Motor vehicle exhaust gas is an important cause of the formation of haze, and oil quality is an important factor affecting the exhaust emissions of motor vehicles. In Beijing, the motor vehicle emissions Sensor in the haze accounted for about 31%. And reduce the sulfur content of gasoline, is to solve the car exhaust pollution, reduce the haze weather an important way.
  Beijing Municipal Environmental Protection Bureau informed that, January 1, 2017, Beijing took the lead in drinking 'Beijing six' standard gasoline. The Beijing oil upgrade, octane number does not change, mainly olefins, aromatics harmful components reduced, so the oil label has not changed, the owner refueling Suction Control Valve without cleaning the fuel tank, the new oil fuel consumption on the vehicle did not significantly affect.

  Experts on a black Audi for exhaust emissions testing. The analysis project of the exhaust gas detector is different from the project of the testing plant because the testing plant will be tested in the driving environment. According to the reporter, the data of CO (carbon monoxide), CO2 (carbon dioxide) and NO nitroxide were shown on the instrument panel in normal condition: CO was 0.22%; CO2 was 12.76%; NOX was 6ppm. The results show that the car under the idle air discharge qualified. Currently on the market of various types of gasoline 90% of the ingredients are the same, the other 10% of the ingredients are different additives, different additives are mainly different antiknock agent. In general, the higher the oil label, anti-explosive performance better. The higher the engine compression ratio, the higher the requirements for gasoline explosion resistance. The gasoline label is the ratio of the actual gasoline antiknock to the antiknock of standard gasoline. The gasoline label depends on the octane number (gasoline antiknock index), such as 92 gasoline that its octane number of not less than 92. V gasoline label, octane number and anti-explosive have been reduced, while sulfur, manganese, olefin content control more stringent. Which type of gasoline is selected by the car depends primarily on whether the compression ratio matches fuel metering valve  the octane number of the gasoline. Oil from the country Ⅳ upgrade to the country V, the label has changed, the country V standard 92 gasoline, for the original use of 93 gasoline vehicles; 95 gasoline for the original use of 97 gasoline vehicles. Beijing six standard is the main changes in environmental indicators, so the gasoline label will not change. The use of Beijing six gasoline, less pollutants emissions, it can be said that both the air or for our body are good.

   Replace the 'Beijing six' oil, the owner does not have to specifically clean the fuel tank. Beijing six standard, the sulfur content is still 10ppm, the main improvement is the gasoline in the olefin, aromatics, benzene, distillation and other components, as well as the density of diesel, polycyclic aromatic hydrocarbons. 'Beijing six' change is not the main component of gasoline, the main difference between the two is the oil content of harmful ingredients to further reduce the mixed use will not affect the performance of the car, so the oil does not need to replace the fuel tank. Similarly, other regions at the end of the oil from the country Ⅳ to upgrade to the country V, before the country plus 93 No. 93, No. 97 gasoline, you can directly mix the country V standard 92, 95 oil, fuel four or five times, Complete the 'natural upgrade', do not have to clean the fuel tank.

  According to China Automotive Technology Research Center, PetroChina and domestic and foreign authority of the test data show that the country Ⅳ upgrade to the country after the V, the impact of fuel consumption is very small. Many owners concerned about fuel consumption, Beijing oil to upgrade to Beijing after six, because the octane number does not change, the power of the car will not have a significant impact, so the fuel consumption will not be significantly changed. Speaking of fuel consumption, in fact, mainly with the owner's personal driving habits, traffic conditions, traffic conditions and other factors, good driving habits help fuel-efficient. The dynamics of cars, economy and emissions are a shift in the relationship. If the technology is not innovated, to reduce emissions, will lead to reduced power. However, oil upgrades do not involve vehicle changes, there will be no such effects. But after the oil upgrade, the vehicle's catalytic system is good. Clean gasoline less sulfur content, can reduce the sulfur catalyst, oxygen sensor damage, is conducive Pressure Sensor to the normal operation of the catalyst and oxygen sensors to reduce the exhaust of CO (carbon monoxide), HC (hydrocarbon) emissions. The use of impurities and more gasoline, you may need to regularly clean the oil, replace the spark plug, the use of clean gasoline can reduce vehicle maintenance costs.

  All vehicles are equipped with OBD vehicle self-diagnosis system. If the exhaust emissions are not up to standard, the OBD system will alarm. The length of the vehicle or run the number of kilometers, to the annual inspection, the proposed car owners to open the 4S shop or a large repair shop, to be a 'physical examination' to see whether the performance standards. For exhaust emissions, the garage uses a vehicle exhaust analyzer for testing. But this exhaust gas analyzer is not used to detect the factory professional testing equipment, testing plant equipment can detect the vehicle in the process of dynamic exhaust emissions, this instrument can only measure the vehicle idle air emissions. But it can Throttle Position Sensor be found to some extent the existence of the vehicle problems, and the corresponding repair. 'Technical Manager Wei Yongliang said,' oil upgrade, the environmental indicators improved, can reduce emissions of harmful substances in the exhaust.
