What is the reason why the engine of Changan Star 6363 suddenly burns oil?

If the lower exhaust drips oil, it is generally the piston ring that is seriously worn or broken, and it is the right one.

If the lower exhaust is not serious, it is generally the turbocharger seal is not tight, this can be removed from the pipes at both ends of the turbocharger to see if there is any engine oil, to determine whether it is a turbocharging problem.

Poor sealing of the valve oil seal will also burn the engine oil, which is relatively low.

Hello. The 16-valve engine of our parent safety 6363 is caused by excessive wear of the gap between the cylinder liner and the piston, and the 8-valve engine is caused by insufficient torque of the cylinder head screw. Hope it helps.

It feels like a sign that the engine is pulling the cylinder at a high temperature, and it is recommended to repair it as soon as possible.

Phenomenon Hope.

The reason for the oil burning of Chang'an Star car:

1) Natural wear and tear. With the increase of the mileage of the car, the wear between the piston and the cylinder gradually increases, when the wear increases to a certain extent, the cylinder blow-by will begin, and then the phenomenon of burning engine oil will occur. When the valve oil seal is damaged, it will make the oil burning phenomenon more obvious.

2) Improper maintenance.

1) Maintenance of the engine according to the specified mileage will prolong the service life of the engine. On the contrary, even if the mileage is exceeded and not insured (i.e., the insurance is delayed). If the oil is too dirty, the impurities in the oil will accelerate the wear of the engine cylinder.

2) Too much oil is added.

3) Improper selection of air filter element, machine filter element, engine oil, etc., the gas impurities entering the cylinder can not be well purified, and all kinds of dust particles enter the cylinder, accelerating the wear of the cylinder. The quality of the filter element is poor and does not play the role of the magazine in the filter oil. Counterfeit engine oil or the oil used does not match the oil grade of the vehicle used, so that it will not be able to form a good oil film on the friction surface of the engine.

4) Ignition too early or too late. Premature or late shock will increase the temperature of the engine, and in severe cases, the piston will fall off the top and the cylinder block will be scrapped. In its initial stage, there will be serious cylinder blow-by gas and burning engine oil.

6) There is too much dirt in the water tank in the cooling system. The radiator and condenser are too dirty, which reduces the ventilation and heat dissipation capacity, and increases the normal working temperature of the engine. Due to the high temperature, the quality of the oil film produced by the lubricating oil during friction decreases, and the wear of the cylinder is intensified.

To sum up, in addition to the natural wear and tear of the vehicle with the increase of vehicle mileage and the generation of engine oil, active maintenance and reasonable use of the vehicle can avoid the early arrival of the cylinder blow-by phenomenon and prolong the service life of the car.

The main phenomenon of burning engine oil is the exhaust pipe emitting blue smoke, and the oil consumption in the engine is significantly increased.

In fact, there are two reasons for the failure of burning engine oil. One of the oil enters the cylinder through the piston ring and the other through the intake valve. The judgment method is to measure the cylinder pressure, if the pressure is low and the engine is weak, it should be caused by the wear of the piston ring cylinder.

If the pressure is normal and the engine does not drop under motion, it is generally caused by the wear of the valve oil seal and valve guide.

After a few years of use, the pistons, piston rings, steel body and valves are worn out, which will burn the oil.

The car is too old, and the main reasons for spontaneous combustion are: electrical accidents, open fire accidents, old electrical appliances, many peripherals are installed and the installation is not standardized, and the power is large, and the wire diameter at the connection can not withstand the large current, resulting in overheating**.

Open fire accidents were mainly smoking.

The engine should be clean, and the heat outside the machine will be affected by a thick layer of ash in summer, and the pipeline passing through the engine will be prone to accidents if it is baked at high temperatures.

Looking for the above aspects will definitely prevent accidents.

Valve seals are damaged, piston rings, cylinder liners, and pistons are worn too badly.

