try to rotate the intake camshaft in a counterclockwise direction. If there is no fixed connection between the intake camshaft and the intake adjustment device, rotate the intake camshaft in a counterclockwise direction to the limit position.
