What is the sensor of the cylinder burst, what is the engine cylinder burst?

The fastest and most effective way to suppress knocking is to delay the ignition advance angle and reduce the combustion pressure. Therefore, the detonation sensor actuation principle is that when the engine knocking is detected, the ignition advance angle will be delayed to the ignition time when the detonation will not be detonated, and then the ignition will be slowly restored in advance when the engine does not detonation. The knock sensor uses an accelerometer to measure the change in the acceleration of the engine, that is, the vibration.

When the engineer adjusts the knock sensor, the knock vibration pattern is written into the ECU, and once the knock sensor detects the vibration pattern, the ECU determines the engine knock and then delays the ignition advance angle. The more advanced knock sensors can even determine which cylinder is knocking, and for that cylinder to delay the ignition advance angle individually.

When it comes to cylinder bursting, everyone is most concerned about what gasoline to add. In fact, or 98 is the knock resistance of gasoline, which is its "octane number". What is "octane"?

When studying the relationship between fuel and detonation, the researchers found that "isooctane" was the most resistant to detonation, while "n-heptane" was quite prone to detonation, so they set the detonation resistance of isooctane at 100 and n-heptane at 0. The so-called gasoline with an octane number of 97 is that its knocking resistance is the same as that of a mixture of 97% isooctane and 3% n-heptane.

So it's purely a matter of knock resistance, not that the higher the octane gasoline, the more powerful the engine will be. Of course, if you add gasoline with too low octane number and cause detonation, or if the engine recedes when the detonation occurs when the detonation occurs, the car will indeed be weaker. In other words, as long as the engine doesn't knock, increasing the octane rating of the fuel won't make the engine more powerful or fuel-efficient, it will only shrink your wallet.

1. Cylinder explosion: Because the piston ring and the cylinder wall lose the seal, the oil used for lubrication under the piston will enter the combustion chamber, and the white smoke is produced after the oil is burned, which is a common smoke scene on the racing track.

Second, the cause of the car cylinder burst:

1. Design defects.

In fact, the main reason for the occurrence of the car cylinder burst is the quality of the car, which is the defect of the car design, which makes the temperature of the engine exceed the maximum temperature that the engine can withstand, resulting in the engine burst.

2. Poor quality and poor operation of the oil.

In addition to the defects in the design of the car, the engine burst is also related to the quality and operation of the car oil. Poor quantity in the engine or poor lubrication caused by poor oil operation can lead to serious problems with heat dissipation, which can also cause engine cylinder blowout.

3. The engine load is too high.

There is also a reason for this due to the overuse of the engine. Excessive use of the engine due to excessive working load will cause the so-called cylinder burst or cylinder shrinkage.

4. The intake and exhaust system and ignition time of the engine are not accurate.

The inaccurate adjustment of the engine's intake and exhaust system and ignition time caused time errors is also a cause of engine cylinder burst.

The master of Luohuaxuan doesn't know how to pretend to understand.

Do you know how a car engine works?

A cylinder burst does not refer to a cylinder burst.

Instead, the piston ring loses its seal with the cylinder wall.

The lubricating oil under the piston escapes into the combustion chamber.

The white smoke is produced when the oil is burned.

Loss of engine power.

Rather, it is a completely burned engine oil.

Sprayed through the exhaust pipe to stay on the track.

And not what gasoline.

The explosion of the cylinder in the F-1 refers to the pulling cylinder.

And the real sense of the cylinder explosion should actually be written as "holding the cylinder".

It was the piston because of the lack of oil cooling.

The piston expands when the temperature is too high.

Locked in the cylinder can not move.

This condition does not produce smoke.

If you drain all the oil out of the engine.

Then drive a few tens of kilometers.

The engine is 100% holding cylinders.

Correct: blue smoke is burning engine oil, white smoke is too much water vapor in the cylinder, and white smoke is produced after the mixture is burned!

Black smoke is produced by incomplete combustion of the mixture.

