What does China V diesel mean, and what is the difference between China V and China VI?

Hello, China V diesel refers to the diesel engine, the emission standard meets the emission standard of China V, and now the diesel engine of China V is required to fully replace the diesel engine of China IV, and the emission is lower.

Hello, this means that the emission standard meets the national emission standard of the engine of the fifth standard, the emission pollution is less, and this is also a trend at present, and it will slowly begin to be popularized.

Hello! China V diesel engine means that this engine meets the China V emission standard. At present, some areas have implemented the national five standard.

Corrosive, fluid, emitting less exhaust gases, evaporative, and less polluting. If you compare from a professional point of view, you should compare from the anti-knock resistance of diesel, the quality of China V oil is higher, the main difference between China IV and China V diesel is simply the quality of diesel.

The meaning of China V is that the current environmental protection standard is the emission standard of China V, which is relatively high, and diesel does not have this standard yet.

Hello, the diesel fuel of China V represents the emission standard of China V, which is in line with the use of vehicles in China V.

Hello, this National V diesel is the emission standard of diesel combustion, which needs to meet the emission standard of China V.

The meaning of this national five diesel is very simple, that is to say, the label of your diesel fuel is relatively normal if it meets the emission standards of national five.

Hello, the diesel of China V represents this kind of diesel, which is used by cars that meet the emission standards of China V vehicles.

Hello, the words of China V diesel are to explain this fuel emission standard, indicating that this fuel has reached this level.

Hello, this refers to the emission standard, the exhaust emissions have reached the national five standard, but there should be no national five diesel engine now.

Hello, China 5 and China 4 or country number? This is the exhaust emission standard stipulated by the state, and the national five diesel indicates that the diesel meets the national standard.

The diesel engine of China V is in line with the national V emission standard, which is marked on the car's certificate.

The so-called China V is the current environmental protection emission standard, and the National V diesel can consider Ford models.

Hello, this means that your car is a diesel vehicle that belongs to the National V emission standard.

1. The quality of the oil is different.

The so-called "China VI" standard gasoline and diesel is better than the "China V" standard in terms of oil quality emission data, which can reduce more particulate matter and reduce more emissions of non-methane organic gases and nitrogen oxides. Overall, compared with "China V", the "China VI" emission limit will be tightened by about 40% to 50%, and the same standard is for diesel vehicles.

2. Nitrogen oxide emissions are different.

For gasoline vehicles, China V has increased the requirements for nitrogen oxide emissions, and has also added the detection of particulate matter concentration of gasoline vehicles directly injected in the cylinder. For diesel vehicles, many indicators have been greatly improved, of which the concentration of particulate matter is 82%. It's also very eye-catching.

3. The emission limits are different.

According to some data, compared with the China V standard gasoline and diesel, the carbon monoxide emissions of China VI oil products are reduced by 50%, the emission limit of total hydrocarbons and non-methane total hydrocarbons is reduced by 50%, and the emission limit of nitrogen oxides is tightened by 42%. It is a big leap forward for environmental protection.

Compared with the China V engine, the power of the National VI engine is actually reduced, and the fuel consumption is improved. For example, a luxury brand calibrated the national six national five models, simply take the 000 acceleration results, the national five acceleration can run into 6 seconds, and the national six will be thrown out of 6 seconds, not only that, but the fuel consumption performance is also higher than the national five.

What is the difference between China V and China VI?

Hello, the emission standards are not the same, and the national 6 prohibited area is small.

National V diesel standard color, oxidation, stability, sulfur content, acidity 7mgkoh U002F100ml, 10 vapor residue, residual carbon, no mechanical impurities, polycyclic aromatic hydrocarbon content 11, flash point (closed, evaporation temperature, evaporation temperature, evaporation temperature, evaporation temperature: 365. The following is the extended information: 1. Explosion resistance:

Depends on the cetane number Qi Qi. If the cetane number is low, the fuel is difficult to ignite, the lag period is long, and the engine works unsteadily, on the contrary, the ignition performance is good, the stall period is short, the combustion is uniform, and the work is stable, and the cetane number is too high, which will lead to incomplete local combustion and black smoke. 2. Evaporation:

The evaluation index of evaporability is distillation range and flash point. 50. The lower the evaporation temperature, the more light fractions in the oil, and the diesel engine is easy to start. The lower the evaporation temperature of 90 and 95, the lower the distillation temperature of the oil.

The national standard stipulates that the flash point of -35 and -50 light diesel oil shall not be less than 45. 3. Fluidity: The evaluation index of fluidity is viscosity, freezing point and cold filter point.

If the viscosity is too small, it is easy to leak from the gap between the plunger and the pump barrel of the high-pressure oil pump, and if the viscosity is too large, it will cause oil supply difficulties. 4. Corrosive pants: The evaluation index of corrosiveness is sulfur-containing compounds and sulfur content.

The evaluation index of stability was total insoluble matter and 10 residues of steamed beard pat.

The China V diesel standard was implemented in June 2013 and repealed on January 1, 2019, with the main change in sulphur content reduced.

Differences in China's diesel standards:

1.National Diesel Standards.

China's national standards for diesel have not been formulated separately. Before 2003, China implemented the standard of ordinary diesel.

2.National No. 2 diesel standard.

Effective October 1, 2003, the standard is for sulphur content below 500 ppm (.

3.National Diesel Standards.

Implemented on October 1, 2010 and repealed on January 1, 2015, the sulfur content is lower.

4.National Diesel Standards.

It came into force on February 7, 2013 and was abolished on January 1, 2017, with the following sulfur content.

5.China V diesel standard.

In June 2013, it began to be applied to the state, and on January 1, 2019, it was abolished, and the sulfur content was below that.

6.China VI diesel standard.

Since December 23, 2016, the sulfur content standard has been below the standard, and DPF and DOC treatment technologies have been added to further reduce the particulate matter and nitrogen oxide content in the Tanmuchun emissions.

1. Generally, the density range of national standard diesel is different, and the density of different models is different. Such as: 0 diesel density, +10 diesel density, +20 diesel density, 10 diesel density, 20 diesel density, 30 diesel density, 35 diesel density, usually diesel density is calculated, so that one ton of diesel is equivalent to about 1190 liters;

2. Diesel is a compression-ignition engine (i.e., diesel engine) fuel, and it is also one of the most consumed petroleum products. Because the diesel engine has higher thermal efficiency than the gasoline engine, high power, low unit consumption of liquid material next to the combustion side, and is more economical, it is more and more widely used. It is mainly used as the power of tractors, large automobiles, diesel locomotives and civil engineering and agricultural machinery;

3. Diesel is a complex mixture of hydrocarbons, with a carbon atom count of about 10-22. It is mainly blended from diesel fractions produced by distillation, catalytic cracking, hydrocracking, viscosity reduction, coking and other processes (also need to be refined and added additives).
