1. Reasons. 1.The flammable mixture is too thick.
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.

It can play a role in cleaning up carbon deposits, and in a certain sense, it can improve motivation.

Add the agent first and then refuel, 50-60 liters of oil plus 100mm green beat to clear the strength optimizer, reduce the gear pull high-speed ** speedometer 3000-3500 rpm) run a distance of 50-100 kilometers, tremble to the detection station does not turn off, when waiting in line, the neutral gear rush 3000-3500 rpm 15-20 minutes.

Long-term use of "Green Energy" fuel optimizer can have a good maintenance effect on the engine of the car, and at the same time, it has a significant effect on reducing fuel consumption, improving the power of the engine, and reducing exhaust emissions.
-
The purpose of the green fuel optimizer is to make up for the quality problems of the fuel itself and the shortcomings of the manufacturing limit of motor vehicle machinery, so as to overcome the cold shock effect and gap effect of the gasoline engine, remove the carbon deposits of the intake valve and electric nozzle, and overcome the problems of the fuel injector being more fine atomization and the post-dripping of residual oil for the gasoline engine, so as to achieve a more complete and complete combustion of the fuel, so as to achieve the effects of removing carbon deposits, saving fuel, reducing emissions, and enhancing the power of Zen Qi Feng.

Frequent testing of exhaust pollutant emissions from motor vehicles is an important means to ensure that motor vehicles meet emission standards and prevent and control motor vehicle pollution. The test is usually carried out in accordance with the experimental method specified in the standard. The main detection methods are:
Idle method Double idle method: A simple portable gas analyzer is used to check the pollutant emission concentration of gasoline vehicles under idle conditions. The disadvantage is that it can only detect the concentration of carbon monoxide and hydrocarbons.
Working condition method Simple working condition method: The working condition method is to simulate the actual operating conditions of the vehicle on the road (such as idling, acceleration, constant speed, deceleration), and measure the emission of its pollutants at the same time, and the measured emission results can basically reflect the actual emission of the vehicle, which is recognized as the most scientific test method for evaluating the emission status of the automobile (or engine). However, the working condition method is expensive, the test conditions are rigorous, and the test time is long, so it is generally only used for emission detection of new stereotyped cars and new production vehicles.
The simple working condition method is to "drive" the vehicle on a chassis dynamometer at a specified speed, while its pollutant emissions are measured. The working conditions and test equipment adopted are simpler than those of the working method. It is often used for pollutant emission detection in vehicles in use.
They can detect not only the concentration of carbon monoxide and hydrocarbons, but also the concentration of nitrogen oxides.
Free acceleration method: It is divided into filter smoke meter detection method and opaque smoke meter detection method. At present, China mainly uses a filter cigarette meter to test the soot emitted by diesel vehicles under free acceleration conditions to determine whether the combustion condition of the diesel vehicle engine in use is normal, and whether the parts related to emissions need to be repaired or maintained.
Remote sensing detection method: The remote sensing detector consists of a comprehensive analyzer, a pair of infrared light emitters and receivers, and a video camera. The remote sensing detection method uses the infrared test principle of infrared light detection instrument to detect the concentration of pollutants emitted by vehicles while driving, identify vehicles with serious pollutant emissions, and shoot the license plate of the vehicle with a camera.

At present, many exhaust emissions of diesel vehicles are not up to the mark, and a solution has been found for this problem, after the use of green diesel optimizer, the simple steady-state working condition method (diesel) measured results: vehicle model Aoling, license plate number Yue B418G5 (blue), vehicle registration date 2004-7-29, 100% point before dosing is point is point is, 100% point after dosing is point is point is, decline rate (%) 100% point is % point is % point is % point is 94%. The above content is the measured result of the simple steady-state method (diesel).

Fuel oil is the main source of urban air pollution due to poor oil quality, poor atomization, and insufficient combustion, forming a large amount of soot and eliminating a large number of harmful gases. Green Fuel Optimizer effectively reduces the emission of harmful substances.
What's more unique is that the "Green Energy" fuel optimizer solves the current problem of automobile exhaust treatment: CH and NOx emissions are greatly reduced at the same time. After long-term use.
I hope it can help you, and if you don't understand, you can continue to ask.