What causes a car cylinder burst? Figure out what can save lives, don't be careless!

Cylinder detonation: Due to excessive temperature, the piston expands and gets stuck in the cylinder, causing the engine to be scrapped. In severe cases, the piston cannot move due to excessive pressure, and a thick flame will be spewed.

Cylinder pulling: Because the quality of the piston is not up to standard, or the temperature is too high during operation, the piston is deformed and rubbed against the cylinder wall, which causes scratches on the cylinder wall, resulting in poor closure and power loss. In severe cases, it will emit blue-blue smoke.

The reasons have been explained above.

Gasoline is burned in each cylinder to produce energy that pushes the piston back and forth through the transmission system to drive the wheels. The movement of this piston is not infinite due to physical conditions, we often see the rev of the F1 engine rev 17,000 to 18,000 rpm is this limitation, if the research and development capability is high, the engine speed is high, the speed of the relative drive wheel is faster. If the driver is not careful and keeps the engine at a high rev all the time, the combustion chamber will disintegrate because it cannot withstand such high temperatures, which is a cylinder burst, and usually after a cylinder burst, we can see a white mist liquid spilled all over the track, that is, a gasoline leak from the engine.

This is usually the case with old cow cars.

Of course, there are many factors that cause engine overheating and cylinder pressure to be too high, such as the engine output at maximum speed for a long time (such as hanging the neutral throttle for a period of time, other gears are the same) or sudden downshifting at high speed, which will also cause the engine to overheat. These are caused by improper driving by the driver. If it is the car's own fault, there are many factors, but they will cause the engine to overheat.

For example: the failure of the heat dissipation system, the short circuit of the electrical system, the increase of engine output power, causing overheating, the piston melting and the cylinder block become one, resulting in the engine inside is like a pressure cooker, and the pressure is too high to a certain extent. But seriously, the crisp **sound when the cylinder bursts and the appearance of various liquids flowing out after ** are so cute, it's just art!

I saw a Jeep Wrangler burst the cylinder, when he was climbing out of the mud pond, because the driver did not look at the tachometer and kept stepping on the accelerator, finally burst the cylinder, expensive enjoyment! If you give me 100 million yuan, I will buy one car from all brands in the world and see which of them has the cutest car with a cylinder!

Running out of oil, or using oil for too long, or the engine plant practices high-speed operation, causes the engine piston and cylinder block to be connected.

The engine is overheating and the engine cooling system is not working properly.

It's good to explode.

Maybe it will change back to v10 again.

v12 is better.

Some people also use this term to knock the cylinder and knock the cylinder and detonation.

The piston ring on the piston is stuck in the cylinder liner.

Automobile cylinder burst refers to the high engine temperature, resulting in piston expansion and deformation, stuck in the cylinder, resulting in engine scrap. When the cylinder of the car is severe, the piston cannot be activated due to excessive pressure, and a thick flame is spewed.

After the gasoline engine enters the combustion chamber, the combustion process is very complex, and it needs to be quite accurately designed and controlled. To put it simply, cylinder bursting is an abnormal pressure in the combustion chamber caused by abnormal combustion.

A cylinder burst can wreak havoc on the engine and often require major repairs to recover. So what to do if you encounter a car cylinder burst?

1. First make sure that the engine is in a flame-out cooling state, and remove the radiator cover;

2. Open the drain plug at the bottom of the radiator and let the coolant flow into the barrel;

3. Close the drain plug and fill the radiator with water;

4. Turn on the engine, turn on the heater control system, add cooling system cleaner, and empty the engine for 30 minutes;

5. Turn off the engine to cool down for 5 minutes, and drain the liquid in the radiator;

6. Close the drain plug, fill the radiator with water and let the engine idle for 5 minutes. Then, re-inject 50 50 water and glycol antifreeze into the coolant compound.

