The gasoline engine increases the throttle and emits black smoke, which consumes oil what s going on

Hello! If the engine does not leak oil, the oil will be consumed because the valve seal is aging and leaking oil into the combustion chamber to participate in combustion; Another reason is that the piston rings are worn and the oil is strung upwards, which also participates in combustion (that is, the legendary oil burning!). It is recommended that you go to a 4S shop or repair shop to check the repair!

The engine is going to be overhauled (> hope it helps! [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, the black smoke is caused by poor combustion, it may be the poor combustion affected by burning engine oil, and the engine needs to be overhauled, I am very happy about your problem, I hope it can help you, I wish you a happy car!

Hello, this situation is generally caused by the broken oxygen sensor... And the car doesn't run as hard as it used to Doesn't run fast The car is wooden I hope it will be useful to you [Car questions, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

That's burning engine oil, hurry up to the 4S store.

Hello: The black smoke of the engine is caused by the mixture being too thick, the water temperature sensor, the intake pressure sensor, the oxygen sensor, the air flow device will cause black smoke if the sensors are broken, and the main reason for burning the engine oil is the piston ring grinding counterpart, the cylinder caused by high temperature, and the valve oil seal is not well closed.

I hope mine can help you and I wish you a happy ride. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Black smoke is also known as soot, and the black smoke from the exhaust of diesel engines is mainly caused by the excessive concentration of fuel mixture, poor formation of combustible mixture or imperfect combustion.

1. The most common air filter is blocked.

2. The grease nozzle does not spray dripping oil.

3. It is a problem of ignition time, which generally has little impact on fire, and the sound of oil supply time is crisp and blue smoke in the morning, and it is convex or white smoke when it is late.

4. There is a problem with the oil pump and the plunger pressure is not enough.

5. Check whether the screws of the vacuum tube of the supercharger oil pump are loose, and whether the pipe of the supercharger is loose.

6. Look at whether the engine belt is air-cooled, and if the air-cooled is dirty, it will not emit black smoke, and there should be no problem with anything else.

Diesel engine black smoke fault self-diagnosis steps:

1. Remove the air filter and check whether the air filter is blocked, clean and unblocked.

2. The intake resistance of the intake pipe is large, check whether the inlet pipe has a leakage point, or the squeezing deformation causes blockage, and observe the change of exhaust smoke.

3. Replace the diesel filter element and observe the flue gas changes of the exhaust pipe.

4. If the injector, high-pressure pump plunger or oil outlet valve is faulty, observe the flue gas change after replacing the injector.

5. The turbocharger is faulty and the speed is not enough, resulting in black smoke from the engine.

When black smoke is emitted, it is often accompanied by a decrease in engine power, too high exhaust air temperature, and too high water temperature, which leads to wear of engine parts and reduces engine life. The causes of this phenomenon (there are many causes of incomplete combustion) and how to eliminate them are as follows.

1) The exhaust back pressure is too high or the exhaust pipe is blocked. This situation will cause insufficient air intake, which will affect the air-fuel mixing ratio, resulting in excessive oil volume. This is the case:

First, there are too many exhaust pipe bends (especially 90° bends), which should be minimized; The second is that the inside of the muffler is blocked by too much soot and should be removed.

2) Insufficient air intake or blocked air intake duct. In order to find out the cause, the following checks should be carried out: first, whether the air filter is blocked; the second is whether the intake pipe is leaking (if this phenomenon occurs, the engine will be accompanied by a harsh whistling sound due to the increase in load); The third is whether the turbocharger is damaged.

The blades of the exhaust gas wheel and booster wheel should be checked for damage and whether the rotation is smooth and flexible; Fourth, whether the intercooler is blocked.

3) Incorrect adjustment of the valve clearance, poor contact of the valve seal line. Valve clearance, valve springs and valve seals should be checked.

4) The oil supply of each cylinder of the high-pressure oil pump is uneven or excessive. The uneven oil supply will produce unstable speed and intermittent black smoke, which should be adjusted to make it balanced or within the specified range.

5) If the injection is too late, the advance angle of the injection should be adjusted.

6) If the injector is working poorly or damaged, it should be removed for cleaning and inspection.

7) Injector model selection is incorrect. Imported high-speed engine has strict requirements for the selected injector (injection hole diameter, number of holes, injection angle), if the choice is not appropriate, it will also cause the engine to emit black smoke, even if the same model of engine, in different use occasions (output power, speed, etc.), the injector model required to be used is not the same. If the incorrect injector is selected, the correct type of injector should be replaced.

8) Diesel is of poor quality or the grade is wrong. The imported high-speed diesel engine equipped with a direct injection combustion chamber with a porous injector has strict requirements for the quality and grade of diesel due to the small aperture and high precision of the injector, otherwise it will also cause the engine to emit black smoke and even make the engine unable to run normally. Therefore, clean and qualified light diesel oil should be selected, and it is recommended to use 0 or +10 in summer, -10 or -20 in winter, and -35 in severe cold areas.

9) The wear of cylinder liner and piston assembly is serious. When this happens, the piston ring seal is not tight, and the air pressure in the cylinder drops seriously, resulting in the diesel fuel can not be fully burned and black smoke is emitted, and the engine power drops sharply. Wear parts should be replaced.

If there is black smoke, generally speaking, the combustion is not sufficient, focus on checking whether the amount of fuel injected is too much, you can remove a fire plug, check the color of the fire plug.

Most of this phenomenon is caused by too much fuel, and the fuel system must be checked. If it is an old gasoline engine with a carburetor type, you can clean the carburetor, check the injection volume holes, etc. In the case of an EFI fuel system, a computer must be used to detect whether the system is faulty.

The gasoline engine increases the throttle and emits black smoke, which consumes oil what's going on

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, I am your exclusive technician, attentive, careful, concentrate on answering your car questions, for you to find the corresponding problem solutions and solutions, your problem is black smoke, oil consumption, first, black smoke, in general, the mixture is too thick, or burn engine oil, second, if it is a Volkswagen car, first check the oil and gas separator, and the upper exhaust valve, if other cars, the oil-water separator to check it, in check the valve seal, piston ring, whether the wear is too large.

Mini car gas oil truck.

The new car is a little more than a year old and does not have any fault code display.

Well, check the quality of the engine oil and see if the fuel injector is leaking.

It's all normal. Is the oil consumed too much, check the oil-water separator.

It's all replaced, but I can't find the problem, and the spark plug is also gone, and there is no carbon deposit.

If the oil burns too much, then you have to disassemble and check, the valve oil seal, the piston ring.

Black smoke from gasoline engines is a common phenomenon, mainly because the mixture in the engine is too thick, resulting in insufficient fuel combustion. This phenomenon is also a major manifestation of engine failure. There are many reasons for this failure and need to be checked one by one.

When the air filter used in the car is too wide and dirty, the ignition condition of the spark plug is not good, and the ignition coil fails, it will cause black smoke from the engine exhaust. If the car emits black smoke, it is recommended to go to the repair shop for inspection in time.

In addition, in the process of using the car, it is necessary to go to the designated gas station to refuel. A similar situation can easily occur when you use low-quality gasoline, because low-quality fuel can greatly reduce the efficiency of the engine.

The air filter should be replaced regularly. After long-term use, the mixture will be too thick, which will easily lead to insufficient oxygen supply during the working process of the engine, and lead to insufficient fuel combustion in the engine.

During the car repair process, it is necessary to pay attention to check the working condition of the spark plug. If the car is in a state of poor ignition, it will cause the engine to emit black smoke while working.
