Performance, causes and solutions of Chuanqi GA4 burning oil.

The main reasons for burning oil in Chuanqi GA4 are valve oil seal, excessive piston clearance and excessive or insufficient engine oil. The performance and solutions of Chuanqi GA4 engine oil are as follows.

Valve stem seal

The valve mainly plays a sealing role to prevent oil from infiltrating into the combustion chamber. However, after long-term use, the valve oil seal will always age or be damaged, which will lead to the decline of sealing performance, and the oil will penetrate into the cylinder along the valve and burn with the fuel.

Solution: Replace the valve oil seal in time to ensure the tightness of the valve.

Excessive piston clearance

With the increase of automobile service life, carbon deposits with insufficient combustion will appear on piston rings. If left untreated for a long time, the seal between the piston ring of the engine piston and the cylinder block will loosen, which will accelerate the flow of engine oil from the crankshaft to the cylinder, causing engine oil to burn, and even "cylinder explosion" in serious cases.

Solution: Take out the piston directly and replace it with a new one. Of course, cleaning the carbon deposit on the piston ring regularly at ordinary times can effectively prevent oil burning.

oil painting

If there is too much oil, the oil pressure will be too high and some oil will be forced into the cylinder. If you don't pay attention to the amount of fuel, the vehicle will burn oil.

Solution: pump out excess oil. General repair shops can handle it, and the cost is not very expensive. Of course, you can handle it yourself. Prepare a medical syringe, then connect the plastic tube with the syringe, then grab the handle of the dipstick, pull it out and insert the plastic tube. Finally, operate the fuel injection pipe to pump out excess oil.

The problem of engine oil burning is still very serious. If the engine oil is burned in the car, not only the amount of oil decreases, but also the carbon deposition in the combustion chamber increases. When it is serious, it will accelerate the damage of oxygen sensor, appear a lot of carbon deposition, block the three-way catalyst, and even directly scrap it. Therefore, it is necessary to treat the problem as soon as possible, so as not to cause the engine to be irreparable.