Under normal circumstances, the car cylinder burst will seriously damage the engine, and the engine is almost scrapped, so the owners encounter the car cylinder burst, after doing a good job of emergency treatment, they should also call the 4S shop to find professionals to repair or replace the engine.

If the water temperature in the tank is too high, it will affect the heat dissipation of the engine. A cylinder burst should mean that the piston of the engine is stuck to the cylinder liner, and the engine will quickly extinguish the fire and the engine needs to be rebuilt.

After the cylinder bursts, the cylinder cannot be tightly sealed, and the air pressure leakage will lead to a serious lack of power.

If you add water, you should use a special coolant

The temperature of water shortage is high, and the machine does not rotate after the cylinder bursts, and any water can be added.

The cylinder is still gone!? What a miracle

Do you mean to burst the tile or stick the cylinder The most common thing to burst the tile is not enough oil The sticky cylinder is the high temperature of the engine, and the piston and the cylinder barrel are glued together.

When the oil is not enough, the cylinder will burst.

When the lubrication system fails, when the cooling system fails!

The turbo boost value has been raised. It is most likely to blow up the cylinder.

High speed, of course, will cost fuel, the original 2000 rpm or so shift, now 4500-5500 fuel consumption will definitely be much higher.

If the cylinder bursts, it will not cost fuel, and the engine will be scrapped directly, and you can't run at all.

Probably not The main thing is that you may not fill it up at the beginning, and it will be gone all of a sudden. Then it is normal to dry it in plus ** big.

How to repair the motorcycle engine piston pin and crankshaft sudden death? Teach you just one trick to fix.

The holding cylinder is caused by the poor lubrication of the engine oil, if the DU is a slight zha holding cylinder, it is OK.

If it is caused by the lack of oil, you can replenish the oil first, if it is because the oil pump does not work or the oil channel is blocked, you can not continue to drive, no matter which case, it must be repaired in time, the emergency is only a temporary method on the way, and when you get to the place where there is a repair department, you must eliminate the cause of the fault in time, otherwise it will cause a greater failure.

It doesn't cost much to find a dedicated and experienced master to repair it, and you can pay attention to the oil of the gearbox in the future.

Put the spark plug off, use a syringe to inject oil into it, after the big 50ml goes in, slowly kick the starting lever, if you can move, just kick a few more, if you don't move, then you give up, the spindle is pulled to death, except for overhaul, there is no solution.

What do you mean by bursting.

If it's a holding cylinder.

Then you're going to need to overhaul the engine.

The reason for holding the cylinder.

Lack of lubricating oil.

The temperature is too high. There are foreign objects, etc., and it is inevitable that you will not be able to step on the cylinder.

There are no contingencies.

Only overhaul engines.

Replace the piston cylinder liner and piston ring.

Unscrew the spark plug, pour in 30-50ml of engine oil, and replace the spark plug, it may start, but it must be repaired.

It can't be activated.

The cylinder is caused by the melting of the connecting rod and crankshaft pad.

It had to be repaired.

The spindles are all pulled to death, and there is no solution except for overhaul.

Emergency repair: add enough lubricating oil, the best is to exceed the specified amount of several hundred milliliters.

Horizontal engine (add lubricating oil from the valve chamber cover) :d AO1, start the ordinary machine without electricity--- remove the magneto cover on the left, use a 14mm socket wrench to rotate the magneto rotor repeatedly (that is, turn the crankshaft), until it feels less heavy, and then try to start with your feet, as long as it can start, you can drive in an emergency; 2. Start the engine electrically, unscrew off the small cover corresponding to the magneto rotor from the magneto cover on the left, and stick it in with a 14 mm sleeve (some have 17) and use the method of 1.

Vertical cylinder engine: Unscrew the small cover corresponding to the magneto rotor on the left side of the engine, stick it into it with a 14 mm sleeve (some have 17), and rotate it repeatedly.

You should be holding the cylinder and overhauling.

Can they still rotate when they all burst the cylinder? Let's go straight to the overhaul.
