Quality control indicators include: gasoline antiknock property (research octane number, motor octane number, antiknock index), sulfur content, vapor pressure, contents of olefins, aromatics, benzene content, corrosion, distillation range, etc. In January 2014, the national general motors (gm) IV standard was used. The state administration of quality supervision and inspection and the national standards commission issued the mandatory national standards for motor vehicles in phase V. The plan is to be implemented at the end of 2016. The sulfur content is the most critical environmental protection indicator in vehicle gasoline. In order to further reduce the emission of vehicle pollutants, the national V standard lowers the sulfur content limit from 50ppm in the fourth stage to 10ppm, which is 80% lower. Manganese has the potential risk to human health, and the vehicle emission control system will also have adverse effects. According to the principle of prevention, the limit value of the manganese content indicator is reduced from 8mg/L in the fourth stage to 2mg/L, which stipulates that no artificial addition is allowed. In order to further reduce the photochemical pollution caused by the evaporation of gasoline, and reduce the gas intake system of the automobile engine, the national five standard reduced the level of olefin from 28% to 24% in the fourth stage. Due to the decrease of octane number caused by the reduction of sulfur and manganese, the number of gasoline used in phase V was adjusted from 90, 93 and 97 to 89, 92 and 95 respectively. At the same time, considering the development trend of the automobile industry, the index requirements of motor gasoline are added in the standard appendices. The car engine is in the design phase, and the fuel used for the compression ratio is set. The compression ratio is a very important structural parameter of the engine, which indicates the volume of the gas at the beginning of the piston at the beginning of compression and the volume ratio of the gas volume at the end of the piston. In terms of power and economy, compression ratio should be bigger and better. The compression ratio is high, the power is good, the heat efficiency is high, the vehicle acceleration, the top speed of the car will be improved accordingly. However, the compression ratio of the gasoline engine is not too large due to the performance of the cylinder material and the vibration of gasoline combustion. In short, a high compression ratio USES a high grade fuel oil. The higher the fuel mark, the slower the oil will burn, and the lower the combustion detonation, the higher the compression ratio of the engine. On the contrary, the low-grade fuel combustion rate is faster, the combustion explosion is large, the engine compression is lower. 3. The role of securities investment "Manufacturing companies with complex and lengthy international supply chains, such as the automotive industry, could also face significant challenges. These developments could also have a significant impact on productivity growth. " During the depression, the rate of interest reduction, the expansion of money supply, stimulate economic development. During the expansion period, the interest rate increases, the money supply is reduced, and the economic development is suppressed. So, interest rates have a big impact on our lives. Central bankers must learn to speak in colloquial language The essence of the plan is to identify the objectives and the ways and means to achieve them. Therefore, how to move towards the established goal and achieve the organizational goal, the plan is undoubtedly the standard of all behaviors in the management activities. It directs people in different Spaces, time and positions to achieve their goals in an orderly fashion around a general goal. If there is no planning instruction, the manager will be shown as aimless aimlessness, and the manager will be shown as the policy decision to make decisions and make decisions. The result must be the chaos of organizational order, and the result of a lot of work. In a modern society, it can be said that almost every undertaking, every organization, and even every person's activities cannot have no blueprint.
