2.There is too much oil in the engine fuel. 3.
Poor piston ring or crankshaft oil seal sealing. 4.There is moisture in the fuel.
5.Bad spark plug 6The air filter is too dirty.
2. Fault diagnosis and elimination.
1.For the inspection and diagnosis of excessive concentration of combustible mixtures, the carburetor and air filter should be checked.
2.The blend does not compare with the blend of the oil, or the wrong grade of oil is used. If the oil mixture contains too much oil or the oil quality is poor, the oil of the flammable mixture cannot be completely burned, resulting in black smoke.
The above phenomenon can also occur in two-stroke engines with separate lubrication and oil pump misalignment and excessive oil supply. At this time, the oil pump should be checked and adjusted according to the regulations to ensure that the lubricating oil is supplied proportionally at different throttle openings.
3.Excessive wear or breakage in a four-stroke engine, as well as too much oil in the crankcase, can cause oil to string into the combustion chamber and cause excessive oil in the mixture. If the crankshaft oil seal of a two-stroke engine is broken, it will also cause the oil from the transmission to string into the crankcase and enter the combustion chamber with the mixture.
4.One of the reasons for the mixing of water in the fuel is that the fuel in the fuel tank itself contains water, so the fuel tank should be cleaned and the fuel should be replaced. Another reason is that the cylinder gasket of the water-cooled engine is broken, and cold water enters the cylinder.
If, in the absence of leakage, the water in the tank is consumed too quickly, and the exhaust smoke from the exhaust pipe is slightly white, this is mostly the reason and the head gasket should be replaced.
Black smoke from gasoline engines is rare, black smoke is mainly not completely burned fuel in the combustion chamber, in the case of high temperature and lack of oxygen, diesel can not be completely and fully combusted, so decomposition and aggregation to form soot, it is a small diameter of the aggregate.
Because this aggregate reacts much slower than gasified fuel, due to the high temperature and anoxic environment of the combustion chamber, it cannot be fully burned again and is discharged through the exhaust pipe, so black smoke is presented.
The direct consequence of this phenomenon is that the fuel consumption of diesel engines is very high, the power is reduced, and at the same time, a large amount of carbon deposits exist in the piston and piston ring valves. In severe cases, the piston rings will be jammed, the valve seal is not tight, and the air leakage will be accelerated, and at the same time, it will also accelerate the wear of parts, thereby reducing the service life of the engine, so this aspect should be paid special attention.
Oil spills. There are usually several reasons for oil leaks:
1. Valve oil leakage, valve oil leakage is generally because the valve is blocked or damaged, and the solution is to replace the valve.
2. The joint is loose, and the solution is to tighten the joint or replace the joint.
3. That is, you have problems with the pump and hydraulic oil pipe.

Anonymous users2024-02-13Summary. Hello, I am your exclusive service technician, attentive, attentive and careful to help you solve the problem of using the carBora idling fire and white smoke This situation mainly considers the following reasons. The first common aspect is whether the ignition defect caused by the addition of ordinary inferior gasoline to the oil quality problem is a failure.
The second common problem is that the ignition system failure mainly includes leakage of the ignition coil, too large gap of the spark plug, and poor ignition. The third aspect is mainly the group side, which mainly includes the problem of poor combustion caused by throttle deposition, fuel injector deposition and in-cylinder carbon deposition. Fourth, I would like to consider the sensor, which is generally the oxygen sensor.
Hello, I am your exclusive service technician, attentive, attentive and careful to help you solve the problem of using the carBora section contains idling fire and white smoke, mainly considering the following reasons. The first common aspect is whether the ignition defect caused by the addition of ordinary inferior gasoline to the oil quality problem is a failure. The second common problem is that the ignition system failure mainly includes leakage of the ignition coil, too large gap of the spark plug, and poor ignition.
The third aspect is mainly the group side, which mainly includes the problem of poor combustion caused by throttle deposition, fuel injector deposition and in-cylinder carbon deposition. The fourth aspect is not to say, mainly consider the sensor aspect, generally only the old oxygen sensor.
There is no white smoke when you turn it on, and there will be white smoke when you stop here for three minutes or five minutes.
In this case, the main consideration is the problem of the fuel injector, you can carry out the fuel injector then Shen San, if the fuel injector atomization is poor, it is easy to blindly erect Sun Shi in this situation.
Whew. Hmmm, okay.
In this case, he is not burning engine oil, this situation is not burning engine oil.
Okay. It's not about burning engine oil.
Uh-huh, yes. Hmmm, okay.

Anonymous users2024-02-12Blue smoke from a cold start indicates that the engine has burned oil.
If there is only a small amount of blue smoke coming out when the car is started cold, it can be used for the time being, and it is generally a fault of the valve seal. Due to the long-term use of the valve seal, the valve oil seal is aged and worn severely, 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 starting the engine, the oil in the cylinder will burn under the action of high temperature and high pressure to produce a large amount of blue smoke, this fault only needs to replace the valve oil seal.
After this kind of failure, it is recommended to check the oil level every half a month, if you find that the oil consumption has increased significantly, it is best to go to the 4S shop for on-site maintenance in time.

Anonymous users2024-02-11Hello, this situation is caused by burning engine oil, which is generally caused by turbocharging damage, aging of valve oil seals, and piston ring wear. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】
You go to the second-hand car market to take a look Then there must be a Bora I used to drive a Bora The acceleration is really good Very flexible It's really a good car The appearance is also the classic style of Volkswagen The integrated rectangular headlights are very powerful Later, I changed the horse 6 and didn't have that feeling My car sold to the second-hand car market I bought it in 03 and sold it in 06 The car was in good condition at the time When it was sold, the odometer was 90,000 kilometers 90,002 was processed What you want should be Bora R version This car is better than the ordinary ** of the year is also more expensive I estimate that the 60,000 kilometers of Bora R will be about 13w Support you to buy Bora I will regret selling Bora!
And the difference:
The engine has a turbocharging device, that is, when the speed reaches more than 2000 rpm, the supercharging device works, and the wheel output power of the engine is equivalent to the left and right displacement of the engine, and the power is stronger than the ordinary engine. If it is the same type of car and is operated in the city, the engine is a little better than the power. In other words, each has its own benefits, mainly depending on the use. >>>More
I'm glad to answer your questions again, if you choose between and, it mainly depends on your current financial situation, if the rice is sufficient, it's good, and the specific benefits are here"t"Above. I will briefly say that the meaning of this is that the displacement of the engine is, and the working mode is exhaust gas turbocharging, where T stands for Turbo in English, that is, basically the models with T are turbocharged. The working mode of automobile engine is divided into two kinds, namely naturally aspirated and turbocharged, of which turbocharging is divided into exhaust gas turbocharging and mechanical supercharging, the general supercharged engine can greatly improve the torque and power of the engine under the same displacement, such as the engine is equivalent to the power and torque of the general left and right engines, and the fuel consumption is even lower. >>>More
<>T is the abbreviation of Turbo, and if the car has Turbo or T written on the rear, it means that the engine used in the car is turbocharged. It is a turbocharged engine with a displacement of liters. >>>More