My Chang'an Star 6363 is also the same problem, the engine, chain throttle, intake pressure sensor, four fuel injectors, four spark plugs, cylinder wire, distributor, high-pressure ignition coil, stop valve, oil pump, all new, or can't afford to refuel, don't hang the gear to refuel, feel okay, hang the gear to refuel, can't add, it feels like the feeling of going off, hey, the local car repair master is also no way, ask the master to give a pointer thank you for my Chang'an Star ( check the transaction price |Model details ) 6363 is also the same problem, engine, throttle, intake pressure sensor, four fuel injectors, four spark plugs, cylinder wire, distributor, high-pressure ignition coil, stop valve, oil pump, all new, or can't add oil, don't gear refueling feeling OK, hang gear refueling, can't add, it feels like it's going to turn off, hey, the local car repair master is also no way, ask the master for a guide Thank you Is your car ready, mine also has the same problem 1In the case of unstable idling, the first thing to consider is the throttle, if you can't add oil, you can consider cleaning it once. 2.

When the intake manifold leaks, when the air, gasoline vapor, and combustion exhaust gas that should not enter enter the intake manifold, the mixture is too thick or too thin, causing the oil to be inadequate. 3.If there is a problem with the ignition coil or spark plug of the ignition system, it may also cause such a situation, and it is easiest to check the spark plug, and the electrode carbon deposit can be known at a glance.

4.The oxygen sensor of the intake and exhaust system is sometimes broken, resulting in inaccurate intake data and inability to fill the oil. @2019

There are many reasons for the small power, and what do you mean by small gas power?

du?Is it said that the reason for the small power of the power is caused by insufficient combustion, there are many reasons for insufficient combustion, 1>. The air intake is small, that is, the air intake pipe leaks, resulting in excessive mixed steam.

2> The amount of oil intake is less, check whether there is oil leakage in the oil pipe, and the amount of gasoline injection is less.

3> Check whether the sensor is broken.

4> is the problem of the ignition system, check the spark plug, will there be too much carbon deposit, the ignition fire is not normal, resulting in poor work of the cylinder, so that the power of the engine decreases, check whether the ignition time is normal, 5> whether the gas phase is normal.

6> If the car has been driven for a long time, check whether there will be too much carbon deposit, resulting in too large a clearance, so that the pressure of the cylinder drops, and the power will decrease.

7> Finally, I am looking to see if there is a problem with the exhaust pipe, and there are many car problems that appear in the exhaust pipe.

If it's a slight burn, you can just ignore it or buy some oil additives, and if the burn is serious, you can only overhaul the engine.

Hello. Burn oil to overhaul the engine solution.

The rings have to be replaced, and the degree of wear of the cylinder and its pistons needs to be checked, which is also closely related to the cause of oil burning.

It depends on the specific situation There are many kinds of major repairs It depends on what is repaired Change the repair shop and try it.

The engine oil itself has a certain amount of consumption, and excessive consumption is the problem of burning engine oil. There are many factors that affect the burning of engine oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc

1. Carbon deposition occurs in the combustion chamber, which makes the gas ring of the piston ring stuck, and the sealing is poor.

2. Oil sludge is generated in the lubrication system, and the oil sludge blocks the oil return hole of the oil ring and weakens the oil scraping performance.

3. Wear occurs between the piston and the cylinder wall.

4. The valve seal is corroded and aging, and the sealing performance fails.

In addition, cars now have crankcase ventilation systems (exhaust valves), which can also exacerbate oil consumption if there is a problem. In the past, the problem of burning engine oil could only be solved by dismantling and repairing, and carbon deposition would cause insufficient gasoline combustion and cause the engine to shake. The impact of engine carbon deposition on the car is quite large, first of all, to reduce the engine power, that is, to make the power output uneven and gradually decay, in other words, more and more powerless.

The second is to increase fuel consumption and increase your financial burden. Finally, the serious carbon deposition in the combustion chamber will also cause cylinder detonation, and there will be a sound of low-speed acceleration, which will cause damage to the piston and crankshaft, which will seriously affect the safety of the car. Then there is the excessive discharge, which not only fails to pass the annual inspection and inspection, but also directly aggravates the harm of polluting the environment next to the nuclear disguise.

There is another reason: the throttle valve is faulty. Both of these problems can cause engine shake and unstable speed.

Now there is a solution to the problem of burning engine oil without dismantling and repairing, which can be learned about.
