15 types of Pajero burn engine oil, what is the reason for Pajero to burn engine oil

Hello car owner, the new car should not burn, there is a problem can also claim, I wish the car a happy [car problems, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

If the oil is very serious, it must be overhauled, and if it is not serious, you can add some repair agent!

Only the oil is added more often.

Cylinder, piston, piston ring wear exceeds the limit (including piston ring adhesion, stuck, matching, breakage, etc.);

Worn valves and ducts, damaged oil seals;

The engine oil was not replaced on time, and the water sample was serious;

Excessive oil filling; ......

Burning engine oil, generally the valve oil seal is broken, there are also cylinder gaskets, burning engine oil car, exhaust pipe outlet can see a lot of carbon black and oil stains, increase the throttle when the blue smoke, if it is the above situation, it is recommended to replace the valve oil seal, one day can be done. If not, it should be checked for leakage.

Automobile engine oil can be divided into three situations: cold car oil burning, accelerated engine oil burning, and burning engine oil in any situation.

1. Burn the engine oil when the car is cold.

Generally, the cooling of the car refers to the first time in the morning to burn the oil.

Judgment method: When you get on the car for the first time in the morning, there will be a relatively thick blue smoke coming out of the rear exhaust pipe. After a period of time, the blue smoke disappears, and there is generally no similar situation on the day (if the previous situation has been in place for a long time, there may be blue smoke when the engine is stopped in place for a long time).

The same problem occurred the next morning, and otherwise there was no blue smoke. If this happens to your car, it is a cool car burning engine oil.

Cause of failure: Due to the long-term use of the valve seal, the valve oil seal is aged and worn seriously, and it has been unable to achieve a good sealing effect. When the engine is not running for a long time, the oil flows into the cylinder through the valve oil seal under the action of gravity.

When the engine is started, the oil in the cylinder burns under the action of high temperature and high pressure, producing a large amount of blue smoke.

2. Burn the engine oil when accelerating.

Judging method: when the driver slams on the accelerator or when the car slams on the accelerator when the vehicle is moving, a large amount of blue smoke is discharged from the exhaust pipe, and when the driver slams the accelerator when the vehicle is moving, the driver can see the blue smoke from the reflector on the exhaust pipe side.

Cause of failure: Due to the piston ring on the engine piston is not tightly sealed in the cylinder wall, the oil jumps directly from the crankcase to the cylinder during rapid acceleration, resulting in oil burning.

3. Burn engine oil under any circumstances.

Hello. The car will wear out internally after a long time, and the burning of engine oil is generally caused by the aging of the valve oil seal and excessive wear of the piston ring and cylinder wall. If the oil burn is serious, it is better to repair it as soon as possible.

Mitsubishi V73 77 has the phenomenon of burning engine oil under high-speed working conditions, and the oil consumption of the engine oil above 120 per hour is large. The machine itself does not burn the oil, generally the crankshaft exhaust pipe pumps the oil to the intake branch pipe and burns it.

The reasons for burning engine oil in Pajero V73: 1. The reason for burning engine oil is that the piston is counterparted, and the gap between the cylinder wall and the piston is too large, one is that the cylinder barrel is worn too much, and the other is that the piston stool is worn too much or the piston ring fails; When the cylinder barrel is worn too much, and the dead center of the piston forms a "table", there is also uneven wear of the cylinder barrel, and when the driving cone or ellipse, the oil replaced by the piston ring will accumulate and participate in combustion; When the piston is worn too much or the piston ring loses its elasticity after long-term use, the sealing is not tight, and too much oil is brought into the combustion chamber to participate in the combustion attack, which will also form a burn-in; 2. The cylinder head burns oil because the valve guide is worn and the gap is formed, the oil leaks into the combustion chamber and/or the valve oil seal is aging, and the sealing degree decreases, resulting in the oil extending the valve flowing into the combustion chamber. When the engine oil is slight, you can roughly judge the fault location by observing the exhaust

If the engine oil is burned when the car is cool, it is most likely the valve oil seal; If the engine oil is burned in a hot car, it is most likely a piston or piston ring; 3. When the oil is burned severely, it is difficult to judge whether the cylinder block or the cylinder head burns the oil, the engine must be disassembled for inspection, and sometimes the piston must be poked out of the cylinder barrel, and the roundness and taper of the cylinder barrel must be measured with an inner diameter micrometer to judge.

Mitsubishi Pajero uses 5W30 engine oil, but it can be adjusted according to specific conditions, such as the car's driving environment, the buyer's safe driving style and its service manual. When changing the engine oil, the Mitsubishi Pajero V6 generally adds up and down engine oil, and people who buy a car should keep in mind that it is not suitable for too much and not too little. Otherwise, it will cause certain harm to the operation of the engine.

Too much oil will easily lead to an increase in the load of the engine and endanger the driving force; After a long time, the engine organic exhaust exhaust system is also easy to destroy, the carbon deposit increases, and too much oil will continue to lead to the illusion of burning engine oil. The remaining oil of the engine oil is too low, which will generally endanger the overall smooth practical effect of the engine, especially many components that rely on the engine crankshaft to splash smooth, and the damage will be aggravated or even destroyed.

The selection of viscosity level, generally in winter, many areas can apply 5W engine oil, while some areas in the northern region (such as Harbin) try to apply 0W lubricating oil to obtain faster cold start characteristics to meet the local working temperature. For high temperature viscosity, 20 is generally used, but if it is often safe to drive on crowded roads, the car is very old, and the light-loaded vehicle travels long-distance and freight, etc., the viscosity of the engine oil can be moderately increased, such as the application of 0w30 lubricating oil.

Self-priming engines do not have high oil requirements, mineral oils and semi-synthetic oils can be used, and if the customer's economy allows, full-generation engine oil can be used. Compared with the self-priming type, the turbocharger engine has a closer engine structure, more stringent working standards, and the applied lubricating oil products are more advanced.

Choose a well-known brand of engine oil, focus on the longevity of the oil chain fluid, and can use Castrol engine oil; Pay attention to the cleaning of engine oil on the engine, and propose to select Shell engine oil; For motor oils with strong slick ductility, Castrol is proposed. Turbocharger engines, for example, are prone to carbon build-up at high speeds, so Shell oils with strong cleaning capabilities are available.
