The cause of the problem of burning engine oil in the new Sylphy has been found, has it been solved?

Because the injected fuel is of poor quality, it is easy to produce carbon deposit, which will aggravate the wear between the piston and the cylinder wall, produce an excessive gap, and cause the oil to enter the combustion chamber.

Carbon deposition in the piston ring groove of the engine causes the piston ring to stick together, which leads to the piston ring being stuck and unable to be completely sealed. The "stuck" piston ring greatly reduces the oil scraping sealing ability. In addition, sludge will also block the oil return hole, and the oil will not flow back normally, resulting in an increase in fuel consumption.

The valve oil seal is corroded and aged, and the seal is not tight. It can be said that the valve oil seal is the most vulnerable part of the engine, and this problem basically exists in cars that have traveled more than 654.38+ 10,000 kilometers.

The front and rear crankshaft oil seals are aging, and the front and rear crankshaft oil seals are in continuous contact with oil in a large area. Impurities in the engine oil and continuous temperature changes in the engine gradually weaken the sealing effect, leading to oil leakage or oil leakage.

The air filter is blocked and the throttle is dirty. Will lead to poor intake, reduce intake pressure, form negative pressure, so that engine oil is sucked into the combustion chamber under negative pressure, resulting in engine oil combustion. The oil filter is blocked, resulting in an increase in oil consumption.

Engine oil contains a high proportion of fuel. If the oil supply system is not working properly and the fuel atomization is not good, the fuel or a large amount of over-concentrated fuel mixture will run into the crankcase to mix with the engine oil and dilute the engine oil.

The oil seal between turbocharger and intake pipe is damaged. The main reason is that the floating turbine spindle lacks lubrication and heat dissipation due to the long oil change cycle or the use of inferior oil, thus damaging the oil seal.

Solution:

Replace the engine oil and oil filter with better quality. The oil filling amount should not exceed the upper limit, otherwise the oil may burn in the catalytic converter, resulting in damage to the catalytic purifier. Can clean the internal circulation of the engine.

Clean the air filter and throttle oil sludge to ensure normal air intake.

Use better quality fuel, add fuel cleaner to clean the pipeline to reduce carbon deposition, and clean the injector.

Don't step on the accelerator when using the vehicle at ordinary times. Stepping on the accelerator will accelerate the phenomenon of slight refueling.
